The Department of Natural Resources says an experimental technology has failed to keep so-called “forever chemicals” from the Madison airport out of Madison’s lakes and streams, but county officials say they need more time to test it.
In May, after tests showed stormwater from the airport contained high levels of hazardous PFAS compounds, Dane County announced plans to test a system of booms and “bioavailable absorbent media” — also known as BAM — to treat water draining into Starkweather Creek.
In letters sent Thursday to city and county officials, the DNR said the treatment “has not proven to be successful in reducing PFAS concentrations” in water from the outfall.
