The Turlock Basin is a sub-basin of the San Joaquin Valley groundwater basin which occupies approximately 13,700 total square miles, making it the largest groundwater basin in California. This aquifer is located within the Central Valley. Groundwater in the San Joaquin Valley occurs mostly in younger alluvial material. The Turlock Basin lies to the east of the city of Turlock. Groundwater in the Turlock Basin occurs in older alluvial deposits. Large portions of the San Joaquin Basin have experienced overdraft of water and infiltration of agricultural water pollutants, resulting in poor water quality.[1]

The City of Turlock receives its entire water supply for domestic use from groundwater. The character of the water is generally a sodium sulfate type,[2] and some local wells have been historically closed due to DBCP pesticide poisoning.
