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.
The goals of Phase I of the Marsh River Watershed (WRW) Watershed Restoration and Protection Strategy (WRAPS) project are to: 1) gather or develop watershed data needed for the development of the WRAPS project; 2) establish project and sub-basin work groups, develop a social outcomes strategy, and develop a civic engagement evaluation strategy to guide the WRAPS project; and 3) begin to identify, create, and organize tools that can be used to determine potential stressors and priority management areas.
The overall project goal is to develop complementary (same year) physical, biological, and chemical data sets for eight agency-prioritized lakes and three streams in NE Minnesota to incorporate into the overall state database for MPCA assessment purposes as well as research purposes.
The objective of the project is to demonstrate controlled drainage and saturated buffers as flood mitigation practices as well as their water quality and quantity benefits. The project is intended to set a compelling example to increase the acceptance and adoption of drainage water management practices in the Red River Valley.Surface and subsurface runoff will be monitored, and water samples will be collected and analyzed for nitrate-nitrogen. Installations were completed in 2015-2016.
The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
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.
