Oil Spill Stain Cleanup

Oil Spill Stain Cleanup

CommTank was called by an oil company who was repairing an oil-fired hot water tank and caused a spill of a few gallons of heating oil. Despite their best efforts to remove the oil,replace the kickboards, and steam clean the floor, the fuel odor still permeated the cellar in this Stoughton, Massachusetts home. The stain covered an area about 4' x 4' on the concrete floor. The oil company’s insurance provider approved a claim for the oil spill stain cleanup and CommTank sent a plan to them for removing the stain and odor. The following is an outline of that plan.

Upon completion of the excavation, restoration of the floor and reinstallation of the oil tank and water heater, CommTank technicians took air quality readings and found that they were below Massachusetts acceptable limits for volatile organic vapors (readings of 4.5 PPB with the highest being 5.6 PPB). The insurance company reviewed the results and confirmed these readings were very low. The owner and his wife were satisfied with the floor restoration and odor level compared to when work first began. The owners were provided with a report explaining the work performed and the results of the air quality testing.
