The Minnesota Department of Transportation (Mn/DOT) excavates thousands of cubic meters of petroleum-contaminated soil annually. The Minnesota Pollution Control Agency requires that this contaminated soil be treated. Faced with the prospect of an increasing quantity of contaminated soil and few feasible treatment options, Mn/DOT investigated the use of bioremediation. The bioremediation treatment process is similar to composting. Naturally occurring microorganisms found in organic matter consume petroleum hydrocarbons as a food source. Mn/DOT's bioremediation technique is low cost, low technology, low maintenance, and totally contained. The process does not adversely affect the environment. Further details of the process are provided in this article.
