Orange County’s pure drinking water comes from filtered sewage
Whenever I visit my hometown of Orange County, California, I get to sip some of the purest drinking water in the US. The quality is sometimes hard to spot, since many drinking-water contaminants are odorless, tasteless, and invisible to the human eye. Even in cities where the water is contaminated with lead, residents have reported that their taps are crystal clear. But in Orange County, the water is actually as clean as it looks.
