The Bottom Line and Conclusion <br /> f5 3CS believes that bioremediation offers a cost effective technology for treating diesel- <br /> contamii ated sail This bioremediation protect included the determination of the extent <br /> of contamination, required sampling and analysts to characterize the contaminant, acute <br /> bioassay to determine the toxicity of the diesel-saturated soil, excavation of the sot], and <br /> the bioremediation Treatment and sampling The entire project, including constructions <br /> of bids and report preparation, cost approximately $30,000. - 3 <br /> The ultimate destruction of the contaminant in diesel-laden soil utilizing bioremediation <br /> by indigenous microorganisms, when carried to completion, converts the aies.l- <br /> contaminated or hazardous organic compounds into the innocuous substances, carbon <br /> dioxide and water. In our opunon, bioremediation is a proven technique ,-,tth enormous <br /> potential for the effective decontamination of sites with soil containing heavy hydrocarbon <br /> fuel, such as diesel. Bioremediation can result in a task done efficiently, safely, <br /> permanently, and done at extremely low costs. If, in fact, a larger lens had been <br /> discovered in the above case, the cost per cubic yard of the remediation would have <br /> decreased precipitously. <br /> The technique of bioremediation has a great deal of potential. In the future, the <br /> application of bioremediation, using the many types of microorganisms which are being <br /> developed, may be utilized for materials other than hydrocarbon-laden soils Although <br /> there are possibly certain types of hydrocarbon-contaminated materials that may not be <br /> as easily bioremediated, this process has proven to be an easy, efficient method for <br /> treating contaminated soils that contain low volatile, easily degradable diesel and waste <br /> oils. <br />
