UST - Depth to groundwater database

"Caution: These data posted here are merely a summary of reports by the responsible party(ies) of each respective site. Regional Board has not verified this information. The depth to groundwater listed is usually the first layer of water encountered underneath the site. The depth varies seasonally over time. In addition, a certain depth at an individual site is not necessarily an indicator to the areawide or regional depth to groundwater. We encourage the users to review the entire report(s) for each individual site to obtain complete information regarding the depth to groundwater and hydrogeology at the site. Please consult a professional for interpretation of the data as needed."
