New Jersey is home to nearly 9% of the nation’s Superfund sites — more than any other state. They range from chemical plants with toxic byproducts leached into the soil, to oil-filled lagoons, open fields rife with septic waste and rivers polluted with toxic chemicals. Many have remained contaminated for decades.
In January, President Donald Trump signed a bill allocating $8.8 billion for the Environmental Protection Agency for the 2026 fiscal year. Within that budget, congressional appropriations specifically for the Superfund Program were set at $282.75 million—a 47% reduction from the previous year.
“It certainly warrants concern,” said Jim Woolford, former director for the EPA Superfund Remedial Cleanup Program. “This puts that program in competition with all the other parts of EPA. You’re dividing the pie, if you will, into smaller slices.”
In early April, Trump released his budget proposal for fiscal 2027, which begins Oct. 1. It cut EPA spending in half and slashed agency grants by $1 billion. Congress rejected similar spending cuts proposed by Trump last year.
An Inside Climate News analysis of federal workforce data released by the Office of Personnel Management shows that EPA lost more than 4,000 employees in 2025, the first year of Trump’s second term, reducing its staf to 12,849, its lowest level since the Reagan and Bush administrations in the 1980s. The 24% reduction was more than double the rate of losses across the entire federal government in 2025.
The Superfund program, which relies on many revenue streams, may be entering a new period of financial uncertainty just as cleanup momentum has begun to rebuild. Former agency officials and current lawmakers warn that staff and funding reductions are beginning to affect how the agency pursues polluters and moves contaminated sites toward cleanup. In New Jersey, the consequences could stretch cleanups even longer and keep communities at risk.
‘Polluter pays’
To see how those reductions ripple through the program, look at how Superfund is funded and how that structure has changed over time.
The Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA, is a federal law allowing the EPA to identify hazardous waste sites, compel responsible parties to pay for cleanups and draw from the Superfund Trust Fund when no viable polluter can pay. When the law was enacted, taxes on petroleum and chemicals fed that trust fund, employing the “polluter pays” principle.
Those taxes expired in 1995, and for decades the trust fund was largely supported by general Treasury funds and fines. Only in 2022 did Congress, under the Biden Administration, reinstate some of the “polluter pays” taxes, bringing chemical industry contributions back, and oil and petroleum in 2023 with the Inflation Reduction Act.
The oil and petroleum taxes do not expire, and the chemical taxes are set to run through 2031.
They haven’t yet lived up to expectations. The EPA’s budget documents show roughly $1.2 billion in total Superfund tax receipts in 2024 — less than half of the $2.5 billion estimated in the 2024 budget request. In 2025, tax receipts amounted to $1.6 billion — 26% below the administration’s original budget projections.
That revenue is now also being targeted. On Feb. 12, Republicans introduced a bill that aims to cut the “polluter pays” tax on petroleum and oil that Superfund relies on, even as the Trump administration sought in its 2026 budget proposal to transition fully from congressional appropriations to the polluter taxes only. Since the bill was introduced, there have been no hearings or votes scheduled. Prospects for passage are uncertain.
Separately, an infusion of critical funding is nearly exhausted. Under the Infrastructure Investment and Jobs Act, the Biden Administration also allocated $3.5 billion to the Superfund remedial program to work through and eliminate a backlog of 49 unfunded Superfund projects—at least seven of them located in New Jersey.
As of Oct. 16, 2024, the EPA has spent or allocated most of the money — $3.29 billion of the funds are spoken for.
Together, coinciding with the reductions the EPA is already facing, the program entered the 2026 fiscal year with few expendable dollars and tax revenue that hasn’t met projections — raising questions about how new cleanups can be started and how quickly older ones will be addressed. Even so, while tax revenues haven’t met expectations, revenue should still top $1 billion in 2026, enough to keep the Superfund Trust solvent for now.
“If you’re on a tight budget,” Woolford, the former Superfund director said, “what do you do? You don’t do all the things you’re planning on doing. You pinch pennies.”
‘Normal workforce dynamics’
The EPA is already buckling, holding fewer polluters accountable — likely due to staff cuts.
The EPA disputes claims that its Superfund work is slowing. In a statement, the agency said staffing levels fluctuate due to “normal workforce dynamics, including retirements, voluntary departures, internal mobility, and scheduled hiring,” and that it remains “fully capable of accomplishing our mission of cleaning up Superfund sites to protect human health and the environment.”
The agency said there have been no delays in cleanup progress thus far, and that it is working to accelerate Superfund projects.
New Jersey Rep. Frank Pallone Jr. (D-6th District), a longtime environmental policy leader, however, said the situation on the ground tells a different story.
“Trump’s EPA has already reduced the regional staff responsible for New Jersey by one third, making the progress we need nearly impossible,” Pallone said. “Delaying cleanups only makes them more expensive. We should be speeding up Superfund cleanups, not slowing them down.”
The Passaic River site in Newark — polluted by numerous companies, including a chemical company that made Agent Orange and other herbicides — for more than 40 years has been on the National Priorities List, a register of the country’s most contaminated sites, with no end in sight for remediation on the lower end of the river. Delays in testing sediment have taken so long that some site areas needed to be retested, according to Michele Langa, staff attorney at NJ/NY Baykeeper, a nonprofit advocacy group. The samples are good only for a limited time. She estimates five to eight years before results are expired and tests would need to be repeated for accuracy.
The Ringwood Mines in Passaic County, polluted by paint sludge and other waste from a Ford Motor Co. automobile plant that closed in 1980, became a Superfund site in 1983. It was deleted in 1994, and reopened in 2006 after more pollution was discovered. The EPA has only a blueprint for cleanup as of October 2025.
National Priorities List
The Superfund Program, Woolford said, hasn’t been totally financially stripped. One funding stream comes from the Superfund Special Accounts, which are funded entirely through settlements with responsible parties — not by annual Congressional appropriations or by the Superfund Trust Fund. Unspent settlement funds remain in site locations and can be used for future cleanup work at those locations.
However, any funding uncertainty—whether from expiring taxes or fluctuating appropriations—trickles down to staffing, slowing investigations or delaying enforcement against polluters and extending cleanup timelines. Over time, Woolford said, that erosion could become more visible.
One indicator, he suggested, would be changes to the National Priorities List itself. The list is designed to help the EPA determine which areas require further investigation and long-term cleanup plans. New Jersey has 115 active sites, and nationwide there are 1,343—an increase of three from 2024.
If any completed projects return to the list, Woolford said, that’s an indication of some internal funding or staffing challenges. At the same time, he warned that the agency may move to remove sites from the list prematurely.
“Expect a lot of EPA-sponsored press and focus on NPL site deletion or partial deletion,” he said.
According to the EPA, deleting a site from the National Priorities List is appropriate when the agency determines it is no longer a significant threat to human health or the environment. Woolford, though, said deletion does not necessarily mean contamination has been entirely removed. With Superfund sites stretching across New Jersey, and some projects left for decades, Woolford said the responsibility now falls on communities, tribes, states and local governments.
“This administration appears to be proposing and adding fewer releases or sites on the National Priority List,” Woolford said. “Communities are still being exposed to pollution, and fewer will see action from the federal government.”
He urged locals to ask more questions about optimal funding levels and expected project timelines, so they can independently assess benchmarks and ensure projects are moving forward as planned.
“New Jersey has the most Superfund sites in the country,” Pallone said, “so when Trump talks about cutting funding for this program, our communities hear one thing: more years living next to toxic contamination that should have been cleaned up already.”
