Abstract : Previous Field demonstrations conducted by the U.S. Army Environmental Center (USAEC)have shown that composting can he an effective bioremediation technology for explosives - contaminated soils. Finished compost exhibits extensive reductions in extractable explosives as well as in toxicity compared to the siting materials. USAEC has now conducted testing to evaluate potential long-term changes in compost characteristics, such as my result following redisposal of finished compost. Finished compost form a previous field demonstration was analyzed for extractable explosives, leachable explosives and TNT intermediates (wing USEPA's Multiple Extraction Procedure), and extractable nitratelnitrite. Low levels of extractable explosives were observed in resampled compost consistent with samples from the end of the compost operation. Extractable explosives in the Multiple Extraction Procedure generally declined with successive extractions. As would he expected for organic compost material, detectable nitrate/nitrite concentrations were present in all samples.
