Stewardship and Management Program

Our groundwater stewardship and management program ensures that local groundwater resources designated for current or future beneficial use are properly managed to prevent overdraft, pollution or contamination.

Groundwater Monitoring and Data Management

The Westside Basin Groundwater Monitoring Program provides information summarizing basin-wide groundwater pumping, groundwater levels and quality in the different aquifer systems within the basin, and surface water conditions, most notably in Lake Merced. The program also monitors physical and chemical changes in the groundwater system resulting from current pumping at the San Francisco Zoo and Golden Gate Park, the proposed San Francisco Groundwater Supply Project wells, the Recycled Water Project, current and proposed recycled water use for irrigation, and the Regional Groundwater Storage and Recovery Program in northern San Mateo County.

The current Annual Monitoring Report is available here.

We are also developing a Well Head Protection Program in the North Westside Basin, to attain the following goals:

• Ensure that areas around production wells are kept clear of potentially hazardous materials.
• Ensure, in collaboration with the SFDPH, that monitoring wells and production wells no longer in use are properly decommissioned to prevent creating potential vertical conduits that could impact groundwater aquifers.
