Elevated levels of PFAS were found, which are commonly put inside household products -- like non-stick cookware.
One father, who wanted to remain anonymous, got emotional once hearing about the news.
He's worried the toxins had an impact on his son's small birth size.
"When I read that paragraph that says there might be birth defects, that sticks out like a huge red flag," he said.
The EPA does not regulate PFAS, which means officials do not test for the chemical.
Authorities acted once a private citizen tested the water, which came back with more than twice the recommended amount.
