A former manufacturing facility in southeast Michigan presented petroleum-contaminated soil and groundwater (TPH and BTEX) across a 12,000 ft² area. A pilot study was conducted prior to full-scale implementation to validate injection design parameters and optimize chemical distribution.
Full-scale in-situ chemical oxidation was executed over four days using 179 Direct Push Technology (DPT) injection points advanced to 2–12 ft below ground surface. Each point received approximately 170 gallons of 12% calcium polysulfide solution, totaling 30,478 gallons across the treatment zone.
The pilot-validated injection design achieved effective distribution of the 12% calcium polysulfide treatment chemistry throughout the 12,000 ft² treatment area. Over four days of full-scale operations, 30,478 gallons of treatment solution were delivered across 179 Direct Push Technology injection points at depth intervals of 2 to 12 feet below ground surface—approximately 170 gallons per point. The pre-implementation pilot study provided the design parameter validation that allowed the full-scale program to proceed with confidence, and remediation objectives for petroleum hydrocarbon (TPH and BTEX) contamination were met at the former manufacturing facility in southeast Michigan.
