Historical Background

The Titan 1-A Missile Facility was completed in 1962 and housed three 160-foot-deep missile silos and supporting infrastructure. The site was decommissioned in 1968, and portions were sold to private owners and Placer County.

In 1991, contamination was found in the groundwater, which led to several investigations by the USACE. Over the years, various remedial tests have been performed, with efforts continuing under the FUDS program.

In 2018, investigative work resumed, with the installation of monitoring wells and soil vapor probes to regularly assess contamination levels and collect new data.
