While advocates like Erin Brockovich praise new state standards for cancer-causing chromium 6 in drinking water, an Orange County water official says the regulations go too far, reports PBS SoCaL's David Nazar.
"They may have a little science here, a little science there, but the complete studies I don't think have been completed," said Brett Barbre, a board member at the Municipal Water District of Orange County and one of Orange County's representatives to the Metropolitan Water District of Southern California.
Chromium 6 is often found naturally in the Mojave Desert, and a new private project overseen by South Orange County's Santa Margarita Water District is expected to produce water that exceeds the new state standard for the substance, according to the Los Angeles Times.
MWD officials have said that the water for the Cadiz, Inc. project will be required to be treated before it enters the Colorado River Aqueduct on its way to Orange County and elsewhere.
That treatment could cost between $7.5 million and $20 million each year, based on figures in the Times article.
