In addition to the discharge samples provided by the re- 

 actor operators, we obtained series of samples of or- 

 ganisms, of sediments, and of water, in the environments 

 of these reactors, and of the reactor operated by Boston 

 Edison Co., at Plymouth, Massachusetts (Pilgrim No. 1). 

 Most of these samples we collected ourselves but some 

 were provided by the environmental survey teams of the 

 reactor operators. In the Wiscasset area we were sub- 

 stantially assisted, through the good offices of C. T. 

 Hess, University of Maine, Orono, by the people and faci- 

 lities of the Darling Center, of that university. A list- 

 ing of these environmental sampl es , together with their 

 status in analysis, was included in the Progress Report 

 submitted October 1978 under the subject contract. As 

 discussed there, some additional samples have been ob- 

 tained; additional analyses have been performed under an 

 extension of the subject contract, and substantial num- 

 bers, both of samples and analyses, that are highly rele- 

 vant to the interpretation of the NRC-supported work, 

 have been completed with support from other agencies.
