PFAS Testing of Public Water Systems
MDH has been assessing the potential health impacts of perfluoroalkyl substances (PFAS) in groundwater in Minnesota since 2002. MDH and the Minnesota Pollution Control Agency (MPCA) have a long history of working with people in the East Metro to protect them from the health effects of PFAS in their groundwater. MDH began sampling community water systems (CWSs) for PFAS in 2006. Much of this sampling has taken place in the East Metro and in areas where aqueous film-forming foam (AFFF) was used, such as airports and military bases.
Our PFAS monitoring goal: 90% by 2025
MDH has a long-term goal of sampling all CWSs in Minnesota for PFAS. Under this goal, MDH aims to cover 90% of CWS customers under its PFAS monitoring program by 2025. Through the PFAS monitoring program, MDH will evaluate whether Minnesotans are exposed to PFAS at levels above health-based guidance values in drinking water.
