Hydrocarbons commonly contaminate aquifers and, in certain cases, can be successfully treated through biodegradation. Biodegradation is an effective technique for cleaning up pollution by enhancing pollutant-degrading bacteria in situ. However, in situ sampling for monitoring processes occurring into the ground during the treatment is expensive and invasive. In this article, an alternative method was tested. Spectral Induced Polarization (SIP) was combined with gas analyses, CO 2 concentration and its carbon isotopic ratio, to monitor toluene aerobic biodegradation in laboratory columns. Microbial activity was characterized by an evolution of the SIP response in correlation with a CO 2 production with the same carbon isotope signature as toluene. The spectral induced polarization response followed the variations of bacterial activity and displayed a phase shift up to 15 mrad. These results support the feasibility of using geophysical measurements, supported by CO 2

“…Previous studies have measured DC resistivity and IP anomalies at contaminant plumes caused by physical changes on the grain surface due to biofilm formation during microbial biodegradation and iron precipitates (Aal et al, ; Atekwana & Atekwana, ; Atekwana & Slater, ; Personna et al, ; Williams et al, ). In our study, we use the IP data to remove the effect of surface conductivity from the bulk conductivity, and this is possible under the assumption that the IP signal is controlled by the surface area of the sediments, and not by the presence of, e.g., biofilms and/or iron precipitates.…”

Contaminant mass discharge is a commonly applied tool to evaluate the environmental impact of contaminated sites on water resources. At large contaminated sites with heterogeneous sources, such as landfills, the number of wells available is often not sufficient, leading to a high uncertainty of mass discharge estimates. In this study, we tackle the uncertainty of the contaminant mass discharge due to low sampling densities by interpolating limited water‐sample data with the support of surface direct current resistivity and induced polarization geophysical data. The method relies on finding a conceptual link between the bulk conductivity imaged from geophysics and the contaminant concentrations. We investigate the link between (1) imaged bulk and electrical water conductivity, (2) water conductivity and conservative ionic species, (3) water conductivity and redox‐sensitive species, (4) water conductivity and semipersistent organic species, and (5) water conductivity and biodegradable organic compounds. The method successfully identify similarities between the distribution of the bulk conductivity and chloride and pharmaceutical compounds in a landfill leachate plume and between the bulk conductivity data and benzene and chlorinated ethenes for a contaminant plume from a former pharmaceutical factory. Contaminant concentrations were interpolated through regression kriging, using geophysical data as the dependent variable. The distribution of concentration determined with the novel method showed a lower mean relative estimation error than the traditional method of kriging only contaminant concentration data. At large sites, the method can improve contaminant mass discharge estimates, especially if surface geophysical measurements are integrated in the site investigation at an early stage.

This paper provides an update on the fast‐evolving field of the induced polarization method applied to biogeophysics. It emphasizes recent advances in the understanding of the induced polarization signals stemming from biological materials and their activity, points out new developments and applications, and identifies existing knowledge gaps. The focus of this review is on the application of induced polarization to study living organisms: soil microorganisms and plants (both roots and stems). We first discuss observed links between the induced polarization signal and microbial cell structure, activity and biofilm formation. We provide an up‐to‐date conceptual model of the electrical behaviour of the microbial cells and biofilms under the influence of an external electrical field. We also review the latest biogeophysical studies, including work on hydrocarbon biodegradation, contaminant sequestration, soil strengthening and peatland characterization. We then elaborate on the induced polarization signature of the plant‐root zone, relying on a conceptual model for the generation of biogeophysical signals from a plant‐root cell. First laboratory experiments show that single roots and root system are highly polarizable. They also present encouraging results for imaging root systems embedded in a medium, and gaining information on the mass density distribution, the structure or the physiological characteristics of root systems. In addition, we highlight the application of induced polarization to characterize wood and tree structures through tomography of the stem. Finally, we discuss up‐ and down‐scaling between laboratory and field studies, as well as joint interpretation of induced polarization and other environmental data. We emphasize the need for intermediate‐scale studies and the benefits of using induced polarization as a time‐lapse monitoring method. We conclude with the promising integration of induced polarization in interdisciplinary mechanistic models to better understand and quantify subsurface biogeochemical processes.
