EPA Reassures Residents on Lead Levels in Fire-Affected Properties
The U.S. Environmental Protection Agency (EPA) has assured residents that most properties cleared by the U.S. Army Corps of Engineers do not exhibit dangerous lead levels, following soil tests conducted at a fraction of the homes impacted by the Eaton Fire. However, one outside expert remains skeptical regarding the findings.
Impact of the Eaton Fire
In January 2025, the Eaton Fire ravaged 9,400 homes and structures in the Altadena area, dispersing smoke laden with lead, arsenic, and asbestos into the atmosphere, which subsequently settled nearby. Lead is known to be a potent neurotoxin associated with severe developmental issues in children.
Testing Results and Compliance
The EPA randomly inspected 100 homes within the debris removal zone, discovering that only five units surpassed the agency’s lead testing benchmarks, as detailed in a report shared with NBC News. Meanwhile, seventeen parcels exceeded California’s more stringent standards. Overall, the median lead concentrations across all properties remained significantly below levels of concern set by both state and federal authorities, according to an EPA news release.
Confidence in Cleanup Measures
“This should instill confidence among residents that the Corps effectively addressed contaminants related to the fire, especially lead,” stated Michael Montgomery, director of EPA’s Region 9 Superfund and Emergency Management Division. He emphasized that the Corps adequately removed ash, debris, and the underlying contaminated soil.
Concerns Over Comprehensive Testing
Despite the positive findings, skepticism lingers. Andrew Welton, a professor of civil, environmental, and geological engineering at Purdue University, criticized the EPA’s methodology, claiming it does not adequately identify areas with heightened risk. He argued that the data gathered may not reflect the true risk levels faced by the community following the fire.
Scrutiny Over Cleanup Procedures
The debris removal process, managed by the Army Corps, has faced criticism from whistleblowers who assert that the operation was inconsistency and rushed. Some reported that more debris was left behind than in previous wildfire cleanup efforts, raising concerns about ongoing contamination for residents.
Implications of Soil Testing Findings
Soil testing was not mandatory during the cleanup, prompting local scientists and health department consultants to conduct independent testing. The results have been varied and raised numerous concerns. The pooling of samples from different locations, according to Welton, might mask contamination hotspots, suggesting that certain properties may still have hazardous lead levels despite passing EPA benchmarks.
The EPA’s test results indicate that five surface samples exceeded federal standards, with one particularly concerning sample testing at 705 mg/kg of lead. Welton cautioned that properties with contamination levels averaging above this figure warrant particular scrutiny, as those exceeding 1,000 mg/kg are classified as hazardous waste.
