The legal action, filed in the Philadelphia Court of Common Pleas, centers on Tank 708, a storage vessel installed in 1951. According to the complaint, a quarter-inch hole in the tank floor allowed gasoline to bleed into the surrounding bedrock and groundwater from March to December 2025. While the operators reportedly spotted fuel on the facility grounds in August, they allegedly labeled the situation as routine maintenance rather than an environmental emergency.

Testing has since confirmed the presence of benzene, naphthalene, and other hazardous chemicals in nearby wells and indoor air. The Pennsylvania Department of Environmental Protection and the federal Pipeline and Hazardous Materials Safety Administration have both issued orders against the companies, citing unlawful discharges and a failure to report the incident. Residents within one mile of the site are now seeking compensation for property damage, diminished home values, and long-term medical monitoring to address potential health risks from the exposure.
