In t rc 9 uct i-on Section 4.2.1. of the Environrental Technical Specifica-tions (E.T.S.) for Three-Mile Island (T:".I-1) Nuclear Station requires the monthly sampling of surface water fren invertebrate nonitoring stations 2 and 3 (Figure 1) and analysis for heavy metals (Cu, Cr, Fe, Mn, Ni and 2n).

Station 2 serves as the upstream site, while station 3 serves as the plant discharge site. This report presents the above-required data for samples collected by Ichthyological Associates, Inc. (I.A.) from February 24, 1976 to "ovember 2, 1976. I?nfavorable weather conditions prevented sample collection during both January and December.

As recuired by section 4.2.2 of the E.T.S., surface

' samoles from all five stations were collected seni-ronthly by I.A. from April 6, 1976 to October 19, 1976. Samples were analyzed for heavy metals (see above) , calcium, magnesium, sodium, potassium, and phenols. The analytical results are presented below.

All results have been forwarded on a monthly basis to personnel of the Radiation Safety and Environmental Engineering Section of the Metropolitan Edison Company.

Results

's . E.T.S., Section 4.2.1: "onthlv Heacy '>etals Analysis The results of the monthly neavy metals analysis for 1976 are shown in Table 1. The "above intake" results are those found for samples collected at invertebrate station 2, and the " discharge" results are those for samples collected at station 3.

Table 2 lists the mean concentration, the highest and lowest values, and the standard deviation from the mean for each metal at the two stations for 1976. Also shown are the data from previous reports for 1974(2) and 1975 (3) ,

Data below concentration reporting limits were not used to calculate the mean values.

In 1976, for all metals except iron, the mean values at the intake and discharge were within the standard deviations of the range of values at each station. This indicates that no major difference in metal concentration exists between the two stations. For iron, the mean concentration of 1.34 pcm at discharge is slightly above the upper range of the mean standard deviation above intake value , which is 1.03 + 0.28 ppm = 1.31 ppm. Also, the mean concentration at intake, 1.03 ppm, is slightly below the mean standard deviation at discharge, 1.34 - 0.21 =

1.13 ppm. This difference is so small, however, that one can say that the increase in the iron concentration at the discharge is virtually insignificant. As can be seen 1565 013

in Table 4, page 10, this slicht increase in iren is easily diluted by tne stream, and ne probicos can be seen.

Ccrparing data fror the three years, it can be seen that the copper and zine results for 1976 fall in the same rance as thosc for the two crevious years. 'danganese and iron data show a slight decrease in 1976, but the standard deviations of the mean for manganese indicate that the difference in values is only slight. Note also, that for iron, the large "high" values of 1974 and 1975 are not present in 1976, but the " low" values of all three years generally fall into similar ranges. The data for chromium and nickel show an increase in concentration in 1976 from both 1974 and 1975, mainly because of the larcer "high" values in 1976. Once again, however, the standard deviation of the range of 1976 data indicates that the increase in 1976 may only be slight at most. It also should be noted that the chromium concentration was below reporting limit

+

(0.002 ppm) for five (5) samplings, so the "true" nean values should be lower than those shown in Table 2, in which values below .002 ppm were omitted from computation.

Appendix B shcws the ninirur renortinc concentra-tion #or each parameter for 1976. Figures 2 through 12 display the plots of yearly averace concentratior. vs. station nurter for each paraneter. Statiens 1 and 2 are upstrear of the discharce (station 3), and stations 4 and 5 are downstrear of the discharge. Table 3 shows a sunmary of the 197C mean concentrations of the narameters at each station. The number of values used to calculate the nean, the nean value itself, and the standard deviation of the values frcm the mean are given. Also shown is the rean and standard deviation values, which were calculated after omittinc the high and low values. This data should help eliminate any effects due to unusually high or low values in the set. It can be seen that the mean values change only slightly when the hich and low values are discarded, indicating that all the values in the range nay be considered to fall within the normal range.

Discussion Conparisons of upstrean and downstream values in Table 3 show little difference (also see Figures 2-11) .

This indicates that even relatively large increases in concentration at the discharge, such as those shown by Fe, Cu, Ni, Zn, Ca , Na and K, are easily accomodated by the stream, and that there is no overall effect on the elemental levels in the stream. In fact, all the mean values downstreas are well within the standard deviations from the mean values upstream. This also is an indication that the downtream concentrations are the same as those upstream.

The large range in values can be seen to originate from the variation of stream conditions with time and weather.

This is best observed by referring to the data in Appendix A.

Even in most of the individual results, the downstream and upstream concentrations are very close.

Table 4 indicates no appreciable differences between mean values for the three years for all but irca, which has a generally lower concentration in 1976 than the previous years. In general, however, the water parameters have remained relatively constant on a year-to-year basis.

In summary, the data indicate no unusual discharges or in'fluences on the water quality at TMI.

Statistical Analysis A. Section 4.2.1 Samples above intake and at discharge The data collected above the intake (station 2) was statistically compared to the data collected at discharge (station 3) by both the paired comparison Student t Test and the non-parametric Wilcoxon signed rank test.

The results are shown in Table A. The superscripts above the elements indicate the appropriate test and level of significance at which the data above intake differs significantly from that at discharge. It would be expected to see some increase in concentration at discharge, and this is shown by Cu, Cr, Fe and Ni. Neither Mn nor Zn show significant difference at any significant level. Agreement is shown between both tests.

?

The chemical assays of semi-monthly samples frce stations 1, 2, 3, 4 and 5 were analyzed statistically using a randomized block analysis of variance. Sample data served as blocks. The Student-Newman-Kuols multirange test was employed to identify station neans which differed significantly.

The results are shown in Table B. 'teans with the same subscript do nct differ dignificantly (p < 0.05). Data for Cr and phenol were not analyzed since determinations were frecuently below the limit of detection. There are essentially no significant differences between the metal concentrations of the water above the discharge and that below the discharge.
