Treatment of Lead Contaminated Soils Using EnviroBlend

Treatment of Lead Contaminated Soils at the Former Speakman Company Facility in Wilmington, DE
This project was successfully completed in 2007 and included the treatment of approximately 3,000 tons of soil contaminated with lead sand from the buildings foundry.

The untreated soil contained total lead concentrations in excess of 6,500 ppm. The stabilization material was added at 1 to 3 percent by weight of the treated soil. The treated soil gave an average TCLP value of less than 1 ppm. Treatment production at the project was running in the range of 250-350 tons per day, depending on the weather. The treated soil was transported off site and disposed of at a non-hazardous sub-title D landfill after treatment and new low to moderate income housing was built onsite. This work was conducted in close contact to the Delaware Department of Natural Resources & Environmental Control (DNREC) and DNREC approved the remediation and disposal option upon its completion. This proved to be a technically sound, environmentally acceptable, and cost-effective solution.
