USGS Just Began Drilling Another Deep Multiple-depth Monitoring Well

This is the First in a Series of Updates

Goal is to drill to about 1800 feet depth, collect cuttings and cores, and install 5-6 piezometers at different depths. Followup work will include analysis of the cutting and cores; collection of water-quality data; and outfitting the site to collect real-time groundwater levels and transmit them to the internet. These data along with all other well information will be displayed on this project website. This well, SDCC, is the 9th installed as part of this project.

We will be drilling during the entire month of February. We will drill 7 am to 7 pm, 7 days a week on the southeast corner of the San Diego Country Club, near the corner of West Naples Street and Hilltop Drive in Chula Vista. (map).

Welcome to the United States Geological Survey (USGS) San Diego Hydrogeology (SDH) 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.
