Determination of bioremediation effectiveness requires a methodology to quantify in situ biodegradation. Biodegradation of a target compound can be quantified by following the time dependence of the concentration ratio of the target compound to a conservative, natural internal standard. The molecular marker, 17{alpha}(H), 21{beta}(H)-hopane, a multi-ringed saturated hydrocarbon, has been used as an internal standard to quantify in situ biodegradation of petroleum-contaminated sites. This study critiques the use of hopane for the quantification of PAH biodegradation in soil contaminated with highly weathered petroleum. This work shows that the use a combination of several molecular markers as conservative internal standards is a more effective quantification technique for sites contaminated with crude oil from a number of sources.
