The Environmental Working Group recently published a 3-year study on tap water quality in 48,000 communities in 45 states and the District of Columbia. One analysis of the report I read indicated that some of the water samples EWG collected for testing was raw water prior to being treated, so it wasn’t water consumed at the tap. It isn’t clear if EWG was aware of that before publishing the report or while testing was being done.

Today Emily Green has gathered together a number of subsequent news stories that make the validity of EWG’s data, as she puts it, “clear as mud.” See her story here.
