Bioaccessible means the lead can be dissolved in the gut and absorbed by the body. According to Ganga Hettiarachchi, a professor of soil and environmental chemistry at Kansas State University, the two most common sources of lead in garden soils are from the past use of leadbased paint and leaded gasoline.

A soilwashing 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 soilwashing tests proved that the metallic lead particles larger than 0.15 mm (100 mesh) could be effectively removed.

Soil washing is an exsitu remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and

Fact Sheet A Citizen''s Guide to Soil Washing nepis.epa.gov

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.
