Sentinel / Green Fig data center at Foote Mineral Superfund site (East Whiteland)
Also called: Project Forge, 1547 Chester County site
Developers are building a 1.5-million-square-foot data center on a former Superfund site in East Whiteland Township. The township stopped work twice in 2026, most recently because there is no proof of enough water. Developers offered to shrink it to 536,000 square feet.
Where things stand: Early construction started, but the township issued a second stop-work order Aug. 26, 2026 over water supply.
π Latest update (Aug 26, 2026): Second stop-work order until Aqua confirms enough water.

β Still unanswered
Nobody has answered these in public yet. Can you help find out?
- Will Aqua commit enough water? π I'll find out
- Is the Superfund site safely cleaned up? π I'll find out
- Who is the end user? π I'll find out
- Will the plan be downsized? π I'll find out
π What we checked
- Oct 6, 2026: We checked the Delaware River Basin Commission's (DRBC) list of pending applications (August 2026): there is no application for this data center. DRBC said in November 2025 it had not received any data center applications. A data center needs its own DRBC approval only if it takes more than 100,000 gallons a day from its own wells or streams, or discharges more than 50,000 gallons a day (lower limits in some protected areas). Buying water from a water company does not need a separate DRBC approval.
What happened so far
- 2024Township approved the final design (two buildings of about 772,000 sq ft each).
- July 2026First stop-work order over soil and safety plans at the Superfund site.
- Aug 19, 2026Residents showed supervisors a 2024 letter from Aqua, found through a public records (Right-to-Know) request, that said: 'Aqua does not have the capacity to meet the peak demand ... as requested.' Aqua suggested a water storage tank on the site.
- Aug 26, 2026Second stop-work order until Aqua confirms enough water.
Local votes and rules
π³οΈ Public vote
Voters will decide on Nov. 3, 2026 whether to grow the township board from 3 supervisors to 5. Residents gathered at least 500 signatures to put the question on the ballot. They acted after anger over how the township handled a 1.5 million square foot data center plan on a former 79-acre Superfund site.
π Data center rules
East Whiteland supervisors voted unanimously for a 32-page data center ordinance. It sets distances data centers must keep from homes, schools, daycares, parks and churches, and limits noise, water use, cooling systems and power supplies. It does not apply to the data center already being built.
π Other
East Whiteland ordered the developers to stop work on the data center at the former Foote Mineral Superfund site. The township said work cannot restart until the water company confirms enough water is available. It was the second stop-work order that summer.
βοΈ Court case
A county judge threw out two appeals by residents who challenged the township's approvals for a 1.5 million-square-foot data center on Bacton Hill Road. The judge called the appeals frivolous, noting one came eight years after the 2018 zoning decision.
π Other
With hundreds of residents present, the East Whiteland Planning Commission voted unanimously to urge supervisors to look hard at Green Fig's plan to grow its approved data center from 1 million to 1.7 million square feet.
βΈοΈ Pause on new data centers
East Whiteland supervisors started a 180-day pause on new data center proposals so the township could write data center zoning rules. The pause did not stop the data center already approved at the old Foote Mineral site.
β Approved
East Whiteland supervisors granted development plan approval for a data center at 13 S. Bacton Hill Road, on the former Foote Mineral Superfund site. The project builds on a zoning permit from 2018 and is now under construction.
