Welcome to the United States Geological Survey (USGS) San Diego Hydrogeology project website, which provides geologic and hydrologic information for the transboundary San Diego–Tijuana area, USA and Mexico. This website provides background information about the project; a variety of news items; a large amount of data, in particular for USGS multiple-depth, monitoring-well sites; geologic and hydrologic models; and additional resources including photos, illustrations, and references. Last updated: April 2016

Some additional data may be available from the USGS database National Water Information System (NWIS).

Recent Publication

In 2001, local water agencies and the United States Geological Survey (USGS) began a comprehensive geologic, hydrologic, and geochemical investigation of the groundwater resources in the coastal San Diego area (https://ca.water.usgs.gov/sandiego). The article presents the geochemical approach used in the study to determine the sources and movement of saline groundwater in the San Diego coastal aquifer. These findings are aiding local water managers in mapping the subsurface, in developing a conceptual hydrogeologic framework, and in planning for additional desalination of brackish groundwater.
