New lawsuits allege two major Connecticut water companies knowingly provided their customers with unsafe drinking water.

The companies said they’ve notified customers and point to a lack of federal regulations.

It’s public knowledge that water sources in dozens of Connecticut municipalities served by Aquarion and Connecticut Water contain toxic chemicals known as PFAS.

These are called “forever chemicals” because the CDC notes they do not break down naturally in the environment.

The lawsuits allege these companies didn’t do enough to keep customers safe.

Ian Sloss, from the Silver Golub & Teitell, said the companies’ inaction in light of test results are inexcusable.

In addition to monetary damages, they want preventative action.

“We are seeking to have these companies install filtration systems at their water treatment facilities. They’re very available. I won’t sugarcoat it, they are expensive,” said Sloss.

The chemicals, present in firefighting foam, nonstick cookware and water-resistant fabrics, have been linked to increased cancer risks and other impacts. Plaintiffs also seek a medical monitoring program.

In statements, Aquarion and Connecticut Water say they’ve tested their water since 2019 and made the results known. They further note there are no active enforceable treatment standards in the state or nationwide, just guidelines.

“In the same way they're not enforceable, they’re not a ‘get out of jail free’ card,” said Sloss.

The Environmental Protection Agency has proposed a national standard for these chemicals in water, they hope to finalize it later this year.
