While lead exposure has decreased significantly over the past few decades, lead pollution lingering in soil still poses health risks for many urban communities. Lead exposure is particularly dangerous to children, leading to severe intellectual disabilities along with other lifetime health impacts. EPA researchers are working to reduce childhood lead exposure by exploring new ways to clean up lead in contaminated sites.
EPA researchers and partners are working on methods to turn toxic lead into less harmful forms through soil additives. Successful soil additives, or amendments, would interact with lead contamination and make it insoluble if ingested. Not all soil additives work for every type of soil or site, so researchers and contaminated site managers are exploring new options for reducing health risks.
