ABSTRACT This paper provides an update on the fast‐evolving field of induced polarization method applied to biogeophysics. It emphasizes recent advances in understanding signals stemming from biological materials and their activity, points out new developments applications, identifies existing knowledge gaps. The focus this review is application study living organisms: soil microorganisms plants (both roots stems). We first discuss observed links between signal microbial cell structure,...
A bioelectrochemical system was developed to facilitate biodegradation of an organic contaminant (propylene glycol) using a sandbox containing iron bar that crossed the capillary fringe. In days following introduction contaminant, strong negative electric potential anomaly (on order −35 50 mV) observed at top surface sandbox, evidencing transport electrons in metallic and degradation contaminant. The served transmit between electron donor (i.e., propylene oxygen used as terminal acceptor....
Summary Understanding water and contaminant transport in the unsaturated zone is highly challenging due to spatial variability. Sufficient characterization of temporal distribution requires measurements solute fluxes at multiple locations with high resolution. Solute monitoring often limited observations resident concentrations, while flux concentrations govern movement solutes soils. We developed a new instrument, which combines multi-compartment sampling electrical resistivity techniques,...
Summary Agriculture, industry, airport activities all have impact on the quality of soil and water. To improve risk assessment, monitoring, design implementation cost-effective preventive or mitigation measures and/or policies we require a better understanding underlying environmental processes. Spatial heterogeneity plays critical role for describing water solute transport processes in unsaturated zone. Heterogeneous flow soils is complex challenging to quantify due changes hydraulic...
Summary Common redox potential sensors provide point measurements and are error prone. Destructive sampling can cause contact with air which will influence the state. Hence, assessing conditions in soil is challenging. Redox sensitive reactions like degradation of organic contaminants change water chemistry geophysical properties. We explored techniques ERT SIP to observe processes Propylene Glycol (PG), a de-icing chemical used at airports. Two laboratory experiments were performed monitor...
Summary Soil contamination of organic origin is a major environmental challenge. One the most common reactions in nature electron exchange between chemical species, also known as reduction-oxidation (redox) reaction. Redox drive matter degradation ground. Monitoring these therefore needed to protect soil and groundwater. This work aims provide non-invasive monitoring methods study redox state changes that occur near-surface interface, at boundary aerobic anaerobic conditions, well potential...
