Lack of correlation between organic acid concentrations and predominant electron-accepting processes in a contaminated aquifer
January 1, 1997
Long-term (1992-1995) monitoring data from a petroleum hydrocarbon- contaminated aquifer were used to examine the hypothesis that concentrations of low molecular weight (LMW) aliphatic organic acids reflect terminal electron-accepting processes. During the period of study, concentrations of dissolved hydrogen (H2) indicated that methanogenic, sulfate-reducing, and iron(III)-reducing conditions predominated at the site. However, there was no correlation between LMW organic acid concentrations and concentrations of dissolved H2. These results indicate that organic acid concentrations are not a reliable indicator of local redox conditions at this site.
