Residents of Stillwater have recently voiced concerns regarding the presence of per- and polyfluoroalkyl substances (PFAS) in the city’s drinking water. PFAS are man-made chemicals used in various consumer products since the 1940s, known for their persistence in the environment and potential health risks.
The City of Stillwater’s water utility serves approximately 20,600 people, drawing from the Prairie Du Chien-Jordan and Jordan aquifers through eight wells. The water undergoes treatment with chlorine and fluoride in accordance with Minnesota Department of Health standards. However, recent findings have indicated elevated levels of PFAS in some of the city’s wells.
In response, the Minnesota Pollution Control Agency (MPCA) has initiated an investigation to identify potential PFAS sources in the area. This includes sampling private wells to assess contamination levels. The MPCA aims to determine the origin of PFAS in Stillwater and plans to conduct water and soil sampling throughout the city. Residents may observe MPCA staff and contractors performing drilling activities on public properties and rights-of-way. Private well owners selected for sampling will receive detailed results, and if PFAS levels exceed health-based guidance values, they will be eligible for treatment provided by the MPCA.
PFAS exposure has been linked to various health concerns, including immune suppression, lower birth weights, increased risk of certain cancers, changes in liver function, and thyroid disease. The City of Stillwater emphasizes its commitment to ensuring safe drinking water for all residents and is collaborating closely with state agencies to address the issue.
Residents with questions or concerns are encouraged to contact the Minnesota Pollution Control Agency or visit the city’s official website for more information on PFAS and ongoing investigation efforts.
