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.
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.
