Groundwater Contamination - Organic Compounds

Project Description:

Feasibility study for the removal of DNAPL from Fractured Rock Using Thermal Conductive Heating (TCH). The study, undertaken in collaboration with Dr. Bernard Kueper in the Department of Civil Engineering at Queen's University, Naval Facilities Engineering Service Center (NFESC) and Terratherm Inc., establishes relationships between temperature, heating duration, and degree of contaminant mass removal for a variety of rock types such that the field application of TCH to fractured bedrock can be properly evaluated and designed, both laboratory testing and numerical modeling. Phase 1, completed in 2008 focused exclusively on the laboratory testing of rock samples obtained from the former Naval Air Warfare Center (NAWC) site in Trenton, NJ to provide data necessary to support proper execution of the field pilot test program.   Phase 2, conducted from late 2008 through 2010, focused on the application of analytical and numerical models. The testing of a number of rock types (limestone, dolostone, sandstone, and shale) provides a critical understanding of the application of TCH across the spectrum of geological conditions encountered at DOD facilities.
