The Institute of Gas Technology (IGT) has been developing several techniques to improve biodegradation rates over and above what can be achieved by simply adding nutrients and water and adjusting soil pH: chemical and biological treatments to increase the bioavailability of PAH's to microorganisms for catabolism; the addition of growth substrates to promote cometabolism of multi-ring PAH's that cannot be degraded otherwise; and the addition of a specially developed, mixed bacterial culture to ensure the presence of required types and quantities of PAH-degrading microorganisms. Further work is needed, however, to optimize the soil treatment protocols and to determine the effects of other organic components and heavy metals present in the soil and environmental factors on the overall treatability of the contaminated soil. 6 refs., 12 figs., 5 tabs.
