Microbiological Study of Faunal Response to Spray Irrigation of Chlorinated Sewage Effluent.

摘要

The microbiological effect was investigated of chlorinated sewage effluent on the environment and related animal populations from June 1972through August 1973. The chlorinated effluent was sprayed on sections of Pennsylvania State Gamelands 176. Samples of the effluent,ponds in the area,and fecal samples of white-tailed deer, cottontail rabbits,and songbirds were obtained and analyzed. The total coliform,fecal coliform,and fecal streptococci counts of the effluent and sludge-injected effluent clearly illustrated that these bacterial agents are being introduced into the environment. These results further demonstrated that the sludge-injected effluent spray contributed higher levels of contamination to the environment than the spraying of effluent alone.
