Soil Washing - CLU-IN

To address Hg detected in the site's soil, excavation of the contaminated areas will be followed by on-site application of a water-based soil washing technology in a mobile treatment plant to remove the contaminant. The washing and screening process separates Hg from the bulk of the soil, and the washing water is recycled.

Fact Sheet A Citizen's Guide to Soil Washing

Soil washing works best when the soil does not contain a large amount of silt or clay. In some cases, soil washing is best applied in combination with other treatment technologies, rather than as a technology by itself. Removal of contaminants can often be improved during the soil washing process by adding chemi- cal additives to the washwater.

Superfund Engineering Issue - US EPA

evaluate soil washing for treating lead-contaminated soils (USEPA 1989b). The purpose of these screening treatability studies, which were conducted under a give set of operating conditions, was to determine if soil washing can reduce the levels of lead contamination in the soil and to examine the partitioning of lead relative to soil particle size.

Lead removal via soil washing and leaching | SpringerLink

A soil-washing circuit, including size and gravity separations, was employed to remove the coarse metallic lead particles, while the leaching was applied to remove fine metallic lead particles and other lead species. The soil-washing tests proved that the metallic lead particles larger than 0.15 mm (100 mesh) could be effectively removed.

You should be aware, however, that total soil lead concentrations are not always a good measure of the portion of lead that can cause harm. It’s very hard to show that lead in soil is the reason children have elevated blood lead. Other factors, such as lead paint in older homes and dust, can have much bigger impacts.
