In this episode, we return to French Island to learn more about how local drinking water was contaminated through the use of firefighting foam made from PFAS. We meet Mike Jorgenson, a retired firefighter and French Island resident, who explains how firefighting foam was used at the La Crosse airport for routine training and in emergency situations like plane crashes. We also learn how local residents are engaging directly with government officials to advocate for new environmental health protections, including a statewide groundwater quality standard for PFAS.
