Bench-scale biotreatability studies were performed to evaluate the potential for using a solid-phase bioremediation process to ameliorate pentachlorophenol-(PCP-) and creosote-contaminated sediment and surface soil present at the American Creosote Works Superfund site, Pensacola, FL. The effects of tilling and fertilization on the rate and extent of biodegradation of PCP and 42 targeted creosote constituents by indigenous microflora were monitored by gas chromatographic analysis of organic extracts of soil and sediment; changes in microbial populations were also recorded. Specially designed landfarming chambers allowed for the quantitative analysis of targeted pollutants lost through abiotic processes. In general, solid-phase bioremediation resulted in slow and predictable losses of targeted pollutants (i.e., low molecular weight creosote constituents were more readily biodegraded than higher molecular weight contaminants), and the more recalcitrant pollutants (e.g., PCP) tended to persist. Performance data from these studies suggest that full-scale site remediation employing solid-phase bioremediation strategies in the time defining these studies. (90 days).
