"Regulations Might Be Needed for 104 Chemicals Found in Tap Water, EPA Says"
"U.S. EPA has found 104 chemicals that might require regulations to keep them out of tap water -- the longest list of potential contaminants ever compiled by the agency.
A 1996 law requires EPA to evaluate possible tap-water pollutants every five years and make regulatory determinations for at least five of them.
The new list -- the agency's third -- includes pesticides, commercial chemicals, disinfection byproducts and, for the first time, pharmaceuticals."Source: Greenwire, 09/24/2009
