FREQUENTLY ASKED QUESTIONS Q1: Is there an imminent health risk associated with soils in the defined site area?
A1: The risks associated with these soils would not be considered an “imminent health risk.” However, Federal, State and city/county health agencies all agree that residential soil lead levels over 500 milligrams per kilogram (mg/kg), and residential soil arsenic levels over 46 mg/kg could pose an unacceptable level of risk to children in the 1 to 6 year age range. Children with the greatest degree of hand-to-mouth behavior (1, 2, and 3 year old children) would be at greatest risk.
