Field Implementation Of Bioremediation At Indot Facilities-Phase I, Loring F. Nies, Brett Robert Baldwin, Matthew B. Mesarch

JTRP Technical Reports

Bioremediation is often the most cost-effective and successful technique available for the remediation of soils and groundwater contaminated with organic pollutants (e.g. petroleum). The goal of bioremediation is to stimulate naturally occurring microorganisms to biodegrade the contaminants to harmless products. To be in compliance with EPA regulations all underground fuel storage tanks must have spill, leak and corrosion protection. Many older obsolete tanks had deteriorated to the extent that petroleum products had leaked into the environment. In the past, petroleum contaminated soils were typically excavated, followed by landfilling of the contaminated material. The continued use of landfills for disposal of …
