Transient Spill from Temporary R.O. Skid Piping -

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 an increased activity observed in Unit 3 Manhole A2. This release was initially detected in a storm drain sample collected 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter. Additionally, transient Tritium peaks have been recently detected in MH-A2 from Q3 2010 to Q1 2011. These increases are consistent with elevated Tritium levels in MW-41-40, MW-46 and B-1. Based on investigations initiated in, and ongoing since, 2009 and the more recent sampling of the Unit 3 Fuel Storage Building (FSB) roof drains, it has been concluded that these increases in storm drain and monitoring well Tritium activity are due to condensation of SFP evaporation on the FSB roof (Washout) when the exhaust fan is not operating, which then enters the roof drains and discharges directly into MH-A2 during rainfall events.

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.

Rolling Annual Average

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.

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.

3)

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

Rolling Annual Average

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.

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.

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 an increased activity observed in Unit 3 Manhole A2. This release was initially detected in a storm drain sample collected 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter. Additionally, transient Tritium peaks have been recently detected in MH-A2 from Q3 2010 to Q2 2011. These increases are consistent with elevated Tritium levels in MW-41-40, MW-46 and B-1. Based on investigations initiated in, and ongoing since, 2009 and the more recent sampling of the Unit 3 Fuel Storage Building (FSB) roof drains, it has been concluded that these increases in storm drain and monitoring well Tritium activity are due to condensation of SFP evaporation on the FSB roof (Washout) when the exhaust fan is not operating, which then enters the roof drains and discharges directly into MH-A2 during rainfall events.

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.

6. Elevated levels of Tritium initially detected in U1-CSS, MW-39, MW-46, MW-54, MW-56 and MW-57 during the Q2-2011 sampling event appear to have originated from a Q2 2011 sample sink overflow and subsequent floor flooding in a Unit 1 Chemical Systems Building sample room on the 53 elevation.

Rolling Annual Average Well ID

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.

Investigation Level

5) *** The Q1 2011 MW-40-100, MW-40-127 and MW-51-189 Cs-137 results were verified by re-analysis. However, based on the available chemistry and Site hydrogeologic data, these values do not appear to be representative of the groundwater conditions at these sampling intervals.

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

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.

4) ** Indicates 2011 I.L. not computed for this well due to absence of 2010 data.

Transient Spill from Temporary R.O. Skid Piping -

Entered MW-32 Vault and MH 11/21/2009 5

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 an increased activity observed in Unit 3 Manhole A2. This release was initially detected in a storm drain sample collected 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter. Additionally, transient Tritium peaks have been recently detected in MH-A2 from Q3 2010 to Q3 2011. These increases are consistent with elevated Tritium levels in MW-41-40, MW-46 and B-1. Based on investigations initiated in, and ongoing since, 2009 and the more recent sampling of the Unit 3 Fuel Storage Building (FSB) roof drains, it has been concluded that these increases in storm drain and monitoring well Tritium activity are due to condensation of SFP evaporation on the FSB roof (Washout) when the exhaust fan is not operating, which then enters the roof drains and discharges directly into MH-A2 during rainfall events. As such, Entergy placed the FSB vent fan back in service on 7-21-2011 and the Tritium activity returned to baseline conditions within 2 weeks.

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.

6. Elevated levels of Tritium initially detected in U1-CSS, MW-39, MW-46, MW-54, MW-56 and MW-57 during the Q2-2011 sampling event appear to have originated from a Q2 2011 sample sink overflow and subsequent floor flooding in a Unit 1 Chemical Systems Building sample room on the 53 elevation.

6) **** Four Post-Q2 2011 MH-5 VCFD samples were collected. All four samples were ND for Cs-137.

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) ** Indicates 2011 I.L. not computed for this well due to absence of 2010 data.

Cesium Results (pCi/L)

Rolling Annual Average Well ID

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.

Investigation Level

5) *** The Q1 2011 MW-40-100, MW-40-127 and MW-51-189 Cs-137 results were verified by re-analysis. However, based on the available chemistry and Site hydrogeologic data, these values do not appear to be representative of the groundwater conditions at these sampling intervals.

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.

4) ** Indicates 2011 I.L. not computed for this well due to absence of 2010 data.

Transient Spill from Temporary R.O. Skid Piping -

Entered MW-32 Vault and MH 11/21/2009 5

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 an increased activity observed in Unit 3 Manhole A2. This release was initially detected in a storm drain sample collected 03/25/2009 under the 80-10 Effluents Program. This Tritium peak dissipated prior to samples taken during the subsequent quarter. Additionally, transient Tritium peaks have been recently detected in MH-A2 from Q3 2010 to Q3 2011. These increases are consistent with elevated Tritium levels in MW-41-40, MW-46 and B-1. Based on investigations initiated in, and ongoing since, 2009 and the more recent sampling of the Unit 3 Fuel Storage Building (FSB) roof drains, it has been concluded that these increases in storm drain and monitoring well Tritium activity are due to condensation of SFP evaporation on the FSB roof (Washout) when the exhaust fan is not operating, which then enters the roof drains and discharges directly into MH-A2 during rainfall events. As such, Entergy placed the FSB vent fan back in service on 7-21-2011 and the Tritium activity in MH-A2 returned to baseline conditions within 2 weeks.

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.

6. Elevated levels of Tritium initially detected in U1-CSS, MW-39, MW-46, MW-54, MW-56 and MW-57 during the Q2-2011 sampling event appear to have originated from a Q2 2011 sample sink overflow and subsequent floor flooding in a Unit 1 Chemical Systems Building sample room on the 53 elevation.

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.

Investigation Level

5) *** The Q1 2011 MW-40-100, MW-40-127 and MW-51-189 Cs-137 results were verified by re-analysis. However, based on the available chemistry and Site hydrogeologic data, these values do not appear to be representative of the groundwater conditions at these sampling intervals.

FINAL QUARTERLY LONG-TERM GROUNDWATER MONITORING REPORT Q1 THROUGH Q4 2011 (REPORT NO. 13)

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.
