PCE and TCE contamination in silty clay and gravel overlying limestone bedrock at NASA’s Marshall Space Flight Center in Alabama required treatment in a high-security environment with DNAPL penetration into fractured bedrock, unmarked underground utilities, and strict facility access protocols. The complex geology necessitated an integrated multi-technology thermal approach.
An integrated In-Situ Thermal Remediation (ISTR) system was designed and implemented combining IT-DSP™ (Inductive-Thermal Dynamic Stripping Process), ET-DSP™, and SEE for the first time on a single project. The system was engineered to address the distinct heating requirements of the silty clay overburden and fractured bedrock units across three separate treatment areas.
Uniform heating above 194°F was achieved, with peak temperatures of 220°F. Over 273 days of operation with greater than 99% system uptime, more than 63,016 lbs of VOCs were removed, 22 times more than originally projected. This project marked the first application of all three ISTR methods simultaneously at a single site.
