W. Va. chemical spill: 'Public health officials differ on water use'
February 6, 2014 - Ben Klein
From David Gutman at the Charleston Gazette:
"State officials have repeatedly said that water is safe to use even if it still has the telltale licorice odor of the coal-cleaning chemical Crude MCHM, which leaked into the Elk River in early January.
The federal Centers for Disease Control and Prevention have said that water is safe for everyone but pregnant women if it has less than 1 part per million of MCHM. But the level at which people can smell the chemical is, according to some studies, 1 part per billion, 1,000 times lower than the CDC's standard.
That divergence is one reason why so many continue to mistrust the water, despite official assertions."
