2 1. Substandard concentrations of dissolved 



3 oxygen, to 4.9 parts per million, were detected In 



4 Belllngham Harbor. 



5 2. That sulfite waste liquor concentra- 



6 tions were detected in all stations in Bellingham Harbor 



7 and nnany of the concentrations in excess of the known toxic 

 g limits for salmonoid fishes. 



9 3. Sulfite waste liquor concentrations, 



10 as indicated by the Pearl-Benson test, were found to be 



11 widely distributed throughout the survey area. A maximum 



12 of 45 parts per million was detected over a commercial 



13 oyster growing area in Samish Bay. 



14 In 1960, Pacific oyster larval bioassays 



15 reported by Charles Woe Ike of the State Fisheries Depart- 

 15 ment summarized findings as follows: 



17 "Fresh sulfite waste liquor affected 48- 



Ig hour development of fertilized Pacific oyster eggs at 



19 concentrations of 2 parts per million and greater; above 



20 18 parts per million, fresh sulfite waste liquor caused 



21 100 percent of the developing 48-hour larvae to be ab- 



22 normal; in some experiments over 90 percent of the larvae 



23 were abnormal at 12 parts per million." 



24 In 1962 a water quality study of Bellingham 



25 Bay by the Fisheries Department summarized that study as
