"Sterile gauze swabs were placed at 21 stations for 

 about five days. Salmonellae were found at five of the 

 stations (poulty plant effluent). The United States 

 Public Health Services Communicable Disease Center 

 determined the serotype. The results clearly pointed out 

 that poulty plant wastes are pathogenic to man since all 

 Salmonella bacteria are pathogenic. Salmonellae were 

 isolated from both swabs placed in the Penobscot River. 



"The Maine Water Improvement Commission found that the 

 dissolved oxygen placed the Penobscot River either in the 

 nuisance condition or in Class D (Suitable for trans- 

 portation of sewage and industrial waste without causing 

 a public nuisance.) from Bangor to Bucksport. Zero 

 D.O was found from Bangor to Winterport during the summer 

 of 1963, with the oxygen sag curve moving downstream at 

 low tide and upstream at high tide. This dissolved 

 oxygen condition limits usage of the entire river below 

 Bangor and prevents fish, including anadromous fish such 

 as salmon, from Dassing through these waters." 



Another problem is Sulfite Waste Liquor resulting from the processing 

 of pulp using the sulfite process. Bioassays of Pulp Mill Wastes 

 with Oysters, Biological Problems in Water Pollution , U.S. Depart- 

 ment of Health, Education, and Welfare, Cincinnati, Ohio, 1965 

 showed that concentration of SWL above 10 ppm prevented the embryonic
