This case study reviews an Underground Storage Tank (UST) case with the State of Arizona Department of Environmental Quality (ADEQ) that had been active for over 30 years. Antea Group®, a leading global environmental consulting firm, developed a remediation plan for in situ soil mixing using RegenOx® and ORC Advanced® in the most highly contaminated zone and in situ chemical oxidation (ISCO) injections using PersulfOx® elsewhere in the plume. The solution using REGENESIS technologies achieved site closure with ADEQ.
Case study highlights:
- Treatment approach demonstrated that the plume was decreasing and not a threat to impact drinking water, prompting the ADEQ to grant closure
- This combined remedy method was 50-70% faster than a thermal treatment approach
- The highly successful approach is estimated to have saved the project over $500,000 compared to remedial alternatives
