Lawrence Memorial Hospital UST Removal & Installation
CommTank was a subcontractor of Delphi Construction during the removal and installation of a 20,000 gallon underground storage tank at the Lawrence Memorial Hospital. The project was comprised of a temporary tank installation, piping of the temporary tank to the boiler, transferring fuel, entering and cleaning the underground storage tank (UST), removing the UST, excavating additional soil to accommodate the new tank, and installation of the new UST. One unexpected change of scope was the contamination found around the original tank. It was unlikely that the source of the fuel release was from the recently removed UST. The UST removed didn’t have any pin holes, didn’t show excessive amounts of corrosion and it was of double wall construction.

After a site assessment, it was determined that readings found during the soil testing were the residual concentrations from the leaking UST, closed approximately 20 years ago. Because the contamination was limited in extent, CommTank was able to remove 100 tons of Petroleum Contaminated Soil and 10,000-gallons of petroleum contaminated groundwater, with a minimal amount of delay to the project schedule.
