(CNN) — You might want to think twice about filling your glass from the sink. There may be cancer-causing products in tap water.
That’s according to a new report from the Environmental Working Group. Researchers say they found 22 carcinogens, including arsenic, uranium and radium, in tap water.
The watchdog group says there may be a health risk even though most tap water meets the legal standards put in place by the federal government.
“The vast majority of community water systems meet legal standards,” said Olga Naidenko, Ph.D., EWG’s vice president for science investigations. “Yet the latest research shows that contaminants present in the water at those concentrations – perfectly legal – can still harm human health.”
The group says water systems with the highest risk tend to serve smaller communities and rely on groundwater.
Consumers concerned about chemicals in their tap water can install a water filter to help reduce their exposure to contaminants.
The study was published Thursday in the journal Heliyon.
