Hundreds of millions of Americans, including those in the Channel 11 viewing area, are drinking tap water contaminated with a cancer-causing chemical, a new report shows.
According to the study by the Environmental Working Group, every water system but one in the region were found to have water contaminated by the carcinogenic chemical chromium 6. The tests were conducted between 2013 and 2016.
Currently, the U.S. Environmental Protection Agency has not set a specific limit for safe levels of chromium 6 in drinking water. There is scientific uncertainty regarding possible long-term consequences of ingestion.
Chromium 6 is the same chemical in the real-life case of Erin Brockovich. It's found naturally in things like rocks, animals, plants and soil.
In the new study out of California, 60,000 water samples in all 50 states were taken and 75 percent were found to have higher levels of chromium 6 than what the researchers deemed to be safe.
The only local water system in the study that did not test positive for the chemical was the Tri County Joint Municipal Authority in Washington County.
