(KSTP) – The Minnesota Department of Health (MDH) issued new guidance on drinking water and contaminants on Tuesday morning amid “new scientific research.”

In a news release, the MDH said it’s lowering its health-based values (HBVs) — the acceptable level of contamination in water with no health risk — for two per- and polyfluoroalkyl substances (PFAS) in drinking water.

Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) both contain a level of contaminant that is unhealthy for drinking, according to new research from MDH.

The MDH says people can be exposed to PFAS in a variety of ways, including drinking water and some consumer products.

More information about reducing exposure to PFAS can be found below.
