This layer is intended for use in the Wisconsin PFAS Interactive Data Viewer GIS mapping application, use for any other purpose should be done with caution to avoid misuse or misinterpretation of information contained in this layer. Please seek appropriate DNR staff support.PFAS results in Wisconsin DNR's Drinking Water System (DWS) Portal are presented on this layer. The results have been generalized by water system and are classified based on the levels of PFAS detected. Point locations are generalized to PLSS centroids and do not represent well or specific water supply system feature locations.Municipal Water System SamplingResults from municipal or public water supply systems that have sampled drinking water for PFAS. Sampling completed prior to 2022 may not be included on this map. More details about sampling results are on the Drinking Water System Portal.Map locations are shown at the Public Land Survey System section center point for each municipal water system rather than the exact location of the well.PFAS health advisory levels (HALs) and the hazard index (HI) approach are defined by the Wisconsin Department of Health Services (DHS).For more information contact the DNR Drinking and Groundwater Program.
