What is the EPA standard for lead in high-contact soil?

For lead hazards in soil, inspectors use a target threshold for high-contact outdoor soil. The EPA sets 400 parts per million as the action level for soil in areas where children are likely to have frequent bare-soil contact, such as play areas in a yard. If a soil sample from these areas reaches or exceeds 400 ppm, it’s considered a lead hazard and remediation is advised to reduce exposure. The other numbers aren’t the standard trigger for high-contact soil in this context—they fall outside the commonly cited threshold for play areas or apply to different situations.
