US ARMY Camp Bonneville RAU-2C

Facility Site ID: 475000 Cleanup Site ID: 861

Site Background

RAU-2C consists of explosive chemical and percholorate contamination at a landfill area called Landfill 4/Demolition 1 that was also used to burn or detonate ammunition. Explosive chemicals, such as RDX and perchlorate, were found present in the soil and groundwater in this area.

For cleanup purposes, Camp Bonneville has been divided into five remedial action units (RAU). These units are primarily grouped by the nature of the particular release, not by physical boundaries. Click here for information about the full site and other RAUs. 

Site Status

Cleanup of RAU-2C is in progress.

  • In 1997, based on initial site investigations and archive searches, the Army identified releases and threatened releases of hazardous substances Landfill Area 4/Demolition Area 1, the area comprising RAU 2C.
  • In 2005, the Army conducted an interim cleanup action to remove contaminated soil.
  • Groundwater investigations are continuing on a quarterly basis.
  • A Remedial Investigation/Feasibility Study (RI/FS) Report and CAP/Long-term Monitoring Plan with Contingency Plan will be prepared and submitted for public comment.
