What depths of contamination need to be evaluated for a construction worker scenario?
Construction workers would be expected to be exposed to both surface (0-2 feet below ground surface (bgs)) and subsurface (2-10 feet bgs) soil. Therefore, it is appropriate to evaluate construction worker exposure to both surface and subsurface soils. If cleanup levels protective of construction workers are lower than those for other surface soil receptors, the lower cleanup levels would also apply to surface soil.
