US ARMY Camp Bonneville RAU-2A
Facility Site ID:
47197
Cleanup Site ID:
3867
Site Background
RAU-2A consists of lead contamination at 21 small arms range areas, and includes cleanup of munitions, lead, and other contaminants.
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-2A is completed.
- In 1997, based on initial site investigations and archive searches, the Army identified releases and threatened releases of hazardous substances at the 21 small arms ranges comprising RAU-2A.
- In November 2001, the Army conducted additional investigations to better define the location and geographic characteristics of the small arms ranges.
- Cleanup of 21 small arms ranges in RAU-2A began in 2008. Based on confirmation soil sampling, the cleanup work has been completed at 19 of the 21 ranges.
- Confirmation soil sampling showed that the 1000-inch rifle and machine gun range (RAU 2A-16) included lead-impacted fill soils.
- In 2009, lead contamination was found outside the boundary of RAU 2A-21.
- In 2012, an Amended Prospective Purchaser Consent Decree, included the 2008 Cleanup Action Plan that directed cleanup of RAU 2A. The Decree requires cleanup be completed at the entire Camp Bonneville Site. In 2017, the existing 2008 Cleanup Action Plan for RAU 2A was amended to address cleanup of lead contaminated soil at two locations, RAU 2A-16 and RAU 2A-21. These changes require partial excavation and/or covering the lead-contaminated soil with a geotextile fabric and one foot of clean soil, depending based on results from lead leach ability tests. These tests will determine the likelihood of lead contamination washing or draining from the soil into ground or surface water. Cleanup 2A-16 and 2A-21 is complete.
- A final site cleanup action plan report for RAU 2 is completed and available online.
Site use restrictions called institutional controls are in effect
Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.
Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
