Diagnostic Tools to Evaluate Impacts of Trace Organic Compounds

This project had five objectives: 1) develop and apply a procedure to prioritize which TOrCs are of most concern; 2) develop and test a conceptual diagnostic framework to identify TOrCs by source type; 3) develop exposure-response models for high priority TOrCs; 4) develop and populate a relational database of TOrC exposure and effects data; and 5) foster partnerships and transfer knowledge to the water quality community. The final report summarizes approaches used and results obtained, discusses critical data gaps and other uncertainties, and provides testable hypotheses and recommendations for Phase 2 testing and analyses. Companion parts of this project include a TOrC prioritization framework, a report on diagnostic approaches and types of analyses used to identify causes of ecological impairments in aquatic systems, seven case studies, and web-based database (http://traceorganicsecotool.werf.org) to help users search and evaluate TOrC data.
