"Millions of Americans may be drinking water that is contaminated with dangerous doses of lead. The Environmental Protection Agency (EPA) knows it; state governments know it; local utilities know it. The only people who usually don’t know it are those who are actually drinking the toxic water."
"The problem stems from a common practice in which water utilities replace sections of deteriorating lead service lines rather than the entire lines, commonly known as partial pipe replacements. It is a course of action that can do more harm than good.
'It’s scary and the magnitude of this problem is huge,' said Dr. Jeffrey K. Griffiths, a Tufts University professor of medicine and public health, who recently chaired an expert panel advising the EPA on the problem. 'I didn’t realize how extensive the lead exposure still remained. … EPA is really deeply concerned about this …. This was not something they expected.'"
