Connecticut Clean Water Action has led the efforts to restrict toxic chemicals including bisphenols, lead, and PFAS in key product sections. Like other states, Connecticut has concerns about toxic chemicals such as lead and PFAS. For instance, Connecticut has a significant number of older homes and buildings, which increases the risk of lead-based paint hazards. Additionally, firefighting foam containing PFAS was used for many years at the Bradley International Airport in Windsor Locks. A 2019 leak of firefighting foam from a hangar at the airport resulted in 40,000 gallons of foam entering the Farmington River.
