Approximately 1,400 cubic yards of unsaturated soil at a former Wisconsin manufacturing facility contained TCE with PID readings of 2,900 ppm, visible free product, strong solvent odors, and TCLP TCE concentrations of 10 mg/L. Non-hazardous waste classification was required for off-site landfill disposal.
A two-phase ex-situ treatment was executed using an excavator: Fenton’s Reagent was first applied and mixed to oxidize TCE, followed by incorporation of 8–10 cubic yards of BAM per batch. The sequential treatment was applied over a three-day stabilization period, ensuring thorough distribution throughout all soil batches.
TCLP TCE was reduced from 10 mg/L to 0.1 mg/L—a 99% reduction—across the approximately 1,400 cubic yards of TCE-contaminated unsaturated soil at the former Wisconsin manufacturing facility. This result met the non-hazardous waste classification threshold required for off-site landfill disposal, eliminating the need for more costly hazardous waste disposal options. The sequential two-phase ex-situ treatment—Fenton’s Reagent followed by BAM incorporation—was applied over a three-day stabilization period, with seven quality control samples confirming consistent results throughout the treated soil volume. Local landfill disposal approval was subsequently obtained for all treated material.
