Environmental Health Services
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.
A few topic-specific guidelines have been developed to provide more up-to-date guidance for responsible parties and consultants. You can view these guidelines in the resource library below. For other issues please refer to the guidance documents below and/or your case manager at 650-372-6200.
Inspection staff also issue permits for installing wells and soil borings for geotechnical or environmental investigations. Staff can answer questions about contaminated sites or provide information on regional underground water supplies.
You can apply for a Subsurface Drilling Permit and Geotechnical Drilling Permit, pay invoices, and manage your permits online using MyEHS.
If you’re unable to apply online with MyEHS, you can download and complete the Subsurface Drilling Permit and Geotechnical Drilling Permit PDF application here (see Downloadable Applications Forms Section).
Payments cannot be made to or accepted by inspectors. Payments must be made in person at the Environmental Health Services office, by mail, by phone at (650) 372-6200, or online through the MyEHS Portal.
