Untreated composite of arsenic impacted soil, “average”, soil concentration result was 3,720 mg/kg; untreated “high” arsenic impacted sample was 6,330 mg/kg. Average sample resulted leaching of 18.9 mg/L in TCLP prior to treatment. A dosage rate of 1% wt./wt. EnviroBlend HXD reduced arsenic leachability to 0.69 mg/L. The highly impacted area, untreated sample leached at 50.6 mg/L in TCLP testing. Dosage of 2% wt./wt. met TCLP criteria, and further dosage dropped the concentration of leachable arsenic.
These case studies are examples of the extensive work EnviroBlend has completed across the United States. For more information on our project experience please contact us.
