A non-profit organization tested water supplies across the Hudson Valley and New York state and discovered chemicals that could cause cancer.

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.
