Soil bioremediation using Petroleum Remediation Product
Carolina Resource Technologies, Inc. (CRT) has been providing bioremediation services to clients across the Southeast U.S. for more than 5 years. During that period of time we have used bioremediation to clean up 100,000 tons of petroleum contaminated soil for clients such as the U.S. Army and Navy, The Baptist Medical Association and numerous industrial and state regulatory clients.
Recently, CRT used two of our products in a site remediation project for a large waste hauling company in Columbia, SC. The project entailed the treatment of large areas of petroleum stained soil in an area where service vehicles had parked. The contamination was primarily confined from the surface to three feet so we simply used a backhoe to incorporate Oil Buster into the excavation and covered it with black poly and secured to protect the treated soil and to minimize moisture loss. Within two weeks, the soil had lightened considerably and the heavy fuel odor had disappeared. At four post treatment weeks, the heated soil was tested using hand held OVA and no petroleum concentrations in excess of 100 ppm were found.
The loose rock and stone that were treated with PRP were a surprise. The black oil that coated the rock and stone and been replaced by a white-ish residue at four weeks. Our past experience in bio-stimulation and bio-augmentation soil suggests that this residue is metabolized oil left behind by the elevated bacterial activity initiated by the PRP. OVA analysis of the heated residual material did not indicated the presence of petroleum hydrocarbon. In my view, these products have real potential in the clean up of petroleum spills on soil and in water.
You will also be interested to know that using PRP and Oil Buster allowed all of the clean up work to be accomplished at the client's site. As a result of this on-site treatment CRT was able to perform the entire site clean up for less than $20,000. The client had received competitive bids for more than $100,000.
As a firm specializing in the delivery of bioremediation services, CRT cannot afford to try many new products that come along, so I'm pleased that Oil Buster and PRP performed so well. I'm looking forward to using both products again.
