What are PFAS? PFAS are a group of human-made chemicals used for decades in numerous products like stain-resistant carpets & fabric; non-stick cookware, firefighting foam, and fast food packaging.

PFAS Sampling

Sun Prairie Utilities is Participating in a Voluntary PFAS Sampling Program

Wisconsin and states nationwide face challenges related to Per- and Polyfluoroalkyl substances (PFAS), which have been manufactured for use in everyday items such as nonstick cookware, water-resistant clothing, and personal care products. PFAS have also been widely used in firefighting foams, in industrial applications, and military installations.

Sun Prairie Utilities is voluntarily participating in the Wisconsin Department of Natural Resources (WI DNR) statewide investigation into the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in drinking water at municipal drinking water suppliers in WI during 2022.  Sun Prairie Utilities voluntary sampling for PFAS allows SPU to proactively assess the potential impacts of PFAS in the drinking water and to quickly take steps to protect the health of our customers if needed.  

Studies have examined possible relationships between levels of PFAS in blood and harmful health effects in people. PFAS persist in the environment and the human body for long periods of time. Recent findings indicate that exposure to certain PFAS may have harmful health effects in people related to health complications like cancers, thyroid problems, heart issues, or reproductive issues like infertility, low birth weight, and developmental delays.

Sun Prairie Utilities anticipates sending samples to the WI State Lab of Hygiene in June and receiving the results approximately one month later. Sample results will be posted by WI DNR at https://dnr.wi.gov/dwsviewer/ as they become available. If PFAS are identified in the drinking water WI DNR will work with Sun Prairie Utilities to ensure the validity of data and identify appropriate response measures, including outreach and communication with customers.
