they werefinally deployed, the disposal site mussels were located at 41°08'59.1 "N, 

 72053"19.1"W and the reference cage at 41 °09 ' 16 .2 "N , 72O54»26.0"W. 



Table H-4 and Figure H-7 summarize changes in the ratios of Cd, Cr, Cu, Hg, 

 Pb and Zn in mussels maintained at New Haven disposal and reference site. Not- 

 able increases in heavy metal concentrations are seen only in Cu and Zn . The 

 concentration of Cu found in mussels from the New Haven disposal and reference 

 sites, as well as Zn in those from the disposal site are significantly higher 

 than that of the baseline. In general, even though the ratios are within the 

 95% confidence limits of the baseline concentrations, the ratios from the dis- 

 posal area are always higher than those from the reference area. 



Samples obtained from the disposal site cage in October "78 revealed that 

 nearly all the mussels at the disposal site had died. Analysis of the mussels 

 recovered is currently underway to determine the reasons for the high mortality. 

 Replacement mussels from Latimer's Light will most likely be deployed during 

 the next cruise to the New Haven area. 



Additional problems have arisen at the New Haven reference site where a 

 dragger has fouled the cage and caused damage, however at this time, the problem 

 does not appear to be severe. 

 Benthic Macro fa una 



Tables H-5 and H-6 present the numerical density data for benth-ic macro- 

 fauna at the New Haven disposal site and reference station. Although, there, are 

 greater numbers of individuals at the New Haven disposal site than at the ref- 

 erence station, other parameters, such as Diversity and Equitability are similar. 



Fisheries 



No comprehensive studies of fisheries have yet been made at this disposal 

 area. In the DAMOS project, fishing activity in the dump site area will be
