Bioremediation using composting or anaerobic treatment for ordnance-contaminated soils
- Remediation Technologies, Inc., Seattle, WA (United States)
Government installations nationwide are faced with the problem of cleaning up soils contaminated with ordnance compounds. The materials have been introduced into the environment through the manufacture, use, storage, and disposal of explosives such as 2,4,6-trinitrotoluene (TNT), octahydro-1,3,5,7-tetranitro-1-3-5-7-tetraazocine (HMX), and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). The effectiveness of aerobic biological treatment (composting) for the remediation of nitroaromatics-impacted soils has been confirmed in several laboratory and field studies. Composting involves the incubation of contaminated soils with organic amendments under thermophilic conditions (40 to 70 C). Over the last several years, the remediation of nitroaromatics-contaminated soils has been demonstrated using the Simplot Anaerobic Bioremediation (SABRE{trademark}) process developed by the University of Idaho and the J.R. Simplot Company. Both process were proven effective at the bench-scale for the remediation of two ordnance-contaminated soils from a local Naval Installation. This paper presents the results of the pilot-scale testing of these technologies conducted from December 1994 through March 1995 at the Bangor Naval Submarine Base (Silverdale, Washington). Goals of the pilot study were to provide cost and design information for the implementation of the full-scale remediation scheduled for mid 1996.
