1.0 INTRODUCTION
This report summarizes and interprets results of the Radiological Environmental Monitoring Program (REMP) conducted by Environmental, Inc., Midwest Laboratory for the Monticello Nuclear Generating Plant, Monticello, Minnesota, during the period January - December, 2013.
This Program monitors the levels of radioactivity in the air, terrestrial, and aquatic ehvironments in order to assess the impact of the Plant on its surroundings.
Tabulations of the individual analyses made during the year are not included in this report. These data are included in a reference document (Environmental, Inc., Midwest Laboratory, 2014a) available at the Monticello Nuclear Generating Plant, Chemistry and Radiation Protection Department.
The Monticello Nuclear Generating Plant is a boiling water reactor with a nominal generating capacity of 600 MWe. It is located on the Mississippi River in Wright County, Minnesota, owned by Xcel Energy Corporation and operated by Northern States Power Co.-Minnesota. Initial criticality was achieved on December 10, 1970. Full power was achieved March 5, 1971 and commercial operation began on June 30, 1971.

SUMMARY
The Radiological Environmental Monitoring Program (REMP) required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications and the Offsite Dose Calculation Manual (ODCM) for the Monticello Nuclear Generating Plant is described. Results for the year 2013 are summarized and discussed.
Program findings show background levels of radioactivity in the environmental samples collected in the vicinity of the Monticello Nuclear Generating Plant.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP) 3.1 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program (REMP) at the Monticello Nuclear Generating Plant is to assess the impact of the Plant on its environment. For this purpose, samples are collected from the air, terrestrial, and aquatic environments and analyzed for radioactive content. In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLD's).
Sources of environmental radiation include the following:
(1) Natural background radiation arising from cosmic rays and primordial radionuclides; (2) Fallout from atmospheric nuclear detonations; (3) Releases from nuclear power plants; (4) Industrial and medical radioactive waste; and (5) Fallout from nuclear accidents.
In interpreting the data, effects due to the Plant must be distinguished from those due to other sources.
A major interpretive aid in assessment of these effects is the design of the monitoring program at the Monticello Plant which is based on the indicator-control concept. Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A plant effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
An additional interpretive technique involves analyses for specific radionuclides present in environmental samples collected from the Plant site. The Plant's monitoring program includes analyses for tritium and iodine-131. Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified: zirconium-95, cesium-137, cerium-144, beryllium-7, and potassium-40. The first three gamma-emitting isotopes were selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation.
Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products 10 days after reactor shutdown. On the other hand, 10 days after a nuclear explosion, the contributions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud, 1963). Beryllium-7 is of cosmogenic origin and potassium-40 is a naturally-occurring isotope. They were chosen as calibration monitors and should not be considered as radiological impact indicators. The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and cerium-141. These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the final group, manganese-54, iron-59, cobalt-58 and -60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of a nuclear power plant's effluents, but are not produced in significant quantities by nuclear detonations.
Other means of distinguishing sources of environmental radiation are employed in interpreting the data. Current radiation levels are compared with previous levels, including those measured before the plant became operational. Results of the Plant's Monitoring Program can be related to those obtained in other parts of the world. Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.

3.2 Pro-gram Description The sampling and analysis schedule for the Radiological Environmental Monitoring Program (REMP) at the Monticello Plant is summarized in Table 5.1 and briefly reviewed below. Table 5.2 defines the sampling location codes used in Table 5.1 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the plant site. To assure that sampling is carried out in a reproducible manner, detailed sampling procedures have been prescribed (Monticello Generating Plant REMP Surveillances, Current Revision). Maps of sampling locations are included in Appendix D.
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at five locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at all of these locations. Filters are changed and counted weekly.
Particulate filters are analyzed for gross beta activity and charcoal filters for iodine-131. Quarterly composites of particulate filters from each location are determined by gamma spectroscopy. One of the five locations is a control (M-1), and four are indicators (M-2, M-3, M-4, M-5). One of the indicators is located in the geographical sector expected to be most susceptible to any atmospheric emissions from the Plant (highest D/Q sector).
Ambient gamma radiation is monitored at forty locations, using CaSO4 :Dy dosimeters with four sensitive areas at each location: fourteen in an inner ring in the general area of the site boundary, sixteen in the outer ring within 4-5 mile radius, six at special interest locations and four control locations, outside a 10 mile radius from the plant. They are replaced and measured quarterly.
As substitute for dairy sampling, pasture grass and vegetation are collected from locations M-41, M-42 and M-43 (C). The samples are analyzed for iodine-1 31 and other gamma emitting isotopes.
Vegetables, corn and potatoes are collected annually if fields are irrigated by water in which liquid radioactive effluent has been discharged. Analysis is done for gamma-emitting isotopes.
Ground water is monitored by quarterly collections from three off-site locations (one control and two indicators) and one on-site Plant well. To prevent possible groundwater contamination due to plant operations, samples from nineteen on-site monitoring wells are collected and analyzed for tritium and gamma emitting isotopes. The Ground Water Monitoring Program is further described in Appendix E.
Quarterly collections of storm water runoff were added to monitor another possible pathway to the groundwater aquifer. The samples are also analyzed for tritium and gamma emitting isotopes.
River water is collected weekly at two locations, one upstream of the plant and one downstream.
Monthly composites are analyzed for gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
Drinking water is collected weekly from the City of Minneapolis water supply, which is taken from the Mississippi River downstream of the Plant. Monthly composites are analyzed for gross beta, iodine-1 31, and gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
The aquatic environment is also monitored by semi-annual upstream and downstream collections of fish, invertebrates, and shoreline sediments. Shoreline sediment is also collected from one downstream recreational location. All samples are analyzed for gamma-emitting isotopes.

3.3 Pro-gram Execution The Program was executed as described in the preceding section with the following exceptions:
(1) Air Particulates / Air Iodine:
M-01, No air particulate / air iodine sample was available for the week ending January 16, 2013, the sampler failed due to a faulty toggle switch.
M-01, A partial air particulate / air iodine sample (54 M 3) was collected for the week ending May 1, 2013, due to sampler failure. No air particulate / air iodine sample was available for the week ending May 8, 2013, due to sampler failure. The vacuum pump was replaced.
M-02, No air particulate sample was collected for the week ending November 27, 2013, the filter was misaligned in the holder.
(2) Surface Water:
Surface water was not collected at location M-08 for the months of January, February, March and December, 2013, due to unsafe ice conditions.
(3) Well Water:
Well water was not collected at location MW-27 in January, 2013. No water was available from the outside tap.
(4) Drinking Water (M-14):
No sample was available for the January 13, 2013 collection. The sample was damaged in shipment. The drinking water sample for May 7, 2013 was lost during shipping.
No drinking water sample was available November 18, 2013. The sample was missed.
(5) Milk There was no goat milk available from locations M-16 and M-17 in 2013. Goats are no longer milked at location M-16, the herd has been sold.
Deviations from the program are summarized in Table 5.3.
3.4 Program Modifications Milk sampling was dropped from the REMP in 2013. The indicator location M-16 discontinued dairy operations.
Modifications to the Groundwater monitoring program are detailed in Appendix E.

3.5 Laboratory Procedures The iodine-131 analyses in milk and drinking water were made using a sensitive radiochemical procedure which involves separation of the iodine using an ion-exchange method and solvent extraction and subsequent beta counting.
Gamma-spectroscopic analyses are performed using high-purity germanium (HPGe) detectors.
Levels of iodine-131 in cabbage and natural vegetation and concentrations of airborne iodine-1 31 in charcoal samples were determined by gamma spectroscopy.
Tritium concentrations are determined by liquid scintillation.
Analytical Procedures used by Environmental, Inc. are on file and are available for inspection.
Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28, 1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1984.
Environmental, Inc., Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained. Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2012). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs. Results obtained in the crosscheck programs are presented in Appendix A.
3.6 Land Use Census In accordance with the MNGP Chemistry Manual, Procedure 1.05.41, "Annual Land Use Census and Critical Receptor Identification", a land use census shall be conducted and shall identify the location of the nearest milk animal, the nearest residence, and the nearest garden of greater than 500 ft 2 producing fresh leafy vegetables, in each of the 16 meteorological sectors within a distance of 5 miles. The census shall also identify the locations of all milk animals and all 500 ft 2 or greater gardens producing broad leaf vegetation in each of the meteorological sectors within a distance of three miles. This census shall be conducted at least once per year between the dates of May 1 and October 31. New locations shall be added to the radiation environmental monitoring program within 30 days and sampling locations having lower calculated doses or a lower dose commitment may be deleted from this monitoring program after October 31 of the year in which the land use census was conducted.
The 2013 land use census was conducted between September 10 and September 16, 2013.
Closer gardens were identified in the E and S sectors, resulting in revised D/Q values greater than 20%. Improved GPS software resulted in slight changes to sector assignments. The highest D/Q value for nearest garden was calculated in the SE sector. The highest D/Q location for nearest resident did not change from the 2012 census. There were no milk animals found within a five mile radius of the plant. The goat milk farm in the SSE sector has sold off the herd.
A new site for critical receptor was identified in the 2013 census, located in the SE sector, 1.1 miles from the plant. The Offsite Dose Calculation Manual (ODCM) will be revised to reflect the changes.
Details of the land use census are contained in the Land Use Census and Critical Receptor Report, Monticello Nuclear Generating Plant, Chemistry and Radiation Protection Department.

4.0 RESULTS AND DISCUSSION All of the scheduled collections and analyses were made except those listed in Table 5.3.
All results are summarized in Table 5.4 in a format recommended by the Nuclear Regulatory Commission in Regulatory Guide 4.8. For each type of analysis of each sampled medium, this table lists the mean and range for all indicator locations and for all control locations. The locations with. the highest mean and range are also shown.
4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 2013. The Fukushima Daiichi nuclear accident occurred March 11, 2011.
There were no reported atmospheric nuclear tests in 2013. The last reported test was conducted on October 16, 1980 by the People's Republic of China.
4.2 Summary of Preoperational Data The following constitutes a summary of preoperational studies conducted at the Monticello Nuclear Generating Plant during the years 1968 to 1970, to determine background levels expected in the environment, and provided, where applicable, as a means for comparison with present day levels. Strict comparisons, however, are difficult to make, since background levels of radiation were much higher in these years due to radioactive fallout from the atmosphere. Gross beta measurements in fallout averaged 20,600 pCi/m 3 in 1969 and 12,000 pCi/m 3 in 1970. These levels are reflected throughout the various media tested.
In the air environment, ambient gamma radiation (TLDs) averaged 9.1 mRem/4 weeks during preoperational studies (1970). Gross beta in air particulates in 1969 and 1970 averaged 0.20 pCi/m 3. Present day levels have stabilized at around 0.025 pCi/m 3. Airborne radioiodine remained below detection levels.m 3 In the terrestrial environment of 1968 to 1970, milk, agricultural crops, and soil were monitored. In milk samples, low levels of Cs-1 37 and Sr-90 were detected. Cs-137 levels averaged 16.7 pCi/L.
Soybean crop measurements in 1969 averaged 35.5 pCi/g for gross beta and 0.3 pCi/g for Cs-137. Gross beta measured in soil averaged 51.7 pCi/g . Present day measurements for cesium-137 are below detection levels in milk and agricultural crops.
The aqueous environment was monitored by testing of river water, bottom sediments, fish, aquatic vegetation, and periphyton. Specific location comparison of drinking, river, and well water concentrations for tritium and gross beta are not possible. However, tritium background levels, measured at seven separate locations from 1968 to 1970, averaged 970 pCi/L. Present day environmental samples measure below detection levels. Values for gross beta, measured from 1968 to 1970, averaged 9.8 pCi/L in upstream and downstream Mississippi River water, 4.4 pCi/L for well waters, and 18.6 pCi/L for lake waters. Gamma emitters were below the lower limit of detection (LLD). In shoreline sediments, gross beta background levels in 1970 averaged 49.8 pCi/g for both upstream and downstream samples. Cs-137 activity averaged 0.10 pCi/g for both upstream and downstream samples. Low levels of Cs-137, occasionally observed today can still be attributed to residual activity from atmospheric fallout. Gross beta levels in fish flesh averaged 5.3 pCi/g in 1968 and 1969. Cs-137, measured in 1969 and 1970, averaged 0.044 pCi/g. Gross beta background levels, in 1970, for aquatic vegetation, algae, and periphyton samples measured 86.7 pCi/g, 76.5 pCi/g, and 28.1 pCi/g respectively.

4.3 Program Findings Results obtained show background levels of radioactivity in environmental samples collected outside of the Site Protected Area in 2013. The trace levels of strontium-90 and cesium-137, still measurable in soil and sediment samples, are generally attributed to deposition of fallout from previous decades.
Tritium was identified in some groundwater samples collected within the site Protected Area.
Ambient Radiation (TLD's)
Ambient radiation was measured in the general area of the site boundary, at an outer ring 4 - 5 mi.
distant from the Plant, at special interest areas and at four control locations. The means were similar for both inner and outer rings (14.4 and 14.0 mRem/91 days, respectively). The mean for special interest locations was 14.0 mRem/91 days and the mean for the control locations was 15.5 mRem/91 days. Dose rates measured at the inner and outer ring locations were similar to those observed from 1998 through 2012 and are tabulated below. No plant effect on ambient gamma radiation is indicated (Figure 5-1).

Typically, the highest average readings occur during the months of January and December, and the first and fourth quarters, as observed in 1998 through 2013.
Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation (Arnold and AI-Salih, 1955) was detected in all samples, with an average activity of 0.065 pCi/im3 for all locations. All other gamma-emitting isotopes were below their respective LLD limits.
Airborne Iodine 3
Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.03 pCi/m in all samples.
9
River Water and Drinking Water Tritium activity measured below 500 pCi/L in all samples. Gross beta activity in Minneapolis drinking water averaged 2.6 pCi/L and was similar to average levels observed from 1998 through 2012. Gross beta averages are tabulated below.

Comparisons with data reported by the USEPA for Minneapolis drinking water samples collected from 1980 through 2005 indicate that concentrations of these nuclides are remaining fairly constant. Gamma-emitting isotopes were below detection limits in all surface water samples.
There was no indication of a plant effect.
Well Water At the four indicator and control locations, tritium measured below 500 pCi/L for all samples.
Gamma isotopic results were below detection limits.
The data for 2013 were consistent with previous years results and no plant operational effects were indicated.
Pasture Grass Pasture grass was collected in July, August and September, 2013. Iodine-131 concentrations measured below 0.034 pCi/g wet weight in all samples. With the exceptions of naturally-occurring beryllium-7 and potassium-40, no other gamma-emitting isotopes were detected.
Crops A vegetation collection was not required for 2013. No crops, within five miles of the plant, were found using irrigation water from the Mississippi River.
10
Fish Fish were collected in May and September. Flesh was separated from the bones and analyzed by gamma spectroscopy. Only naturally-occurring potassium-40 was found in the upstream and downstream samples (3.27 and 3.19 pCi/g wet weight, respectively). Other gamma-emitting isotopes remained below detection limits. There was no indication of a plant effect.
Invertebrates Samples were collected in August and October, 2013, and analyzed by gamma spectroscopy. All gamma-emitting isotopes, with the exception of naturally-occurring potassium-40 were below detection limits. There was no indication of any plant effect.
Shoreline Sediments Upstream, downstream and downstream recreational area shoreline sediment collections were made in August and October, 2013, and analyzed for gamma-emitting isotopes. Low levels of cesium-137 were detected in two downstream samples (M-15), at an average concentration of 0.0035 pCi/g dry weight. Similar levels of activity and distribution have been observed since 1978, and are indicative of the influence of fallout deposition. Naturally-occurring beryllium-7 and potassium-40 were also detected. There was no indication of a plant effect.
Ground Water Monitoring Program Monitoring Wells (on-site)
Measurable tritium above 500 pCi/L was detected in 11 of 114 samples collected from the nineteen on-site monitoring wells. The activities ranged from 566 to 15,124 pCi/L, similar or slightly higher than concentrations seen in 2011 and 2012. The highest activities were observed at well MW-09A.
Gamma isotopic measurements were below detection limits.
Stormwater Run-off (on-site)
No tritium was detected in any of the four stormwater runoff samples submitted for analysis in 2013. Gamma isotopic analysis results measured below detection limits.

January through December, 2013
Appendix A Interlaboratory Comparison Proqram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuingagency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.
Table A-2 lists results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.
Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.
Table A-5 lists REMP specific analytical results from the in-house "duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Complete analytical data for duplicate analyses is available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
Results in Table A-7 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).
Attachment A lists the laboratory precision at the 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.
Out-of-limit results are explained directly below the result.

APPENDIX B. DATA REPORTING CONVENTIONS Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.
1.0. Single Measurements Each single measurement is reported as follows: x+/- s where: x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is less than the lower limit of detection L, it is reported as: < L, where L = the lower limit of detection based on 4.66a uncertainty for a background sample.
3.0. Duplicate analyses If duplicate analyses are reported, the convention is as follows.
3.1 Individual results: For two analysis results; x1 +/- si and x2 +/- s 2 Reported result: x +/- s; where x = (1/2) (x1 + x2) and s = (1/2) + s+
3.2. Individual results: < L1 , < L2 Reported result: < L, where L = lower of Li and L2 3.3. Individual results: x +/- s, < L Reported result: x +/- s if x > L; < L otherwise.
4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation "s" of a set of n numbers xi, x2 ... xn are defined as follows:
- 1 x-)
x=n I-x s= n-4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.
4.5 In rounding off, the following rules are followed:
4.5.1. If the number following those to be retained is less than 5, the number is dropped, and the retained numbers are kept unchanged. As an example, 11.443 is rounded off to 11.44.
4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.

APPENDIX E Ground Water Monitorinq Well Samples
1.0 INTRODUCTION
This appendix to the Radiological Environmental Monitoring Program Annual Report to the United States Nuclear Regulatory Commission summarizes and interprets results of the Ground Water Monitoring Program samples taken at the Monticello Nuclear Plant, Monticello, Minnesota, during the period January
- December 2013. This sampling program was established in October of 2006 following the industry initiative on ground water monitoring.
Complete data tables for each period and sampling location, are provided in a reference document, (Environmental, Inc., Midwest Laboratory, "Complete Analyses Data Tables, January - December, 2013")
available at the Monticello Nuclear Generating Plant, Chemistry and Radiation Protection Department.

SUMMARY
The Ground Water Sampling Program was established following industry events where tritium was discovered in ground water surrounding commercial nuclear facilities. This program is described and the results for 2013 are summarized and discussed.
Program findings for 2013 detected low levels of tritium in monitoring wells located on the plant property.
With the exception of monitoring wells MW-9A and MW-1 3A, tritium measured at or near expected natural background levels. No tritium was detected in four samples of storm water runoff samples collected from the sanitary sewer and the sewer lift station. The 2013 sample results (excluding MW-9A and MW-13A) all measured below the required limit of 500 pCi/L. Measurements for 2013 were below the Environmental Protection Agency's drinking water standard of 20,000 pCi/L and present no harm to members of the public.
None of the samples monitored for gamma-emitting isotopes showed activity greater than the LLD.
A summation of the analytical data for both ground water monitoring wells and storm water runoff samples is provided in Table E-3.

3.0 Ground Water Sampling Program 3.1 Program Design and Data Interpretation The purpose of this sampling program is to assess the impact of any tritium leaching into the environment (ground water system) from MNGP. For this purpose, water samples are collected and analyzed for tritium content.
3.2 Program Description The sampling and analysis schedule for the Ground Water Monitoring Program is summarized in Table E-1 and briefly reviewed below. Table E-2 defines the additional sample locations and codes for the Ground Water Sampling Program.
Sampling from the groundwater monitoring wells was conducted monthly at fourteen locations and quarterly for five locations.
3.3 Program Execution The Program was executed as described with the following exceptions:
Additional analyses for gamma emitting isotopes were performed on samples from each of the nineteen monitoring wells. The results are summarized in Table E-3. Results of individual analyses are reported in Tables E-4 and E-5.
3.4 Pro-gram Modifications There were no additional on-site monitoring wells added to the ground water program in 2013.

3.5 Results and Discussions Sampling points in North America have shown tritium concentrations in precipitation may range from 5 pCi/L to 157 pCi/L (Environmental Isotope Data No. 10; World Survey of Isotope Concentration in Precipitation (1988-1991). Results obtained show tritium in ground water samples at or near expected natural background levels, with the exception of monitoring wells, MW-9A and MW-1 3A.
Excluding the data from wells MW-9A and MW-13A, 2013 sample results all measured below an LLD level of 500 pCi/L, and were similar to averages measured in 2012.
The tritium activity at location MW-9A was higher than previous measurements from 2010 to 2012. A spike in activity seemed to occur from July through September, 2013, but declined significantly in October, and dropped throughout the rest of the year. Activity ranged from a high of 15,124 to less than 500 pCi/L. Previous investigations have concluded the activity may be due to a 1981 spill from the Condensate Storage Tanks that had infiltrated the surface and migrated towards MW-9.
One sample collected from MW-9A was tested for hard to detect isotopes. Results for gross alpha, iron-55, nickel-63 and strontium-89 and strontium-90 all measured below detection limits.
1,The tritium activity measured in samples collected from monitoring well MW-13A was highest in October and November, 2013, suggesting migration from MW-9A. Activity ranged from a high of 729 to less than 500 pCi/L.
None of the groundwater samples analyzed for gamma-emitting isotopes showed activity greater than LLD.

b LLD = nominal lower limit of detection based on a 4.66 sigma counting error for background sample.
c Mean and range are based on detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses (F).
d Locations are specified: (1) by name, and/or station code and (2) by distance (miles) and direction relative to reactor site.
Non-routine results are those which exceed ten times the control station value. If no control station value is available, the result is considered non-routine if it exceeds ten time the typical preoperational value for the medium or location.
