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 supports monitoring and assessment activities by MPCA EAO 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.
This Initiative is a nine-year plan to take a systematic approach to inventory and analyze all Public Waters within the County. Phase 1 includes identifying areas of concern through GIS analysis of current landuse along Public Waters, and the development of a database of non-compliant landowners which will be updated and maintained. Once landowners have been identified they will receive a joint letter and map stating that they may not be in compliance.
The Douglas County Partners for Clean Water program enables community groups to take action and improve their water resources. Engaging citizens directly in project development and installation efforts provides immediate water quality benefits and cultivates a community of active stewardship.
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.
Todd County Septic Inspectors will research septic systems on 313 parcels that are located in the "highly vulnerable" portion of the City of Long Prairie's Drinking Water Supply Management Area. Each parcel's tanks and soil drain fields will be inspected for septic system compliance. Todd County will follow up with landowners found to have noncompliant systems in an effort to protect Long Prairie''s drinking water supply.
This monitoring work expands on previously established routine water quality and flow sampling to include extensive fish and aquatic invertebrate surveys. Subsequent steps include assessment of the monitoring data to determine impairments, identification of stressors that are causing impairments, development of Total Maximum Daily Load (TMDL) studies using identification of pollutant sources using computer modeling and other techniques, civic engagement, and public education as approaches in progress towards water quality goals.
Locating the sources of sediment, phosphorus, and bacteria is integral to reducing the effect they have on a water body. The completion of the West Fork Des Moines River (WFDMR) Targeting and Prioritizing Endeavor will result in a set of data that is the most cost-effective for the implementation of Best Management Practices (BMPs) for all identified priority resources. The results will be expressed as the maximum reduction of a water quality contaminant (e.g. sediment, phosphorus, bacteria) at a priority resource (e.g. an impaired stream) for a given level of investment.
