Los Angeles, under its Pueblo Water Right, has an exclusive right to extract and utilize the entire native safe yield of the San Fernando Basin (ULARAW 2021).

• Los Angeles: 20.8 percent of all delivered water, including recycled water, to valley fill lands of the San Fernando Basin (SFB).

• Burbank: 20.0 percent of all delivered water, including recycled water, to the SFB and its tributary hill and mountain areas.

• Glendale: 20.0 percent of all delivered water, including recycled water, to the SFB and its tributary hill and mountain areas.

Currently, only 11% of the City's water supply comes from the aquifer, with it increasing to 20% during drought years (LADWP 2012). This is largely due to the contamination plaguing the aquifer, and the costs needed to remediate to levels safe for human consumption. 

1) Mayor Eric Garcetti's Green New Deal aims to fund projects to increase Los Angeles County's local water supply by remediating the contaminated groundwater. The goal is to have 71% of Los Angeles' water be locally sourced by 2035, which would provide water to over 800,000 people (Stantec 2025).

2)  The San Fernando Valley region is listed as a Superfund site due to the high levels of Trichloroethylene (TCE). Funding is being secured to advance treatment facilities across multiple cities (LADWP 2021).

3) The Los Angeles Groundwater Replenishment Project (LAGWR) aims to improve groundwater replenishment techniques to add up to 22,000 acre-feet per year of purified water to the San Fernando Basin (LADWP 2021).
