waterStrider Performance for Mine Remediation
Giant Mine
NWT, Canada
Problem: Arsenic-containing dust has contaminated soil and water at the former mine site. The current treatment approach involves permanently freezing dewatered arsenic solids, a costly solution.
Solution: waterStrider offers a cost-effective way to remove arsenic from soil and water, transforming it into a chemically stable, non-leachable waste solid. A simple water wash of arsenic-contaminated soil produced non-leachable material, making it safe for return to the site.
waterStrider’s technologies removed 99.6% of dissolved arsenic from the wash water. The resulting solid waste by-product was easily dewatered and non-leachable, eliminating the risk of arsenic toxicity to the environment.
