of fresh unpolluted seawater (laboratory water supply) 

 were made. For each waste sample ^ percent-abnormal values 

 from the several dilutions were plotted on probit paper 

 against the appropriate dilution ratios and SWL concen- 

 trations. From the line of best-fit, dilution ratios 

 and SWL values for the 0, 20^ 50, and 100^ abnormal levels 

 were determined. 



"All bioassays and associated laboratory 

 analyses were performed or supervised by Charles E. Woelke 

 of the Laboratory's staff. The results of the waste-sample 

 study were analyzed and evaluated by Mr. Woelke; the re- 

 sults of the field-sample response study were statisti- 

 cally analyzed by Dr. Gerald J. Paulik, Biometrician, 

 University of Washington School of Fisheries. 



"The results of the field-sample study are 

 fully presented and discussed by Dr. Paulik in a final 

 report to the Project. However, only those data (l) 

 derived from or associated with bioassay responses not 

 influenced by low salinity and poor test-animal stock 

 and (2) those associated with normal mill operations, 

 i.e., the usual ranges of water quality and environmental 

 factors prevailing in the study area--are included here. 

 The rationale for limiting the data is given in the Project's 

 final report.
