 evaluation of long-term effects of less drastic conditions. 



In recognition of this deficiency in the 

 study we would recommend additional research to investigate 

 this aspect of the problem. We would also recommend that 

 any pollution abatement procedures be considered as 

 minimum measures, with the understanding that it may be 

 necessary to further reduce levels of pollution in the 

 light of future research. 



The same criticism applies to studies of 

 the effect of the pollutants on oysters and other molluscan • 

 shellfish. Long-terra effects of low concentrations of 

 wastes on growth rate and fatness have not been thoroughly 

 investigated in this study. This area requires further 

 research. It may be necessary to amend standards of water 

 quality when additional knowledge provided by such experi- 

 ments becomes available. 



We are also concerned that these studies 

 have not taken into account the changes in water quality 

 which may result from planned industrial installations in 

 or near the study areas. For example, in a recent study 

 by Battelle Northwest regarding siting of nuclear power 

 plants in the Pacific Northwest, looations on Whidby 

 Island, on the Straits of Juan de Fuca, and near Bellinghara 

 were recommended. The 1,000 megawatt thermal electric
