Description:
Information is presented for quantitative evaluation of treatment potential for creosote and pentachlorophenol (PCP) wood treating contaminants in soil systems. he study was conducted in three phases: 1) characterization, (2) treatability screening and (3) field evaluation. ata generated in phases 1 and 2 were discussed in a previous EPA Report (EPA/600/2-88/055). his report provides review of data generated during phases 1 and 2 plus discussion of data generated during the two-year field evaluation study. esults from this three-phase study indica ed that creosote contaminants, i.e., polycyclic aromatic hydrocarbon (PAH) compounds, and PCP are subject to degradation in soil systems; loading rates and previous exposure of site soil to particular contaminants were identified as important factors in determining rates of transformation for a particular site. lthough populations of PAH and PCP acclimated organisms increased markedly when these compounds were applied to test soils, no correlation was found between microbial population levels and transformation rates for specific compounds of concern. Migration of compounds of interest was negligible except in a highly sandy soil from one of the eight sites for which column leaching studies were conducted.
