“…Transfer of the sulphide oxidation products: Zn 2+ , Cd 2+ , Pb 2+ , Mg 2+ , Ca 2+ and SO 4 2− change the electrical conductivity of the rock mass (Schön 2015). Therefore electrical resistivity and electromagnetic methods are successfully used to identify zones of acid drainage related to exploitation and processing of metal ores (Vanhala et al 2004;Chouteau et al 2006;Cabala et al 2008;Iacob and Orza 2008;Gómez-Ortiz et al, 2010;Nearing et al 2013;Acosta et al 2014;Olenchenko et al 2016;Epov et al 2017) and of hard coal (Ladwig 1983;Pierwola and Kowalska 2012;Pierwoła 2013;Power et al 2018).…”

Long-term underground exploitation of Zn-Pb ores has led to drainage of the area and formation of a huge dumping ground in the form of a pile. In its vicinity, processes of acid drainage have developed as a result of contamination of soils and groundwater. Geochemical transformations of mineral contents of waste can significantly affect physical and chemical properties of the soils and the bedrock. At the prospect of termination of the mining activity in the near future, determining the routes of the pollution migration, ability to monitor acid drainage processes and assessment of the risk of heavy metal pollution are really crucial. The paper presents a proposal for solving this problem by means of geophysical methods: Electrical Resistivity Tomography (ERT), Time Domain-Induced Polarisation (TDIP), Frequency Domain Electromagnetics (FDEM) and shallow-depth magnetometric surveys combined with geochemical investigations. The obtained results of geophysical surveys have been confirmed by geochemical investigations. The applied ERT and TDIP methods make it possible to identify the spread of the zones of pollution around the tailing pile, but their effectiveness depends on humidity of the ground. Soil magnetometry and shallow-depth induction profiling are a good tool to identify the medium contaminated with minerals redeposited by aeolian processes and allow to determine the range of the dust spread from the pile. It has been shown that the range of impact of the geochemical changes around the tailing pile is high and depends not only on directions and dynamics of water flow from the pile but also on aeolian transport.

“…Various applications of the ERT method have been presented over the past two decades for: hydrogeological studies (Clément et al, 2014; Hübner et al, 2017, 2015; Nimmer et al, 2008), agricultural applications (Cassiani et al, 2012; Michot et al, 2003; Uhlemann et al, 2016b), ground water resources (Binley et al, 2002; Kuras et al, 2009), tracer and contaminant plume monitoring (Audebert et al, 2016a, 2016b; Koestel et al, 2009, 2008; Kuras et al, 2016, 2014; Power et al, 2014; Rucker et al, 2011; Wilkinson et al, 2010), geotechnical applications (Chambers et al, 2014, 2015; Uhlemann et al, 2016a, 2017) and mining environmental issues (Anterrieu et al, 2010; Dimech, 2018; Dimech et al, 2018, 2017; Intissar, 2009; Power et al, 2018).…”

Core Ideas 3D time‐lapse ERT is used to monitor water infiltration for mining environmental issues. Geoelectrical images provide information where no hydrogeological data is available. Water resistivity must be taken into account to understand bulk resistivity variations. Electrical resistivity of water is used as a tracer to reconstruct water infiltration. Infiltration model integrating both hydrogeological and geophysical data is proposed. Open‐pit mines often generate large quantities of waste rocks that are usually stored in waste rock piles (WRPs). When the waste rocks contain reactive minerals (mainly sulfides), water and air circulation can lead to the generation of contaminated drainage. An experimental WRP was built at the Lac Tio mine (Canada) to validate a new disposal method that aims to limit water infiltration into reactive waste rocks. More specifically, a flow control layer was placed on top of the pile, which represents a typical bench level, to divert water toward the outer edge. Hydrogeological sensors and geophysical electrodes were installed for monitoring moisture distribution in the pile during infiltration events. A three‐dimensional (3D) time‐lapse hydrogeophysical monitoring program was conducted to assess water infiltration and movement. Readings from the 192 circular electrodes buried in the WRP were used to reconstruct the 3D bulk electrical resistivity (ER) variations over time. A significant effort was devoted to assessing the spatiotemporal evolution of water ER because the bulk ER is strongly affected by water quality (and content). The water ER was used as a tracer to monitor the infiltration and flow of resistive and conductive waters. The results indicate that the inclined surface layer efficiently diverts a large part of the added water away from the core of the pile. Local and global models of water infiltration explaining both bulk and water ER variations are proposed. The results shown here are consistent with hydrogeological data and provide additional insights to characterize the behavior of the pile.

“…After the current is turned off, the potential decay in the ground is measured again in one or several time windows. A common parameter used to quantify the TDIP measurements is the chargeability, which is defined as the ratio of the secondary potential over the primary potential of the transmitted current (Magnusson et al 2010;Olsson et al 2015;Power et al 2018;Revil et al 2015;Slater and Lesmes 2002;Sumner 2012). Dividing the chargeability with the measured resistivity yields the normalized chargeability, which can highlight areas with high surface conductance properties (Magnusson et al 2010;Slater and Lesmes 2002).…”

In Bolivia climate change and anthropogenic activities such as extensive agriculture, industries and urbanization have increased the groundwater demand and extraction, which is leading to severe stress on groundwater resources in several regions of Bolivia. This research aims to present an overview of different geophysical surveys performed in Valle Alto (central Bolivia), in particular in the Punata and Toco alluvial fans. The application of geophysics can have an implication in broadening the knowledge about local aquifers, which later might assist in proposing sustainable groundwater exploitation and protection plans. The geophysical results revealed two similar aquifer systems contained in unconsolidated sediments. A refinement of the hydrogeological conceptual models in terms of layering, lateral variation and thicknesses was performed in both areas. Moreover, geophysical surveys revealed geological features such as faults and saline regions which have not been reported previously in other studies. Such information is aimed to be the basis for further debates on groundwater protection, management, planning, and decision-making between local water user organizations and municipalities.
