Groundwater Protection Program


Groundwater Protection Program

The goal of the Groundwater Protection Program is to protect underground water supplies and surface waters, such as the creeks, streams, ocean and the Bay, from chemical pollution.

Information such as reports, workshop slides, and agendas on the San Mateo Plain Sub-Basin groundwater assessment can be found at the Office of Sustainability’s Groundwater website and select San Mateo Plain Sub-Basin.

Inspection staff oversee clean-up of pollution caused by leaking underground tanks and chemical spills. They work with other agencies, such as the Environmental Protection Agency (EPA) and the Water Quality Control Boards, to make sure the clean-up process follows State and local laws.
