evaluate soil washing for treating leadcontaminated 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.
reduce emissions of PM and PM10 from sand and gravel processing operations. Controls in use include cyclones wet scrubbers venturi scrubbers and fabric filters. These types of controls are rarely used at construction sand and gravel plants but are more common at industrial sand and gravel processing facilities.
