TapWaterMap

The EPA's own data, translated

Your city's tap water, in plain English.

Search for your city and you usually get one of two things: an alarming blog or a dense government PDF. TapWaterMap is the calm middle — the EPA's own drinking-water records, translated into plain English, with the source shown every time. No fear, no sales pitch.
