HARTFORD, Conn. (WTIC Radio)—The state's Department of Public Health removed a consumption advisory for fish caught from the lower section of the Farmington River Tuesday after seeing a significant decline in levels of a harmful substance.
Recent tests results of fish tissue samples revealed more than 71% of per- and polyfluorinated alkyl substances or PFAS levels had decreased from samples taken in September 2019, officials said in a statement.
After several rounds of sampling, the latest samples measured 18 ppb (parts per billion) which officials say is below the 20 ppb cutoff point for unlimited consumption in Connecticut's consumption advisory guidelines for PFAS in fish.
The advisory was put in place in June of 2019 after a spill of about 20-thousand gallons of Aqueous Film Forming Foam (AFFF) entered the river from the Signature Flight Hangar at Bradley International Airport.
The foam contained PFAS and, according to officials, the advisory was put into effect due to elevated levels of PFAS collected in fish tissue samples.
"The most recent fish samples were collected in July 2020 from the Farmington River downstream of the MDC Poquonock Waste Water Facility where the AFFF was discharged into the river," officials said.
Long-term exposure to PFAS may be associated with increased cholesterol levels, development effects and an increased chance of cancer, among other health issues.
