Drinking Water Contamination
Due to the Safe Drinking Water Act (SDWA), America's drinking water is safer than it has been in decades, and of better quality than that of many other countries. Accordingly, many Americans believe that while people elsewhere may have reason to be concerned about getting sick from contaminated tap water, we are safe. Yet, incidents in the United States — such as the outbreak of the microorganism cryptosporidium in Milwaukee's water supply in 1993 that killed more than one hundred people and sickened over 400,000, and lead and pesticide contamination — while not affecting most, threaten the tap water of millions of Americans.

The hazards posed by waterborne lead are especially pernicious. In 1991, the EPA estimated that lead in drinking water harms the health of millions of children, causing more than 560,000 children to exceed the level of concern for blood-lead levels defined by the CDC.[11] (A recent EPA rule regulating lead in drinking water may have reduced this number of children.) ...
