Comparison of Eh and H2 measurements for delineating redox processes in a contaminated aquifer

Quantitative analysis of oxidation-reduction potentials (Eh) and levels of dissolved H2 was conducted in jet fuel-contaminated aquifers of Wurtsmith Air Force Base, MI. The Eh potentials of the contaminated aquifers were indicated by the presence of high H2 levels which is located in the center of the plume. The groundwater samples also exhibited high levels of oxygen, sulfate, methane and Fe(II) which act as potential electron acceptors for redox reactions.
