A potentially cancer-causing metal made famous by the movie "Erin Brockovich" has turned up in the tap water of 31 out of 35 American cities tested, according to a study that urges the government to adopt tougher standards for the nation's drinking water.http://www.aolnews.com/2010/12/20/study-probable-carcinogen-found-in-31-us-cities-water-supply/
The Environmental Working Group, an independent, Washington-based research organization, conducted the first nationwide analysis of hexavalent chromium, otherwise known as chromium-6, in drinking water. The substance was regularly used as an industrial chemical until the early 1990s and still appears in some plastics factories. It can also seep into groundwater from natural ores.
The metal has been shown to cause cancer in laboratory animals, and the National Institutes of Health defined it as a "probable carcinogen" in 2008.
The same federal government recently enacted school nutrition legislature encouraging locally grown food in urban areas - - food grown in that same carcinogen laced urban soil and water.
They're so busy regulating things that they don't even notice when their regulations are at cross purposes.
