Description:
The report describes the first site study on Scippo Creek at Circleville, Ohio, which receives only one discharge from a chemical resins plant using batch operations. Scippo Creek is a small sunfish/bass stream flowing through an agricultural area in central Ohio. Previous biological studies by the State of Ohio had shown measurable adverse impact below the outfall and a grab sample of effluent tested before the study indicated high toxicity. Effluent dilution toxicity tests were run with two test species both onsite and at a remote laboratory. In addition, toxicity tests were conducted onsite on ambient samples from four river stations. Biological studies were conducted at those stations and included benthic macroinvertebrates, fish, and periphyton.
