Site technology capsule. J.R. Simplot ex-situ bioremediation technology: Dinoseb
The J.R. Simplot Ex-Situ Bioremediation Technology is designed to anaerobically degrade nitroaromatic and energetic compounds in soils and liquids without forming identifiable toxic intermediate compounds produced by other biotreatment methods. This technology was evaluated under the Super-fund Innovative Technology Evaluation (SITE) Program on soils contaminated with 2-sec-butyl-4,6-dinitrophenol (dinoseb), a RCRA-listed herbicide (P020). The Demonstration was performed on 2,4,6-trinitrotoluene (TNT). Comparison of the dinoseb levels before and after treatment showed a reduction of greater than 99.8% based on the analytical instrumentation detection limit. The time of treatment for 30 cubic m (39 cubic yd) of soil was found to be 23 days, much faster than initially anticipated. Other compounds, namely nitroaniline; parathion; malathion; and 4,4`-DDT were incidently and simultaneously reduced from parts-per-million levels in the feed soil to below the analytical detection limit in the treated slurry.
