2014-6-30 Soil Washing - Overview Soil Washing is a technology where by liquids such as water (sometimes combined with chemical additives) and a mechanical process are used to "scrub" soils. The scrubbing removes the bulk of the hazardous contaminants from the larger coarser soils and concentrates them into a smaller volume.

Soil Washing - CLU-IN
The soil washing process achieved contaminant removal below targeted levels in 95% of the soil. A traditional remediation strategy would have involved airlifting contaminated soil to the mainland and trucking it to a landfill, whereas the innovative approach allowed for 95% of the soil to be remediated and left on site, with only a small volume ...
