[1] Measurement of the temporal and soatlal 

 dimensions of sludge fields 

 [2] Chemical analyses of sample sludges from 

 various outfalls with emphasis on substances 

 likely to have biological importance, and 

 [3] Measurement of the rates of biodegradation 

 and utilization of sludge components by marine 

 organisms ^ 

 (c) Determination of the dissolved inorganic and 

 organic substances resulting from coastal discharges 

 and their effects by means of 



[1] A chemical inventory of components, 



[2] Bioassays of both effluents and affected 



waters for toxicity and stimulation, and 



[3] A study of primary productivity and other 



community responses in affected waters. 



(2) A detailed examination of the public health signifi- 

 cance of coastal discharges should be made, including; 



(a) He-evaluation of the adequacy of traditional 

 fresh water biological indices in marine waters and 

 in organisms consumed by man, and 



(b) Development and application of improved indices. 



(3) Research on the biological concentration of waste 

 components by marine organisms should be expanded and 

 intensified. Special attention must be given to organisms
