Approximately 6,000 tons of lead-contaminated soil and sludge were remediated at a former oil refinery and moved off-site. Prior to treatment, the TCLP levels were 6.5 mg/L to 736 mg/L. To remediate the waste, a custom EnviroBlend® product was used at a dosage rate of 2% to 7% by weight. This site is now being used as an open space available for commercial/industrial use.
