Lead in Soil


Modern building with lead-coated copper sheeting on  exterior wall

Uncontaminated soil contains lead concentrations of less than 50 ppm, but soil lead levels in many urban areas exceed 200 ppm (American Academy of Pediatrics, 1993).

Contaminated soils can contain much higher levels.

EPA has established 400 mg/kg for lead in residential soils as a guidance value that would be protective of public health. This value is for guidance only and is not enforceable.

Physical Plant Services is currently monitoring the lead contamination in soil caused from the lead-coated copper sheeting of this modern building.
