A Windsor family contacted environmental officials after they said they saw firefighting foam building up in their backyard brook.
Connecticut health officials issued an alert immediately following a deadly vintage plane crash on Wednesday where the firefighting foam with PFAS may have made its way into the Farmington River and surrounding waterways.
Currently, state and local officials said they are reviewing samples to determine if the toxic chemical is in the water.
Residents are strongly discouraged from touching the foam or fishing in the Farmington River.
Sunday, Channel 3 spoke with a Windsor resident who said the foam has encroached on her property in Windsor.
Paddy Abramowicz told Channel 3 her backyard brook, Rainbow Brook, feeds into the Farmington River, and on Saturday, she said she noticed foam bubbling over.
