How come the taste of my water changes from time to time?
The minerals in a water supply affect the taste of the water, just like different brands of bottled water will taste different. Livermore Municipal Water receives all of its water supply from the Zone 7 Water Agency, the Valley’s water wholesaler. Zone 7 treats water from the State Water Project in the Sacramento-San Joaquin Delta, and from groundwater wells in Pleasanton. As part of managing these potable (safe to drink) water sources, Zone 7 will vary the mix of treated surface water and disinfected well water delivered to the retail water agencies in the Valley. Over the course of a year, Livermore Municipal Water receives mostly treated State Water Project water. On occasion, it will receive more groundwater. The variation in the mix of surface water and groundwater delivered to Livermore may result in changes in the taste of the water.
