Almost half of the tap water in the US is contaminated with chemicals known as “forever chemicals,” according to a new study from the US Geological Survey
. The number of people drinking contaminated water may be even higher than what the study found, however, because the researchers weren’t able to test for all of these per- and polyfluorinated alkyl substances, or
exposure is linked to problems like cancer, obesity, thyroid disease, high cholesterol, decreased fertility, liver damage and hormone suppression, according to the US Environmental Protection Agency. In June 2022, based on the latest science, the EPA issued health advisories that said the chemicals are much more hazardous to human health than scientists originally thought and are probably more dangerous even at levels thousands of times lower than previously believed.
chemical would be detected in 45% of US drinking water samples. Most of the contamination came from water sources near urban areas and in areas that generated can be found in many places, studies show, so toxicologist Dr. Jamie DeWitt is not surprised that it is in so much drinking water. “There’s been almost no place scientists have looked where they have not found
are in mobile phones, commercial airplanes and low-emission vehicles, in the foods you can buy at the farmers market or the grocery store, and in rainwater and dental floss. They’re even in the dust that collects in your home. A 2019 study suggested that are not as easily detectable. “I think that’s still a pretty high number, considering,” she said. DeWitt said that it’s important for people to know what’s in their drinking water but that they don’t necessarily need to be scared. “I don’t think people should be afraid, but they should be aware and armed themselves with knowledge so that they can get information that will help them to make decisions,” she said.
