Basin Notes

2004: Bulletin 118 basin description

2014: CASGEM basin prioritization – very low

2018: Draft basin priority – very low. Comments –

  • 1) CASGEM/WDL/GWIDS: No data or data insufficent to determine GWL status. Source: DWR
  • 2) No available documentation on groundwater level decline past or present in the basin

Salt intrusion –

  • 1) Natural sources of TDS to groundwater in the San Francisco Bay study unit (Marina, Lobos, Downtown, Islais Valley, South San Francisco, Visitacion Valley, Westside, and the Santa Clara Valley groundwater basins) include saltwater intrusion from the Bay and interaction between recharge water and aquifer materials derived from marine or estuarine sediments. On the east side of the Bay, high and moderate concentrations of TDS were detected in areas with a history of intrusion of water from the Bay in response to pumping of freshwater from aquifers. Using surface water–remediated. Source: Groundwater Quality in the San Francisco Bay Groundwater Basins, California, USGS 2012
