| | Former Manufacturing Facility (Southeastern U.S.) - Provided construction management for the treatment of 30,000 tons of slag and slag-affected soil impacted by lead, cadmium, chromium, and zinc.
- Determined that a low dosage would be effective, which resulted in treatment bulking of less than 2 percent additional weight, saving additional costs for landfilling.
- Treated over 60, 500-ton batches in 5 weeks, and disposed treated soil and slag at a Subtitle D permitted landfill. Material properties encouraged favorable pricing from landfills.
- Treatment was performed at less than 90 percent of budget estimates.

Battery Manufacturer (Illinois) - Remediated 30,000 tons of lead-impacted soil, both in situ with surface mixing and ex situ with a pugmill.
- Used the treated material to construct a surface water diversion berm. This saved the time and expense of hauling the treated material to a Subtitle D landfill.
- Saved the client approximately $600,000.

| Automotive Parts Manufacturer (Indiana) - Remediated 9,000 tons of chromium-impacted soil.
- Reduced the chromium to an immobile form, which avoided RCRA hazardous waste permitting requirements.
- Reduced costs and analytical time by utilizing field screening for determining hexavalent chromium and treatment additive concentrations.
- Saved approximately $500,000 compared to traditional excavation alternatives.
