Western Central Valley Domestic-Supply Groundwater Quality

The Western Central Valley domestic-supply aquifer study unit focuses on domestic wells located in select groundwater basins along the Western edge of the Sacramento and San Joaquin Valley Groundwater Basins (U.S. Geological Survey, 2014).

Sampling will occur from April to July of 2023.

The GAMA-PBP sampled the public-supply aquifer zone of the Western Sacramento Valley between 2005 and 2006 and the Western San Joaquin Valley between 2005 and 2010. That part of the aquifer typically supplies water used for public drinking water. Results of the public-supply well assessment studies are available here, here and here in order to get a sense of the water quality in public-supply aquifers along the Western edge of the Central Valley.
