Wastewater Treatment Plant Monitoring and Assessment

Image of the Metropolitan Wastewater Treatment Plant outfallMetropolitan Council Environmental Services monitors the quality of the treated wastewater discharged from eight Twin Cities metro area  wastewater treatment plants into area rivers. Effluent toxicity-testing is conducted regularly to meet National Pollutant Discharge Elimination System permit requirements, and help ensure that the treated wastewater is safe to enter area rivers.

We also conduct groundwater monitoring  at several wastewater treatment plants.
