Show more [+] Less [-]Dynamic Underground Stripping (DUS) with Hydrous Pyrolysis Oxidation (HPO) Technology was demonstrated using a single well in a trichloroethene (TCE) and tetrachloroethene (PCE) plume at Beale Air Force Base. The performance of the demonstration technology was evaluated to determine the efficiency of TCE/PCE reduction using a single well with HPO process. Primary COC levels were observed for considerable declining trends in the monitoring wells installed in the treatment zone, with up to 85% decline in TCE levels and up to 91% decline in PCE levels. Additionally, the economic analysis showed that single well steam injection/extraction has the potential to be more cost-effective over a conventional treatment, such as pump-and-treat technology.
