GAMA Public-supply Well (Deep Aquifer) Assessment Study Units

The GAMA program is a comprehensive assessment of statewide groundwater quality. The program is designed to help better understand and identify risks to groundwater resources. Groundwater is sampled at many locations across California in order to characterize its constituents and identify trends in groundwater quality. The results of these tests provide information for water agencies to address a variety of issues ranging in scale from local water supply to statewide resource management.
