Officials are responding to a firefighting foam spill at the Farmington River in Windsor on Sunday.
Officials said the foam originated from a sprinkler system malfunction at Bradley International Airport.
CT DEEP, The Department of Public Health and local health officials are investigating the issue.
DEEP is advising the public to avoid the foam they may encounter on the river or river banks. People should also avoid fishing from the Farmington River near Poquonock Avenue and south to where it enters the Connecticut River.
Our news partners at the Hartford Courant report the chemicals in the foam have caused tumors in laboratory animals, according to the EPA. In humans, however, the most consistent findings are increased cholesterol levels.
Officials are evaluating the foam’s impact to the watershed.
