An interagency workgroup is developing recommendations for best practices and policies for water reuse in Minnesota. Recommendations will include both regulatory and non-regulatory approaches to successful implementation of water reuse. The workgroup will evaluate current regulations, practices, and barriers, and quantify and determine acceptable health risks associated with water reuse applications. The University of Minnesota is collecting and analyzing field data for use in targeting Minnesota-specific risks.
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.
Appropriations from the Clean Water Fund allow the Minnesota Department of Health to expand and improve the way groundwater and drinking water protection is implemented at the local level. In 2015, $300,000 was allocated to update wellhead protection areas within groundwater management areas. From 2016 onward, funding will be dedicated to the Groundwater Restoration and Protection Strategies (GRAPS) initiative which will provide groundwater and drinking water information and management strategies on a HUC 8 watershed scale.
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.
