Central Sierra Domestic-Supply Groundwater Quality

The Central Sierra domestic-supply aquifer study unit focuses on domestic wells located in select California Groundwater Units along the Western slope of the Sierra Nevada Mountains.

Sampling will occur from October 2023 to January 2024.

The GAMA-PBP has done multiple assessments of public and domestic-supply wells in the Sierra Nevada Mountains. Results of the public-supply well assessment studies are available here and here, while more recent domestic-supply well assessment study results are available here.
