  • 50 properties prepared for beneficial reuse and future economic development
  • Cleaner groundwater and soil for improved human health and safety
  • Environmental threats mitigated.

From the 1950s through the early 1990s, toxins poured into Florida’s soil as the result of petroleum contamination incidents. During this time, thousands of old gas stations, bulk storage facilities, underground storage tanks, and surficial spills released fuel into the earth. The petroleum made its way into the groundwater, which provides 98 percent of the state’s potable water. Absent a full understanding of the environmental impacts and implications, scores of these spills went undetected and unreported.

Taking aim at this widespread contamination, the Florida Department of Environmental Protection (FDEP) adopted the Florida Petroleum Restoration Program. Under the program, the FDEP is helping to fund the remediation of sites across the state, stretching all the way from Miami, north to Jacksonville, and west to Pensacola. The remediation program is designed to provide large-scale benefits to Florida, with positive impacts on human health, the environment, and the economy.  

What We Did

During a period of five years, Gannett Fleming is responsible for the comprehensive assessment and remediation of more than 50 sites. Groundwater, soil, and surface water sampling is completed to delineate the extent of the contamination, while receptor surveys are conducted to determine the potential impact to potable wells, wetlands, streams, and other environmentally sensitive areas. The firm then develops the most appropriate remediation plan for the site conditions, taking into account the prescribed schedule, contamination levels,  accessibility to the contamination, and the site’s intended future use. Gannett Fleming also oversees all remedial activity, including drilling, excavation, soil disposal, in-situ treatment, and the installation of groundwater treatment systems, as appropriate. Upon completion, the FDEP issues a site rehabilitation completion order, which indicates that remediation has been finalized, no further action is required, and the site is ready for beneficial reuse.

Key Features

  • Multiyear environmental assessment and remediation initiative
  • More than 5,000 soil and groundwater samples collected from 50 sites across the state
  • Sonic drilling for the efficient and environmentally sensitive penetration of a range of geologic conditions.

Sustainability Features & Outcomes

  • Sonic drilling dramatically reduces investigative-derived waste by 90 percent—eliminating tons of contaminated soil and groundwater that would otherwise go to landfills.
