Nine discrete treatment areas at a large military fuel depot in San Pedro, California contained petroleum hydrocarbons, tarry sludge residuals, LNAPL, and unexpected PFAS and TBA contamination in a highly variable subsurface of sands, silts, and clays. The project required sustained thermal performance across more than 1,600 days of operations while adapting to unexpected contaminants and geological variability between areas.
An adaptive, phased thermal remediation program combined ET-DSP™ and SEE with enhanced extraction systems, robust vapor and liquid treatment infrastructure, and continuous engineering optimization. Each of the nine treatment areas was managed as a distinct sub-project with individually tailored heating strategies and performance monitoring.
Over 350,000 lbs of contaminants and more than 1,132,000 lbs of tarry sludge were removed across the nine treatment areas at the large military fuel depot in San Pedro, California. Heating uptime exceeded 99% and system uptime exceeded 91% over more than 1,600 days of operations. Average subsurface temperatures reached 211°F across all treatment areas. The adaptive phased program successfully managed unexpected PFAS and TBA contamination discovered during operations in addition to the planned petroleum hydrocarbon, tarry sludge residual, and LNAPL targets. Each of the nine treatment areas was managed with individually tailored heating strategies, demonstrating the scalability of combined ET-DSP and SEE thermal technologies at large, multi-area fuel depot sites.
