Ever been to Hetch Hetchy?
"Earlier this month, the American Waterworks Association Research Foundation tested 20 of the nation's water systems for compounds typically used in medicines, household cleaners and cosmetics and found San Francisco's water almost alone in being free of contaminants. And blind taste tests have also shown that the city's water tastes as good as, and in some cases better than, bottled water."
SF water comes from Hetch Hetchy, a beautiful resevoir north of Yosemite. After all of the recent reports on pharmaceuticals in the tap water of many areas of the country, it is nice to know that the tap water in San Francisco is still drinkable.
