Chlorinated wastewater effluents

Chlorine or chlorination agents are used by many wastewater treatment plants in Canada in order to disinfect effluent prior to its discharge into the receiving environment. Effluent wastewaters are disinfected to protect downstream municipal water supplies, recreational waters and shellfish-growing areas from bacterial contamination and other agents causing waterborne disease.  Studies have demonstrated that certain levels of chlorinated wastewater effluents from wastewater treatment plants have caused acute lethality to fish and invertebrate species. Chlorinated wastewater effluents were added to the List of Toxic Subs tances in Schedule 1 of the Canadian Environmental Protection Act in November of 1999.
