Dear ifr.Wyngarden:
My letter is a quarterly report on progress to date on contract NRC-02-80-076.
I did not submit written reports for the first and second quarters of the contract year because, as you know, most of my effort was in attempting to obtain information from the U. S.
Geological Survey to use in the contract study and you and I had frequent discussions of that by telephone.
During the last quarter, I did succeed in obtaining almost all of the needed available data and I have now began to analyze those data and to undertake modeling of contaminant transport in the glacial aquifer at the United Nuclear Corporation plant site. While I do not as yet have any maps or other results that I would want to distribute, it seems apparent that, as recently as late fall 1982, contaminants were still being carried into the saturated zone in the area where the lagoons were located. Results of sampling after tha spring rains will be very important, as they should show whether or not contaminants are still available to be flushed from the unsaturated zone into the saturated zone.
At this time, I am not optimistic that I will be able to submit a final report by September 17, the end of the contract period. This is because of the uncertainty concerning the amount of contaminants that may still remain in the unsaturated zone. At present, the only means that I have for determining if such contaminants are still present is through evidence from sampling of monitor wells near the lagoon sites.
Since I do not seem to be able to obtain these data for several months after the samples are taken, I do not expect to see the results of the flushing by spring rains until August or September.
If there is then still evidence of new contaminants entering the system, the same uncertainties will exist as do now as to when that contaminant source will.be completely flushed.

Page two - Continued Mr. Stephen D. Wyngarden For the present, I will continue to calibrate the computer transport model so that I will be able to more accurately predict how long it will take for the last of the contaminants to be discharged from the aquifer once they have entered the saturated zone.
I will keep you informed of any sidnificant developments. Please let me know if you wish any further details of the contract work at this time.
Sincercly yours, W
