Impact of hydrocarbon biodegradation on low frequency electrical properties of unconsolidated sediments


"The influence of biodegradation processes and subsequent physicochemical changes on the low frequency electrical properties (e.g., real and imaginary conductivity) of unconsolidated sediments was investigated in laboratory sand columns and core sediments retrieved from a hydrocarbon contaminated site. The low frequency electrical measurements were conducted using induced polarization (IP) method in the frequency range 0.1-1000 Hz. Biological, geochemical, isotopic analyses, scanning electron microscopy images and surface area measurements were conducted to help in the interpretation of the low frequency electrical measurements...The findings of this study illustrate the potential utility of low frequency electrical measurements for non-invasive monitoring of microbial activity at sites undergoing natural hydrocarbon degradation. The results of this study further suggest that the interpretation of geoelectrical data from near surface environments should consider effects of microbial processes"--Abstract, pages iv-v.
