Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals found in various consumer products, including non-stick cookware, water-repellent clothing, and certain food packaging. Due to their widespread use and environmental persistence, PFAS have been detected in water sources nationwide, including here in Stillwater.
PFAS in Stillwater’s Water
Recent testing revealed that some of Stillwater’s drinking water wells contain PFAS levels exceeding the Environmental Protection Agency’s (EPA) standards. In response, the city promptly deactivated the affected wells to prevent contaminated water from entering the public supply. Currently, no active wells exceed the EPA’s drinking water standards for PFAS.
Health Implications
Exposure to elevated PFAS levels has been associated with various health concerns, such as immune suppression, lower birth weights, increased risk of certain cancers, and thyroid dysfunction. Recognizing these risks, the city is committed to mitigating PFAS contamination to safeguard public health.
City’s Response and Future Plans
To address the contamination, Stillwater is constructing a new PFAS treatment facility at Well #10. This project, initiated in mid-September, is progressing steadily, with completion anticipated by May 2026. The facility will employ advanced treatment technologies to remove PFAS from the water, ensuring it meets safety standards before distribution.
Additionally, the city is collaborating with the Minnesota Pollution Control Agency (MPCA) to investigate potential PFAS sources and assess private wells that might be at risk. This comprehensive approach aims to identify contamination sources and implement effective remediation strategies.
Community Involvement
Residents are encouraged to stay informed about PFAS developments and participate in community discussions. The city provides regular updates and resources to help residents understand the issue and the steps being taken to resolve it.
Ensuring safe drinking water is a shared responsibility. By staying informed and engaged, we can collectively address PFAS contamination and protect the health of our community.
