EM PFAS - Surface Water and Fish Tissue Sampling

PFAS monitoring locations and results in Wisconsin DNR's Surface Water Integrated Monitoring System (SWIMS) are presented on this layer. These locations and results are part of a multi-year, statewide monitoring project conducted by the DNR's Water Quality Program, in cooperation with the Fisheries Management Program and other partners, to sample fish tissue and water chemistry at select sites around the state to aid development of PFAS water quality standards, characterize background PFAS concentrations in major water bodies, and describe PFAS concentrations near known or suspected sources of PFAS.
