Duluth Streams Escherichia coli Assessment

Several streams within the Duluth metropolitan area are identified as impaired and are included on Minnesota’s Impaired Waters List, with impairments to Aquatic Recreation, due to levels of Escherichia coli (E. coli) bacteria. Total Maximum Daily Load (TMDL) studies have been completed (draft) for these impairments, including Keene Creek and Tischer Creek. The goal of this project  is for the City of Duluth to provide the Minnesota Pollution Control Agency (MPCA) with information on the sources of E. coli bacteria exceeding state water quality criteria (or standards) and to use the information gathered from the study to provide recommendations on Best Management Practices (BMPs) that can be used to achieve the TMDL reduction targets.
