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 will construct, calibrate, and validate two Hydrologic Simulation Program FORTRAN (HSPF) watershed models. The consultant will produce HSPF models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs) at the Big Fork River and Little Fork River watersheds.
This project is a cooperative effort between Crow Wing and Itasca County to contract with RMB Laboratories to generate 65 lake assessment/trend analysis reports. The watershed protection model is an innovative and proactive approach to water resource management which is geared towards prioritizing areas of concern, targeting implementation strategies, and measuring their effectiveness. These assessments are also useful and understandable tools for lake associations and the public.
The Minnesota Department of Natural Resources will coordinate the collection of high-resolution elevation data for northeastern portion of Minnesota using Light Detection and Ranging (LIDAR) systems. The geographic area of the work includes Minnesota counties of Carlton, Cook, Lake, and St. Louis Counties and that portion of Koochiching County that comprises Voyageurs National Park.
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 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.
