This was a cooperative effort among the University of Wisconsin-Superior, University of Minnesota-Duluth, and U.S. EPA Environmental Research Laboratory-Duluth to develop and evaluate effluent toxicity screening methods and test methods and protocols for deriving site-specific water quality criteria. The principal components of the study were to include: (1) a chemical characterization of the main discharges to the St. Louis River and Harbor, (2) persistence of toxic pollutants in the St. Louis River and Harbor, (3) a description of the exposure times for various components of the ecosystem, (4) bioassays with St. Louis River water and resident species, (5) an assessment as to the degradation of the biologic community of St. Louis Harbor, and (6) a modeling framework to address items 1 through 5. Because persistent toxic pollutant concentrations were not found in the WLSSD effluent and no persistent open water pollutant problems were apparent, this study was ended. The Project Report contains a series of reports on work completed.
