California drought: S.F. wants to add groundwater to tap

Most city spigots, which, since the 1930s, have gushed water from Yosemite’s pristine Hetch Hetchy Reservoir, will start delivering the Sierra supply blended with a splash of local groundwater — by many measures, a far inferior sour

The San Francisco Public Utilities Commission recently began digging in and around Golden Gate Park in hopes of drawing underground flows into the mix within the next two years. The move is designed to increase and diversify the city’s water reserves as California faces its worst drought in a generation.

The local groundwater isn’t nearly as pure as the Sierra runoff, which is considered among the best water in the nation, and it sometimes contains unsavory, if not unhealthy, deposits.

But city officials say not to worry: The underground reserves are sufficiently clean and palatable, and will be blended with Hetch Hetchy water in small doses — between 10 and 15 percent — to assure a negligible change… (more)

Since this was published, we found out that the PUC has already begun to blend the water in all the city neighborhoods. The blend is not limited to the West side as we were told it would be. So, if you are drinking from the tap, you are drinking the blend.
