The Hudson-Raritan Estuary is a typical urban estuary that receives a tremendous burden of pollutants from many point- and non-point sources. Treated municipal wastewater (TMW) accounts for about 13% of the freshwater input, 90% of point-source volume and >98% of point-source pollutants. Most sources of TMW have a substantial industrial input, so the effluents include organics and heavy metals. While secondary treatment substantially reduces TMW toxicity, chlorination of the effluent restores the toxicity by producing oxidized and chlorinated compounds not previously present. The authors are attempting to assess the biological impacts of such effluents. They report here results to date of laboratory analyses of realistic dilutions of such secondarily-treated and chlorinated TMW. They have targeted three species of fish common to the Hudson-Raritan Estuary, the winter flounder (Pseudopleuonectes americanus), the mummichog (Fundulus heteroclitus) and the striped bass (Morone saxatilis). The estuary is a spawning area for the first two species and a significant overwintering area for the third, a protected species. Because the early life stages of fish are especially sensitive, they are focusing on development and growth.
