What is the IDPH regulatory level for lead in soil?

The correct regulatory level for lead in soil, as established by the Illinois Department of Public Health (IDPH), is 1000 parts per million (ppm). This standard is significant because it reflects the threshold at which lead contamination in soil poses a risk to human health, particularly for children who may be exposed to contaminated soil through play or other activities. The 1000 ppm level serves as a guideline for assessing the safety of the environment and implementing necessary remediation measures.

Understanding the implications of this regulatory level helps in assessing potential health risks associated with lead exposure in various environments, especially in urban areas or places with a history of lead usage. This benchmark is essential for risk assessors to identify contaminated sites that may require further investigation or intervention to mitigate the risks associated with lead exposure.
