CDC covered up high lead levels in D.C.

The Raw Story | CDC covered up high lead levels in D.C.: "Eight years ago, engineers and officials in Washington, D.C. decided to give the go-ahead for a program that would eliminate the 'potentially carcinogenic by-products' of chlorine in tap water. The program replaced chlorination with chloramination, and it worked. However, in the next three years, hundreds of families with homes fitted with lead pipes in the District of Columbia were exposed to dangerously high lead levels. Unknown to scientists at the time, the chlorine in tap water served as a 'binder' for the lead pipes, keeping a certain amount of lead from dissolving in the water. In 2004, the chlorination method was restored.
