YES! Under the Safe Drinking Water Act (SDWA), the U.S. Environmental Protection Agency (EPA) sets standards for drinking water quality and the Minnesota Department of Health (MDH) enforces these drinking water standards for public water supplies. The treatment systems for both cities are designed to treat for VOC contamination associated with the Highway 100 and County Road 3 Groundwater Plume Site.
In addition to the federal SDWA, MDH has Health Risk Limits (HRLs) and Health Based Values (HBVs) that are used as guidance values for public drinking water supplies. HRLs and HBVs may be more stringent than federal SDWA levels.
The Minnesota Pollution Control Agency has worked with both cities to design treatment plants to clean the drinking water to meet these more stringent values.
