January 17, 2024. Press Release. Biden-Harris Administration Strengthens Safeguards to Protect Families and Children from Lead in Contaminated Soil at Residential Sites "Utilizing updated, best available science, EPA lowers screening levels for the first time in 30 years. [   ] EPA is lowering the screening level for lead in soil at residential properties from 400 parts per million (ppm) to 200 ppm. At residential properties with multiple sources of lead exposure, EPA will generally use 100 ppm as the screening level. Screening levels are not cleanup standards. While this update will help EPA site teams make site-specific cleanup decisions to protect nearby communities, EPA makes cleanup decisions specific to each site, using site-specific factors, including risk factors and community input that can vary from site to site. [   ]  While the guidance goes into effect immediately, EPA welcomes feedback from the public that may be considered in any future updates to the guidance. Please submit written feedback on the guidance in the public docket (Docket ID: EPA-HQ-OLEM-2023-0664) for 60 days from January 17, 2024, to March 17, 2024.

What can property owners do to address high lead levels in soil?

There's no simple answer to remediating lead in soil. 

Anything that is a barrier between the contaminated soil and the children should work. The fact that your grandchildren have not picked up lead from the grassy area suggests that you have that space under control.
