There were severe Hexavalent and trivalent chromium contamination on this site as a result of waste associated with chromites ore processing. Total chromium ranged from 153 ppm to 12.850 ppm with leachable chromium ranging from 88mg/L to 170 mg/L. A conducted treatability study providing MBS will successfully treat both total and leachable Hexavalent chromium and leachable trivalent chromium, Unlike other technologies, MBS does not require a pre-treatment step to convert Hexavalent chromium to the trivalent form prior to stabilization.

Preceding on-site treatment, material was excavated and screened to 2.5 cm. Treatment results mirrored laboratory tests with the leachable Hexavalent and trivalent chromium reduced to fractional / non-detectable levels.
