GROUNDWATER MANAGEMENT AND QUALITY TARGETS
E
Optimize production of groundwater by maintaining at least 700,000 AFY baseline groundwater production
F
Metric: Average annual production from new treatment projects, wells brought back online, and new wells (AFY)
Metric: Average annual countywide AFY of groundwater production
G
Increase groundwater recharge and storage by enhancing regional facility recharge by 250,000 AFY
Metric: Average annual countywide AFY of groundwater recharge at existing and future facilities/spreading grounds
Optimize production of groundwater by increasing production in areas overlying impaired groundwater by 17,000 AFY
H
Increase groundwater recharge and storage by increasing decentralized infiltration by 30,000 AFY
Metric: Average annual countywide AFY of groundwater recharge outside of existing and future facilities/spreading grounds
Groundwater basins provide a critical source of local supply along with seasonal and annual storage that can be accessed during drought conditions. The ability to fully maximize groundwater basin potential for both supply and storage can be constrained by water quality regulations, sea level rise, poor water quality, and regulated remediation zones. While groundwater basins are managed in isolation of each other, these shared constraints can benefit from shared solutions. Unused local, impaired (or “stranded”) groundwater is poorer quality water that would require additional relatively cost-ineffective treatment and/or conveyance for beneficial use. Being able to further tap into and use localized areas of impaired groundwater would enhance regional resilience. Additionally, leveraging combined groundwater storage potential through enhanced groundwater recharge of local and imported water would improve local emergency, seasonal, annual, and long-term supply reliability.
