The Flatwater Free Press and ProPublica conducted independent soil testing of over 600 properties in east Omaha, Nebraska, and found that despite the EPA spending $273 million on remediation since 1999, toxic lead levels persist in yards marked as cleaned up decades ago. The investigation, spanning more than two years, revealed that 1 in 10 remediated yards still exceed EPA cleanup standards, and nearly a quarter of tested properties could qualify for further study under new Trump administration guidance—raising questions about the effectiveness of what the EPA has called the nation's largest residential lead cleanup effort.
- 1 in 10 EPA-remediated yards in Omaha still exceed lead safety thresholds; nearly a quarter could qualify for additional cleanup under new federal guidance.
- Mary Royers' property, marked remediated in 2012, now tests at 1.5 times the EPA cleanup standard, illustrating the scope of incomplete remediation.
- Journalists tested 600+ properties over two years using independent methodology (single yard samples) versus EPA's multi-section approach, reaching far more residents.
- Lead contamination clusters geographically; many high-testing remediated yards have unremediated neighbors with equally high contamination, suggesting EPA cleanup strategy gaps.

Analysis Case study of Mary Royers
Article highlights a homeowner whose yard was marked remediated in 2012 but testing finds lead levels 1.5 times higher than the EPA's cleanup standard, connecting soil contamination to concerns about her daughter's blood lead levels.
“You have the green light from the city. That means everything's safe. I remember thinking, 'Thank God I don't have to worry about that.'”

Analysis Expert commentary on findings
Howard Mielke, lead-contamination expert at Tulane University, states the EPA should not only clean up high-contamination areas but also test other homes, noting that high results cluster geographically.
“If you find a couple of high results, chances are many high results will be nearby.”

“One in 10 Omaha yards we tested that the EPA cleaned up still has enough lead in the dirt to be over the agency's threshold.”

One Omaha mother believes lead in her yard is partially responsible for the lead in her daughter’s blood. The EPA remediated her property in 2012, but we found that contamination levels are even higher now than they were before. with @flatwaterfreep.bsky.social

The EPA and the city of Omaha have spent decades cleaning up residential properties in the city’s Superfund site after a century of pollution. But they don’t always retest yards — even when kids who live there test high for lead. with @flatwaterfreep.bsky.social

NEW: The EPA hasn’t reevaluated its cleanup guidelines for homes in a residential Superfund site in Omaha, Nebraska, in 17 years, despite research showing that even small amounts of lead can cause IQ loss in children and heart attacks in adults.

@flatwaterfreep.bsky.social and @propublica.org independently tested hundreds of homes in eastern Omaha, Nebraska, and found toxic levels of lead in soil throughout — including in yards that the EPA remediated years ago. Here’s how we did it.

The EPA spent hundreds of millions on lead remediation in Omaha, Nebraska, home of the nation’s largest residential Superfund site. New soil tests by the @flatwaterfreep.bsky.social and @propublica.org show that many yards still have harmful levels of lead.
