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 objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
This project will assist in assessing the quality of the Mississippi River bordering with Wisconsin in partnership with the Minnesota DNR (MNDNR), the Wisconsin DNR (WIDNR) and the Metropolitan Council of Environmental Services (MCES). Sampling will be conducted in 2016 using water chemistry and biological indicators, using a 5 state strategy recently developed recently with the leadership of the Upper Mississippi River Basin Association. The Minnesota entities will focus their work on the River from St Anthony Falls to the Chippewa River confluence in Lake Pepin.
This project supports monitoring and assessment activities by Minnesota Pollution Control Agency (MPCA) Environmental Outcomes staff and includes lab analysis, equipment, and fieldwork expenses associated with monitoring and assessment activities within the described priority watersheds. Lake Monitoring: Lakes are monitored for nutrients, clarity and other information to provide the data needed to assess the aquatic recreation use support. Biological and Water Chemistry Stream Monitoring: Monitoring to assess the conditions of streams in each watershed.
This project supports monitoring and assessment activities by Minnesota Pollution Control Agency (MPCA) Environmental Outcomes staff and includes lab analysis, equipment, fieldwork, data management, and interpretation expenses associated with monitoring and assessment activities. The ambient groundwater monitoring network describes the current condition and trends in Minnesota's groundwater quality.
The Minnesota Pollution Control Agency (MPCA) uses a watershed-oriented approach to assess surface water quality and define restoration and protection measures. Each of Minnesota's 81 major watersheds is assessed intensively every 10 years, based on a staggered schedule that addresses, on average, eight watersheds per year. To increase the amount of data directly available to the public online, and to make internal operations more efficient, the MPCA started a multi-year Watershed Data Integration Project (WDIP).
This project supports activities by Minnesota Pollution Control (MPCA) Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting Total Maximum Daily Load (TMDL) studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
Staffing support to evaluate the performance of existing stormwater infiltration sites, as identified in the Minimal Impact Design Standards (MIDS) project. Monitor the range of existing infiltration devices in Minnesota and compare to design criteria, maintenance records, and quantify year-round infiltration rates. Develop and refine pretreatment options and standards for municipal stormwater treatment.
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.
Cognizant to the needs of the stormwater community, a group that has engaged in stormwater research at the University of Minnesota (UMN) has developed a research program for the biennium that addresses pressing needs: a stormwater research roadmap and framework for priority needs, research required to improve stormwater pond maintenance, and information transfer related to these needs.
