AFFF use at the airport has contaminated surrounding groundwater and surface water, affecting nearby municipalities and private wells. The Connecticut River watershed, which provides drinking water to much of the state, requires ongoing monitoring due to multiple upstream contamination sources.
The state's industrial history has created additional PFAS sources, including manufacturing facilities in Hartford, New Haven, and Bridgeport areas. Several water utilities have installed treatment systems to address contamination, while others have closed contaminated wells and developed alternative supplies. Connecticut's dense population and interconnected water systems mean contamination in one area can quickly affect multiple communities.
