site. Since, the spoils at New London are relatively stable, it is puzzling 

 to find no physical evidence of spoils at Cornfield Shoals. It may be that 

 the residual current component at Cornfield Shoals is significantly greater 

 than that at New London, however, better data are required before that can be 



determined . 



Sedi ments 



Heavy metal analysis of sediments from the Cornfield Shoals disposal site 

 are presented in Table G-2. Although most samples at this site are among the 

 cleanest found in the entire New England study area, two samples from the point 

 of dumping (Corn DS-2, from March and July) have extremely high concentrations 

 and enrichment relative to iron. Thus, it is apparent that although no spoil 

 mound has been formed at this site, spoils are present in the area as isolated 

 patches. Future sampling will be oriented toward determing the extent and dis- 

 tribution of this spoil. The impact and extent of this and future dumping 

 should be readily discernable because of the great difference in composition 

 between spoils and surrounding sediments. 



Biochemical Studies 



At the Cornfield Shoals disposal site and reference station Myti 1 us eduli s 

 collected on January 16, 1978 from Latimer's Light were placed on the mussel 

 cages and used to construct the 95% confidence limits for statistical analysis. 

 The cage at the disposal site was located at 41 o 12' 37.4"N, 72° 21 ' 56 "W and the 

 reference station was located approximately 1 mile north of the site at 

 41° 1 3 "44.1 ' N, 72° 22' 24.1" W in 30 meters of water south of Long Sand Shoal. 



The baseline data from Latimer's Light and results obtained from samples 

 at the sites are presented in Table G-3 and Figure G-5. With the exception of
