Introduction The. data obtained by analysis of samples, taken* *during 1979, has been evaluated to determine if any increases in radioactivity levels in the environment are attributable to plant operation.

A summary of the data,_is presented in Table A-1.

Figure A-1 and Table A-2 provide the locations of the sampling st.ations. Statistical analyses of the data show.that there has been no detectable increase in radioactivity levels of environmental media that can be attributed to plant effluents.

Discussion and Internretation of Results (a). Air Samples (b)

Statistical analyses (at p <O.. 05) of the air particulate sampling results do not indicate a significant difference in gross beta.

concentrations between the indicator and background stations,.

except during October and November.

During October,*the indicator locations were statistically lower than the background stations and in November, the indicator stations were statistically higher than the background locations.

When -the 4th quarter gross beta

.results were grouped to increase the statistical population, no differences* could be identified.

During the period in question, the concentration differential is significantly less than 10CFR20 limits.

The 4th quarter operating and effluent data was reviewed and the following information noted.

The Palisades Plant did not operate during the 4th quarter of 1979, however, the gaseous particulate effluent's did increase, but re-mained a small fraction of the Technical Specification release limit (0.006%).

Table A-:5.provides the results of the November air sampling gross beta analyses.

No.significant iodine-131 activity was observed above the minimum detectable level.

This is consistent with expected results based on actual plant effluents and site meteorology.

Lake Water Monthly composite samples show no significant difference in gross beta concentrations between the two sampling locations.

All gross beta concentrations were. less than 6pCi/i, except one intake sample analysis.of 37 pCi/i:

The cause of this unusual result could not be determined.

Tritium concentrations ranged from <100 to 5100 pCi/i.

l.1*.

'o (c)

Drinking Water Monthly composite samples of treated and untreated South Haven municipal water indicate only background activity.

Gross beta activity ranged from less than 1 to 5 pCi/L Tritium activity (treated water only) ranged from less than 100 to 340 pCi/~.

( d)

Well Water Monthly grab samples of three sampling locations showed concen-trations ranging from 1 pCi/~ to 15 pCi/~. The gross beta

concentrations at location. SP was statistic8.lly higher than the other two locations at p <0.05, however, when SP is compared with previous years' results, no significant difference is.

identified.

. (e)

Milk Stronti tnn-90 and cesi um-137.*were the. only rad~onuclides *detect-

. able in milk samples collected during the year.

Concentrations of these two isotopes are consistent with concurrent background.

( f)

Sediment and. Crops.

Radioactivity in lake bottom sediment. and crop samples collected throughout the year is.consistent with previous years data.

(g)

Gamma Dose Thermoluminescent dosimeters are used to monitor the levels of gamma radiation in the viCinity of the site.

No significant differences in radiation levels were observed among the various sampling locations.

3.

Sampling Summary For each media sampled, Table A-3 lists the sampling locations and the total number of. samples collected. A listing of the highest, lowest and average concentrat"ions for the sampling location with.the highest average concentration is presented in Table A-4.

4.

Environmental Dose Estimates Levels ofradioactive materials in environmental media do not indicate the likelihood of public exposure. in excess of 5% of those that would result from continuous exposure to the concentration values liste9, in Appendix B, Table II, 10CFR20.
