摘要

The intrinsic biodegradation of petroleum hydrocarbons in a contaminated aquifer wouldchange the chemical constitution, which can be indicated by various geochemical footprints. The variations of TPH, generation of acceptor reduction and significant geochemical parameters have been analyzed on the ground of geological and hydrogeological conditions of a petroleum hydrocarbon-contaminated site. The results showed that biological degradation existed in contaminated site, such as oxygen reduction, nitrate reduction, sulfate reduction. Meanwhile, sulfate reduction took dominant position in all degradation due to its high concentration at site.
