What is the required action at a soil lead level of 5000 ppm?

At a soil lead level of 5000 ppm, the required action is remediation. This means that significant lead contamination has been identified in the soil, which poses a serious risk to human health, especially for children and pregnant women. Remediation involves removing, cleaning, or containing lead from the affected area to minimize exposure and ensure safety.

The guideline for soil lead levels indicates that when concentrations exceed 400 ppm, remedial actions are generally recommended to protect public health. At 5000 ppm, it is well beyond the threshold that necessitates immediate and effective intervention to address the hazards associated with lead exposure.

Regular monitoring, encapsulation, and taking no action would not adequately address the serious risks tied to such high lead levels in soil, which can lead to long-term health issues if not properly managed. Thus, remediation is the appropriate and necessary step to take in this situation.
