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 goal of this project is to continue and finalize Hydrological Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process for the Minnesota River–Headwaters and Lac qui Parle watersheds that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) reports.
The goal of this project is to develop a Watershed Restoration and Protection Plan (WRAPS) to be used at the local level. It will increase the number of citizens participating in education and outreach events; foster information and idea exchange around watershed issues through relationships and social networks; involve community members in crafting civic engagement activities/plans in which they feel ownership and desire to implement; and promote awareness, concern, and watershed stewardship to community organizations/institutions.
This project supports monitoring and assessment activities by MPCA EAO 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.
The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during 2016, 2017, 2018 and 2019. There will also be 5 sites in the Red River Basin where mercury samples will be collected in 2016 and 2017 and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
