Every state has people who get their drinking water from a private well. While private well users are responsible for regularly testing their well water and ensuring it is safe for their household to drink, very few households have tested their well water within the last few years. Minnesota Department of Health conducted a survey with private well users that identified key supports and barriers to testing well water. This session will highlight survey results and describe how those results informed a robust, interdisciplinary, and effective outreach effort to private well users.
