This report presents seven case studies which illustrate the use of different techniques for diagnosing potential effects of trace organic compounds (TOrC) at a site. The techniques highlighted in the report include: EPA’s causal analysis framework, Causal Analysis/Diagnosis Decision Information System (CADDIS); Canada’s Environmental Effects Monitoring (EEM) causal analysis approach; the consumer products manufacturer’s ROUT model and the pharmaceutical manufacturer’s PhATE model to predict concentrations of certain TOrC at a wastewater influenced site; and ecological modeling (Comprehensive Aquatic Systems Model [CASM]). These case studies represent a range of scenarios and the monitoring information available that most utilities and water resource managers are likely to face. Published by WERF. 150 pages.
