Introduction As required by the Environmental Technical Specification (E.T.S.) section 4.2.2, water samples collected from inverte-brate monitoring stations (Figure 1) have been analyzed for copper, chromium, iron, manganese, nickel, zinc, calcium, magnesium, sodium, potassium and phenols. Surface samples from each of the five stations were collected on a twice-monthly schedule by Ichthyological Associates, Inc. (I.A.), beginning April 1, 1975 and ending October 21, 1975. The results of the individual analyses have been forwarded on a monthly basis to personnel of the Radiation Safety and Environmental Engineering Section of the Metropolitan Edison Company (Met-Ed).

For monthly heavy metals analysis (E.T.S. section 4.2.1) surface water samples were collected by I.A. at invertebrate stations 2 and 3 from January, 1975 through December, 1975.

Station 2 served as an upstream monitoring site while station 3 served as the discharge location. Results from the inverte-brate station analyses provided the April through October data for these two locations.

Procedures All the analyses employed the analytical procedures spec-ified by the Environmental Protection Agency 1 1556 279 1

s E.T.S. Section 4.2.2: Invertebrate Stations - Water Analyses Results A summary of the analyses is shown in Table 1. The data list the number of detectable concentration values, the average of these values, and the highest and lowest concen-trations found. All concentrations are given in part per-million (PPM).

Discussion Comparison of the average values between the upstream sites (1 and 2), the discharge (3), and the downstream sites (4 and 5) show little difference in the values obtained.

Comparison of the highest values with the lowest ones indicates a somewhat definite concentration range over the sampling period. This indicates that the concentration of each parameter at each station is time dependent. Inspection of the individual analyses indicates that the concentrations vary more with time than between the stations.

The existence of a concentration range for each parameter is due to factors such as rainfall, runoff, tributary drainage into the area, and the resulting river flow rate. A special case is the fact that a severe tropical storm (Hurricane Eloise, September, 1975) occurred towards the end of the sampling period. The resulting flooding due to the heavy rains and runoff in all likelihood influenced the concentra-tion ranges.

This is thought to be the case in the range of concen-trations found for iron. As pointed out in the January 1975 report 2 to Met-Ed, iron concentrations appear to be influenced by river flow rate and suspended solid content.

While no statistical comparisons have been made, a visual comparison of the averages obtained for the same period in 1974 (Table 2) with the present averages indicate no major differences. Where differences are noted they are small and, again, are time related.

E.T.S. Section 4.2.1: Monthly Heavy Metals Results Results The results of the monthly heavy metals analyses are shown in Tables 3 and 4. Table 3 lists the sampling dates and the results of the individual analyses. The "above intake" designation on the table indicates that the data are from invertebrate station 2 located above the TMI-l intake while

" discharge" indicates that the data are from invertebrate station 3. The data are given in ppm.

Taole 4 lists the average concentrations and the highest and lowest values of the data in Table 3. For the purpose of comparison to previous data, Table 4 also lists similar data presented for 19742, Discussion Comparison of the cata in the tables indicates no major concentration differences between the two sampling sitps. No great differences are noted between the 1974 and 1975 data 3 1556 283

either. The only difference noted is that in 1974 the highest iron concentration is 8.0 ppm at the discharge while in 1975 the highest value was 3.2 ppm. It must also be pointed out that the highest iron concentration (10 ppm, Table 1) was found at stations 1 and 3 while analyzing the twice-monthly water samples from the it. vertebrate stations.

In summary, the data listed Tables 1 - 4 indicate that the concentrations of each of the parameters are dependent upon the river conditions at the time of sampling and are independent of station location. No unusual discharges or influences are indicated by these data. Section 4.2.1 of the E.T.S. states that the duration for the heavy metals program is 2 years after startup. Based upon the results presented and the identified monitoring requirement, this program will be discontinued after the March, 1976 collections.
