Bare Soil - Removal Criteria value?

Bare Soil - Removal Criteria value?

• A. 1200 ppm
• B. 400 ppm
• C. 0 ppm
• D. 5000 ppm

Answer: (D)

Soil action levels for lead depend on how the soil is used and exposed. Bare soil—not in a playground area—has a higher threshold because the likelihood of direct, repeated contact is lower, so the guidance allows more lead in the soil before removal is required. The removal criterion value for bare soil is 5,000 ppm. If soil lead exceeds this level, removal or significant remediation is required; if it’s below, other measures such as stabilization or covering with clean material may be appropriate to control exposure. For context, play areas are typically required to be addressed at much lower levels (around 400 ppm), and general yard soil around the home is often considered at about 1,200 ppm. Always follow current local regulations and project-specific guidelines.
