The MPCA, in partnership with the Vermillion River Watershed Joint Powers Organization, contracted with Wenck Associates, Inc., to develop the Stressor Identification (SID) Report; and develop the necessary models for the Vermillion River Watershed Restoration and Protection Strategies (WRAPS) as part of Phase I. The final Vermillion River Watershed SID report discusses all of the analysis that was done in the watershed to identify the primary stressors causing the fish and macroinvertebrate impairments in the watershed.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
