A new report says some Kentuckians could be drinking a cancer-causing chemical called chromium-6.
The Environmental Working Group, a public health advocacy group, analyzed data collected from samples of drinking water from all 50 states by the Environmental Protection Agency. Of the 85 Kentucky counties tested, the highest levels of chromium-6 were found in the samples from Daviess County.
The average level of chromium-6 found in Daviess County was 1.12 parts per billion, which according to Bill Walker, EWG managing editor, equates to a drop of water in an Olympic-sized swimming pool.
The EPA has imposed a limit for chromium of 100 parts per billion. But that includes both chromium-6 and chromium-3. The latter is an essential element for human function. However, too much can cause skin rashes.
Walker said the EPA bases its limit on the toxicity of chromium-3, not the more dangerous chromium-6.
“It’s two things mixed together and dumped into drinking water, and EPA says we have a standard to cover the combination of these things,” Walker said. “But don’t have a standard for the individual one, which happens to be more dangerous.
