Blackshare Environmental conducted an investigation of the subsurface beneath two concrete transformer pads where PCB laden dieletric fluid had leaked over a substantial period of time. Using direct push technology to delineate the PCB contamination, our team discovered elevated levels of PCBs at depths up to five feet. The concrete pads were removed and disposed of as PCB contaminated waste. An excavation plan was developed based on the subsurface investigation and a grid pattern was established for the initial excavation and removal of contaminated soil.
