Isolation of enteroviruses from oxidation pond waters

Abstract

Enteroviruses were isolated from influent and effluent wastewaters of two types of oxidation lagoons during an 18-month study. Isolations, performed by sewage concentration and direct assay, were low in number and did not follow a seasonal trend. The younger treatment system, using aeration and effluent chlorination, was more efficient at removing viruses than the aging, static complex.
