Communities across the country may still be exposed to dangerous pollution from millions of long-abandoned oil and gas wells.
Here's what to know
In a YouTube short for EcoBits (@EcoBitsOfficial), host Justin Pack highlighted how many abandoned oil and gas wells in the United States may still lack caps. Citing EPA estimates, he said there were 3.7 million of these "zombie wells" in 2023, and roughly 58% may be uncapped. Methane, oil, hydrogen sulfide, and sometimes toxic wastewater can continue leaking from those unused sites.
They were left behind after drilling companies stopped using them, leaving long-term hazards at former industrial locations.
"So, even though the well is dead, the pollution isn't," Pack said.
When the companies responsible for cleanup have gone bankrupt or otherwise cannot pay, taxpayers can end up covering the cost of plugging and maintaining old wells.
Because so many may be uncapped, the problem is not just aging infrastructure or incomplete records; it can also bring ongoing leaks and explosion hazards to nearby communities.

What can be done?
The video pointed to policy approaches intended to keep abandoned wells from becoming a public expense. Pack said efforts have tried to require drillers to put money up front so they can later cover and plug the wells they create.
He also said there had been efforts to fine companies for methane waste, giving them a financial reason to prevent leaks instead of overlooking them.
Both measures target companies profiting from drilling while leaving pollution and cleanup behind. Pack said Congress repealed those efforts this year, leaving communities near old wells to deal with the consequences.
Even if an operator can no longer pay, the work still has to be done — plugging wells and addressing leaks at the millions of abandoned sites the EPA estimated were spread across the country in 2023.
Pack said, "So, we're not only dealing with the pollution from oil and gas we use today, but we're paying for wells drilled decades ago."
Where can I learn more?
Abandoned wells are causing problems for multiple communities across the United States.
• In Texas, regulators confronted zombie wells threatening communities as poorly plugged sites evaded detection.
• In Arizona, federal funds helped plug orphaned wells poisoning land after generations of neglect.
• On the Louisiana border, officials raced to contain a decades-old well leak spreading oil.
• Researchers have said abandoned wells could become next-gen energy storage instead of remaining hazardous holes.
