| Abstract |
The water quality and fish communities in streams receiving chlorinated effluents from 156 secondary sewage treatment plants in Virginia, Maryland, and Pennsylvania were studied during the summers of 1968-1970. The water quality parameters considered were total chlorine, ammonia nitrogen, total phosphate, deterbent (AMS), conductivity, turbidity, hardness, chlorides, acidity, alkalinity, dissolved oxygen, pH, and nitrite-nitrate nitrogen. Changes in fish community diversity in the streams were related to these parameters. Several recommendations on plant designs and on selection of outfall sites to achieve natural purification are presented. |
| Highlights Notes |
Describes types of pollutants occurring with chlorinated effluents from 156 secondary sewage treatment plants in Virginia, Maryland and Pennsylvania and suggests natural purification methods through plant design and outfall sites aimed at protecting the fish population that could supplement present sewage treatment methods. |
