Spartanburg Water System is asking customers to educate themselves on Chromium-6, after a recent study says many Upstate water systems have traces of the chemical.
Chromium-6 was widely talked about in 2000 after the release of the movie Erin Brockovich. The full study, can be viewed, here.
For the Upstate counties, the levels are so low, that it is a natural result, according to Spartanburg Water System.
Chromium is an unregulated contaminant, and the EPA requires water systems to test for them every 5 years.
