Cost-Effective Treatment To Address PCE At Former Dry Cleaning Site
This case study reviews a former dry cleaning site in an upscale Chicago suburb was contaminated with chlorinated solvents, specifically perchloroethylene. The former dry cleaner location is in a busy commercial area on a major thoroughfare and adjacent to upscale residential townhomes. Various treatments including soil excavation and removal and thermal desorption were considered, but were not feasible because they were too costly and disruptive to businesses and residents.
Case study highlights:
- Soil mixing with PersulfOx cost less than half of the thermal desorption treatment.
- Very aggressive remediation goals were met on a quick timeline.
- One application of PersulfOx was powerful enough to reduce contaminant levels from 18,000 ppm to 150 ppm.
