At a meeting Wednesday night, Sunoco LP and parent company Energy Transfer presented its cleanup plan for the estimated 6,500 gallons of jet fuel leak from its pipeline that contaminated well water in Bucks County’s Upper Makefield Township.
The company submitted its Remedial Action Plan to the Pennsylvania Department of Environmental Protection in June. The document, prepared by Verdantas LLC, outlines how Sunoco LP will meet the agency’s Act II remediation cleanup standard.
Sunoco LP is proposing a pilot test of a process called multiphase extraction, abbreviated as MPE, to clean up the leaked jet fuel that seeped through fractured bedrock and remains in the groundwater.
The estimated month-long pilot test will most likely take place before the end of this year, company representatives said. If proven effective, a full-scale system will be installed.

Eyre neighborhood would expedite the cleanup process of a Sunoco pipeline leak at a meeting in Washington Crossing, Pa., on Wednesday, July 8, 2026. (Emily Neil/WHYY)
Pipeline leak cleanup disrupts a once ‘bucolic, beautiful neighborhood’
Residents and elected officials packed The Crossing Church gymnasium in Washington Crossing on Wednesday. They expressed concerns about noise and safety, and impacts on the water supply.
Ben Weldon, chair of the Upper Makefield Township Board of Supervisors, said the cleanup is “moving too slowly,” and that identifying a long-term clean water source in the affected Mt. Eyre neighborhood would expedite the process.
“Presumably one of the reasons this is moving slowly is because we are trying to clean an aquifer that you all are accessing for your drinking water,” Weldon told the crowd. “They have to consider, they have to plan … and mitigate what happens when what they do in this aquifer impacts all of your homes. If you had a separate, a different water source, presumably this cleanup could happen much quicker.”
Other residents cited concerns about safety and noise levels from the equipment, which company representatives said would run around the clock during the pilot and eventually during the full-scale cleanup.
“This is a major interruption into what was a bucolic, beautiful neighborhood,” said Terry Dearden, a Mt. Eyre resident. “So, regardless of the fact that we all are ticked off about the fuel, we now do not live in the neighborhood that we paid a whole lot of money for.”
As of June 16, the company said it has recovered approximately 518 gallons of jet fuel. Sunoco has recovered an additional 644 gallons through soil excavation beneath the pipeline.
The company also said it collected more than 1,800 water samples from 365 private drinking water wells in the neighborhood. Since the leak was discovered in January 2025, the company has provided bottled water and installed more than 200 Point-of-Entry Treatment, or POET, water filtration systems to prevent exposure to the leaked chemicals and impacted groundwater.

Kim Brunnquell, a resident, expressed concerns Wednesday about the continued maintenance of the water filtration systems. She showed a sediment filter removed in June that had turned black with debris in three months.
“The POET filter systems are a treatment, not a solution,” she said.
Several residents also raised concerns about dozens of redacted pages in the public version of the plan, which company representatives at Wednesday’s meeting attributed to privacy concerns about addresses.
