By Arjun Walia: Many communities around the world have been successful in removing fluoride from their water supply, but that’s not the only concern. Although fluoride is still a controversial topic within the mainstream, the other chemicals found in drinking water are not. A new study done by United States federal scientists found traces of 18 unregulated contaminants in the drinking water utilities in a nation-wide sampling, the study is expected to be published this year. It was conducted by the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (EPA). (1)(2)(3)
They did it by analyzing single samples of untreated and treated water from 25 U.S utilities that voluntarily participated in the study. A total of 21 contaminates were found, and 18 of them are chemicals that are not regulated under the federal Safe Drinking Water Act.
A research hydrologist with the USGS Dana Kolpin, who participated in the study said that “the good news is the concentrations are generally pretty low.” Personally, I don’t think that there is any good news that comes from the fact that 18 unregulated, unhealthy chemicals were found. Sure, they might be in low concentrations, but human beings drink water every day, constantly for their whole life. Four of these chemicals were metal strontium, the herbicide metolachlor, PFOS and PFOA.
What might be the most disturbing discovery are the perfluorinated chemicals that were found, PFOS and PFOA.
