Effect of humic acids on the bioremediation of polycyclic aromatic hydrocarbons from aquifers contaminated with petroleum

Suzanne Lesage, Wan-Chi Li, Kelly Millar, Susan Brown, Dickson Liu, National Water Research Institute Environment Canada

This web paper investigates the influence of humic acids on the microbial degradation of PAHs in fuel and oil products at a contaminated site. Solubility and mobility of PAHs in contaminated aquifers are discussed, evaluation of the potential use of humic acids as a remedial technology to enhance the solubility and biodegradation of residual PAHs.
