EPA lowered its recommended screening levels and strengthened guidance for investigating and abating lead in contaminated soil, a move that is expected to expand the number of homes investigated for possible cleanup. EPA lowered the screening level for lead in soil at residential properties from 400 ppm to 200 ppm (100 ppm for residential properties with multiple sources of exposure). The updated standards will help better protect communities from lead poisoning, particularly those disadvantaged and overburdened communities experiencing lead poisoning from a range of sources.

While the guidance goes into effect as of Jan. 17, 2024, EPA is welcoming public comment for future updates to the guidance. Read comments on the lead exposure guidance.
