MADISON (WKOW) — The state is stepping up to help Madison find the source of contamination in some city wells.
The contamination comes from chemicals called PFAS. The man-made chemicals are found in things like non-stick cookware, fast food wrappers and firefighting foam.
They’ve been found in six wells in Madison. The concentrations are low enough so the water is still safe enough to drink.
The two wells with the highest concentrations are Well 15 along East Washington Avenue and Well 16 along Mineral Point Road. Madison Water Utility temporarily shut down Well 15 earlier this year.
On Wednesday, the state Department of Natural Resources (DNR) announced it is hiring an environmental consulting firm to find the source of the contamination in those two wells. It is also spending $30,000 on inventorying former industrial and commercial activities to help determine the PFAS source.
The DNR expects to have results by this summer.
In the future, the DNR may choose to take soil and groundwater samples in the areas near the wells to further identify potential contamination sources.
