How is lead-contaminated soil typically abated?

Lead-contaminated soil is typically abated by removing and replacing it with clean soil because this method effectively eliminates the source of lead exposure. When soil is contaminated with lead, simply covering it or mixing it with clean soil does not eliminate the hazard. Lead particles can still be present, posing health risks, particularly to children who might come into contact with or ingest contaminated soil.

Replacing contaminated soil with clean soil ensures that the harmful lead is completely eradicated from the site, significantly reducing the potential for lead poisoning and other health issues associated with lead exposure. This practice aligns with best management and safety practices in lead abatement, emphasizing the necessity of thorough remediation to protect public health.
