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.
Lac qui Parle-Yellow Bank Watershed District will collect water chemistry samples from the three lakes and twenty-nine stream sites in the Lac qui Parle and Minnesota Headwaters watersheds following the MPCA’s Intensive Watershed Monitoring (IWM) plan for lakes and streams. Eleven samples will be collected at each lake from May through September during 2015 and 2016. Eleven samples will be collected at each of the twenty-nine stream sites in 2015. In addition, sixteen samples at each stream site will be collected in 2015 and 2016 following the E.
The goal of this project is to establish a framework that the local government can use to guide their involvement as the UMR Watershed Project progresses over the next four years. This will result in strategies to protect or restore the waters in this watershed. These strategies will be used as the basis for making informed local water quality and land use planning decisions, as well as development of grant applications to implement the restoration and protection of waters in the UMR watershed.
Several important milestones will be completed during this Phase (Phase II) of the Mississippi River (Headwaters) Watershed Restoration and Protection Strategy (WRAPS) project. These milestones will include the completion of the Stressor ID & Watershed Monitoring and Assessment Reports, the completion of the Zonation Modeling watershed priority planning process (through the continuation of the Civic Engagement project component), and the development of the overall WRAPS report.
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.
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.
