Although last week's test on the American tap water by chemists claims to have detected the sex hormone estradiol -- found such vertebrate animals as birds, reptiles, and fish -- a more recent test conducted by the American Waterworks Association Research Foundation, says that San Francisco's "best tasting" H20 has come up sparkling clean.

The Gate reports that our tap water, which is really quite tasty compared to, say, the waters of Southern California or elsewhere, has traces of neither pharmaceuticals nor chemical solvents that were previously reported. It seems that "[t]he mistake apparently resulted from confusion over the waterworks foundation's laboratory test results conveyed by the San Francisco Public Utilities Commission to the Associated Press."

This should come as no surprise to Bay Area residents. It's not shocking that most of us are shocked after our first taste from the tap here. While most cities and states have to drink treated water, San Francisco has "bragging rights over pure Hetch Hetchy Reservoir water surrounded by nearly 500 square miles of Yosemite Valley wilderness." Snap.
