A new study shows over 97 million Americans face health risks from unregulated chemicals in their drinking water
Washington: Let this sink in. Over 97 million Americans are drinking water that’s contaminated with toxic chemicals. This new study raises serious concerns about the safety of tap water in the U.S.
The Environmental Protection Agency (EPA) has set limits on over 90 contaminants, but researchers from the Silent Spring Institute found that 27% of the 4,800 public water systems they looked at had at least one harmful chemical that isn’t regulated.
Some of the nasty chemicals they found include 1,4-dioxane, which is a likely carcinogen, and chlorodifluoromethane, a refrigerant that can cause severe health issues. There’s also 1,1-dichloroethane, a cleaning solvent that might increase cancer risks, and the infamous PFAS, known as “forever chemicals.”
These PFAS have been linked to various health problems, including a higher risk of certain cancers. The study used EPA data from 2013 to 2015, and while the EPA is testing again, the results aren’t out yet.
There are over 12,000 types of PFAS, and current tests can’t catch them all. The EPA plans to regulate six types of PFAS in drinking water starting in 2029, which could help reduce exposure for about 100 million people.
It’s worth noting that Hispanic and Black Americans are at a higher risk of exposure because they often live near pollution sources like treatment plants and industrial sites.
The findings were published in the journal Environmental Health Perspectives, and they follow the discovery of a mysterious toxic chemical byproduct in treated drinking water that millions consume.
If you’re worried about your tap water, it’s a good idea to reach out to your local water utility or health department to see if they’ve tested for PFAS and other contaminants.
For home treatment, you can use granular activated carbon filters or reverse osmosis systems. Just make sure to follow the manufacturer’s instructions and replace filters as needed. And be cautious with bottled water, as many companies source from municipal supplies without testing for PFAS.
