Dakota County reveals alarming PFAS contamination in private wells

Dakota County, Minnesota, has released new data on PFAS contamination in private drinking wells. The county has tested 114 wells since 2018, with the majority showing traces of the chemicals. A new online dashboard now displays the results for public viewing. Since 2018, Dakota County has been testing private drinking wells for PFAS, also known as 'forever chemicals'. Out of 114 tested, 94 contained PFAS, with some levels exceeding state and federal guidelines. All 27 environmental wells checked also showed signs of the chemicals.

The county has shared its findings with the Minnesota Department of Health and the Minnesota Pollution Control Agency. These agencies are using the data to support PFAS remediation efforts across the state. A new online dashboard highlights the three most concerning types of PFAS, making the information more accessible.

For those with concerns, Dakota County recommends using a granulated activated carbon filter. Janet Frandrup, a farmer in rural Hastings, found elevated PFAS in her well, but her home’s reverse osmosis system effectively removes the chemicals. Valeria Neppl, the groundwater protection unit supervisor, noted that while the data has been public for years, the dashboard simplifies access. The Minnesota Department of Health already tracks PFAS in community water systems, with over 20 requiring treatment for elevated levels. Dakota County’s new dashboard adds clarity for private well owners. Residents can now check contamination levels and take recommended steps to address concerns.
