Understanding the New EPA Lead Clearance Levels
As of Friday, January 17, 2025, significant updates to the EPA’s lead clearance levels will take effect, impacting how environmental firms like ours approach sampling and reporting. These changes are pivotal for teams working in Indoor Air Quality (IAQ) and Environmental Assessment (EA). Let’s break down what this means for us and the communities we serve.
What’s Changing?
In October 2024, the EPA finalized stricter rules for identifying and cleaning up lead-based paint hazards in pre-1978 homes and childcare facilities. These updates recognize a critical fact: there is no safe level of lead in a child’s blood. The new standards aim to further protect vulnerable populations by reducing allowable lead levels to the lowest measurable amounts.
Updated Lead Clearance Levels
- Floors: Reduced from 10 µg/ft² to 5 µg/ft².
- Windowsills: Reduced from 100 µg/ft² to 40 µg/ft².
- Window Troughs: Reduced from 400 µg/ft² to 100 µg/ft².
Additionally, the EPA has lowered lead screening levels for residential soil:
- From 400 ppm to 200 ppm.
- In properties with multiple sources of lead exposure, the level is further reduced to 100 ppm.
Why These Changes Matter
The goal is clear: reduce the risks of lead exposure, especially for children and other vulnerable populations. Lead contamination, whether from paint, dust, or soil, poses severe health risks, including developmental delays and neurological damage. By tightening these standards, the EPA aims to close gaps in public health protection.
Impact on Environmental Work
The updated regulations will influence:
- Sampling Procedures: Teams will need to ensure lead levels in dust, soil, and abatement sites meet the stricter thresholds.
- Reporting Standards: All laboratory analyses must align with the updated clearance levels, as per EPA’s National Lead Laboratory Accreditation Program.
- Brownfield Assessments: For properties intended for residential reuse, EPA’s Brownfields Program will adopt the new screening levels, ensuring these sites are safe for future occupants.
What Are Screening Levels?
Screening levels help identify areas that may require further investigation. However, they are not cleanup levels. For example:
- Screening Levels: Used early in site assessments to identify potential risks.
- Cleanup Levels: Define the concentration of lead that must be achieved to ensure safety for the site’s intended use.
For residential properties, cleanup levels will account for various factors, including:
- Type and extent of contamination.
- Future site use (e.g., residential or industrial).
- Vulnerable populations present (e.g., children or women of childbearing age).
Staying Informed
These changes mean a shift in how we approach both site evaluations and community engagement. For example, EPA contractors conducting Brownfields assessments will incorporate the updated screening levels into reports and provide site-specific recommendations.

- The EPA’s updated guidelines on lead hazards.
What’s Next?
As we implement these changes, clear communication will be vital. We’ll keep our partners, clients, and community members informed of what these updates mean for their projects and health. If you’re involved in TBA (Targeted Brownfields Assessments) or other lead-related projects, now is the time to review the updated protocols and consult with your points of contact for guidance.
This is a pivotal moment for environmental health, and we’re proud to adapt and lead the charge in safeguarding our communities. By adhering to these stricter standards, we are not just complying with regulations—we’re championing safer, healthier environments for everyone.
