LA CROSSE, Wis. (WXOW) - Soil samples have shown a high rate of potentially dangerous chemicals in the groundwater around the La Crosse Regional Airport.
PFAS are man-made chemicals commonly found in firefighting foam. Firefighters frequently use the airport grounds to test firefighting tools and tactics.
PFAS can enter groundwater after the use of Aqueous Film Forming Foam (AFFF) on the ground surface. PFAS can travel downstream in groundwater from the location at which the substance contacted the ground surface.
Recent sampling has indicated that low levels of contaminated groundwater may be moving off-site from the airport in a southeasterly direction.
According to the city's website, the DNR is recommending that 70-75 water wells for PFAS. Instead, the city is looking to test anywhere between 120-130 wells to give a better idea of any potential contamination. The city would pay for the testing.
