Are water vending machines SAFE ?  

California water-vending machines tested last summer failed to meet state standards for chemicals about a third of the time, according to a report by environmentalists. "Buying water from a machine in California is like playing a slot machine: You can't be sure what will come out," said a report released by the Environmental Working Group and the Environmental Law Foundation, which checked 274 machines.

In San Francisco County, only one out of 15 machines met the state standard, the report said. In Santa Clara County, all 15 tested machines hit the mark.

So, mylotters, be careful !
