Two, cause extensive bottom sludge deposits 

 which produce toxic concentrations of sulfides in the 

 adjacent waters. This is damaging to fish and bottom 

 organisms and results in over-all aesthetically unattrac- 

 tive conditions in the harbor. 



And three, the wastes have been shown to 

 cause suppression of phytoplankton activity in the Everett 

 Harbor area . 



The concentrations of sulfite waste liquor 

 found in the surface waters throughout the study area 

 present an even greater threat to the indigenous marine 

 communities. These wastes in dilute concentrations, 

 again a 5 per 15 parts per million sulfite waste liquor, 

 have been shown to be damaging to larval forms of fish and 

 shellfish found in this area. 



The Project studies have shown that such 

 wastes : 



Produce damages to developing English sole 

 eggs found throughout the surface waters of Port Gardner 

 and Everett Harbor. Extensive damage or mortality would 

 be expected in and adjacent to Everett Harbor, with the 

 degree of damage decreasing with distance from the waste 

 source . 



They have also been shown to produce
