Windrow Composting
At the time this project was done, composting was an innovative technology. Umatilla was the first full scale application of explosives composting in the U.S., SUBASE Bangor was second. Since that time, it has surpassed incineration as the most commonly used method to treat explosives contaminated soil, with about 8 or 9 full scale applications.

Other Technologies Used
There are several other technologies used at Umatilla, including 1) solidification/ stabilization of mixed metals and explosives in soils and 2) on-site analytical methods for explosives in soil and groundwater that are significant from a cost and performance standpoint. These are highlighted in the BRAC Success Story publication.
