SUMMARY

On behalf of Entergy Nuclear Northeast, Inc., GZA GeoEnvironmental of New York (GZA) has completed the Q2 2010 quarterly groundwater monitoring for the Indian Point Energy Center (IPEC), culminating in this report. Interpretations of the monitoring data have been made in the context of the current Conceptual Site Model. Development of this model began at the outset of the site investigations and has been iteratively enhanced as subsequent data has become available, in part through quarterly monitoring. The report has been written with a focus on the most recent quarterly data. Relationships to prior data, more in-depth technical explanations and exceptions to generalized statements and conclusions have typically been relegated to footnotes. This report format was chosen to allow efficient assimilation of the most current data and analyses by those already familiar with the project. The footnotes contain important information and should be carefully read by all, but particularly by those less familiar with the technologies involved and the project history.

Based on the quarterly groundwater sampling data for Q2 2010, GZA concludes that groundwater contaminants continue to migrate toward the Hudson River to the West, and have not migrated off the Site to the North, East or South.

Radionuclide concentrations measured during Q2 2010 were combined with previous quarterly and post-quarterly data to compute rolling average concentrations reflective of groundwater contaminant levels over the past twelve months. These data were multiplied by the associated individual zone-specific groundwater flux values, derived from the Precipitation Mass Balance Model1, to compute yearly average radionuclide release rates to the Discharge Canal and Hudson River. The Conceptual Site Model2 (CSM), upon which this radionuclide dose computation is based, continues to be validated through: (1) groundwater elevation data downloaded quarterly from a focused set of transducer-monitored well installations; and (2) the behavior of both the Unit 1 Strontium plume and the Unit 2 Tritium plume as evaluated each quarter. These data, in our opinion, continue to support the use of the current CSM as a basis for Long Term Monitoring Program design.

The overall Tritium activity in the Unit 2 plume is generally showing a historically decreasing trend, from both qualitative and quantitative perspectives. These overall reductions are seen on Figure G-17, where the total Tritium activity has decreased by approximately 28% since Q2 2007, and 86 % when compared to the bounding level Tritium activities, even with inclusion of the current peak in total Tritium (see discussion immediately below). This overall larger trend is also evident on Figures 6 and 6A, where the shaded plume3 no longer extends downgradient to the river, as first observed in the Q2 2009 quarterly report. It is further visually evident from 1 Refer to Appendix H of the Quarter 2 2009 Quarterly Long-Term Groundwater Monitoring Report for discussion of the recalibration of the Precipitation Mass Balance Model. Precipitation and groundwater elevation data were collected onsite between 2007 and 2009 and used to compute groundwater fluxes across the site. Based on analyses of these data, it was concluded that this data set sufficiently encompassed the historical variability in groundwater elevation and flux response to seasonal and yearly precipitation variability. Therefore, maximum onsite groundwater fluxes were calculated from the elevation data, and used to conservatively recalibrate the Precipitation Mass Balance Model, as discussed and employed in the Q2 2009 Quarterly LTM Report.

2 The formulation and basis for the overall CSM and the Precipitation Mass Balance model are presented in the Hydrogeologic Site Investigation Report, January 7, 2008, prepared by GZA GeoEnvironmental, Inc, on behalf of Enercon Services, Inc., for Entergy Nuclear Northeast, Indian Point Energy Center, 450 Broadway, Buchanan, NY 10511.

3 The plume shading on Figure 6 demarks the estimated boundary that separates Tritium levels greater than 5,000 pCi/L from those below this value. This plume delineation boundary value equates to one-quarter of the drinking water standard for Tritium. Although GZA emphasizes that drinking water standards (USEPA MCLs) do not apply to the IPEC property given that there are no drinking water sources on or proximate to the site, the MCLs do provide a useful benchmark for comparisons of relative human risk. Where yearly rolling average radionuclide activity data were available for multiple depths at a given location, GZA used the highest value to develop plume delineations. This is a typical approach to represent three-dimensional contaminant data sets on two-dimensional maps.

Section 1.0 Executive Summary February 15, 2011 Page 1-2 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 Figure 6A that the core of the plume has also shown a marked decrease in concentration and extent over time in the vicinity of MW-111. These findings are consistent with our CSM, which anticipates overall decreasing trends in Tritium activity. Consistent with one of the purposes of this Report, we also point out and explain data which, when first considered, may initially appear inconsistent with the assumptions used to develop the CSM. Such examples, where Tritium has increased in recent quarters, include:

Peaks in Tritium levels have been observed in multiple sampling ports of MW-31 and MW-32 since Q1 2009, and to a lesser extent since monitoring began. This long-term variability appears to be consistent with episodic releases of Tritium historically stored in the subsurface via natural and anthropogenic Retention Mechanisms4. This conclusion is further supported by the tracer data and other analyses discussed in Section 3.6 of the Q1 2009 Long Term Monitoring Report.

While Retention Mechanisms clearly appear to impact Tritium levels as summarized above, the previous Q1 and post Q1 2010 sampling events measured more noticeable increases in Tritium levels in a number of intervals within MW-31 and MW-32, where Tritium activities peaked at levels higher than previously measured. Similarly elevated Tritium activities continued through the current Q2 and post Q2 2010 sampling events at these locations. These Q1 and Q2 2010 Tritium peaks are likely related to a Q4 2009 localized and transient Unit 2 RWST/R.O. processing skid surface spill which was first detected during routine 80-10 sampling of MH-9 in mid-January 2010.

A number of additional well locations also exhibited peaks in Tritium levels coincident with the RWST/R.O. skid surface spill, as discussed in more detail in Sections 3.4.4 and 3.4.5 below. In total, approximately 70% of the sampling intervals exhibited an increase in Tritium levels as compared to the previous, Q1 2010 quarter. An increase in the number of Unit 2 Tritium I.L. exceedances was also observed.

The number and degree of Tritium peaks measured in Q2 2010 has resulted in an increase in the Unit 2 plume total Tritium activity, as shown on Figure G-17 (Appendix G). As above, this overall increase has also been attributed to the RWST/R.O. skid surface spill.

Pursuant to the RWST/R.O. surface spill, it is further noted that Tritium activity in MH-9 quickly returned to typical background levels once the spill was addressed. It is therefore anticipated that the Tritium peaks attributed to the RWST/R.O. skid surface spill will also decrease over the next several quarters, and the graph of total Tritium activity in the Unit 2 plume should also then resume its downward trend.

Our review of data found no evidence that observed increases in Tritium activity were indicative of new, unidentified leaks in the Unit 2 SFP or other monitored Systems, Structures, or Components.

The overall Sr-90 activity within the Unit 1 plume had generally been stable to decreasing in response to the West Pool demineralization operations conducted by Entergy beginning in 2006. However, the final defueling of the Unit 1 SFPs resulted in a noticeable increase in Strontium levels proximate to the SFPs, followed by downgradient increases (see Figure 7 and 7A). This is as was predicted given the requirement to temporarily raise the pool levels for fuel rod removal, thus increasing leakage rate from the SFPs5. As expected, the levels proximate to the pool have since decreased to pre-defueling Strontium activities and it is expected that levels 4 These Retentions Mechanisms are discussed along with the CSM in the previously cited Hydrogeologic Site Investigation Report.

5 As of late 2008, all the fuel rods have been removed from the Unit 1 SFPs and the pool water has been drained. As such, the Unit 1 SFPs is no longer an active source of radionuclides to the subsurface.

Section 1.0 Executive Summary February 15, 2011 Page 1-3 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 downgradient of the pool, currently exhibiting decreasing trends approaching pre-defueling levels, will also fully return to pre-defueling levels once this transient perturbation has passed through the groundwater flow system. It is anticipated that this flushing mechanism will be protracted given the impact of partitioning on Strontium levels in the groundwater.

Based on the data and analyses provided herein, our conclusion is that the Tritium and Strontium plumes are both undergoing overall long-term reductions in activity. Given this conclusion, and the recognition that Entergy has terminated all identified leaks in the Unit 2 SFP6 and has decommissioned the Unit 1 SFPs, these plumes satisfy the requirements for Monitored Natural Attenuation (MNA), the remedial technology selected for the IPEC Site.

However, it is also concluded that, while a portion of the leakage from the above cited localized, transient spills traveled directly to the saturated groundwater regime and resulted in the observed transient peaks in radionuclide levels, additional portions of these releases likely remain above the water table as recharge to the various Retention Mechanisms. This additional unsaturated zone source recharge will likely be manifested in the future as additional non-specific peaks in radionuclide levels due to episodic releases to the groundwater flow regime from these mechanisms (e.g., from intense/prolonged precipitation events). These localized release events also interfere with the goal of resetting Site Investigation Levels (I.L.s); updating of Strontium I.L.s must therefore await return to the original Strontium baseline levels existing prior to Unit 1 defueling, and additional seasonal data is required to better assess Tritium response to precipitation-driven Retention Mechanism release variability. Therefore, the ultimate confirmation of the above conclusions will require monitoring over a number of years so as to allow ranges in seasonal variation to be adequately reflected in the monitoring data and thus demonstrate continued depletion of Tritium and Strontium from the Retention Mechanisms. In this regard, it is important to recognize that even with the somewhat increased Tritium levels currently observed due to the Unit 2 RWST/R.O. skid transient surface spill, the amount of radionuclides being released through the groundwater pathway is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

In summary, based on the data collected to date, the apparent strength of the CSM to evaluate that data, and the completion of source interdictions by Entergy, we believe all Program Objectives (see Section 3.0) are being met. These objectives are consistent with and fully encompass the guidance provided in the NEI Groundwater Protection Initiative (GPI).

6 Further justification for this conclusion can be found in Section 3.6 of the Q1 2009 Quarterly Monitoring Report as well as the Hydrogeologic Site Investigation Report. The Q1 2009 Report summarizes additional, more quantitative analyses which were completed to further investigate the integrity of the Unit 2 SFP. These analyses provide further support for the original conclusion that the Unit 2 SFP is no longer leaking. However, given the more recent behavior observed in the Unit 2 collection box data (see Section 3.6 of the Q1 2009 Long Term Monitoring Report), additional investigations/data evaluations are underway to further rule out potential Unit 2 SFP leak mechanisms. In this regard, it is noted that these analyses cannot definitively and completely rule out the possibility of a remaining small leak which could then also be supplying Tritium to the groundwater flow regime in addition to the Retention Mechanism(s) and surface spill from the process skid discussed above. While it is not possible to quantify the size of the minimum detectable leak with any degree of certainty, we believe that the maximum leak rate from the Unit 2 SFP that could potentially remain undetected by the groundwater monitoring system is less than 10 to 30 gpd (0.007 to 0.021 gallons per minute). It is also likely that if a small leak exists in the Unit 2 SFP liner, it should not get worse with time. This opinion is based on liner evaluations previously conducted by Entergy. It is further emphasized that while a leak of more than 0.02 gallons per minute should be large enough to be readily detectable with the existing Long Term Monitoring Program; this amount of Tritium release to the river is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

FINAL QUARTERLY LONG-TERM GROUNDWATER MONITORING REPORT Q2 2010 (REPORT NO. 10)

February 15, 2011 Page 2-1 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 2.0 SCOPE OF WORK During Q2 2010, GZA performed groundwater monitoring at IPEC in Buchanan, New York (Site) as part of IPECs overall Long Term Groundwater Monitoring Program (LTMP) at the Site7. The overall foundation for the development and execution of this LTMP is based on the CSM, a description of which is contained within GZAs Hydrogeologic Site Investigation Report8. The scope of work completed for this quarters monitoring is described in the Sections below. Refer to Figures 1 and 2 for a Site Location Plan and Site Plan. Figure 3 provides a Lower Hudson Valley Geologic Map and Figure 4 summarizes Current and Potential Future SSC Source Locations.

2.1 Groundwater Elevation Measurement GZA maintains a network of long-term monitoring transducers and dataloggers as part of the instrumentation located across the Site. These instruments record groundwater elevation and temperature measurements at regular time intervals9, which are then downloaded on a quarterly basis10. Transducer installation logs are presented in Appendix B.

During the quarterly sampling, GZA downloaded groundwater elevation data from the long-term monitoring transducers, which collected data over the entire duration of the quarter. The low-tide groundwater elevation data during Q2 2010 (04/09/2010) from these 22 transducers are presented in Table 2 and compared to historic minimum and maximum values on Figure 5A11.

These data demonstrate that substantial variations to the observed flow field have not occurred.

These data thus further validate the applicability of the Precipitation Mass Balance Model (PMBM) for use in subsequent radiological dose computations - see Section 3.1.

2.2 Groundwater Sampling During Q2 2010, GZA collected groundwater samples for radionuclide analysis from scheduled sampling intervals within select monitoring installations (wells) as shown in Table 3. Chains of Custody for these samples are presented in Appendix C. GZA also collected additional groundwater sample volumes to provide aliquots to the NYDEC this quarter.

7 Refer to the Quarterly Long-Term Groundwater Monitoring Report Q2-Q4 2007 (Report No. 1), dated May 2008 for Site background information and a description of the environmental setting.

8 Hydrogeologic Site Investigation Report, January 7, 2008, prepared by GZA GeoEnvironmental, Inc, on behalf of Enercon Services, Inc., for Entergy Nuclear Northeast, Indian Point Energy Center, 450 Broadway, Buchanan, NY 10511.

9 Currently, transducers record groundwater elevation and temperature readings on a 20 minute time interval so as to allow capture of tidal variability. An original, more extensive network of pressure transducers provided critical data inputs for the development of the CSM and the computation of yearly radiological dose to the Hudson River. Over the first nine quarters of the LTM program (Q2 2007 through Q2 2009) sufficient data was collected from this more extensive network of transducers to capture groundwater elevation response to seasonal and yearly precipitation variability. Therefore, starting with the Q3 2009 quarterly report, the transducer monitoring program was refocused on a select subset of locations to routinely monitor the on-Site groundwater conditions going forward. These locations were selected to provide the data required to document that groundwater flow conditions remain consistent with the CSM, thus demonstrating the veracity of the subsequent dose computations. The rationale for the specific locations and depths included in the LTMP transducer redeployment are provided in Appendix K of the Q1 2009 Quarterly Monitoring Report (Report No.5), dated July 2, 2010 and Appendix J of the Q2 2009 Quarterly Monitoring Report (Report No.6).

10 With regard to these ongoing long term monitoring locations, it is noted that the transducers have a limited life. While some of the transducers can be replaced, and have been replaced in the past, others are permanently installed in the subsurface and are no longer accessible for replacement. However, with time, the base of data upon which model validity is assessed becomes increasingly more robust. Therefore, if some of these transducers fail over time, it is not likely that replacement will be imperative.

This is because the likelihood of encountering a precipitation event substantially outside the already captured range becomes increasingly more remote with time as more data are collected. In addition, it is again emphasized that considerable conservatism has been incorporated within the model development and the dose rates computed are still far below those permitted by regulation.

11 Figure 5, which previously presented shallow and deep groundwater contours, can be found in quarterly reports prior to, and including Q2 2009. This figure is no longer required given that sufficient quarterly contour data has already been obtained (See Q2 2009 for further analysis).

Section 2.0 Scope of Work February 15, 2011 Page 2-2 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 GZA used a number of different types of pumping equipment depending upon the sampling method and the characteristics of the individual monitoring installation12.

Table 1 lists the monitoring installations sampled, the sampling depths and elevations within sampling installations, and the sampling method and equipment used.

In general, GZA implemented two basic methods of sampling to collect representative groundwater samples: the Low Flow method and a modified well volume purge method. The Low Flow method allows collection of representative groundwater samples from discrete sampling zones within a monitoring installation, while limiting the accumulation of wastewater13.

As agreed by Entergy Nuclear Northeast, the NRC, NYSDEC, and GZA, the modified traditional purge method14 allows for the collection of a representative groundwater sample from a monitoring installation after purging 1.5 volumes of water15. We implemented this method in wells where low flow sampling was not practical. Sampling Data Sheets summarizing water quality data and sampling information are presented in Appendix D.

With all of the above sampling methods, GZA used dedicated sampling equipment, including polyethylene and/or nylon tubing and submersible electric pumps to the extent practical. The use of dedicated sampling equipment limits the possibility of cross-contamination between monitoring installations and/or individual multi-level samples within a single installation. Refer to Table 1 for a summary of the sampling methods, equipment, frequency, and depths employed during this quarters groundwater monitoring round.

2.3 Vapor Containment Building Foundation Drain Sampling GZA collected a water sample from on-Site manholes MH-5, B-1 and B-6 to characterize discharge from foundation drains around and below the Unit 2 and 3 Vapor Containment Structures. These drains include both foundation drains around the building peripheries (curtain drains) as well as those around the sumps near the middle of the structures (reactor sump footing drains16).17 The Q2-2010 results for these manholes indicate an increase in Tritium activity at Unit 2 (MH-5) by a factor of two when compared to the previous sampling results (Q1 2010)18, but a decrease in Tritium levels in B-1 by a factor of approximately two when compared to the previous sampling results (Q1 2010). Cesium was detected at B-1 during Q2 2010 at levels slightly above MDC, but well below the 80-10 Effluents Program reporting limits. All radionuclides (including Tritium) were non-detect at B-6 during the Post-Q2 2010 sampling event.

12 Refer to Section 4.3 of the Final 2007 Quarterly Long-Term Groundwater Monitoring Report No. 1, dated May 2008, for sampling method and equipment selection rationale.

13 As described in: Low-Flow Sample Collection, GZA, 7/18/2007 14 As described in: Modified Traditional Groundwater Sample Collection, GZA, 7/18/2007 15 When external factors (such as well-surface-flooding from storm water runoff or overland flow of plant component leaks) might have infiltrated the top of the well and impacted ambient groundwater conditions at a specific sampling location, GZA typically purged three to five volumes of water (using the modified traditional purge method) prior to collection of a sample to attempt to obtain a representative groundwater sample.

16 We could not verify that a foundation drain exists around the reactor sump in Unit 2. The assumption that it does exist is based on the plans for Unit 3 and the similarities in construction of both units.

17 These two Unit 2 drains which discharge into MH-5, along with similar drains for Unit 3 which discharge into Manholes B-1 and B-6, form an integral part of the early leak detection monitoring network. However, sampling from these three manholes has generally been problematic for a number of reasons, but particularly due to conflicts with plant security measures which mandate that the manhole covers be permanently welded shut. Some limited access has been reestablished by modifying the manhole covers to allow for a small access opening. However, this modification still limits the ability to routinely collect samples representative of the foundation drain discharges rather than just the total flow through the storm drains. Further work is being undertaken on the manhole sampling systems to facilitate more representative sampling of these foundations drains.

18 The Q2 2010 Tritium activity at MH-5 is less than both the Q3 2009 and the Q4 2009 Tritium results. MH-9s Tritium activity showed a decreasing trend from Q3 2009 to Q1 2010 in MH-9.

Section 2.0 Scope of Work February 15, 2011 Page 2-3 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 2.4 Proactive Mid-Quarter and Confirmatory Sample Collection In response to the recent peaks in Tritium activity in multiple MW-31 and MW-32 sampling intervals, additional Post-Q2 2010 groundwater samples were collected at all sampling intervals within MW-31 and MW-32 (as well as MW-30).

The results of the confirmatory and mid-quarter samples are presented in Section 3.4 along with the quarterly data. Sampling Data Sheets summarizing water quality data and sampling information are presented in Appendix E.

2.5 Preventative Maintenance GZA performed general wellhead maintenance tasks, such as housekeeping of well vaults and roadboxes, and replacement of dedicated sampling equipment, tubing and transducers, as required.

FINAL QUARTERLY LONG-TERM GROUNDWATER MONITORING REPORT Q2 2010 (REPORT NO. 10)

February 15, 2011 Page 3-1 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 3.0 DATA EVALUATION The Long Term Monitoring Program was designed to provide data to address four main objectives:

Monitor radionuclide activities and evaluate groundwater flow rate to both detect and characterize current and potential future off-Site groundwater contaminant migration to the Hudson River, both via direct groundwater discharge to the river and through infiltration into the Discharge Canal, from abnormal radionuclide releases of liquid effluents, so as to allow computation of potential radiation dose to the public from these releases;

Monitor groundwater proximate to Systems, Structures and Components (SSCs) which exhibit a credible probability of resulting in a visually undetected release of radionuclides to the subsurface carrying an activity level of significance;

Monitor groundwater along the property boundary to confirm that contaminated groundwater is not migrating off of the property to locations other than the river; and

Monitor the groundwater plumes identified on-Site to demonstrate overall reductions in total activity over time as is consistent with the requirements of Monitored Natural Attenuation (MNA)19, the selected remediation for the IPEC Site.

These objectives are consistent with and fully encompass the guidance provided in the NEI Groundwater Protection Initiative (GPI). The following sections provide data analyses to address these four objectives.

3.1 Groundwater Mass Flux Computation As presented in the Hydrogeologic Site Investigation Report, the groundwater flow in both the upper and lower flow zones is toward the power block area from the North, East and South, with subsequent discharge to the Hudson River to the West. We estimate that groundwater flow associated with infiltration from the watershed may be as deep as 350 feet, but still ultimately discharges to the river. A corollary to this conclusion is that there is no groundwater flow, and thus no off-Site radionuclide migration from the power block area to the North, East or South.

To estimate groundwater flow (i.e., groundwater mass flux) beneath the Site, a groundwater flow model was constructed based on a precipitation mass balance analysis. This analysis is based on the precept that, on a long term average, the groundwater flowing through and discharging from the aquifer is equal to the watershed infiltration recharge; this conclusion was reached because the only substantial source of recharge to the aquifer is areal recharge derived from precipitation. The previous fifteen year average for precipitation measured at the Site is approximately 36 inches per year. Based on a USGS infiltration study20, as well as the Precipitation Mass Balance Model (PMBM) calibration21, approximately 25 percent of the 19 The selection of MNA as the remedial strategy for the Site is discussed further in the Hydrogeologic Site Investigation Report.

20 USGS. Water Use, Ground-Water Recharge and Availability, and Quality of Water in the Greenwich Area, Fairfield County, Connecticut and Westchester County, New York, 2000-2002.

21 The Precipitation Mass Balance Model (PMBM) was initially calibrated to groundwater fluxes based on a Darcys Law Model with groundwater gradients derived from Q2 2007 (June 1, 2007) low-tide groundwater elevation contours (initial reference data set).

The two models use different sets of input parameters which are not dependent or related to each other. This calibration not only verified the reasonableness of the overall groundwater flow rates predicted by the PMBM, but also allowed further discretization of the groundwater flow into upper and lower flow zones as well as flow volumes upgradient and downgradient of the Discharge Canal.

After reviewing the groundwater elevation and precipitation data from the Indian Point meteorological station over the time period from Q2 2007 to Q2 2009, it was concluded that sufficient seasonal data had been collected to encompass the majority of the precipitation variability observed over the last fifteen years. Therefore, the PMBM was also recalibrated after collecting the final full

Section 3.0 Data Evaluation February 15, 2011 Page 3-2 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 precipitation falling on pervious surfaces over the Site watershed area recharges the groundwater system via infiltration.

Since precipitation represents the driving variable for groundwater flux in the PMBM22, the yearly precipitation just prior to Q2 2010 (approximately 38 inches) was calculated and input into the recalibrated model to compute the flows used in the estimation of Q2 2010 dose values.

Based on the USGS study cited above, the aquifer recharge rate is therefore approximately 10 inches for the year prior to the Q2 2010 monitoring event. Applying this value to the pervious surfaces within the six individual groundwater flow zones shown on Figure 4, it is estimated that approximately 5 gpm of groundwater flowed into the Discharge Canal from the upper and lower zones in the previous year. In addition, approximately 9 gpm and 11 gpm of groundwater flowed into the Hudson River from the upper and lower zones, respectively. Storm water discharging into the Discharge Canal and directly into the Hudson River was estimated to be approximately 42 and 5 gpm, respectively. These flows can be further subdivided into flow zones with further detail as shown in the table in Appendix F.

3.2 Groundwater Sampling The following sections describe the groundwater sampling results and associated QA/QC protocols.

3.2.1 Groundwater Sampling Results Groundwater samples collected on behalf of Entergy during Q2 2010 were analyzed at GEL Laboratories for Tritium, Sr-90, Cs-137, Co-60, and Ni-6323.

Table 3 presents the Q2 2010 analytical results for these radionuclides. The rolling yearly averages, which are calculated using all the valid data from the previous year [Q3 09 through Q2 10], including Mid-Quarter and confirmatory samples, are also presented in Table 3.

Table 4 presents minimum detection concentrations (MDC), standard deviation, and I.L.s assigned to each well for the Q2-2010 analytical results. Table 5 presents historic Site groundwater analytical data. Isopleth maps of rolling averages for Tritium and Sr-90 are presented in Figures 6 and 7, respectively. Figure 8 presents a data map of rolling averages for Cs-137, Co-60, and Ni-6324.

An overall evaluation of the sample handling, shipment and analytical procedures, indicates that the quality assurance quality control protocols have been met in Q2 2010 for all of the samples, set of transducer data in Q2 2009. Data analyses demonstrated that recalibration to the Q4 2008 data set yielded the most conservative (highest dose to the river) calibration of the nine quarterly data sets obtained during the LTMP, and thus was adopted for further dose computations. The recalibration of the model to the Q4 2008 data yielded Unit 1/2 Zone and total groundwater fluxes approximately 40% and 25% greater, respectively, than the original reference (Q2 2007) data set. Further information and the data analyses are provided in the Q2 2009 LTM report.

22 To continue to validate the appropriateness and applicability of the PMBM, a subset of the existing transducers are being maintained and monitored quarterly as part of the Long Term Monitoring Program, starting with the Q3 2009 Quarterly Report. The primary objective of maintaining these transducers is to provide ongoing confirmatory data that demonstrate substantial changes to the on-Site groundwater flow field have not taken place and thus verify that the basic assumptions inherent in the PMBM continue to remain valid. The transducer locations are provided on Figure 5A of this quarterly report, and the rationale for the selection of these specific individual transducer locations is discussed in the Q1 and Q2 2009 quarterly reports. With regard to these ongoing long-term monitoring locations, it is noted that the transducers have a limited life. While some of the transducers can be replaced, and have been replaced in the past, others are permanently installed in the subsurface and are no longer accessible for replacement.

However, with time, the base of data upon which model validity is assessed becomes increasingly more robust. Therefore, if some of these transducers fail over time, it is not likely that replacement will be imperative. This is because the likelihood of encountering a precipitation event substantially outside the already captured range becomes increasingly more remote with time as more data is collected. In addition, it is again emphasized that considerable conservatism has been incorporated within the model development and the dose rates computed are still far below those permitted by regulation.

23 It should be noted that samples were also analyzed for gamma emitters via gamma spectroscopy. Although only Co-60 and Cs-137 are reported, gamma spectroscopy should detect and identify other gamma emitters if they became present in groundwater.

24 Isopleths were not drawn for Cs-137, Co-60, and Ni-63 because the few positive detections observed did not indicate the existence of a groundwater plume containing these radionuclides. This is likely a result of the high surface affinity (highly adsorptive nature) of these radionuclides for solid geological materials. They therefore tend to rapidly partition out of the groundwater.

Section 3.0 Data Evaluation February 15, 2011 Page 3-3 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 and the analytical results should be useable as presented in Table 5. This conclusion is further supported by a review of the Q2 2010 analytical data, as compared to previous historical trends.

Refer to Section 5.2.2 of the Final 2007 Quarterly Long-Term Groundwater Monitoring Report No. 1 for further details pursuant to quality assurance quality control protocols.

3.3 Radionuclide Release Rates The recalibrated PMBM-derived groundwater flows within each of the six flow zones are multiplied by yearly rolling average radionuclide levels within each zone to compute groundwater radionuclide release rates to the Discharge Canal and Hudson River. These groundwater radionuclide release rates are computed separately for upper and lower flow zones as well as upgradient and downgradient of the Discharge Canal. The selection of specific monitoring locations for each of the six zones is described in the January 25, 2008 Memorandum - Synopsis of Long Term Monitoring Plan Bases.

Storm drain flows25 computed based on yearly precipitation rates are multiplied by radionuclide concentrations measured in the storm drains to compute the associated storm drain radionuclide release rates26 to the Discharge Canal and Hudson River.

The radionuclide release rates from the groundwater and storm drains to the Discharge Canal and Hudson River for Q2 2010 are shown in the table below.

4.11E-03 1.06E.-02

Activity in the Northern Clean Zone is attributable to an assumed Tritium background concentration of 150 pCi/L in the groundwater. The remaining radionuclides were assumed to not be present in this streamtube. Radionuclide release rate in the Southern Clean Zone is calculated from activity measured in monitoring wells MW-40 and MW-51.

- The radionuclide release rate to the Discharge Canal from the Northern Clean Zone is zero because the Discharge canal does not extend far enough to the north to be downgradient of the Northern Clean Zone.

These release rates are then used by Entergy to calculate the radiological dose to the environment via the Discharge Canal and the Hudson River using the procedure outlined in the Liquid Radioactive Effluents (0-CY-2740) document, prepared by Entergy and dated October 17, 2008.

3.4 SSCs and Property Boundary Monitoring In addition to providing the data for the dose computation discussed above, the Long Term Monitoring Program has been designed to also provide rapid detection of potential leaks from SSCs. This monitoring is specifically focused on those SSCs which exhibit a credible probability 25 The storm drain flows also include groundwater discharges from the foundation drains for Unit 2 and Unit 3 VC Buildings, but not from the Unit 1 NCD and SFDS, which are otherwise accounted for.

26 It is noted that storm drain samples are not typically taken at times coincident with peak, or even average storm drain flow rates.

By its very nature, the vast majority of the flow through the storm drain system tends to be episodic and of short duration due to storm events; sampling rounds are generally scheduled to avoid such events. Radionuclide concentrations are primarily due to groundwater infiltration into the drains and thus tend to be highest during periods of little rain when this infiltration is not diluted by the storm water flow. This incongruence therefore yields a high bias to the dose computation because the elevated concentrations associated with low flow rates are multiplied by the much higher flow rates based on total yearly rainfall.

Section 3.0 Data Evaluation February 15, 2011 Page 3-4 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 of resulting in a visually undetected release of radionuclides to the subsurface27. The monitored SSCs are shown on Figure 4 and a description of the specific monitoring installations associated with each SSC are provided in the January 25, 2008 Memorandum - Synopsis of Long Term Monitoring Plan Bases. In addition to monitoring the SSCs, on-Site and off-Site wells are used to monitor the property boundaries for unanticipated radionuclide migration across these boundaries. Again, the rationale underpinning the selection of wells designated for this purpose is provided in the above cited Memorandum. These monitoring protocols are consistent with the NEI Groundwater Protection Initiative (GPI).

Entergy is also in the planning process to add an additional multi-level monitoring installation located near the south west corner of the Unit 3 Transformer Yard, downgradient of MW-4628.

While MW-46 was previously evaluated relative to Unit 3 monitoring effectiveness, and was found to be very useful for detecting potential future releases, we also concluded that without a further monitoring well installation, there is a moderate risk that some releases could go undetected. In particular, it appears that a release in the vicinity of the Waste Holdup Tank pit could potentially proceed toward the river to the south of MW-46, given the likely hydrology associated with the pre-construction bedrock valley in this area. As such, we recommend, and Entergy agreed to, the construction of an additional monitoring installation at Unit 3 to increase the robustness of the Unit 3 well network and thus reduce this potential risk. Installation of this well is currently scheduled for 2011. The sampling of U1-NCD and U1-SFDS will also be continued as part of the Long Term Monitoring Program.

I.L.s were established for the associated monitoring wells to set quantitative radionuclide concentrations above which further action would be undertaken. As part of the ongoing groundwater monitoring program, the reported analytical concentrations are compared against I.L.s established based on the criteria shown in the table below. I.L.s are currently computed each year based on yearly averages of all the valid groundwater sampling analytical results of the previous year including Aliquot, Confirmatory, and Mid-Quarter sample results29. The monitoring well-specific I.L.s are presented in Table 4 and are established for comparison with 2010 analytical results based on the quarterly samples collected and analyzed in 2009.

27 As discussed further in the following sections, reporting of visually identified spills/leaks within structures is included within Condition Reports under Entergys Corrective Action Program. Additional emphasis has been placed on routine review of these reports as they potentially relate to GPI objectives.

28 A cross section has also previously been developed through the Unit 3 area to supplement Figure 4 and further demonstrate the relationship of site groundwater flow patterns and monitoring well placement relative to the individual Unit 3 SSCs (similar cross sections were previously developed for Units 1 and 2, as presented in the Hydrogeologic Site Investigation Report). This Unit 3 cross section C-C is included in the Q1 2009 Quarterly Report as Figure 4A.

29 The calculation of ILs and yearly rolling averages prior to the Q1 2009 Report were based on the analytical results from the quarterly sampling rounds only, and therefore excluded aliquot, confirmatory and mid-quarter sample results. For the Q1 2009 Report and thereafter, if an aliquot analytical result confirms that the original quarterly analytical result was false, then only the aliquot result is utilized in the yearly IL calculation. If the aliquot result confirms the original quarterly result is valid, then both the original and the aliquot results are averaged together and then averaged into the yearly IL calculation as a single value.

Confirmatory analytical results have the potential to impact the use of the original quarterly sample in the same manner as aliquots; however, unlike aliquots, these independent samples are averaged directly into the yearly rolling average without pre-averaging with the associated quarterly sample. Similar to confirmatory samples, mid-quarter samples are also averaged directly into the yearly rolling average calculation. However, mid-quarter sample results do not have any impact on the use of the initial quarterly samples as can either aliquot or confirmatory samples, as described above. In the case of both confirmatory and mid-quarter sample results, direct averaging into the yearly average of these additional results can somewhat bias the yearly average toward a particular quarter/season. However, given that confirmatory and mid-quarter samples are typically taken to confirm and/or prepare for uncharacteristically high radionuclide concentrations, this direct averaging provides a high bias to the subsequent yearly dose computations, and is thus conservative. In cases such as this where some bias inevitably will be created, establishing a conservative bias in the dose computations is considered more important than maintaining a seasonal non-bias.

A radionuclide is positively detected when the result is greater than or equal to the MDC and 3 times the 1 sigma uncertainty.

- The values of 1000 and 2000 pCi/L for H-3 and 2 pCi/L for Sr-90 have been chosen to be low enough to result in timely detection of a new release or change to an existing release and still be outside the normal expected range of sample results at these locations, to the extent possible with the currently available data over time.

- - Any positively detected radionuclide that has a result greater than 2 times the average from the previous year. However, the IL is not reached until an H-3 result is also greater than 1000 pCi/L or a Sr-90 result is also greater than 2 pCi/L.

In the event that the analytical results of a groundwater sample exceed the designated I.L., the following series of actions will be considered:

Contact the laboratory to verify that all quality control checks were satisfactory, sufficient sample volume was used; required MDCs were met, etc.;

Re-analyze Aliquots of the original sample;

Re-sample the location (Confirmatory sample) to verify the result;

Increase the frequency of sampling (Mid-Quarter samples) for this location30;

Initiate an investigation utilizing Entergys corrective action program and related resources as appropriate (e.g. site engineering / radiation protection); and

Initiation of source/ground water remediation techniques commensurate with the potential dose impact analyses and good environmental stewardship.

3.4.1 Proactive Mid Quarter Samples During the Q2 2010 monitoring period, there were no planned operations that required increased sampling. However, recent peaks in Tritium levels have been observed in multiple MW-31 and MW-32 sampling intervals; thus, additional Post-Q2 2010 groundwater samples were collected at all sampling intervals within MW-31 and MW-32 (as well as MW-30). The results of these samples are reported and discussed below along with the quarterly results.

3.4.2 Previous Q1-2010 Investigation Level Exceedances As indicated in the previous Q1 2010 Quarterly LTM Report, a comparison of the Q1 2010 analytical results to their respective I.L. values shows that the I.L.s were initially exceeded in five samples. Four of these I.L. exceedances are still ongoing, and are discussed individually in Section 3.4.4 below. The remaining I.L. exceedance (MW-31-85) was resolved during the Post Q1 2009 sampling, as summarized below. Additionally, one sampling location (U1-CSS) exceeded its I.L. in Q4 2009, with a semiannual schedule resulting in the next sample taken this quarter (Q2 2010); these data show that the Q4 2009 I.L. exceedance was resolved this quarter, as also summarized below.

30 It is noted that Mid-Quarter samples are also proactively obtained when plant operations could potentially result in an increased probability of a release to the subsurface.

Section 3.0 Data Evaluation February 15, 2011 Page 3-6 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 MW-31-85. The Q1 2010 Tritium result at this location exceeded the I.L. by a factor of nearly two. The Q1 2010 result was also the highest Tritium activity measured in MW-31-85 since the initiation of the LTMP. This exceedance was attributed to Unit 2 RWST/R.O. processing skid surface spill. It is further noted that this depth interval, the deepest in MW-31, responded to the release faster than the mid-depth interval (MW-31-63; see Section 3.4.4)31. Based on this Q1 2010 Tritium peak, a proactive mid-quarter sampling round (Post-Q1 2010) was initiated for monitoring installation MW-31, as well as MW-30 and MW-3232. The Tritium activity in this subsequent MW-31-85 sample decreased by nearly an order of magnitude, to well below the Tritium I.L. for this sampling depth interval. Additionally, both the Q2 2010 and Post-Q2 2010 Tritium results have remained below the I.L. for MW-31-8533. These data further support the conclusion that the Tritium peaks observed in Q1 2010 (both MW-31-85 and other MW-31 and MW-32 sampling intervals) are attributable to the transient surficial Unit 2 RWST/R.O.

processing skid spill first identified through 80-10 sampling of MH-9. GZA will continue to collect Mid-Quarter samples to monitor Tritium level variability in MW-31.

U1-CSS (Q4 2009). The previous Strontium activity measured at this location in Q4 2009 was slightly above the I.L. for Q4 2009. Because this well is scheduled for semiannual sampling, the Q4 2009 Strontium exceedance was not resolved until this, Q2 2010, quarterly report. The current data show the Q2 2010 Strontium activity to have decreased by a factor of nearly two, which yields a level below the 2010 Strontium I.L. for U1-CSS. Because the Q4 2009 (and also the Q2 2009) Strontium activity in this well is likely associated with the raising of the water levels and increased leakage in the Unit 1 SFPs during the previous defueling34, it was anticipated that the Strontium levels at this location would decrease to pre-defueling levels because the remaining fuel has been removed and the water drained from the Unit 1 SFPs. As anticipated, the Q2 2010 Strontium activity is similar to pre-defueling levels at this location.

3.4.3 Q2-2010 Boundary Investigation Levels A comparison of the Q2 2010 analytical results for the On and Off-Site Boundary Wells to their respective I.L. values shows that the I.L.s were not met for any of the monitoring locations.

Therefore, there was no requirement to further investigate radionuclide activity in these wells.

However, monitoring installation MW-40 and MW-51 are being further evaluated on a routine basis, as discussed below.

MW-40 and MW-51. While there have been no historic I.L. exceedances at these two southern boundary locations, and the majority of the data from this quarter (Q2 2010) fall within previous ranges (Tritium level in MW-40-46 was at a historic maximum, but still below 250 pCi/L), these monitoring locations continue to be closely scrutinized on a routine basis given the sensitivity associated with the southern power block boundary. Even though it is recognized that the peak Tritium levels detected are low (less that 350 pCi/L) and near the lower limit of detection, there 31 It is noted that the shallowest interval in MW-31 (49) did not exhibit a Tritium peak in the Q1 2010 or Post Q1 2010 samples. In fact, these quarter one samples yielded particularly low Tritium activities. However, Tritium activity peaked in Q4 2009 at a level nearly equal to the highest historically measured in this depth interval. Therefore, rather than potentially lagging deeper intervals, the Tritium peak in this shallowest interval may have preceded the deeper intervals at this location. As such, it is therefore also possible that the Q4 2009 peak in this well resulted from the Unit 2 RWST/R.O. processing skid or related activities, rather than from the storage/Retention Mechanism as it was previously attributed to in the Q4 2009 Quarterly Report.

32 This mid-quarter sampling event was also initiated, in part, due to the Q4 2009 Tritium peak in MW-31-49, as well as the overall Tritium variability historically observed in MW-30, 31 and 32.

33 It is noted that an increasing trend is observed in the Tritium activity data during the Q2 2010 and Post-Q2 2010 sampling rounds; however, these results are still less than the Q1 2010Tritium result by a factor of two. This subsequent increasing trend is likely due to prior recharge of the Retention Mechanisms by the original RWST/R.O. processing skid spill, resulting in further subsequent releases from these Retention Mechanisms into the groundwater flow regime.

34 The U1-CSS monitoring well is located downgradient of the Unit 1 SFPs, and appears to be situated along an anthropogenic preferential flow path. This well was installed through the East wall of the Containment Spray Sump. It is therefore located directly below the utility trench associated with this system as well as that associated with the historical discharge pipe for the Unit 1 NCD.

Section 3.0 Data Evaluation appears to be a general correlation in Tritium peaks at multiple depth intervals in both of these monitoring installations (see Figure H1 in Appendix H). An appropriate metric to evaluate whether or not these peaks are due to groundwater migration of Tritium from the power block area is the relative groundwater elevations between these locations and the power block areas where Tritium contamination exists. As discussed at length in the CSM sections of the Site Investigation Report, southern boundary groundwater elevations are well above those in the power block area. As such, groundwater, and thus Tritium in the groundwater, cannot migrate from the power block to the south; in fact, groundwater is migrating in the opposite direction.

This conclusion was previously validated for nine quarters (between Q2 2007 and Q2 2009) through analyses of groundwater elevation contours (see Figure 5 in the quarterly reports prior to Q3 2009). In addition, starting with the Q1 2009 Quarterly Report, Figure 5A is being generated to specifically compare high importance transducer readings to historic maximum and minimum readings. The objective of this analysis is to demonstrate that substantial changes to the on-site groundwater flow field have not taken place and that the CSM remains valid.

Multiple sampling zones from both the MW-40 and MW-51 monitoring installations are included in this analysis. Based on these analyses, as well as the substantial body of data developed over the last 5 years of investigation which underpin our CSM, we state, with a high degree of confidence that the low level peaks in the Tritium activities observed in these two monitoring installations are not due to groundwater migration from the power block area. This conclusion has continued to be validated each quarter. However, we do not have a definitive explanation for the observed peaks. Further investigation into other potential mechanisms, such as atmospheric Tritium washout and seasonal laboratory biases are ongoing.

3.4.4 Q2 2010 SSC Investigation Levels For the SSC monitoring wells, a comparison of the Q2 2010 and Post-Q2 2010 analytical results to their respective I.L. values shows that the I.L.s were met at ten sampling locations. The following table summarizes the cases where the I.L.s were met, with these exceedances individually discussed below.

MW-31-63. Following the Post-Q1-2010 sample at this location (highest measured Tritium activity since the initiation of the LTMP), the Q2 2010 Tritium results at MW-31-63 showed a four-fold decrease, to levels well below the I.L. However, another Tritium peak was observed in the Post-Q2 2010 results, with Tritium activity back above the I.L. These peaks in Tritium activity were likely due to a localized, transient surface spill during Unit 2 RWST/R.O.

Section 3.0 Data Evaluation February 15, 2011 Page 3-8 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 processing skid operation in Q4 200935. This release was first detected during routine 80-10 sampling of MH-9 in January, 201036. Given that the apparent source of this peak has been terminated and Tritium levels quickly returned to pre-release levels in MH-9, decreases in Tritium level to below the I.L., are expected in MW-31-63 once the residual impact of the RWST/R.O. spill, as mediated through the Retention Mechanisms, has subsided (see further discussion below and in Section 3.4.5).

In this regard, it is noted that peaks in Tritium level, likely related to mobilization of historically stored Tritium37 (Retention Mechanism), have been noted in MW-31-63 since the Q1 2009 sampling event, with somewhat less, but still noticeable variability evident all the way back to the beginning of monitoring. This behavior has also been noted in other sampling depths at this location as well as at proximate locations MW-32 and MW-30, particularly at shallower depth intervals38. Therefore, while the transient RWST/R.O. processing skid source had been terminated prior to the Tritium peak observed in the Post-Q2 2010 sample, this subsequent peak is still likely due to the spill through replenishment of the Retention Mechanisms, thus resulting in further releases from these Retention Mechanisms into the groundwater flow regime. Therefore, future Tritium increases at this sampling location due to the transient RWST/R.O. processing skid spill are still likely. As such, this location will be subject to added scrutiny during the upcoming quarterly monitoring rounds to better evaluate its variable Tritium activity.

MW-32-59. Similar to the Q1 2010 and Post-Q1 2010 samples, both the Q2 2010 and Post-Q2 2010 Tritium results at this sampling location exceeded the Tritium I.L.. The Post-Q2 2010 result was the highest Tritium activity measured at this location (in all depth intervals) since the initiation of the LTMP, and exceeded the I.L. by a factor of nearly five. Similar to the MW-31 Tritium I.L. exceedances, this Tritium peak has also been attributed to the transient surface spill which occurred in Q4 2009 during Unit 2 RWST/R.O. processing skid operations. In addition to entering the subsurface through the storm drain system, this spill also entered the MW-32 well vault39, and may have penetrated the well casings, thus potentially explaining the particularly high Tritium activities observed in this shallowest interval in MW-32. Because the surface spill was transient in nature, as concluded, in part, from the MH-9 data, it is expected that the Tritium activity should again quickly decrease below the I.L. at this location. However, this expected decrease could be masked by future contributions of Tritium from the storage/Retention Mechanism(s), as discussed more fully above for MW-31-63. As such, this location will therefore be subject to added scrutiny during the upcoming quarterly monitoring round.

35 Based on forensic research conducted by Entergy, it appears that the date of the spill was November 21, 2009.

36 On January 14 th and 15 th, 2010, the Tritium levels were measured at ~85,000 pCi/L in MH-9. These levels decreased to 4,650 pCi/L in the January 19 th, 2010 sample. Typical Tritium levels prior and post-spill were ~1,500-4,000 pCi/L in MH-9. It is therefore likely that the increased Tritium measured in MW-31 and MW-32 entered the subsurface through a storm drain pathway.

37 As discussed in the January 7, 2008 Hydrogeologic Site Investigation Report, it has been concluded that portions of the Tritium released prior to Energys last remediation interdiction (rectifying the Transfer Canal liner weld imperfection in December 2007 - the final identified leak) have been stored in the subsurface (Retention Mechanism(s),

38 As discussed in previous quarterly reports, the historic variability in Tritium activity measured in MW-30, 31 and 32 has typically been attributed to the mobilization of Tritium stored in the shallow bedrock and/or within anthropogenic structural features. This storage/Retention Mechanism(s) was confirmed during tracer testing as described in the Hydrogeologic Site Investigation Report prepared by GZA, dated January 7, 2008, and as further supported by more recent tracer data discussed in the Q1 2009 LTM Report. Therefore, while the storage/Retention Mechanism(s) clearly contribute to the observed Tritium variability, it is equally clear that some of this variability is attributable to localized transient release events.

39 An initial sample was taken of the water remaining in the MW-32 vault on 2/1/2010. This water exhibited a Tritium activity of390,000 pCi/L. Subsequent sampling of this water in May measured residual Tritium levels of ~65,000 pCi/L prior to the water being fully removed from the vault. It is further noted that the water in the vault contained other radionuclides in addition to Tritium.

These included Co-60, Sb-125, Cs-134, Cs-137, etc. Therefore, the Q1 2010 groundwater data from wells proximate to, and downgradient of, the MH-9 and MW-32 vault release points were evaluated for detections of these radionuclides, none were found.

However, Cs-137 was detected at MW-111 in Q2 2010. While this well is located downgradient of MW-32, no other wells showed detections of Cs-137, or the other radionuclides discussed above, in Q2 2010. Cs-137 at MW-111 and downgradient of MW-111 will be closely monitored in the upcoming quarterly reports.

Section 3.0 Data Evaluation February 15, 2011 Page 3-9 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 MW-32-149. The Q2 2010 and Post-Q2 2010 Tritium activity at this location continued to increase above the Q1 2010 level to nearly ten times the I.L. in the Post-Q2 2010 sample. Only the first sample collected at this location (1/19/2007) showed a higher Tritium activity (10,500 pCi/L) than the Post-Q2 2010 sample results (9,760 pCi/L). Similar to the other MW-31 and MW-32 exceedances discussed above and below, this Tritium peak has also been attributed to the transient surface spill which occurred in Q4 2009 during Unit 2 RWST/R.O. processing skid oiperations. The quick response of this deep sampling interval to the Tritium surface release provides further evidence that the spill may have penetrated the well casings and entered the subsurface immediately proximate to the sampling installation. This conclusion is based on the previously observed behavior of this sampling interval, which had historically exhibited a relatively uniformly decreasing trend for the last three years, absent the peaks observed in shallower intervals40. As discussed above for MW-32-59, the future behavior of this sampling interval is in question and will therefore be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-32-173. Both the Q2 2010 and Post-Q2 2010 Tritium results exceeded the I.L. at this sampling location. The previous Q1 2010 sampling result also showed an increase in Tritium activity to levels near the I.L. Similar to the other MW-31 and MW-32 exceedances discussed above, this increase in Tritium levels has also been attributed to the transient surface spill which occurred in Q4 2009 during Unit 2 RWST/R.O. processing skid operations. The delayed response, compared to MW-32-59 and MW-32-149, and the shallower slope to the increasing trend at this sampling depth provide evidence that this depth interval may be responding to vertically downward migration from above. This conclusion is supported by both the four-fold higher activities measured in intervals immediately above this point, as well as the strong vertically downward gradients exhibited by the bedrock formation at this location. As discussed above, the Tritium activity at this depth interval should decrease as the Tritium activity above decreases (given the transient nature of the spill), but is likely to decrease more slowly. It is also noted that the expected decrease could be masked by future contributions of Tritium from the storage/Retention Mechanism(s), as discussed more fully above for MW-31-63. As such, this location will therefore be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-36-24. The Q2 2010 Tritium activity at this sampling location slightly exceeded the Tritium I.L. The Tritium I.L. was previously exceeded at MW-36-24 in Q3 2009; but the Q4 2009 and Q1 2010 results showed a decreasing trend over that time period. Therefore, this I.L.

exceedance is not likely related to the past exceedance. Because this sampling interval is located downgradient of MW-32, the likely source of this Tritium increase is also the transient Unit 2 RWST/R.O. processing skid surface spill. Because the probable source is terminated and Tritium is a non-sorbing radionuclide, the Tritium levels at MW-36-24 should relatively quickly decrease below the I.L. This location will be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-37-40. The Strontium result for Q2 2010 slightly exceeded the I.L. for this sampling interval. An elevated Strontium activity has been observed at MW-37-40 since Q3 2009, which has been attributed to a delayed response to the increase in water levels during defueling operations in the Unit 1 SFPs. The trend for this depth interval over the previous two years is similar to those exhibited by the intervals immediately above and below (MW-37-32 and MW-37-57), except that MW-37-40 lags in response somewhat. This time lag is likely a result of the lower hydraulic conductivity (by two to three orders of magnitude) of the bedrock accessed by this depth interval. Because MW-37-57 had already decreased to pre-defueling 40 It is also noted that the sampling interval immediately above this interval, MW-32-85, did not exhibit a Tritium peak in Q1 2010; however, the Tritium activity increased during Q2 2010 and Post-Q2-2010 to levels slightly below the Tritium I.L.

Section 3.0 Data Evaluation February 15, 2011 Page 3-10 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 levels and MW-37-32 had steadily decreased towards pre-defueling levels over the past three quarters (see Figure 7A), it is expected that the Strontium activity in MW-37-40 will begin to decrease towards pre-defueling levels over the next few quarterly monitoring rounds. This location will be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-50-42. The Q2 2010 Tritium results slightly exceeded the I.L. at this sampling location.

Similar to MW-36-2441, this monitoring location is downgradient of MW-32; and the likely source of this Tritium increase is also the transient surface spill related to Unit 2 RWST/R.O. processing skid operations. Because the probable source is terminated, the Tritium levels at MW-50-42 should decrease below the I.L. at this sampling location. This location will be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-53-82. After generally42 stable levels for the previous 3.5 years, a peak in Tritium activity was observed at this location during the Q1 2010 sampling event. Tritium levels exceeding the I.L. by slightly under a factor of two and are the highest observed since Q4 2006. The Tritium activity decreased during the Q2 2010 sampling event, but the activity at this location still exceeded the Tritium I.L. While MW-53 is not located in the groundwater flow path downgradient of the Unit 2 RWST/R.O. spill, the timing of this peak is consistent with this release. In addition, and more importantly, this location has previously been demonstrated to be down-slope of the Unit 2 RWST/R.O. spill along vadose zone flow paths, as demonstrated by the tracer testing conducted as part of the hydrogeologic site investigations (see Figure 7.2 of the Hydrogeologic Site Investigation Report, January 7, 2008). While it is noted that other monitoring locations in the vicinity of MW-53-82 did not exhibit peaks in Tritium activity during the Q1 2010 and Q2 2010 sampling events (e.g., the deeper, companion sampling interval (MW-53-120), the two sampling intervals in upgradient monitoring well MW-42 and the nearby U1-NCD monitoring location), these findings are also consistent with the tracer test data as shown in the above referenced Figure 7.2. Therefore, it appears that the Tritium peak observed in MW-53-82 is a result of the Q4 2009 Unit 2 RWST/R.O. spill. As such, this location, as well as downgradient locations, will be subject to added scrutiny during the upcoming quarterly monitoring round.

MW-111. Cesium was detected for the first time at this sampling location during Q2 2010. The Cesium activity was only slightly greater than the three times 1 sigma uncertainty level.

Therefore the Cesium detection at MW-111may be nothing more than a laboratory false positive. However, this well will be subject to further scrutiny in the next monitoring report.

U3-4D. The Q2 2010 Tritium result slightly exceeded the I.L. at this sampling location43.

Additionally, the Tritium activity during the Q1 2010 sampling event showed a noticeable increase above the lower levels seen in 2008 and 2009 at U3-4D. While it is not understood what caused this Tritium increase at U3-4D, it is possibly related to a delayed response to the Tritium increase noted in manhole A-2 and MW-45-42 in Q2 2009. As such, it would be anticipated that the Tritium levels would rapidly decrease in U3-4D, similar to A-2 and MW-45-42. This sampling location will be subject to added scrutiny during the upcoming quarterly monitoring round.

41 It is noted that MW-36-24 and MW-50-42 are similarly located proximate to the upgradient (eastern) discharge canal wall, and are likely at least somewhat connected along preferential flow paths associated with the canal wall construction (e.g., blast-fractured bedrock) and backfilling with permeable soils (Unit 2). As such, it is not surprising that these two sampling locations have shown remarkably similar Tritium trends over the past 2.5 years 42 It is noted that a clear peak in Tritium activity in this interval was measured in Q1 2009. This peak was attributed to a transient release from the Unit 1 distillation tank valves, which subsequently has appeared to have dissipated through the groundwater flow system.

43 It should be noted that the Tritium I.L. is only 1,000 pCi/L at this sampling location, and the Q2 2010 analytical results was 1,070 pCi/L. Therefore, the Q2 2010 Tritium activity at U3-4D is still five times lower than the lowest isopleth drawn for the Unit 2 Tritium plume (5,000 - 10,000 pCi/L). It is noted that there is no Tritium plume associated with Unit 3.

Section 3.0 Data Evaluation February 15, 2011 Page 3-11 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 U1 NCD AND U1-SFDS. Sampling of the Unit 1 North Curtain Drain (U1-NCD) and the Unit 1 Sphere Foundation Drain Sump (U1-SFDS) are currently included as part of the Long Term Monitoring Program. These drains have been documented to capture a large proportion of the Strontium leakage from the Unit 1 SFPs, and continue to collect groundwater containing Strontium and Cesium and direct it to treatment. These drains have also historically been assumed to collect some groundwater contaminated with Tritium from the Unit 2 SFP. This conclusion was validated by the tracer test conducted as part of the hydrogeologic site investigation (see the Hydrogeologic Site Investigation Report prepared by GZA, dated January 7, 2008). The limited amount of quarterly sampling data as well as the impact of the Unit 1 defueling operations render the setting of I.L.s for these monitoring points currently premature.

However, visual inspection of the existing data was performed and a continued decrease in Tritium levels was exhibited by the U1-SFDS data, while relatively stable (limited increase)

Tritium levels in U1-NCD are evident through Q1 201044. Strontium data from these drains continued to show decreases to pre-defueling levels, as summarized on Figure 7A.

3.4.5 Conclusions - Boundary and SSC Leak Detection Monitoring Recognizing that measured activities in the Off-Site and On-Site Boundary Wells have remained below I.L. levels, this overall data set continues to demonstrate that radionuclides are migrating toward the Hudson River to the West, and are not migrating off of the property to the North, East or South, as expected given the measured groundwater flow directions from the property periphery toward the power block area.

Given the analyses discussed above, there is also no compelling reason to believe that any new unidentified leaks have developed in the SSCs monitored relative to Unit 2 or 3. However, as discussed in the Q1 2010 Quarterly Monitoring Report, a peak in Tritium activity was measured in MH-9 during routine 80-10 Effluents Program sampling. The Q1 2010 sample from the upper-most interval of MW-32 (MW-32-59) also exceeded its I.L with the highest Tritium activity measured since the initiation of the LTMP. After further investigation by IPEC, it appears that these Tritium increases originated from a Q4 2009 localized, transient surface spill involving the Unit 2 RWST/R.O. processing skid; the temporary leakage likely emanated from connection hoses during or just after the filtration process. It appears that this transient release entered both MH-9 and the well vault for MW-32 (which employs a drain empting into MH-9), and may have also penetrated the MW-32 well casings. Both the storm drains and the well vault likely provided pathways for radionuclides to enter the subsurface. Relative to the Q1 2010 data, the Q2 2010 and Post-Q2 2010 data shows further I.L. exceedances both at deeper intervals (MW-32-173) and farther down gradient (MW-36-24 and MW-50-42), as would be expected as the spill works its way through the groundwater flow regime. These additional Tritium exceedances have also been attributed to this transient R.O. skid surface spill. Based on the above analysis, it is clear that a previously unidentified transient spill has once again successfully been identified by the LTMP.

The U2 plume45 is continuing to generally exhibit overall, long-term reductions in Tritium activity46. While Q2 2010 increases in Tritium activity have been observed in multiple monitoring locations within the delineated U2 plume, these data are consistent with both the Q4 2009 transient RWST/R.O. processing skid surface spill and the overall historic variability observed in Tritium levels attributed to episodic releases of Tritium stored in the subsurface via 44 Both the NCD and SFDS were not sampled during the Q2 2010 monitoring event.

45 It is noted that there is no Tritium plume associated with Unit 3.

46 As discussed in Section 3.5.1, it is noted that an increase has been observed in the total plume Tritium activity, as elucidated in Figure G-17. This Tritium mass increase has been attributed to the transient RO. skid surface spill, which should only temporarily increase the Unit 2 Tritium mass, with reductions back to the previous trend once the Tritium from the spill moves through the system.

Section 3.0 Data Evaluation February 15, 2011 Page 3-12 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 natural and anthropogenic Retention Mechanisms47. This conclusion is further supported by the tracer data and other analyses48 discussed in Section 3.6 of the Q1 2009 Long Term Monitoring Report.

Relative to the Unit 1 Strontium data, increased leakage was anticipated during final fuel removal from Unit 1 SFPs. This leakage was readily detected as increased Strontium in the groundwater by the Long Term Monitoring Program. The initial near-pool and subsequent downgradient Strontium increases have been routinely monitored as summarized on Figure 7A.

Currently, the near-pool and more downgradient monitoring locations have generally returned to pre-defueling Strontium levels, with outliers (such as MW-37-42, the only remaining Strontium I.L. exceedance49) expected to continue to show further decreases towards pre-defueling levels in the upcoming quarters.

Overall, GZA believes that continued monitoring will further demonstrate decreasing long term trends in groundwater contaminant activities over time for both the Unit 1 and Unit 2 plumes given the source interdictions completed by Entergy. However, ultimate confirmation of these conclusions will require monitoring over a number of years to demonstrate continued depletion of Tritium and Strontium from the Retention Mechanisms originally sourced by: (1) historic Unit 2 SFP Tritium leakage; and (2) the historic and more recent Strontium leakage due to Unit 1 defueling, as well as impacts associated with a number of localized, transient release events. It is further noted that quantification of these overall radionuclide reductions will require that ranges in seasonal variation be adequately reflected in the monitoring data and any further additions of radionuclides to the Retention Mechanisms, such as through the transient releases discussed above, be dissipated from the geohydrologic flow regime.

Given the above cited constraints, it is premature to begin recalibrating the I.L.s, which were originally established at the beginning of the LTMP in 2007. Since inception of this program, it has been observed that I.L.s have been routinely exceeded in a number of cases where subsequent data have demonstrated that no new leaks have occurred. The majority of these cases occur where the radionuclide levels are generally low and/or near their detection limits. It appears that data variability, likely due to seasonal precipitation influences and local variations in flow paths and/or other in-situ processes, is the primary cause of these false positives50, particularly pursuant to Tritium. Therefore, the basis upon which the I.L.s are computed needs to be re-evaluated in light of the long-term natural transient variability of the groundwater system in response to precipitation events, etc. Furthermore, while re-evaluation/re-setting of I.L.s is a clear goal, it is still premature given the lack of sufficient data. This is particularly true given the recent behavior in Strontium levels due to the Unit 1 defueling (see Figure 7A) and the transient Tritium releases discussed above and in the Q1 2009 Quarterly LTM Report. As such, the current I.Ls will remain in effect while a sufficient data base is acquired to allow better quantification of the natural (non-leak related) variability in the data.

Five critical conclusions can be drawn from the above summarized data and analyses:

47 These Retention Mechanisms are discussed along with the CSM in the previously cited Hydrogeologic Site Investigation Report.

48 These data and analyses further support a conclusion that the Unit 2 SFP had ceased leaking after the transfer canal pin hole leak was repaired in late 2007. However, given the more recent behavior observed in the Unit 2 collection box data (see Section 3.6 of the Q1 2009 Long Term Monitoring Report), additional investigations/data evaluations are underway to further rule out potential Unit 2 SFP leak mechanisms.

49 As discussed above, the 42 foot interval in the MW-37 monitoring installation is showing a delayed decrease in Strontium levels as compared to the depth intervals above and below. This response time lag is likely a result of the lower hydraulic conductivity (by two to three orders of magnitude) of the bedrock accessed by this depth interval.

50 In this context, false positive does not refer to an error in the actual data value. Rather, it means that the I.L exceedance in question did not result from a new release. While I.L.s are meant to be set at conservatively low values, and thus false positives should be expected, a corollary objective is to set I.L values which keep the number of false positives low enough to eliminate development of complacency.

The current CSM for the IPEC site provides a good basis for the design of the Long Term Monitoring Program; 2.

the procedures and rationale used for selecting monitoring locations for leak detection have been further validated given the clear detection of the confirmed Unit 1 SFPs increased leakage during fuel removal, the transient Q1 2009 U1 FSB distillation tank valve leak (see Q4 2009 Quarterly LTM Report for further discussion), the surficial release of Tritium to Manhole A2 in Q2 2009, and the Q4 2009 Unit 2 RWST/R.O.

increases in Strontium levels following a documented leak take longer to materialize in the groundwater than might otherwise be expected51; 4.

localized, transient Tritium spills have a pronounced short term impact on Unit 2 Tritium plume activity, with potential longer term impacts via Retention Mechanism(s); and 5.

Even with the somewhat increased Tritium levels currently observed due to the Unit 2 RWST/R.O. skid transient surface spill, the amount of radionuclides being released through the groundwater pathway is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

3.5 Plume Natural Attenuation Monitoring The fourth and final objective of the Long Term Monitoring Program is to evaluate if the groundwater plumes identified on-Site demonstrate overall reductions in total activity over time, as is consistent with the requirements of Monitored Natural Attenuation (MNA), the selected remediation for the IPEC Site52.

Given the likely ages of the SFP leaks identified and characterized during the hydrogeologic investigation, it is probable that the Unit 2 (Tritium) and Unit 1 (Strontium) plumes had reached steady state conditions prior to the beginning of the LTMP. Given that: (1) the identified leaks in the Unit 2 SFP have all been previously repaired (the last leak repaired in 2007) and; (2) the water in the Unit 1 West Pool underwent intensified demineralization (beginning in April 2006 with a reduction in Strontium levels of over 95 percent), one might expect that the plumes should have started to markedly attenuate toward zero with time. Both plumes have in fact generally shown significant levels of attenuation, when they are viewed in their entirety and past release events and expected seasonal variability in the sampling data are accounted for.

However, the attenuation has not been as rapid as we originally anticipated during time frames subsequent to the source interdictions implemented by Entergy.

In the case of the Unit 2 Tritium plume, levels have dropped markedly from the highest levels measured during the two-year hydrogeologic investigation. However, the rate of Tritium decrease with time has decreased. This rate of reduction has been difficult to predict due to the impact of natural geologic and anthropogenic Retention Mechanisms. These subsurface features have trapped and stored Tritium released during historic Unit 2 SFP leaks, and are still likely releasing this Tritium to the groundwater flow regime in an episodic manner after the physical leaks have been terminated. This conclusion is consistent with the original CSM presented in the Hydrogeologic Site Investigation Report, as further supported by the tracer test data in that report as well as subsequent tracer data, as described in Section 3.6 of the Q1 2009 Quarterly Monitoring Report, dated July 2, 2010. In addition, trend identification is further complicated by impacts associated with localized transient releases (most recently, the 51 Given the proximity of monitoring installations to documented release events, the delay in release arrival is likely due primarily to Strontium partitioning and the time required for leakage to traverse anthropogenic features.

52 The selection of MNA as the remediation for the Site is more fully discussed in the Hydrogeologic Site Investigation Report.

Section 3.0 Data Evaluation February 15, 2011 Page 3-14 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 RWST/R.O. processing skid surface spill). As described above, these transient spills have resulted in a clearly identified, increasing trend in Tritium activity in a number of wells proximate to, and downgradient of, these spills. As such, these increases do not appear to be indicative of a new leak in the Unit 2 SFP. Further discussion of this quarters data pursuant to evaluation of the Unit 2 Tritium plume MNA is provided in Section 3.5.1 below.

Relative to the Unit 1 Strontium plume, Strontium levels should drop much more slowly than Tritium levels. This is because, in addition to the Retention Mechanisms discussed above for Tritium (which also apply to Strontium), Strontium also undergoes partitioning whereby this radionuclide is adsorbed from the groundwater onto solid surfaces (both geologic and anthropogenic). When the input of Strontium to the groundwater is reduced (such as via the initial fuel pool demineralization and subsequent decommissioning) the solid surfaces desorb Strontium back into the groundwater, thus maintaining Strontium levels. Strontium partitioning is therefore expected to substantially slow plume attenuation. Despite partitioning effects, some plume attenuation was observed in response to pool demineralization prior to defueling, particularly proximate to the pool. However, defueling of Unit 1 resulted in a temporarily increase in the leakage rate of West Pool water into the formation. This was expected based on previous work on the Unit 1 SFPs, but was unavoidable given the requirement to raise the pool level for fuel rod removal53. The increased leakage rate had resulted in a noticeable increase in Strontium levels in the immediate vicinity, and downgradient of, the fuel pool. However, as more currently observed, the near-pool and more downgradient monitoring locations have generally returned to pre-defueling Strontium levels, with outliers expected to continue to show further decreases towards pre-defueling levels in the upcoming quarters, as discussed further in Section 3.5.2 below.

3.5.1 Unit 2 Tritium Plume Attenuation Qualitative Evaluation From a qualitative perspective, a reduction in overall Tritium activity in the Unit 2 plume can be seen through a comparison of the Q2 2010 delineated plume boundary (Figure 6A) to those in early LTMP quarterly reports (2207 and 2008). Not only have Tritium levels within the plume generally shown an overall, long-term decreasing trend, but the reductions over the past few quarters downgradient of the discharge canal have become particularly evident in the delineated, shaded bounds of the plume. This quarter continues the trend where the shaded plume54 no longer extends to the river as it did in previous quarters through 2008. Additionally, the rolling average Tritium activity in MW-111, indicative of the core of the plume, again continued to decrease this quarter (Q2 2010). It is currently down to almost one-half of the 50,000 pCi/L plume isopleth, which it had previously always exceeded prior to Q4 2009. This trend over time has been summarized on Figure 6A, which is a compilation of the quarterly Tritium plume maps as well as that from the Investigation Report.

53 As of late 2008, all the fuel rods have been removed from the Unit 1 SFPs and the pool water has been drained. As such, the Unit 1 SFPs is no longer an active source of radionuclides to the subsurface.

54 The plume shading on Figure 6 demarks the estimated boundary that separates Tritium levels greater than 5,000 pCi/L from those below this value. This plume delineation boundary value equates to one-quarter of the drinking water standard for Tritium.

Although GZA emphasizes that drinking water standards (USEPA MCLs) do not apply to the IPEC property given that there are no drinking water sources on or proximate to the site, the MCLs do provide a useful benchmark for comparisons of relative human risk.

Where yearly rolling average radionuclide activity data were available for multiple depths at a given location, GZA used the highest value to develop plume delineations. This is a typical approach to represent three-dimensional contaminant data sets on two-dimensional maps.

Section 3.0 Data Evaluation February 15, 2011 Page 3-15 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 Mann-Kendall Quantitative Analysis To more quantitatively evaluate MNA progress, a Mann-Kendall analysis, as referenced in USEPA Guidance for Data Quality Assessment - Practical Methods for Data Analysis,55 was performed on the Tritium levels measured through Q2 2010 at monitoring locations associated with the IP2-SFP and downgradient Unit 2 Tritium plume. This statistical technique was chosen because it is particularly well suited for data sets with a limited number of points. Each of the vertical monitoring intervals at each monitoring installation location was analyzed separately. In general, only data collected after final completion of the multi-level installation56 was used.

However, there were a number of exceptions to this generalization where open borehole and/or borehole packer testing data were also used. These data were incorporated where possible given the importance of early time data (proximate to when documented leaks were still active).

Additional, more detailed discussion relative to the basis for these analyses is provided in Section 3.6 of the Q1 2009 Quarterly LTM Report.

Graphs showing the variation in Tritium concentration over time in the immediate vicinity of the Unit 2 SFP are presented as Figures G-1, G-2 and G-3 in Appendix G, for MW-30, 31 and 32, respectively. Additional graphs are also presented in the appendix for the other monitoring locations downgradient of the Unit 2 SFP (see Figures G-4 through G-14 for MW-33 through 37, 4257, 49, 50, 5358 55 and 111) and downgradient, river boundary wells (see Figures G-15 and G-16 for MW-66 and 67, respectively). Because these two river boundary wells data sets now have the recommended minimum number of data points (ten) for the Mann-Kendall analysis method as of Q1 2010, they have been included in this quarters (Q2 2010) analysis.

The Mann-Kendall analyses for the individual monitoring points are summarized on Table G-1 in Appendix G. The table includes the results of the analysis for each depth interval (well) at each of the multi-level monitoring locations enumerated above. The table is color coded, with green shading designating wells showing a decreasing trend, yellow for no trend, and red for an increasing trend.

Comparison of Table G-1 for Q2 2010 to that from Q1 2010 demonstrates that there have been no major changes59. Of the 32 non-river-boundary intervals included on the table for Q2 2010, 55 USEPA Guidance for Data Quality Assessment - Practical Methods for Data Analysis, EPA QA/G9, QA00 UDATE; EPA/600/R-96/084, July, 2000.

56 Each borehole was completed as a multi-level installation. These multi-level completions were designed to segregate the borehole length into individual sampling zones with depth. The sampling zones were generally established to coincide with the more productive zones of the fractured bedrock and overburden (both natural soils and backfill). These sampling zones were then isolated from each other with various types of seals placed in the open borehole. The objective of the seals is to prevent vertical flow through the borehole and thus establish the same conditions in the formation which existed prior to the drilling of the borehole.

As such, the Tritium data is considered depth-discrete. It is noted that the multi-level installations at some monitoring locations were removed and replaced with upgraded systems, such as for the monitoring installation at MW-32.

57 MW-42 and MW-53 are located downgradient of the Unit 1 SFPs, rather than the Unit 2 SFP. However, these two wells were included in the analyses due to the long-standing hypothesis that the Unit 2 SFP contributes Tritium to the Unit 1 groundwater flow regime via vadose zone transport (see the graphic representation in Figure 6 herein and the discussion in the Hydrogeologic Site Investigation Report). It is noted that any decreasing Tritium trend in this area due to the termination of leaks from the Unit 2 SFP could be masked by increased leakage of Tritiated water from the Unit 1 SFPs up through the completion of defueling in November 2008, and then thereafter via the Retention Mechanism(s) and localized transient releases, as described above.

58 MW-42 and MW-53 are located downgradient of the Unit 1 SFPs, rather than the Unit 2 SFP.

59 However, it is noted that the number of wells exhibiting a decreasing trend is decreasing (i.e., changing to a no-trend status).

This issue is, in part, due to a shortcoming of the Mann Kendall analysis method, itself. This method only evaluates the number of increases relative to decreases, and does not weight the analysis relative to the magnitude of each change. Therefore, once a clearly decreasing trend, even of substantial magnitude, has reached a nearly horizontal asymptotic behavior, numerous insignificantly small positive and negative changes over time (such as due to sampling and hydrogeologic variability) can overwhelm

Section 3.0 Data Evaluation February 15, 2011 Page 3-16 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 approximately one-half (17) show a decreasing trend, as compared to 20 intervals last quarter.

Slightly less than one-half (4) of the 9 river boundary monitoring intervals show a decreasing trend. It is important to note that this group of decreasing wells includes all those located within the core of the plume with the highest Tritium concentrations (MW-30-69, MW-33 and MW-111). These high-concentration wells better represent overall plume behavior because they encompass a great percentage of the Tritium activity in the plume.

Of the 13 non-river-boundary wells shaded in yellow (exhibiting no-trend), only 3 potentially provide valid representations (as shaded) of Unit 2 plume behavior pursuant to the Unit 2 SFP.

The shading designation (in and of itself) for the others can no longer60 be used to infer conclusions relative to overall plume trend as an indicator of Unit 2 SFP integrity based on this analysis, as follows:

Three wells (MW-42-49, MW-42-78, and MW-53-82) are located downgradient of the Unit 1 SFPs, rather than the Unit 2 SFP.61 In addition, as discussed in Section 3.4.4, MW-53-82 appears to have been impacted by the more recent Unit 2 RWST/R.O. spill, as well as the priorU1 FSB valve leak.

Inspection of the graph for MW-36-24 (Figure G-7) shows a rapid and large decrease in Tritium activity at early times in this overburden (discharge canal backfill) well (from > 30,000 pCi/L to <3,000 pCi/L). This large decrease is followed by a number of small perturbations around a relatively flat trend. While it is visually clear that this well has shown a major decrease in Tritium levels since containment of the 2005 shrinkage crack leak, the Mann-Kendall analysis only evaluates the number of increases relative to decreases and does not weight the analysis relative to the magnitude of each change.

As such, visual inspection demonstrates that this location actually exhibits an overall decreasing trend, even though the analysis results in a no-trend designation (yellow shading on table). However, it is also noted that the last few quarters have shown what appear to be short-term, small peaks in the Tritium activity in this well, as likely associated with the transient Q1 2009 release from the U1 FSB distillation valves, the Q4 2009 RWST/R.O spill and/or the recent increases noted in MW-31 and MW-32.

Inspection of the graph for MW-37-22 (Figure G-8) shows a similar historical trend as exhibited by MW-36-24, as discussed above. As such, the same conclusion has been reached for this well.

the early-time string of decreasing changes, thus resulting in a switch from a decreasing trend to a no-trend status. This is particularly true when a 95% confidence interval is applied. In addition, localized, transient Tritium surface spills have been shown to result in increases in activity, which, while valid measures of plume activity, impair the ability of the trend analysis to serve as a measure of plume attenuation due to successful SFP leak termination, the intended purpose of this analysis.

60 While the Mann Kendall has many advantages for trend analysis where the number of data points is limited, it suffers from an inability to account for the magnitude of each change, only assessing the number of positive changes relative to negative changes.

This shortcoming was inconsequential at early-times when larges decreases in Tritium activity were observed in response to Entergys termination of all of the identified leaks in the Unit 2 SFP. However, now that many of the graphs of Tritium activity vs time have nearly reached a horizontal asymptote, the accumulating number of small positive and negative changes is overwhelming the early-time string of decreasing changes, thus resulting in a switch from a decreasing trend to a no-trend status. In addition, localized, transient Tritium surface spills have impaired the ability of the trend analysis to serve as a measure of plume attenuation as related to SFP leak termination, the intended purpose of this analysis.

61 MW-42 and MW-53 are located downgradient of the Unit 1 SFPs, rather than the Unit 2 SFP. However, these two wells were included in the analyses due to the long-standing hypothesis that the Unit 2 SFP contributes Tritium to the Unit 1 groundwater flow regime via vadose zone transport (see the graphic representation in Figure 6 herein and the discussion in the Hydrogeologic Site Investigation Report). It is noted that any decreasing Tritium trend in this area due to the termination of leaks from the Unit 2 SFP are more likely to be masked by increased leakage of Tritiated water from the Unit 1 SFPs up through the completion of defueling in November 2008, and then thereafter via the Retention Mechanism(s) and localized transient releases, as described above. This conclusion is based on their distance from The Unit 2 SFP and the their proximity to the Unit 1 SFPs and the Unit 1 FSB distillation tank valve leak.

Inspection of the graph for MW-50-42 (Figure G-11) shows a similar historical trend as exhibited by MW-36-24 and MW-37-22, as discussed above. As such, the same conclusion has been reached for this well.

Inspection of the graph for MW-55-24 (Figure G-13) shows a similar historical trend62 as exhibited by MW-36-24, MW-37-22 and MW-50-42, as discussed above. As such, the same conclusion has been reached for this well.

Inspection of the graph for MW-32-149 (Figure G-3) shows a relatively well behaved decreasing trend in Tritium activity, starting at the beginning of the LTMP and continuing all the way until Q1 2010. Thereafter, a distinctly increasing trend began, as correlated with the Q4 2009 transient RWST/R.O. processing skid surface spill. As such, the shift from a decreasing trend to a no-trend result from the Mann Kendall analysis appears to most probably reflect the RWST/R.O spill and not a new leak in the Unit 2 SFP.

Because this transient source has been terminated, the MW-32-149 Tritium activity will likely return to pre-spill levels, and it is anticipated that the Mann-Kendall analysis will eventually re-designate this well as decreasing trend, as it has been for all previous quarterly monitoring reports.

Inspection of the graph for MW-32-85 (Figure G-3) shows a less well behaved but similar historical trend63 as exhibited by MW-32-149, as discussed above. As such, the same conclusion has been reached for this well

Inspection of the graph for MW-55-54 (Figure G-13) shows a similar historical trend64as exhibited by MW-32-149, as discussed above. As such, the same conclusion has been reached for this well.

Two of the three remaining no-trend wells comprise the shallowest sampling ports of two monitoring locations: MW-31, and MW-32. Additionally, the only two non-river boundary monitoring intervals designated with an increasing trend are also both located in the MW-31 monitoring installation. The MW-31 and MW-32 locations are actually not located downgradient of the Unit 2 SFP from a saturated groundwater flow standpoint. Rather, they are generally located up-and cross-gradient65. The upper-most interval in MW-32 and all three intervals in MW-31 (including the lower two66 which exhibit increasing trends) have shown clear peaks in Tritium levels over the last six quarters (Q1 2009 through Q2 2010) with somewhat less, but still noticeable variability evident all the way back to the beginning of monitoring. The current and historic variability in these data can be explained by either: 1) an ongoing small episodic

(< 10L/day) leak in the Unit 2 SFP; 2) a Retention Mechanism in the saturated and 62 It is noted that MW-55-24 exhibits a similar trend to MW-36-24, except at very early times where it does not show as large a drop in Tritium activities.

63 In addition to exhibiting the impact of the RWST/R.O. spill, MW-32-85 also appears to show a response consistent with the timing of the previous U1 FSB distillation valve leak. In addition, while the Mann Kendall analysis still shows a decreasing trend for MW-32-173, this monitoring interval exhibits behavior similar to MW-32-149 and MW-32-85 relative to there response to previous transient spills.

64 While MW-55-54 exhibits a similar trend to MW-32-149, it is noted that there is a small, extended increase in Tritium activity over the middle of the graph, which is not seen in MW-32-149. This increase started prior to the documented localized, transient spills discussed above. As such, it is possible that this increase is associated with the coincident increase in Unit 2 SFP leak collection box flow rate during 2008 dry cask activities. This possible relationship is currently being investigated further.

65 While not downgradient of the SFP from a groundwater flow perspective, Tritium leakage from the SFP can still migrate to these locations via vadose zone transport above the water table along dipping bedrock fractures. During the site investigation work, a tracer test was performed which clearly demonstrated that water released proximate to the SFP foundations (adjacent to MW-30) does migrate to the east and south past MW-31 and MW-32 prior to entering the water table, and then flows with the groundwater through these wells and then to the river to the west. This vadose zone migration mechanism is discussed more fully in the Hydrogeologic Site Investigation Report.

66 It is noted that while these two intervals are the lowest in the MW-31 monitoring installation, they are both much shallower than the deeper intervals in the MW-32 installation.

Section 3.0 Data Evaluation February 15, 2011 Page 3-18 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 unsaturated zones under the SFP that can retain substantial volumes of highly Tritiated water (e.g., historic SFP leakage) for substantial amounts of time67; 3) localized, transient releases68 and/or 4) a combination of the above. While Tritium concentrations in the groundwater plume could be impacted by both an ongoing leak and the Retention Mechanisms cited above, tracer concentrations in the groundwater cannot be replenished by SFP leakage. As discussed in further detail in Section 3.6 of the Q1 2009 Quarterly Monitoring Report, the original and updated tracer data strongly support the existence of a Retention Mechanism. In addition, it would be expected that Tritium release from the Retention Mechanisms would be episodic, for example as associated with periods of increased infiltration from precipitation. Such episodic releases would be expected to result in the peaks in Tritium concentrations observed. However, it is also becoming increasingly evident that relatively recent localize, transient spills are also contributing to the observed peaks in Tritium activity.

The third remaining interval reported as no-trend, MW-30-84, is located immediately next to the SFP and generally downgradient of MW-31-63 and MW-31-85 (intervals with increasing trend). While the Mann Kendall analysis yields no trend for this interval over the full monitoring time frame, the interval actually exhibits a distinctly increasing trend beginning in the late fall of 2008. The specific reason for this increase is not known, but it is worth noting that the Tritium activity in this interval is approximately an order of magnitude below that measured in upgradient well MW-31-63 (as well as MW-31-85, both of which are exhibiting increasing trends). As such, the increasing trend in MW-30-84 could be a response to infiltration of this higher activity water over time. In addition, there are also peaks in the Tritium over time data for MW-30-84 which are consistent with the timing of the above discussed localized, transient surface spills. Finally, the beginning of the general increasing trend in Tritium activity in this well appears to predate the identified localized spills, and is coincident with the increase in Unit 2 SFP leak collection box flow rate during 2008 dry cask operations. This possible relationship is currently being investigated further.

Of the seven depth intervals in MW-67, three show no trend and three exhibit a decreasing trend (relative to only two decreasing trend intervals in Q1 2010 Quarterly Monitoring Report),

using the Mann Kendall analysis (Figure G-16). However, it is critical to note that two of the three wells showing the decreasing trend are those with the highest Tritium activities (MW-67-39 and MW-67-105); activities two to four times those in the no trend wells69. In addition, the no trend wells all have maximum Tritium activities less than 1500 pCi/L. Finally, the depth interval that shows an increasing trend (MW-67-340) is also the well with the lowest Tritium activities of all 7 intervals; it is further noted that the maximum activity measured in this interval is well below 1,000 pCi/L. It is also important to recognize that MW-67 was installed and first sampled in late 2007, well after the majority of the Unit 2 Tritium activity reduction occurred (2005 through early 2007, as exhibited by the upgradient wells). Therefore, what may have been decreasing trends in these no trend wells, cannot be reconstructed with the available limited late-time data sets.

It is currently GZAs opinion that the no and increasing trend wells in MW-67 should continue to be monitored, but the data and trend analyses that they currently provide via the Mann Kendall 67 This hypothesized Retention Mechanism is supported by our understanding of the construction methods used for the IP2-SFP and adjacent structures, evaluations of contaminant concentration variability trends over short timeframes and precipitation events, as well as the original and subsequent tracer test results, as further described in Sections 7.0 and 8.0 of the Hydrologic Site Investigation Report and the Q1 2009 monitoring report.

68 That is, any other leak or spill above the upgradient portions of the Unit 2 Tritium plume (such as the previous distillate tank valve leak first discussed in the Q1 2009 Quarterly Report and the more recent RWST/R.O. processing skid spill discussed in Section 3.4 above). While relatively infrequent and transient, these spills of radionuclides into the subsurface clearly further complicate the analyses and evaluation of long term trends as used to verify the cessation of Unit 2 SFP leakage. The impact of these releases are also becoming increasingly difficult to separate from impacts associated with the storage /Retention Mechanism(s) to which these releases also contribute. To the extent possible, these transient releases have been accounted for in the previous discussions and analyses.

69 It is also noted that all three monitoring intervals exhibiting decreasing trends are the shallowest sampling intervals within MW-67.

Section 3.0 Data Evaluation February 15, 2011 Page 3-19 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 analysis method should be of no current concern. A similar analysis and conclusions apply to the two depth intervals in MW-66 (see Figure G-15).

Based on the evaluation summarized above, the Mann-Kendall analyses of the individual depth intervals within the groundwater monitoring installations located proximate to and downgradient of the Unit 2 SFP previously have overwhelmingly supported a conclusion that the Tritium plume has exhibited an overall decreasing trend with time since monitoring began. This conclusion was clear at early-times when larges decreases in Tritium activity were observed in response to Entergys termination of all of the identified leaks in the Unit 2 SFP. However, now that many of the graphs of Tritium activity vs time have reached a horizontal asymptote, the accumulating number of small positive and negative changes is overwhelming the early-time string of decreasing changes, thus resulting in a switch from a decreasing trend to a no-trend status. In addition, localized, transient Tritium spills have impaired the ability of the trend analysis to serve as a measure of plume attenuation as related to SFP leak termination, the intended purpose of this analysis. Therefore, identification of another, more appropriate method is being investigated, particularly as the total LTMP data set becomes more robust with time. It is also important to note that the increases in Tritium activity measured in the monitoring wells have been readily explained by localized, transient surface spills which are unrelated to the Unit 2 SFP. As such, there is still currently no definitive evidence of new, unidentified leaks from the monitored Systems, Structures, or Components, including the Unit 2 SFP.

Tritium Plume Total Activity Analysis As discussed above, the individual well trend data, when viewed collectively, support a conclusion that the Tritium plume concentrations have generally been decreasing with time since monitoring began. Another method to analyze plume behavior is to compute the total Tritium activity in the plume at multiple snapshots over time. This procedure70 was implemented for each quarterly LTMP sampling round from Q2 2007 to Q2 2010. In addition, the bounding Tritium concentrations from Figure 8.1 of the Hydrogeologic Site Investigation Report71 have also been included as a starting point for the graph. These data are summarized as a histogram on Figure G-17 in Appendix G.

As can be seen from the figure, the total Tritium activity in the plume downgradient of the Unit 2 SFP has shown a distinctly decreasing trend over time. However, a noticeable increase in total Tritium mass (from a low of 0.016 Ci to a current value of 0.021 Ci) was calculated during this quarter (Q2 2010). Approximately 70% of the sampling intervals used in the total Unit 2 Tritium activity calculations recorded an increase in Tritium activity from Q1 2010 to Q2 201072. Similar to the increase in Unit 2 I.L. exceedances, this overall activity increase was likely caused by the transient surface spill related to the RWST/R.O. processing skid operations. As such, the increase in total Tritium activity is likely to be transient in nature, as was the surface spill.

However, even accounting for this current peak, the total Tritium activity in the plume has still decreased 28 percent since Q2 2007, and has decreased by 86 percent when compared to the bounding level Tritium concentrations. In addition, it is noted that prior to the current, and assumed transient, perturbation in the overall downward trend in Figure G-17, the time/activity 70 The individual sampling point Tritium concentrations were multiplied by the groundwater volumes in representative zones (discretized over area and depth), as computed using soil and bedrock effective porosities developed from the pumping and tracer tests (see the Hydrogeologic Site Investigation Report for further information).

72 It should be noted that an increase in Tritium activity for sampling locations completed in soil (backfill) have greater impacts on the total Tritium mass calculations due to difference in overburden porosity vs. bedrock porosity.

Section 3.0 Data Evaluation February 15, 2011 Page 3-20 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 data appear to be approaching a non-zero horizontal asymptote73. While the general first order plume decay is what would be expected for a plume undergoing Monitored Natural Attenuation after source termination, a non-zero asymptote suggests a continued input of Tritium into the groundwater flow regime. The data currently available lead us to believe this continuing Tritium input is likely associated with the Retention Mechanism(s) and/or localized transient releases, as described in this and earlier reports.

Conclusion-Unit 2 Tritium Plume MNA Based on the data and analyses provided above, our conclusion is that the Tritium plume associated with the historic Unit 2 SFP leaks is undergoing overall, long-term reductions in activity which are consistent with Monitored Natural Attenuation (MNA), the remedial technology selected for the IPEC Site. Given this conclusion and the recognition that Entergy has terminated all identified leaks in the Unit 2 SFP, this Unit 2 Tritium plume satisfies the requirements for Monitored Natural Attenuation74. Further justification for this conclusion can be found in Section 3.6 of the Q1 2009 Quarterly Monitoring Report as well as the Hydrogeologic Site Investigation Report.

Finally, it is important to recognize that even with the somewhat increased Tritium levels currently observed due to the Unit 2 RWST/R.O. skid transient surface spill, the amount of tritium being released through the groundwater pathway is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

3.5.2 Unit 1 Strontium Plume Attenuation Despite the effects of partitioning, as discussed above, the overall Strontium activity within the Unit 1 plume had generally shown some attenuation in response to the West Pool demineralization conducted by Entergy in preparation for defueling. This work began in 2006 and resulted in an approximately 98% reduction in Strontium in the West Pool (see Figure 7A:

U1-NCD, U1-SFDS, MW-42, U1-CSS). However, the final defueling of the Unit 1 SFPs had resulted in a noticeable increase in Strontium levels proximate to the SFPs (U1-NCD, U1-SFDS, MW-42, and U1-CSS; all of which have shown large sustained decreases since mid 2009 to pre-defueling levels). Farther downgradient (MW-53, MW-55, MW-54, MW-57, MW-50, and MW-37), increases in the Strontium plume activities were also measured, but generally after a time lag as compared to wells more proximate to the SFPs. The majority of these more downgradient monitoring locations have most recently shown decreases approaching pre-defueling levels. The farthest downgradient, river boundary wells (MW-67 and MW-62) have possibly shown Strontium activity increases in the past few quarterly sampling events. This increase, followed by a longer term decrease, is as was predicted given the requirement to temporarily raise the pool levels for fuel rod removal, thus increasing the leakage rate from the SFPs prior to fully draining the pool75.

The data for Q2 2010 indicate that the overall Strontium levels continued to exhibit a general decrease and have now reached pre-defueling levels in the immediate vicinity of the pool 73 One physical cause for a horizontal asymptote would include a persistent, unidentified leak still remaining in the Unit 2 SFP. With Tritium at approximately 30,000,000 pCi/L in the SFP, a leak directly from the pool of only approximately 10 L/day would be sufficient to provide the required Tritium input to the groundwater. However, the available data do not appear to support the existence of such a leak. The rationale underlying this conclusion is discussed more fully in Section 3.6 of the Q1 2009 Quarterly Monitoring Report. This conclusion will continue to be reassessed as new data becomes available, particularly that associated with the collection box.

74 It is noted that the previously clear attenuation of the Unit 2 tritium plume has been confounded by a number of localized, transient surface spills. Entergy is currently in the process of reviewing and addressing work practices which may have contributed to the occurrence of these spills.

75 As of late 2008, all the fuel rods have been removed from the Unit 1 SFPs and the pool water has been drained. As such, the Unit 1 SFPs is no longer an active source of radionuclides to the subsurface.

Section 3.0 Data Evaluation February 15, 2011 Page 3-21 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 (U1-NCD, MW-42, U1-SFDS, U1-CSS and MW-5376). These monitoring locations would be expected to be the first to reflect the complete decommissioning of the SFPs given their location/function. Somewhat farther downgradient, the Q2 2010 data are consistent with the tail portion of the perturbation as the previous increase in U1-SFPs leakage works its way towards the river. This behavior is most evident at monitoring locations MW-37, MW-50, MW-55 and MW-5777 where, for the most part, the maximum Strontium levels were recorded in 2009 and have decreased over the past few quarters, approaching pre-defueling activities. MW-54, however, appeared to have already exhibited a Strontium peak in Q4 2008, and then decreased back to previous levels, even though this monitoring installation is relatively far downgradient.

This behavior serves to again emphasize that the IPEC Site is located in a bedrock fracture controlled hydrologic regime78. As such, this type of localized distance-based inconsistency is to be expected and likely indicates that these wells are closer to (or within) the more pervious preferential flow pathway that is hypothesized to be responsible for the convergence and narrowing of the Tritium and Strontium plumes as they move toward the river from sources centered at widely spaced locations upgradient79.

Farther downgradient, in the vicinity of the river, increases in Strontium activity in MW-62 may be reflective of the Unit 1 SFPs defueling operations. The MW-62-138 depth interval (along with, but to a lesser extent the shallower intervals in overburden) appears to show two distinct Strontium peaks in Q1 2009 and Q4 200980. However, it is noted that the Strontium levels in this monitoring installation are all relatively low (below 3pCi/l), and this location does not appear to be proximate to (or within) the preferential flow path cited above for the Strontium plume.

Therefore, the peaks in Strontium observed may not be associated with the Unit 1 defueling, and may be due to nothing more than hydrogeological variability. The other riverfront monitoring installation downgradient of the unit 1 Strontium plume, MW-67, may also be exhibiting impacts from the Unit 1 SFPs defueling. The shallowest depth interval, MW-67-39 has shown a moderate increase in Strontium levels in Q4 2009 followed by slight decreases in Q1 2010 and Q2 2010 (trends consistent with tailing off portion of an adsorbing radionuclide) after an overall, clear decreasing trend since October 2007.

From an overall, long-term perspective, Strontium levels downgradient of the Unit 1 SFPs are generally behaving as expected. The monitoring installations closest to the SFPs (e.g.,

U1-NCD, MW-42, U1-CSS and U1-SFDS) exhibited strong peaks in Strontium activity in response to defueling, and then have decreased to pre-defueling levels. Monitoring installations farther downgradient are generally showing decreases in Strontium activity over the past three quarterly sampling rounds and are approaching pre-defueling levels (e.g., MW-37, MW-55, and MW-57). It is expected that Strontium activities in these wells will continue to decrease to pre-76 While the Q1 2010 data were somewhat higher in MW-53-82 and MW-53-120, the Q2 2010 data show a decrease to approximate pre-defueling levels. This potential Strontium peak may be due to the transient surface spill associated with Unit 2 RWST/R.O. processing skid activities.

77 Based on Q2 2010 data; both sampling intervals in this monitoring location have approximately reached pre-defueling Strontium levels..

78 While groundwater flow through the fractured bedrock at the IPEC Site is highly preferential at small areal scales, it is characterized by sufficiently interconnected small bedrock fractures to allow the hydrogeologic system to function and be modeled as a non-homogeneous, anisotropic, porous media at Site-wide scales.

79 By way of contrast, in a porous media flow regime, the centerlines of plumes that start at widely spaced locations (spaced perpendicular to the groundwater flow path) will typically remain widely spaced (although the edges of the plumes will likely move closer as the plumes get wider through dispersion). In the case of fracture flow at IPEC however, not only do the Strontium and Tritium plume centerlines converge, but the plumes also get narrower as they move downgradient. In addition, MW-50 displays high relative Strontium concentrations and fault gouge was encountered during the drilling of this well. These behaviors/data are hallmark signatures of a more highly fractured zone preferentially controlling groundwater flow and thus the migration of the contaminants therein (see the Site Hydrologic Investigation Report for further CSM-focused discussion of this issue).

80 The increase in Q1 2009 in MW-62-138 was followed by a steady decrease over the next two quarterly monitoring events, and the peak in Q4 2009 was followed by a greater magnitude decrease in Q1 2010; the Q2 2010 Strontium activity slightly increased compared to Q1 2010.

Monitoring installations closer to the river may still show Strontium increases as the additional leakage experienced during defueling flushes through the groundwater flow system. It is expected that completion of this flushing mechanism will be protracted given the aforementioned impact of partitioning on Strontium levels in the groundwater. However, over time it is expected that downgradient Strontium plume levels will also continue their overall downward trend once this perturbation has fully passed through the system; decreasing trends are expected and predicted given that Entergy has terminated all leaks in the Unit 1 SFPs through decommissioning and the Unit 1 Strontium plume continues to decrease in accord with Monitored Natural Attenuation. Given this conclusion and the recognition that Entergy has terminated all identified leaks in the Unit 1 SFPs through decommissioning, the Unit 1 Strontium plume satisfies the requirements for Monitored Natural Attenuation.

FINAL QUARTERLY LONG-TERM GROUNDWATER MONITORING REPORT Q2 2010 (REPORT NO. 10)

4.0 CONCLUSION

S AND PLANNED FUTURE WORK Given the data collected to date, the apparent strength of the CSM to evaluate those data, and the completion of source interdictions by Entergy, we believe all Program Objectives (see Section 3.0) are being met. These objectives are consistent with and fully encompass the guidance provided in the NEI Groundwater Protection Initiative (GPI).

Based on the specific results and evaluation of the Q2 2010 groundwater monitoring within the context of the Long Term Monitoring Program, IPEC plans to continue routine groundwater sampling and related maintenance. This work will be conducted in accordance with the IPEC Radiological Groundwater Monitoring Program IP-SMM-CY-110, and will incorporate the enhancements described herein.

More specifically, evaluation of data collected during Q2 2010 has shown the following:

While I.L.s have been met at a number of upgradient Unit 2 locations this quarter, there is no compelling evidence of new, unidentified leaks from the monitored Systems, Structures, or Components. The Q2 2010 and/or Post-Q2 2010 I.L. exceedances in multiple MW-31 and MW-32 sampling intervals (MW-31-63, MW-32-59, MW-32-149, and MW-32-173), as well as MW-36-24, MW-50-42, and MW-53-82 have been attributed to a localized, transient surface spill associated with operation of a Unit 2 RWST/R.O.

processing skid during Q4 2009 (see Section 3.4.5). Given that this Tritium release was eliminated, it is expected that the Tritium activities will decrease to pre-spill levels; although future releases from the storage/Retention Mechanism(s), replenished by these spills and historic SFP leaks, could create additional perturbations in Tritium levels.

Previously identified, more historic transient leaks included: the additional leakage from the Unit 1 SFPs during the 2008 defueling operations, the transient leakage from the distillation tank valves in Q1 2009, and the transient surficial Tritium release to Unit 3 Manhole A2 in Q2 2009:

Based on past work, additional leakage was expected during the raising of water levels in the Unit 1 SFPs for final fuel removal to ISFSI storage. Unit 1 SFPs leakage was terminated with the drainage and sealing of the pools. This previous, transient leakage was initially verified as pronounced increases in Strontium and Cesium in the monitoring locations closest to Unit 1, and continues to be monitored.

The Q1 2009 leakage from the distillation tank valves was independently81 identified based on an increase in Tritium levels in monitoring installation MW-42 proximate to the tanks, and subsequent increases in downgradient wells (MW-53-82, U1-CSS, and MW-50-42). These valves were immediately repaired and the leakage was terminated. Based on the observed data trends, it appears that the Tritium input into the groundwater flow regime from the waste distillation tank valving leak has generally dissipated through the system82. However, the potential impact of this 81 The valve leakage was initially identified during routine visual inspection rounds and immediately terminated. Given that the leak was within the Unit 1 FSB structure, it was documented in a Condition Report under Entergys Corrective Action Program. This valve leak and repair subsequently came to light within the GPI program during investigations into the cause of the abrupt increase in Tritium levels in MW-42. Additional emphasis has therefore been placed on routine review of these reports as they potentially relate to GPI objectives.

82 Additional portions of these releases likely remain above the water table in the release area as recharge to the various Retention Mechanisms. This additional unsaturated zone source recharge will likely be manifested in the future as additional non-specific peaks in radionuclide levels due to episodic releases to the groundwater flow regime from these mechanisms (e.g., from intense/prolonged precipitation events).

Section 4.0 Conclusions and Planned Activities February 15, 2011 Page 4-2 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 release further downgradient will be specifically scrutinized during subsequent monitoring rounds.

Elevated Tritium activity was detected in Unit 3 Manhole A2 during routine 80-10 Effluents Program sampling during Q2 2009. This manhole is located proximate to the Unit 3 FSB. Subsequent re-sampling of this manhole showed rapidly decreasing Tritium activity, indicating that this was a one-time transient event. This elevated Tritium was also detected in a proximate groundwater monitoring installation (MW-45), likely due to exfiltration of Tritium from the manhole. As of this quarter (Q2 2010) the Tritium levels in this well have returned to previous levels for three consecutive quarters. While the specific root source of the elevated Tritium is still unclear at this time, Entergy has formulated a plan to investigate a suspected SFP seasonal airborne vapor depositional source.

As such, these data support the validity of the current CSM for use as a basis for Long Term Monitoring Program design. It is further noted that, while a portion of the above four documented localized leakage events traveled directly to the saturated groundwater regime and resulted in the observed transient peaks in radionuclide levels, additional portions of these releases likely remain above the water table as recharge to the various Retention Mechanisms. This additional unsaturated zone source recharge will likely be manifested in the future as additional non-specific peaks in radionuclide levels due to episodic releases to the groundwater flow regime from these mechanisms (e.g., from intense/prolonged precipitation events).

While the current Tritium I.L. levels proved helpful both last quarter and this quarter (Q1 and Q2 2010) in identifying a localized, transient surface spill associated with Unit 2 RWST/R.O. operations, data collected during previous quarters and possibly the U3-4D I.L. exceedance this quarter (Q2 2010) have generally demonstrated that the I.L.s originally established are somewhat too sensitive relative to natural seasonal/precipitation-driven transient variations in radionuclide activities, as well as the variability inherent in the laboratory analyses. Relative to Strontium from the Unit 1 SFPs, the previous increases in activity in a number of monitoring points, due to the previous Unit 1 defueling operations, limit our ability to establish Strontium baseline levels for assessment of new I.L.s pursuant to the Monitored Natural Attenuation (MNA) of this plume. It is anticipated that this additional Strontium activity will take a number of quarters to completely flush through the onsite groundwater flow system and attenuate to reasonably stable levels. As such, the originally established I.L.s for both Tritium and Strontium will continue to be used until sufficient data is collected to allow re-evaluation of I.L. levels for the radionuclides of interest.

From both qualitative and quantitative perspectives, the overall quarterly monitoring data set supports the conclusion that the overall Tritium activity in the Unit 2 plume has been decreasing. These overall reductions have become particularly evident on the more recent quarterly report Figures 6 and 6A where the shaded plume83 no longer extends to the river, as it did prior to Q2 2009. It is further visually evident from Figure 6A that the core of the plume (with quarterly rolling average activities greater than 100,000 pCi/L 83 The plume shading on Figure 6 demarks the estimated boundary that separates Tritium levels greater than 5,000 pCi/L from those below this value. This plume delineation boundary value equates to one-quarter of the drinking water standard for Tritium.

Although GZA emphasizes that drinking water standards (USEPA MCLs) do not apply to the IPEC property given that there are no drinking water sources on or proximate to the site, the MCLs do provide a useful benchmark for comparisons of relative human risk.

Where yearly rolling average radionuclide activity data were available for multiple depths at a given location, GZA used the highest value to develop plume delineations. This is a typical approach to represent three-dimensional contaminant data sets on two-dimensional maps.

Section 4.0 Conclusions and Planned Activities February 15, 2011 Page 4-3 11-2-15 FINAL LTM 2010 Quarter Two Report.docx File No. 01.0017869.92 and 2007 bounding core activities greater than 250,000 pCi/L) has also shown a marked decrease in activity and extent. Based on the data and analyses provided above, our conclusion is that the Tritium plume associated with the historic leaks in the Unit 2 SFP is undergoing long-term, overall reductions in activity which are consistent with Monitored Natural Attenuation (MNA), the remedial technology selected for the IPEC Site84. Given this conclusion, and the recognition that Entergy has terminated all identified leaks in the Unit 2 SFP85, this Unit 2 Tritium plume satisfies the requirements for Monitored Natural Attenuation.

The overall Strontium activity within the Unit 1 plume had generally been stable or decreasing in response to West Pool demineralization conducted by Entergy beginning in 2006. However, the final defueling of the Unit 1 SFPs resulted in an initial, noticeable increase, followed by a subsequent and commensurate decrease, in Strontium levels proximate to the SFPs, with later increases in the downgradient Strontium levels (see Figure 7 and 7A). This is as was predicted given the requirement to temporarily raise the pool levels for rod removal, thus increasing leakage rate from the SFPs86. As anticipated, the levels proximate to the pool have decreased to pre-defueling Strontium levels, and levels downgradient of the pool are showing continued decreases as this additional Strontium-contaminated water flushes through the groundwater flow system.

It is expected that this flushing mechanism will be protracted given the aforementioned impact of partitioning on Strontium levels in the groundwater. However, over time it is expected that downgradient Strontium plume levels will also achieve an overall downward trend below pre-defueling levels once this perturbation is finished passing through the system. Given this conclusion and the recognition that Entergy has terminated all identified leaks in the Unit 1 SFPs through decommissioning, the Unit 1 Strontium plume satisfies the requirements for Monitored Natural Attenuation. However, as indicated above, the establishment of updated I.L.s for the Unit 1 Strontium plume must await return to the original Strontium baseline levels existing prior to Unit 1 defueling.

The amount of radionuclides being released through the groundwater pathway, even with the somewhat increased Tritium levels currently observed due to the Unit 2 RWST/R.O. skid transient surface spill, is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

84 It is noted that the previously clear attenuation of the Unit 2 tritium plume has been confounded by a number of localized, transient surface spills. Entergy is currently in the process of reviewing and addressing work practices which may have contributed to the occurrence of these spills.

85 Further justification for this conclusion can be found in Section 3.6 of the Q1 2009 Quarterly Monitoring Report as well as the Hydrogeologic Site Investigation Report. The Q1 2009 Report summarizes additional, more quantitative analyses which were completed to further investigate the integrity of the Unit 2 SFP. These analyses provide further support for the original conclusion that the Unit 2 SFP is no longer leaking. However, given the more recent behavior observed in the Unit 2 collection box data (see Section 3.6 of the Q1 2009 Long Term Monitoring Report), additional investigations/data evaluations are underway to further rule out potential Unit 2 SFP leak mechanisms. In this regard, it is noted that these analyses cannot definitively and completely rule out the possibility of a remaining small leak which could then also be supplying Tritium to the groundwater flow regime in addition to the Retention Mechanism(s) and surface spill from the process skid discussed above. While it is not possible to quantify the size the minimum detectable leak with any degree of certainty, we believe that the maximum leak rate from the Unit 2 SFP that could potentially remain undetected by the groundwater monitoring system is less than 10 to 30 gpd (0.007 to 0.021 gallons per minute). It is also likely that if a small leak exists in the Unit 2 SFP liner, it should not get worse with time, as based on liner evaluations previously conducted by Entergy. It is further emphasized that while a leak of greater than 0.02 gallons per minute should be large enough to be readily detectable with the existing Long Term Monitoring Program, this amount of Tritium release to the river is still small compared to permitted levels of Tritium discharge to the river through the Discharge Canal.

86 As of late 2008, all the fuel rods have been removed from the Unit 1 SFPs and the pool water has been drained. As such, the Unit 1 SFPs is no longer an active source of radionuclides to the subsurface.

1. For nested multi-level monitoring wells, suffix of well ID indicates depth (rounded to nearest foot) from reference point on casing to bottom of well screen.

For Waterloo multi-level systems, suffix indicates depth (rounded to nearest foot) from reference point on casing to top of sampling port. Well IDs without a suffix are open bedrock wellbores.

2. Projected sampling frequencies presented for 2010 are subject to change.

3. For nested multi-level montoring wells, interval includes well screen and sand pack. For Waterloo multi-level systems, interval includes open wellbore between bottom of 1st packer above and top of 1st packer below sampling port. For open bedrock wellbores, interval extends from bottom of casing to bottom of hole.

4. Sampling depths within sampling intervals (i.e. location of pump intake) have been located adjacent to a transmissive zone where possible.

5. Dot pattern denotes sampling interval is positioned within overburden. Open box indicates sampling interval is in bedrock.

6. These locations are storm drains.

1. For nested multi-level monitoring wells, suffix of well ID indicates depth (rounded to nearest foot) from reference point on casing to bottom of well screen. For Waterloo multi-level systems, suffix indicates depth (rounded to nearest foot) from reference point on casing to top of sampling port. Well IDs without a suffix are open bedrock wellbores.

2. All analytical results from the last 12 months from each location are provided. Monitoring locations are sampled quarterly, bi-annually, or annually, and as necessary during the year.

3. Sampling depths within sampling intervals (i.e. location of pump intake) have been located adjacent to a transmissive zone where possible.

4. Averages provided are analytical result averages of all valid samples (including mid-quarter and confirmatory samples) collected from each monitoring location from the third quarter of 2008 (Q3-2008) to the second quarter of 2009 (Q2-2009) including post Q2-2009 samples.

l Monitoring locations are sampled quarterly, bi-annually, or annually and additional samples are collected when necessary. Therefore, some results provided are the average of more than 4 samples.

For quarters in which samples were reanalyzed due to potential false positives, both results were used to calculate averages if subsequent results confirmed the validity of the original sample/analysis. For cases in which reanalysis discredited the validity of the original sample result, the replacement results were used to calculate the average. If analytical results resulted in resampling, and the resample result discredited the validity of the original sample result of a particular radionuclide, the original sample results were not used for any radionuclides and only the resample result was used. For cases in which an aliquot of the original sample was reanalyzed, if the result of the aliquot confirmed the original result, then the aliquot result and the original result were averaged and the average of the two was used to calculate the rolling average. If the aliquot result indicated the original result was false, then only the aliquot result was used to calculate the rolling average.

5. NA indicates that the constituent was not analyzed.

6. ND indicates that all of the analytical results used to calculate the average were less than MDC and/or 3 times the 1 sigma uncertainty.

7. Dot pattern denotes sampling interval is positioned within overburden. Open box indicates sampling interval is in bedrock.

8. Due to unexpectedly high levels of Co-60 detected in the original set of the 4th Quarter 2008 samples collected from MW-67-39, a second set of samples were collected and analyzed. Quality control review of the original analysis showed no evidence of error in laboratory analysis or field collection procedures and reanalysis of the original sample confirmed the Co-60 detections. However, historical data and data for the second set of samples showed results below MDC and below three times the 1 sigma uncertainty (not positive) for Co-60 at this interval, suggesting that the first set of results do not appropriately characterize activity at this interval. In addition, results from the NRC split sample of this interval were not positive. Thus, results for the first set of MW-67-39 samples during Quarter 4 were not used to calculate yearly averages.

9. These locations are storm drains.

10. Aliquots from the samples from MW-63-93, MW-63-163 and MW-63-174 were re-analyzed to investigate unexpectedly high Sr-90 results. The re-analyzed samples had results below MDC and below three times the 1 sigma uncertainty (not positive) for Sr-90 at these intervals, suggesting that the first set of results do not appropriately characterize activity at these intervals. Thus, results from the original samples were not used to calculate yearly averages.

11. The sample from MW-63-121 was reanalyzed due to unexpected Sr-90 results. The re-analyzed samples confirmed the original results, therefore the average of the original and reanalysis results was used to calculate the rolling averages.

12. Confirmatory samples were collected and analyzed to evaluate the results of the preceding sample.

13. Mid-quarter samples were collected and analyzed to evaluate the potential effect of certain operations on groundwater quality.

14. Due to unexpectedly high levels of Cs-137 detected in the original set of the First Quarter 2009 samples collected from MW-66-21 and MW-67-173, a second set of confirmatory samples were collected and analyzed. The re-analyzed samples had results below MDC and below three times the 1 sigma uncertainty (not positive) for Cs-137 at these intervals, suggesting that the first set of results do not appropriately characterize activity at these intervals. Thus, cesium results from the original samples were not used to calculate yearly averages.

1. For nested multi-level monitoring wells, suffix of well ID indicates depth (rounded to nearest foot) from reference point on casing to bottom of well screen. For Waterloo multi-level systems, suffix indicates depth (rounded to nearest foot) from reference point on casing to top of sampling port.

Well IDs without a suffix are open bedrock wellbores.

2. Sampling depths within sampling intervals (location of pump intake) have been established at location of most transmissive zone to the extent possible.

3. I.L.s (Investigation Levels) are predetermined detection limits assigned to each sampling location which, if reached or exceeded, require further investigation or action. I.L.s presented here are established for 2009 based on 2008 averages. Positive detections indicate that the the result is greater than MDC and greater than or equal to 3 times the 1 sigma uncertainty.

4. NA indicates that the constituent was not analyzed.

5. Dot pattern denotes sampling interval is positioned within overburden soils. Open box indicates sampling interval is in bedrock.

6. Shading indicates that the sample result exceeds the Investigation Level.

7. Due to unexpectedly high levels of Cs-137 detected in the original set of the First Quarter 2009 samples collected from MW-66-21 and MW-67-173, a second set of samples were collected and analyzed. The re-analyzed samples had results below MDC and below three times the 1 sigma uncertainty (not positive) for Cs-137 at these intervals, suggesting that the first set of results do not appropriately characterize activity at these intervals.

Investigation Levels have not been determined for samples collected from storm drains or manholes.

- Indicates 2010 I.L not computed for this well due to absence of 2009 data.

1. For nested multi-level monitoring wells, suffix of well ID indicates depth (rounded to nearest foot) from reference point on casing to bottom of well screen. For Waterloo multi-level systems, suffix indicates depth (rounded to nearest foot) from reference point on casing to top of sampling port Well IDs without a suffix are open bedrock wellbores (rounded to nearest foot) from reference point on casing to top of sampling port. Well IDs without a suffix are open bedrock wellbores.

2. Sampling depths within sampling intervals (location of pump intake) have been established at location of most transmissive zone to the extent possible.

3. NA indicates that the constituent was not analyzed.

4. Current well identifications are shown for each location. Minor name changes have been made based on altered transducer installations.

5. Dot pattern denotes sampling interval is positioned within overburden soils. Open box indicates sampling interval is in bedrock.

6. At monitoring well U3T1, sample IDs 019-B, 019-D, and 019-S were collected for laboratory and field QAQC (B=Blind, D=Duplicate, S-Spike). Only the duplicate sample results were included in the calculations for rolling averages.

7. These locations are storm drains, not monitoring wells.

1. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%) interstitial space (i.e. fractures).

2. The H3 bounding isopleth encompasses upper bound values measured over both depth and time through the current quarter. As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any one time. Compare bounding plume to current plume on Figure 6.

3. The Sr-90 bounding isopleth encompasses upper bound values measured over both depth and time through the current quarter. As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any one time. Compare bounding plume to current plume on Figure 7.

4. Two discrete isopleths have been drawn around MW-39 and 41 given measured Sr90 concentrations greater than 2 pCi/L. It is expected that similar concentrations exist at other locations along the legacy piping alignment in addition to the locations shown.

5. Historically elevated tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Elevated tritium levels not seen in MW-53; therefore, this transient leakage was likely to have been generally confined to, and contained by, the Unit 1 North Curtain Drain.

6. Historically elevated tritium levels in MW-45-42 observed during Q2 2009 were consistent with with a surficial release to Unit 3 Manhole A2. This release was initially detected in a storm drain sample taken 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter.

7. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a November 21, 2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

Data Notes:

1. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%) interstitial space (i.e. fractures).

2. The H3 bounding isopleth encompasses upper bound values measured over both depth and time through the current quarter. As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any time. Compare bounding plume to current plume on Figure 6.

3. The Sr-90 bounding isopleth encompasses upper bound values measured over both depth and time through the current quarter. As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any time. Compare bounding plume to current plume on Figure 7.

4. Two discrete isopleths have been drawn around MW-39 and 41 given measured Sr90 concentrations greater than 2 pCi/L. It is expected that similar concentrations exist at other locations along the legacy piping alignment in addition to the locations shown.

5. Historically elevated Tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Data trends through Q1 2010 indicate that the observed Tritium peaks in MW-42-49 and downgrading wells associated with this release have dissipated through the groundwater flow system.

6. Elevated tritium levels in MW-45-42 are consistent with with a surficial release to Unit 3 Manhole A2. This release was initially detected in a storm drain sample taken 03/25/2009 under the 80-10 Effluents Program.

7. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a November 21, 2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

1. Average Tritium isopleths and activity values are yearly rolling arithmetic averages of the current and preceeding three quarters' data. Only values greater than the MDC are used in this average, thus adding a degree of conservatism to the subsequent dose computations.

2. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%)

interstitial space (i.e. fractures).

3. Storm or foundation drain sampling locations, for which investigation levels are not applicable.

4. Historically elevated Tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Data trends through Q1 2010 indicate that the observed Tritium peaks in MW-42-49 and downgrading wells associated with this release have dissipated through the groundwater flow system.

5. Historically elevated Tritium levels in MW-45-42 observed during Q2 2009 were consistent with with a surficial release to Unit 3 Manhole A2. This release was initially detected in a storm drain sample taken 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter.

6. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a Q4 2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have Notes:

1. Groundwater contours drawn from Q4 2008 groundwater data to show groundwater conditions used for recalibration of the Precipitation Mass Balance Model (see Q2 2009 LTM Report). These contours developed from limited data recorded on 11/11/2008. Actual elevations may vary from conditions shown and the actual distribution of piezometric heads is likely more complex than indicated.

4) Q1 2010 analytical results for MW-66-21 and MW-66-36 were interchanged to correct a sample misidentification after inspecting the data trends in both sampling ports (both historic and for Q2 2010).

1) Only results greater than the MDC are reported herein. ND therefore indicates that the analytical result was below the MDC and typically also below the standard deviation threshold of three times 1 sigma. The rolling average is calculated using only results greater than the MDC. Given that ND represents real groundwater sampling results where the radionuclide activity level is either positive but very low and unquantifiable, or not detectable above background, its exclusion results in a high bias to the average and thus adds a measure of conservatism to the subsequent dose

2) A shaded value indicates that the reported activity exceeds the Investigation Level (I.L.) that was applicable at the time of sampling. NA indicates that data is not available for this time period.

3)

Indicates storm or foundation drain sampling locations, for which investigation levels are not applicable.

These contours developed from limited data recorded on 11/11/2008. Actual elevations may vary from conditions shown and the actual distribution of piezometric heads is likely more complex than indicated.

Data Notes:

1. Quarterly Tritium isopleths and activity values are yearly rolling arithmetic averages of the current and preceeding three quarters' data. Only values greater than the MDC are used in this average, thus adding a degree of conservatism to the subsequent dose computations.

2. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%) interstitial space (i.e. fractures).

3. Storm or foundation drain sampling locations, for which investigation levels are not applicable.

4. Historically elevated Tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Data trends through Q1 2010 indicate that the observed Tritium peaks in MW-42-49 and downgrading wells associated with this release have dissipated through the groundwater flow system.

5. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a November 21,2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

1. Average Sr-90 isopleths and activity values are yearly rolling arithmetic averages of the current and preceeding three quarters' data. Only values greater than the MDC are used in this average, thus adding a degree of conservatism to the subsequent dose computations.

2. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%)

interstitial space (i.e. fractures).

3. Storm or foundation drain sampling locations, for which investigation levels are not applicable.

4. Two discrete isopleths have been drawn around MW-39 and MW-41 given average concentrations greater than 2 pCi/L. It is expected that similar concentrations exist at other locations along the legacy piping alignment in addition to the locations shown.

5. Sr-90 activity at MW-111 may be due to desorption of residual Sr-90 from backfill used in the Transformer Yard.

6. Historically elevated Tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Data trends through Q1 2010 indicate that the observed Tritium peaks in MW-42-49 and downgrading wells associated with this release have dissipated through the groundwater flow system.

7. Historically elevated Tritium levels in MW-45-42 observed during Q2 2009 were consistent with with a surficial release to Unit 3 Manhole A2. This release was initially detected in a storm drain sample taken 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter.

8. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a 11/21/2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

Investigation Level Rolling Annual Average Investigation Level

4) Q1 2010 analytical results for MW-66-21 and MW-66-36 were interchanged to correct a sample misidentification after inspecting the data trends in both sampling ports (both historic and for Q2 2010).

1) Only results greater than the MDC are reported herein. ND therefore indicates that the analytical result was below the MDC and typically also below the standard deviation threshold of three times 1 sigma. The rolling average is calculated using only results greater than the MDC. Given that ND represents real groundwater sampling results where the radionuclide activity level is either positive but very low and unquantifiable, or not detectable above background, its exclusion results in a high bias to the average and thus adds a measure of conservatism to the subsequent dose computations.

2) A shaded value indicates that the reported activity exceeds the Investigation Level (I.L.) that was applicable at the time of sampling. NA indicates that data is not available for this time period.

3)

Indicates storm or foundation drain sampling locations, for which investigation levels are not applicable.

4) Q1 2010 analytical results for MW-66-21 and MW-66-36 were interchanged to correct a sample misidentification after inspecting the data trends in both sampling ports (both historic and for Q2 2010).

Rolling Annual Average

1) Only results greater than the MDC are reported herein. ND therefore indicates that the analytical result was below the MDC and typically also below the standard deviation threshold of three times 1 sigma. The rolling average is calculated using only results greater than the MDC. Given that ND represents real groundwater sampling results where the radionuclide activity level is either positive but very low and unquantifiable, or not detectable above background, its exclusion results in a high bias to the average and thus adds a measure of conservatism to the subsequent dose computations.

2) A shaded value indicates that the reported activity exceeds the Investigation Level (I.L.) that was applicable at the time of sampling. NA indicates that data is not available for this time period.

3)

Indicates storm or foundation drain sampling locations, for which investigation levels are not applicable.

shaded value shaded value Notes:

1. Groundwater contours drawn from Q4 2008 groundwater data to show groundwater conditions used for recalibration of the Precipitation Mass Balance Model (see Q2 2009 LTM Report). These contours developed from limited data recorded on 11/11/2008. Actual elevations may vary from conditions shown and the actual distribution of piezometric heads is likely more complex than indicated.

Data Notes:

1. Average Cesium, Cobalt, and Nickel activity values are yearly rolling arithmetic averages of the current and preceeding three quarters' data. Only values greater than the MDC are used in this average, thus adding a degree of conservatism to the subsequent dose computations.

2. Storm or foundation drain sampling locations, for which investigation levels are not applicable.

3. Historically elevated Tritium levels in MW-42-49 obsrved during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Elevated tritium levels not seen in MW-53; therefore, this transient leakage was likely to have been generally confined to, and contained by, the Unit 1 North Curtain Drain.

4. Historically elevated Tritium levels in MW-45-42 observed during Q2 2009 were consistent with with a surficial release to Unit 3 Manhole A2. This release was initially detected in a storm drain sample taken 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter.

5. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a November 21, 2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

FINAL QUARTERLY LONG-TERM GROUNDWATER MONITORING REPORT Q2 2010 (REPORT NO. 10)

APPENDIX A: LIMITATIONS

HYDROGEOLOGICAL LIMITATIONS 1.

The conclusions and recommendations submitted in this report are based in part upon the radiological, chemical and physical data from water analyses. These data were obtained from specific sampling locations at specific times. The full nature and extent of variations in the data between these specific locations and times are not known. The conditions existing between these specific locations and times have only been inferred using interpolation and extrapolation based on judgment.

2.

The subsurface profiles described in the text and presented in the report figures are intended to convey anticipated trends in subsurface conditions. The conditions shown are approximate and generalized and were developed, in part, based on judgment. For specific information at specific locations, refer to the individual subsurface investigation logs.

3.

Water level readings (piezometric pressures) have been made in the specific borings, monitoring wells, and Waterloo installations at times and under conditions stated. These data have been reviewed and interpretations have been made in the text and on the figures of this report. However, it must be noted that temporal and spatial fluctuations in the level of the groundwater may occur due to variations in rainfall and other factors different from those prevailing at the time and location measurements were made.

4.

Where quantitative laboratory testing has been conducted by an outside laboratory, GZA has relied upon the validity of the data provided, and has not conducted an independent laboratory evaluation of the reliability of these data.

5.

Radiological and chemical analyses have been performed for specific parameters during the course of this study, as summarized in the text. Additional constituents not searched for may be present in soil and groundwater at the site.

6.

Variations in the types and concentrations of contaminants and variations in their flow paths may occur due to seasonal water table fluctuations, past and current plant operational practices, the passage of time, and other factors. Should additional data (water analyses, water elevations, subsurface deposits, plant construction and operation, etc.) become available in the future, these data should be reviewed by GZA, and the conclusions and recommendations presented herein modified accordingly.

7.

This monitoring report was developed by GZA GeoEnvironmental Inc for the exclusive of Entergy Nuclear Northeast (Entergy) at the Indian Point Energy Center. Any use of data or information provided in the report, by parties other than Entergy, is prohibitated without the prior written permission of Entergy and GZA.
