GPR Data Inc. was called in to investigate this sinkhole in December 2007, but what we discovered was not what anyone expected. The sinkhole had been completely attributed to raw volume of water traveling through a drainage pipe. However, upon investigation with ground penetrating radar, we determined that three underground storage tanks had been buried and forgotten, in close poximity to the sinkhole. At least one of the tank walls had been destroyed by electrolysis, creating an open void which allowed sub-surface evacuation of the subgrade structure.
