2 However, It does Indicate the presence of sulfite waste 



3 liquor and recall again the levels found during the normal 



4 mill operation as compared to those during the strlke- 



5 downs for all of the areas In which production ceased, and 



6 further If sufficient samples are tested the mean or 



7 average sulfite waste liquor value Is, In our opinion, 



8 significant. 



9 In summary, the field sample study clearly 



10 demonstrated the adverse effect of pulp and paper mill 



11 wastes on the marine environment In that: 



12 The number of abnormal larvae Increased as 



13 sulfite waste liquor concentrations Increased. 



14 The number of abnormal larvae Increased as 



15 the distance from each mill's discharges decreased and, 



16 conversely, sulfite waste liquor Increased. 



17 When the mills were not operating, as 



18 during the November '64 strike, larval abnormality and 



19 sulfite waste liquor values dropped to near zero in the 



20 strlke-a iffected study areas, but both these parameters 



21 remained at about the usual level In the Everett study 



22 area where the Weyerhaeuser Mill continued at 60 percent 



23 production. 



24 And when production was resucned in the strike- 

 affected areas, larval abnormalities climbed immediately
