 Further, the limit of deviation, if any, from a water 

 quality standard should be specified at the time the 

 standard is established. The standard method for 

 analysis of marine waters should be the "Manual of 

 Sea-Water Analysis", Strickland and Parsons, (1965) 

 Bulletin No. 125, Fisheries Research Board of Canada. 



Procedures included in "Standard Methods 

 for the Examination of Water and Wastewater" should be 

 employed for analysis of fresh water. We feel that 

 other recognized methods that permit successful repro- 

 ducibility of sample analysis are also acceptable; 

 i.e., the use of bioassays for detection of materials 

 that are at or near the lower limits of detectability 

 Included in " Standard Methods " or "Manual of Sea-Water 

 Analysis". Measurement of water quality as it affects 

 fish or shellfish is best demonstrated by the response 

 of the organism to its environment. Whenever bio- 

 assays demonstrate adverse ecological conditions, 

 results of these bioassays should take precedence and 

 remedial action be initiated. 



We do not believe that the answer to 

 water quality problems lies in litigation of existing 

 laws, but instead requires the co-operation of all con- 

 cerned in a sincere and determined effort to abate
