Controversy Surrounds Chester County Data Center Construction on Superfund Site

Construction of a large data center in East Whiteland Township, Chester County, has come to an unexpected halt. The project, planned to cover 1.5 million square feet and developed by Green Fig LLC and Sentinel Data Centers, sits atop the former Cyprus Foote Mineral Company site. This location is a federal Superfund site, contaminated with hazardous substances such as lithium, arsenic, and hexavalent chromium since the 1940s. The stop-work order issued by township officials follows growing concerns from residents about environmental safety and the potential health risks posed by the construction.

Background of the Superfund Site and Contamination

The former Cyprus Foote Mineral Company site has a long history of industrial contamination. Since the mid-20th century, the area has been polluted with toxic chemicals including lithium, arsenic, and hexavalent chromium. These substances are known for their persistence in the environment and potential to cause serious health problems. The Environmental Protection Agency (EPA) placed the site on its National Priorities List, designating it as a Superfund site requiring long-term cleanup efforts.

Groundwater contamination remains a significant issue, with an ongoing plume of pollutants spreading beneath the surface. Elevated levels of volatile organic compounds (VOCs) have also been detected. Despite these challenges, the EPA has stated that the current cleanup remedy should not be disrupted by the data center construction project.

Residents’ Environmental Concerns and Safety Fears

Local residents have voiced strong opposition to the construction, citing several environmental concerns. Dust generated by construction activities could spread contaminants into the air, posing risks to nearby homes and a daycare facility located close to the site. Parents worry about the health of their children, especially given the toxic history of the land.

Residents also question the soil-testing protocols used by the developers. They argue that the testing lacks transparency and may not fully capture the extent of contamination. These concerns have created tension between the community, developers, and township officials, who maintain that the site is safe for construction.

Chester County Construction and Project Delays

The data center project has faced multiple delays and revisions since its inception. Initially, developers sought to expand the building footprint but later proposed shrinking it. Most recently, they requested a "field change" to replace water-cooling systems with air-chilled units. This change sparked accusations from residents that the developers were pushing through a substantial redesign without proper review by the township board.

In early July, the township supervisors decided to table a decision on the amended plans until more information could be gathered. This pause leaves the future of the project uncertain and prolongs the debate over environmental safety.

Balancing Development and Environmental Responsibility

The situation in East Whiteland Township highlights the challenges of balancing economic development with environmental responsibility. Data centers are critical infrastructure in today’s digital economy, requiring large spaces and significant cooling systems. However, building on a contaminated site raises complex questions about risk management and community trust.

Developers argue that modern construction techniques and remediation efforts can safely contain contaminants. They emphasize the importance of following EPA guidelines and township regulations. Meanwhile, residents demand more rigorous oversight and assurances that their health and safety come first.

What This Means for Chester County Residents

For homeowners and parents in Chester County, the halted construction serves as a reminder to stay informed and engaged with local development projects. Environmental concerns around the data center reflect broader issues about land use, pollution, and public health.

Residents can take several steps to protect their interests:

• Attend township meetings to voice concerns and ask questions

• Request detailed reports on soil and groundwater testing

• Advocate for independent environmental assessments

• Monitor updates from the EPA and local officials

  
  

By staying involved, the community can help ensure that any future construction prioritizes safety and transparency.

Moving Forward with Caution and Care

The Chester County construction project on a Superfund site remains at a crossroads. The stop-work order reflects the seriousness of environmental concerns and the need for careful evaluation. Developers, township officials, and residents must work together to find a path forward that respects both economic goals and community health.

This case underscores the importance of clear communication, thorough environmental testing, and responsive local governance. Chester County residents should continue to follow developments closely and advocate for solutions that protect their environment and well-being.

The future of the data center project depends on balancing progress with precaution. The community’s voice will play a crucial role in shaping what happens next.
