Nitrate and perchlorate were biodegraded most rapidly, followed by RDX and then HMX, although the rates of biological reduction for the nitramine explosives were appreciably slower than observed for mZVI or nickel.

Chloride and bicarbonate (aerobic biodegradation by-products) concentration increases were used to estimate that 300 1000 kg of chlorinated hydrocarbons were biodegraded, although the ratio of 1,2 DCA to VC that was biodegraded remained uncertain.

Through comprehensive geological and geochemical analysis of the oils and gases, it is recognized that the oils were generated from Mid-Upper Ordovician source rocks, migrated from paleo-oil-accumulations in Ordovician, and were biodegraded to produce different heavy oils before the late Hercynian orogeny (about 250 Ma), so that the oils in the Carboniferous are secondary oil accumulations.
