Testing Diagnostic Tools for Trace Organic Compounds and Multiple Stressors Case Studies

The screening Trace Organic Chemical (TOrC) ecological risk approach, developed previously, was evaluated using seven case studies, located in Pennsylvania, Ohio, Colorado, California, and Ontario, Canada. Sites represented a range of complexity, types of biological impacts, and wastewater effluent dilution at low flow. Several different techniques for diagnosing potential effects of TOrCs were incorporated in these case studies including U.S. …
