So what's in your water? The Environmental Working Group knows:
Drinking water may have a lot more in it than just H20 and fluoride, according to an environmental group's analysis of records in 42 states.
A survey by the Environmental Working Group released on Tuesday found 141 unregulated chemicals and an additional 119 for which the Environmental Protection Agency has set health-based limits. Most common among the chemicals found were disinfection byproducts, nitrates, chloroform, barium, arsenic and copper.
