Abstract:

A thermal conductive heating TCH pilot test was conducted at the Naval Air Warfare Center NAWC in West Trenton, New Jersey in 2009 in collaboration with TerraTherm, Inc., the Naval Facilities Engineering Services Center and the United States Geological Survey. The NAWC site was historically used as a jet engine testing facility from the mid-1950s to the late 1990s. During this time, the subsurface was contaminated with trichloroethylene TCE which was a common solvent used at the facility. The pilot test consisted of 15 heaterextraction wells installed to a depth of 16.8 m in weathered mudstone and operated for 102 days. Rock core samples were taken pre- and post-remediation to measure the initial TCE concentrations and evaluate the effect the TCH pilot test had. The data collected during the pilot test was used to create a two-dimensional 2D finite difference model using TMVOC. TMVOC is part of the TOUGH 2 family of codes and is a numerical model that is capable of simulating multiphase flow, heat transfer and transport of volatile organic compounds in three-dimensional heterogenous porous media or fractured rock.
