"A Halliburton Co. subsidiary provided water to U.S. troops at a camp in Iraq that was twice as contaminated as water from the Euphrates River, former employees of the company said on Monday.
The subsidiary, Kellogg Brown and Root, also blocked employees' attempts to inform the U.S. military at Camp Junction City in Ramadi that the water was foul or tell them that water tanks should immediately be chlorinated, the workers said."
I don't know why they were expecting anything else from a company named "Brown and Root".
