DescriptionThe current focus on identifying and remediating contamination calls for further investigation into methods that can be used to efficiently characterize subsurface conditions and monitor degradation processes. The primary focus of this research is the latter. Electrical geophysical methods have been well documented as a tool to map aquifers and contaminant plumes, and the same principles that allow for those surveys to be successful allow for these methods to be beneficial for monitoring the progress of remediation. Chemical and physical changes in the subsurface, known to result from biodegradation processes, could be monitored using these methods in situ.
This research provides several examples of these methods being effective in monitoring biodegradation. Spectral induced polarization measurements collected over time in a column experiment demonstrate the sensitivity of the method to processes related to microbial induced oil break up, as a result of microbial enhanced oil recovery processes. In another study taking place over the course of approximately 18 months, a progressive decrease in the resistivity of a massive oil spill (Deepwater Horizon) impacted region was observed. Advanced analysis of resistivity variations within the imaged area showed that long-term decreases in resistivity were largely associated with the impacted sediments. Finally, self potential measurements collected at a mature oil spill site, where bioremediation is known to have occurred, showed a measureable, biogeobattery related, response. In all cases, these methods showed the sensitivity of electrical geophysical methods to biodegradation processes. This demonstrates the potential utility of these methods being used an effect monitoring tool to be used in complement with more invasive and expensive chemical/biological testing.
