Biodegradation of Coal Tar Constituents in Aquifer Sediments
In situ bioremediation is an important technology for the cost-effective treatment of contaminated soils and groundwater (NRC 1993). Trial-and-error methods of implementing this complex process at a field scale are inefficient and costly. Therefore, it is important to conduct laboratory studies to establish feasible microbial reactions and to develop reliable engineering models that can analyze in situ options prior to field testing. Specifically, it is important to establish the appropriate chemical conditions required for biodegradation of the contaminants and to assess the relative importance of mass transfer (bioavailability) versus kinetic (biodegradation control) effects.
