Abstract Wastewaters from six municipal wastewater treatment plants in Ohio were tested at different stages of treatment for mutagenicity in the Ames/Salmonella assay. The chlorinated secondary effluents were also evaluated for induction of sister chromatid exchanges in Chinese hamster ovary cells. Direct-acting microbial mutagenicity was observed for extracts of the effluents from all six plants for both an initial and a repeat sampling series. In some cases, the mutagenicity was greatly enhanced by S9 metabolic activation (MA). In general, the specific mutagenicity of the extracts increased following activated sludge treatment. Chlorination resulted in substantial increases in mutagenic activity for some of the wastewaters but had no effect on others. SCE inducing activity was detected in five out of six extracts for the first sample series, and for two out of five extracts for the second sample series. There was no obvious correlation in the ability of the extracts from the chlorinated secondary effluents to induce SCE in GHO cells and to induce mutations in Salmonella.
