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 Lake Superior Beach Monitoring and Notification Program exists to test recreational beach water and notify the public if bacteria levels become unsafe. This project will expand the Beach Program to include additional outreach efforts, sanitary surveys and testing of new technologies to improve the Beach Program. Monitoring results will be used to inform the public, find the sources of bacterial contamination and address polluted runoff from improper waste disposal.
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.
