SUMMARY

Plant-related activation, corrosion or fission products were not detected during 2007 in airborne particulate and radioiodine filters, ground water, drinking water, shoreline sediment, broadleaf vegetation, crops, terrestrial vegetation, aquatic vegetation, or soil samples.

Activation, corrosion or fission products attributable to plant operation were detected during 2007 in surface water, fish, and bottom sediment samples.

Nuclides detected in Radiological Environmental Monitoring Program (REMP) samples were below applicable NRC reporting levels.

Based upon the radiological environmental monitoring results, it was concluded that station operations had no significant radiological impact on the health and safety of the public or the environment.

INTRODUCTION The 2007 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 through December 31, 2007.

WCGS is located in Coffey County, Kansas, approximately five miles northeast of Burlington, Kansas.

Fuel loading commenced at WCGS on March 12, 1985. The operational phase of the REMP began with initial criticality on May 22, 1985, and the first detectable quantities of radioactivity were reported in plant effluents in June 1985.

This report contains a description of the REMP conducted by Wolf Creek Nuclear Operating Corporation (WCNOC), a discussion of monitoring program results, the revisions or changes to the program, program deviations, the Interlaboratory Comparison Program and a comparison to the Radioactive Effluents Release Program. The Interlaboratory Comparison Program results, a summary of results in the Nuclear Regulatory Commission (NRC) Branch Technical Position specified format, the individual sample results and the Land Use Census Report are included as appendices.

I. PROGRAM DESCRIPTION Radiological environmental samples were collected according to the schedule in WCGS procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program). Environmental samples were collected by the WCGS Environmental Management group and were analyzed by Environmental, Inc.

Detroit Edison processed environmental thermoluminescent dosimeters (TLDs) at the Enrico Fermi 2 plant. Table 1 lists sampling pathways and frequencies of sampling and analysis.

Table 2 lists each sample location's distance and direction from the plant. Samples in addition to those required by the WCGS Offsite Dose Calculation Manual (ODCM) were also obtained and analyzed.

The following is a description of the sampling and analysis program by individual pathways.

2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Pagel of30

A. Airborne Pathway Low volume air sampling pumps collected particulate and radioiodine samples on 47 mm glass fiber filters and charcoal canisters, respectively.

The filters and charcoal canisters were changed out weekly, labeled, and shipped to Environmental, Inc. for analysis. During February of 2007, air samplers with digital flow meters were installed. These air sample units digitally display the total time, total volume and flow rate.

Gross beta analysis of the air particulate samples was performed after a nominal 72-hour period to allow the radon and thoron daughter products to decay.

Weekly air particulate filters were combined into quarterly composites for each location and analyzed for gamma emitting isotopes.

Charcoal canisters were routinely counted in groups of five to determine the presence or absence of 1-131. Positive indication of 1-131 would have resulted in analysis of each individual charcoal canister.

Air samples were collected from six locations. Indicator locations 2, 37 and 49 are located in the three sectors with the highest ground level deposition constants (D/Q).

Air sampling stations are also located in the community of New Strawn (indicator location 32) and a control location at Harris (location 48). Supplemental indicator location (location 18) was also sampled during the year. Distances and directions to sampling locations from the plant are listed in Table 2, indicator locations are shown in Figure 1, and the control location is shown in Figure 5.

B. Direct Radiation Pathway Panasonic UD-814 TLDs were used at 43 locations during the sample year. The TLDs consist of one lithium-borate element and three calcium sulfate elements in a plastic case.

TLDs were typically positioned roughly 3 to 4 feet above the ground in plastic thermostat boxes.

The thermostat boxes protect the TLDs from the elements and tampering. Two TLDs were placed at each designated location.

The TLDs were changed out quarterly. Indicator TLD sample locations are illustrated in Figure 2 and control locations are shown in Figure 5. Table 2 provides the distance and direction of each location from the plant. Control locations were 39 (Beto Junction) and 48 (Harris).

C. Waterborne Pathway All water samples were analyzed to determine whether gamma emitters were present.. In addition to gamma isotopic analysis, radiochemical analysis for 1-131 was performed.: on drinking water and ground water samples. Gross beta analysis was also performed on drinking water samples. Tritium analysis was performed monthly by liquid scintillation for surface water and quarterly for drinking water.

Tritium analysis was also performed on ground water samples. Water sampling locations are listed in Table 2 and are shown in Figures 3 and 5.

Monthly grab samples of surface water were collected from John Redmond Reservoir (JRR) as a control location and from the "SP" location, which is located near the spillway of Coffey County Lake, formally known as Wolf Creek Lake, as an indicator location.

2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 30

Quarterly grab samples of ground water were collected from seven wells.

Location B-12 is hydrologically up gradient from the site and was used as a control location. Six locations (C-10, C-49, F-i, G-2, J-1 and J-2) are hydrologically down gradient from the site and were used as indicator sample locations.

Drinking water was sampled at the water treatment facilities for the towns of Burlington (control location BW-1 5) and Iola (indicator location IO-DW). The Burlington facility is located upstream and the Iola facility is located downstream of the confluence of the discharge from Coffey County Lake and the Neosho River.

Composite samples were obtained monthly from automatic samplers at each location that collected approximately 27 ml of drinking water every two hours.

Shoreline sediments were sampled semiannually. Gamma isotopic analysis was performed on the shoreline sediment samples. Shoreline sediment sample locations were the Coffey County Lake discharge cove (DC) indicator location and at the control location (JRR).

D. Ingestion Pathway Because no sampling locations that produce milk for human consumption were identified within five miles of the plant, milk was not collected during the sample year.

Fish were sampled semiannually from the tail waters of JRR (control, Figure 4) and from Coffey County Lake (indicator, Figure 4). Gamma isotopic analysis was performed on the boneless meat portions of the fish.

Several species of game fish and rough fish were sampled. Fish were also analyzed for tritium.

Broadleaf vegetation samples were collected monthly when available during the growing season from four gardens. Three indicator (C-2, N-1 and Q-6) gardens (Figure 4) and one control (D-2) garden (Figure 5) were sampled. Gamma isotopic analyses were performed on all samples.

Crop samples were obtained from two indicator locations (NR-D1 and NR-D2) downstream of the confluence of Wolf Creek and the Neosho River. Two crop samples were obtained from control location NR-UI.

Gamma isotopic analysis was performed on each sample.

Crop sample locations are identified on Figure 5.

E. Additional Samples Collected (not required by ODCM)

Quarterly, duplicate ground water grab samples were obtained from indicator location C-49 and were labeled L-49. These duplicate samples served as laboratory quality checks. The ground water samples were analyzed for gamma emitters, 1-131 and tritium.

Shoreline sediments were collected at the Black Bear Bosin area (BBB) and the SC (Stringtown Cemetery).

Gamma isotopic analysis was performed on the shoreline sediment samples.

These indicator samples were collected as part of a cooperative sampling effort with the Kansas Department of Health and Environment (KDHE). The sample locations are identified on Figure.3.

Bottom sediment samples were collected at the Environmental Education Area (EEA) and from the Make-Up Discharge Structure (MUDS).

Gamma isotopic analysis was performed on the 2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 30

The sample locations are identified on Figure 4.

Soil was sampled from indicator locations MUDS and EEA.

Gamma isotopic analysis was performed on the soil samples.

These samples were collected as part of a cooperative sampling effort with the KDHE. The sample locations are identified on Figure 4.

Distance and direction information for the sampling locations listed in this section are outlined in Table 2.

II. DISCUSSION OF RESULTS Analysis results for all pathways are summarized in Appendix B using the format described in Radiological Assessment Branch Technical Position, Revision 1, November 1979 (NRC Generic Letter 79-065). Results for individual samples are listed in Appendix C.

In this section, results are discussed by pathway and analysis type.

Monitoring results,are compared with control data, preoperational values, sources of radioactivity, and effluent releases when applicable. Trends or seasonal effects are discussed.

A. Airborne Pathway Chart 1 graphically illustrates weekly gross beta results for the sample year. Chart 2 represents the historical smoothed averages of indicator and control gross beta data.

Charts 1 and 2 demonstrate how closely the indicator and control locations tracked together.

Chart 2 reveals a seasonal cyclic trend in which gross beta values peak in the winter months (December or January) and decrease to a low point in the spring months (May or June). This trend is expected and is attributed to seasonal meteorological changes, i.e., changes in prevailing winds and precipitation.

2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 30

The gross beta results of 2007 were compared to pre-operational monitoring results of 1983 and 1984.

The weekly gross beta analyses range for' 1983 and 1984 was 0.0064 to 0.084 pCi/m 3. The 2007 weekly gross beta analyses range for indicator locations was 0.010 to 0.062 pCi/m 3, which was within the 1983 and 1984 pre-operational range. Additionally, the annual mean for indicator locations for 2007 (0.030 pCi/m 3) was lower than the annual mean for 1983 (0.032 pCi/m 3).

The gross beta results for the indicator locations were also compared to the control location.

The annual mean for indicator locations for 2007 (0.030 pCi/m 3) was similar to the annual mean of the control location (0.029 pCi/m 3).

Naturally occurring Be-7 activity was detected, as was the case during pre-operational monitoring.

In 1984, the range for Be-7 detected activity was 0.024 to 0.211 pCi/m 3 for indicator locations, and the annual mean for indicator locations Was 0.069 pCi/m 3. In 2007, the range for Be-7 detected activity was 0.060 to 0.114 pCi/m 3 for indicator locations, and the annual mean for indicator locations was 0.091 pCi/m 3.

The control location annual mean for Be-7 detected activity (0.087 pCi/m 3) was similar to the indicator locations annual mean (0.091 pCi/m 3).

1-131 activity was not detected in the weekly analysis of charcoal filters at any location.

No effects of plant operation were seen via the airborne pathway for the year, and no unusual trends were noted.

B. Direct Radiation Pathway Quarterly gamma exposures measured at each location are shown in Table 3.

Measured values have been converted to a standard 90-day quarter.

The annual mean of all indicator locations in 2007 was 0.212 mR/day and the annual mean for the control locations was 0.210 mR/day. For pre-operational comparison, in 1981, the annual mean of all indicator locations was 0.21 mR/day and annual mean for the control locations was 0.19 mR/day.

Results from TLDs located near the plant (less than three miles), which would be most affected by changes in plant operation, were combined into quarterly averages.

These nearsite averages, using locations 1, 2, 7-9, 11-14, 18, 26, 27, 29, 30, 37 and 38 are compared to control location results (locations 39 and 48) in Chart 3. Chart 3 also includes preoperational data for comparison.

The nearsite TLD locations have historically trended higher than the control locations both prior to and after WCGS became operational.

C. Waterborne Pathway (1) Surface Water Tritium, attributable to WCGS operation, was detected in all surface water samples collected from Coffey County Lake during 2007. Chart 4 illustrates the yearly averages of surface water tritium data for the spillway location. Chart 4 shows that the average tritium concentration of 2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 30

the lake may have reached equilibrium since the last four years indicate a slightly downward trend.

ODCM required lower limits of detection were met and tritium activity was not detected in samples obtained from the control location (JRR).

During pre-operational environmental radiological monitoring, measured radiological activity was not detected in surface water samples.

Tritium was the only activity detected in surface water samples and no unusual trends were noted.

(2) Ground Water ODCM required lower limits of detection were met and radioactivity was not detected in any ground water samples.

(3) Drinking Water Chart 5 illustrates the drinking water gross beta results for the last five years and how closely the gross beta results compared for the indicator and control locations.

Gross beta activity was detected in all drinking water samples. The annual mean of the control location gross beta activity (3.0 pCi/L) was similar when compared to the annual mean of the indicator location (3.2 pCi/L). The 2007 annual means of gross beta activity for both the control and indicator locations were lower than those of the pre-operational monitoring year of 1984. In 1984, the annual mean of the control location gross beta activity was 6.4 pCi/L, and the annual mean of the indicator location gross beta activity was 7.5 pCi/L.

ODCM required lower limits of detection were met.

Additionally, radionuclides were not detected by the 1-131 or gamma isotopic analyses.

Activity due to plant operation was not evident in drinking water samples during 2007 and no unusual trends were noted.

(4) Shoreline Sediment Naturally occurring K-40 was detected in samples obtained from the indicator location (DC) and in samples obtained from the control location (JRR).

K-40 was also detected during pre-operational shoreline sediment monitoring.

Cs-137 activity was also detected in one shoreline sediment sample obtained from the control location (JRR).

ODCM required lower limits of detection were met. Activity due to plant operation was not evident in shoreline sediment samples during 2007 and no unusual trends were noted.

2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 30

D. Ingestion Pathway (1) Milk Milk was not collected during the sample year since no indicator locations within five miles of the plant were identified during the Land Use Census.

(2) Fish Naturally occurring K-40 activity was detected in all fish samples.

K-40 activity was also detected during pre-operational fish monitoring.

During 2007, fish were also analyzed for tritium. All fish samples taken from Coffey County Lake had tritium activity detected (6,475 pCi/kg annual mean). The detected tritium activity was attributable to plant operation.

An adult consuming 21 kilograms of fish, at the maximum measured tritium concentration for 2007 (7,266 pCi/kg), would receive a committed effective dose equivalent of 0.010 mRem.

Tritium activity was not detected in the control samples collected from JRR.

No other radionuclides were detected in fish during the year. The ODCM required lower limits of detection were met and no unusual trends were noted.

(3) Broadleaf Vegetation Gamma analyses of broadleaf vegetation samples obtained from indicator and control locations detected naturally occurring gamma emitters Be-7 and K-40. Be-7 and K-40 activity were also detected pre-operationally.

The ODCM required lower limits of detection were met and no unusual trends were noted.

Activity attributable to plant operation was not detected.

(4) Crop Samples Gamma analysis detected naturally occurring K-40 to be present in all of the samples. K-40 activity was also detected during pre-operational crop monitoring.

K-40 was the only activity detected in crop samples.

The ODCM required lower limits of detection were met and no unusual trends were noted.

E. Additional Samples Collected (not required by ODCM)

(1) Bottom Sediment Naturally occurring K-40 was detected in all of the bottom sediment samples. K-40 activity was also detected during pre-operational bottom sediment monitoring.

Co-60 activity (107.9 and 88.7 pCi/kg) was detected in the indicator samples obtained from the Coffey County Lake discharge cove. Co-60 activity was attributable to plant operation and has been identified in plant effluents.

Co-60 activity was not detected in pre-operational environmental monitoring and was not detected in samples collected from control location JRR 2007 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 30

during 2007. Chart 6 plots the Co-60 detected activity from the discharge cove and reflects a decreasing trend. This downward trend is due to improvements made in the process system.

Cs-137 activity (179.8 and 167.7 pCi/kg) was detected in the indicator samples obtained from the Coffey County Lake discharge cove. A portion of this activity is due to fallout and a portion of this activity is likely plant-related since Cs-1 34 activity has been detected in the past. Cs-1 37 activity was detected in pre-operational samples, and the. results for 2007 indicator bottom sediment samples were within the pre-operational range. (Cs-137 activity detected in 1981 and 1982 was in the range of 79 to 953 pCi/kg.

The decay corrected range of pre-operational Cs-137 activity detected is approximately 44 to 525 pCi/kg.) Cs-137 activity has been identified in plant effluents. Cs-137 activity (121.5 and 129.3 pCi/kg) was also detected in the control location (JRR) bottom sediment samples.

Chart 7 plots the Cs-137 detected activity from the discharge cove indicator location and JRR control location bottom sediment samples. The detected Cs-137 activity measured from the discharge cove location reflects a decreasing trend. The Chart 7 trend line indicates that as expected, Cs-137 activity detected at the JRR control location has been decreasing.

No other radionuclides were detected in bottom sediment samples and no unusual trends were noted.

(2) Aquatic Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2007. Be-7 and K-40 activity were also detected during pre-operational monitoring.

No other radionuclides were detected in aquatic vegetation samples and no unusual trends were noted.

(3) Terrestrial Vegetation Naturally occurring Be-7 and K-40 activity were detected in samples collected in 2007.

No other radionuclides were detected. No unusual trends were identified.

(4) Soil Naturally occurring K-40 activity was detected in both of the soil samples. K-40 activity was also detected during pre-operational soil monitoring.

Cs-137 activity (326.4 and 446.2 pCi/kg) was also detected in both of the soil samples. This activity is likely due to fallout. Data was reviewed for soil samples collected pre-operationally.

The Cs-137 range from February of 1985 was 255 to 2,160 pCi/kg, dry. The decay corrected range of pre-operational Cs-137 activity detected in soil is approximately 153 to 1,296 pCi/kg.

The detected Cs-137 is well within the pre-operational decay corrected range.

No unusual trends were identified.

III. PROGRAM REVISIONS/CHANGES Based upon results from the corrective action program, the following TLD locations were added to the program during January 2007: 46, 44, 50, 51 and 52. The following TLD locations were removed from the program:

3, 10, 6, 21, 28, 31 and 33. These changes were made to enhance the effectiveness of the program.

On February 21, 2007, air sample pumps with digital flow meters were installed. Change was made to enhance air sample volume data that is used to calculate concentration.

IV. PROGRAM DEVIATIONS Air Samples The air sample locations listed below failed to meet the requirement for "continuous sampler operation." As described in footnote (1) of procedure AP 07B-004, Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program), Table 5-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons. Discrepancies greater than five percent between Total Military Time and Total Digital Flow Meter Time, which resulted in a loss of air sample collected, are listed in the following table.

V. INTERLABORATORY COMPARISON PROGRAM RESULTS During 2007, Environmental, Inc., Midwest Laboratory was contracted to perform radiological analysis of environmental samples for WCNOC. The lab participated in the intercomparison studies administered by Environmental Resources Associates.

Appendix A is the Interlaboratory Comparison Program Results for Environmental, Inc., Midwest Laboratory.

Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also contained in Appendix A.

VI. COMPARISON TO THE RADIOACTIVE EFFLUENTS RELEASE PROGRAM As described in the section discussing radioisotopes found in fish from Coffey County Lake, dose that may be received as a result of tritium released from WCGS is comparable with the theoretical doses calculated by the Radioactive Effluent Release Program.

The theoretical doses calculated by the Radioactive Effluent Release Program assume that a person drinks the water from Coffey County Lake and eats the fish from Coffey County Lake.

Based upon these assumptions the dose to man from both pathways was calculated to be 0.110 mRem for 2007.

Using sample data obtained from the REMP, an adult drinking 2 liters per day of surface water from Coffey County Lake, using the average tritium activity (10,442 pCi/L), would receive a committed effective dose equivalent of 0.477 mRem per year. For an adult eating 21 kg of fish per year from Coffey County Lake, using the average tritium activity (6,475 pCi/kg), would receive a committed effective dose equivalent of 0.009 mRem per year. Based upon the REMP results, the dose from both pathways was calculated to be 0.486 mRem per year.

It should be noted that the Coffey County Lake is not a drinking water source. Calculating the dose to man for tritium detected in the Coffey County Lake surface water is for comparison purposes only.

The tritium dose values are being compared on a qualitative basis. It is not expected that the annual doses, as calculated in the Radioactive Effluent Release Report, would compare directly to those calculated from the REMP. The Radioactive Effluent Release Report provides a 'snap shot' of potential dose resulting from the year's releases.

The REMP data indicates the accumulated result of releasing tritium into the lake since the start of plant operation.

Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year-, the complete Appendix is included in March, June, September and December monthly progress reports only.

January through December, 2007

Appendix A Interlaboratory Comparison Progqram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's 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 issuing agency. 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.

The results in Table A-2 list 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 month, 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 acceptance criteria for "spiked" samples.

Out-of-limit results are explained directly below the result.

EXECUTIVE

SUMMARY

The annual Land Use Census of rural residents within five miles of the Wolf Creek Generating Station (WCGS) has been completed for 2007 in accordance with AP 07B-004, [Offsite Dose Calculation Manual (Radiological Environmental Monitoring Program)].

No program changes are necessary regarding milk locations. Again, no milk sampling locations were identified.

Changes are not required for the Radiological Environmental Monitoring Program (REMP) broadleaf vegetation sample locations for 2008. The two broadleaf vegetation locations with the highest calculated annual average D/Q rankings are Q2.35-MILA1619 and N2.38-RRDR9.

AP 07B-004 specifies that an "alternate location may be used to provide continued monitoring".

The third-ranked garden is location C1.92-16RD1655. It should be noted that locations Q2.35-MILA1619, N2.38-RRDR9 and C1.92-16RD1655 were established sampling locations for the 2007-growing season.

The 2007 Land Use Census Report has been revised to add a trailer house residence located in Sector B. This location is the closest occupied residence in Sector B.

BACKGROUND Section 5.2, Attachment A, of the ODCM procedure (AP 07B-004), directs that "a Land Use Census shall be conducted annually during the growing season to identify the nearest (1) milk animal, (2) residence, and (3) garden of greater than 500 square feet producing broadleaf vegetation in each of the 16 meteorological sections within five miles of the WCGS site" and "the results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report."

Table 5-1, Attachment A, of the ODCM (AP 07B-004) requires that broadleaf vegetation samples be collected from 'two indicator locations with highest calculated annual average D/Q."

Table 5-1, Attachment A, of the ODCM (AP 07B-004) also requires that milk samples be collected from "three indicator locations within 5 miles of the site having the highest dose potential."

METHODOLOGY Two hundred fifteen surveys were mailed to the rural residents living within five miles of WCGS.

A follow-up survey was sent to residents who did not respond.

The survey excluded the residents of New Strawn, Burlington, and a trailer park north of Burlington. These locations were excluded due to the large number of households and the low likelihood that information gained from these residences would affect the locations chosen for REMP sampling. Drive-by information was collected for the nearest residences that did not return surveys.

The information collected was compiled and the results are identified in Tables 1-3.

Calculations were performed so that garden locations could be ranked by their respective D/Q.

These results are contained in Table 4.

RESULTS NOTE: A Global Positioning System was used to verify residence distances and sectors.

As identified in Table 2, sector B experienced a change in the nearest occupied residence.

Five location changes were noted for the nearest garden producing broadleaf vegetation.

These changes are identified in Table 3.

There were no changes regarding milk sample locations. Again, no locations were identified that routinely milked animals for human consumption.
