What is the action level for lead in soil high contact areas?

The action level for lead in soil high contact areas is indeed 400 ppm (parts per million). This standard is crucial for ensuring public health and safety, particularly for children who are more vulnerable to lead exposure due to their behaviors, such as playing on the ground. Soil in high contact areas, such as playgrounds, yards, and school grounds, is subject to closer scrutiny because these are places where individuals, especially children, frequently interact with the soil.

If lead levels exceed 400 ppm, it may necessitate remediation actions to minimize exposure risks and protect public health. Understanding this action level helps in assessing the potential risk in environments where lead contamination might pose health threats, allowing for appropriate interventions to be organized to reduce exposure.
