The County Well Index (CWI) contains well and boring records wells within Minnesota; over 400,000 records. It is the principal source of well construction information and geologic interpretations of well records and also contains soil boring records, mineral exploration test hole records, and scientific/research test hole records.
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.
The objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
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 with the assistance of the Board of Water and Soil Resources protects both public health and groundwater by assuring the proper sealing of unused wells.”
Construct fence around city well #2; Add wellhead protection information on City webpage; Send brochure to property owners about wellhead protection; Send information to property owners within the DWSMA about sealing unused wells
Minnesota Department of Health has been collaborating with cities and other community water suppliers since 1993 to develop and implement source water protection plans. Support from the Clean Water Legacy expands and accelerates the number of water suppliers that can be assisted each year in undertaking protection planning and implementation activities.
