RALEIGH, NC, Feb. 26, 2010 -- Piedmont Geologic, an environmental consulting firm, announced today the startup of a new groundwater remediation project at a major gasoline pipeline release site in the Ohio River valley. This represents the culmination of the site assessment and remediation planning/implementation phase of the organization's work. Site cleanup is projected to be completed in three to five years.

The site is the location of an underground fuel pipeline leak which resulted in the accumulation of gasoline in the area water table. Approximately 70,000 gallons of gasoline have been recovered through the initial twelve months of interim site remediation efforts, which were focused mainly on preventing seepage of gasoline into the Ohio River. Both state and federal agencies have been pleased with the results achieved to date.

The final phase of work is the installation, startup, and operation of a groundwater remediation system. Using a total of 60 remediation wells, the system will involve a combination of fluid extraction to remove gasoline and contaminated groundwater from the water table and vapor extraction to remove gasoline from soil and the water table. Recovered gasoline will be recycled and recovered vapors will be destroyed using thermal oxidation technology.

"It was crucial to the site owners and their insurer that we were able to respond very quickly to both assess the scope of the release and design and implement a full-scale groundwater remediation system," said Piedmont Geologic President and Principal Geologist, Pete Dressel. "Additionally, they were looking for a system designed and installed in a manner that would minimize impact on normal retail operations by property owners and we were happy to provide a solution to meet their needs."

"Piedmont's capability to rapidly respond to this loss and install efficient recovery equipment significantly reduced the potential for third party claims. These response efforts focused on immediate recovery rather than investigation which will reduce long term remediation expenses," said Chris Fisher, Environmental Consultant with XL Specialty Insurance Company. "Following the response, Piedmont's delineation of the impacts, remedial design and installation have produced excellent results. I look forward to working with Piedmont on future projects."
