Abstract:

This report discusses the installation of a 500 ft mulch wall to remediate chlorinated hydrocarbon-impacted groundwater west of Building 301 at Offutt Air Force Base, Nebraska. The mulch wall was configured to extend southward approximately 400 feet from the existing pilot mulch wall to capture the complete width of the plume. The mulch wall was filled with coarse sand mixed with mulch produced at the Base. The mulch wall was designed to act as a permeable reactive wall, containing a slow-release long-lasting source of electron donor. The organic matter in the mulch ferments, producing hydrogen that can be used to stimulate reductive dechlorination of chlorinated hydrocarbons in groundwater passing through the wall.
