Earlier this month the Environmental Working Group (EWG), a non-profit environmental company, released its 2021 Tapwater Database.

"If you've ever wondered what's actually in your tap water, we have answers. Our Tap Water Database provides insight into pollutants in local water resources," Environmental Working Group states.

According to the EWG contaminates like Arsenic, Bromodichloromethane Chromium, Chloroform, Dibromochloromethane, Dichloroacetic acid, Haloacetic acids, Nitrate, Perfluorooctanoic acid, Radium and Total trihalomethanes found in some water can cause cancer.

Hudson Valley Post examined water supplies across the Hudson Valley as well as large water supplies across New York. Below are potentially cancer-causing chemicals found in water, according to the EWG.

Hudson Valley Post only examined big water supplies in the Hudson Valley and across the state. If your local water supply wasn't listed CLICK HERE.

If you are concerned with your water supply the EWG suggests CLICKING HERE to find out what to ask your elected official.

"One of the best ways to push for cleaner water is to hold accountable the elected officials who have a say in water quality – from city hall and the state legislature to Congress all the way to the Oval Office – by asking questions and demanding answers," the EWG states.
