US drinking water is drugged. Shane Snyder and his colleagues at the Southern Nevada Water Authority in Las Vegas tested the water at 19 treatment facilities across the nation for a selection of compounds that disrupt body function, including pharmaceuticals.

Of the 51 compounds the team tested for, 34 were detected in at least one sample, although none at levels deemed unsafe. The herbicide atrazine and the drugs meprobamate and phenytoin were present in more than half of the samples collected from tap water distributed to homes and businesses.
