“…In this regard, several studies have already remarked the high concentrations of PTEs in soils, sediments, and water bodies near mining sites and waste deposits in the Iberian Pyrite Belt [3,[8][9][10]. Drainage networks and groundwater environments have been found to be especially vulnerable to contamination by the release of PTEs from waste deposits [11], and their accumulation in flora and fauna can entail huge environmental problems [12][13][14][15][16].…”

“…Because of this, the characterization and evaluation of derelict mine wastes has become a growing concern among the scientific community, especially in regions where large quantities of wastes have been stored or abandoned [12,[17][18][19][20][21]. Commonly, the characterization of soil and sediment PTE contamination is based on the determination of the PTE total contents.…”

The geochemical characterization of the mine deposits and soils in metal mining areas is essential in order to develop an effective mine reclamation strategy. The determination of total potentially toxic element (PTE) content, together with the application of chemical extraction procedures, can give insight into the behavior of contaminants after the application of different mine reclamation solutions, as well as identify the areas where urgent action is needed. This work presents a practical application to the evaluation of the pollution potential of trace elements in soils affected by mining activities, to be used in metallic mine reclamation. The PTE behavior was assessed by single extractions in order to simulate four environmental conditions: PTE mobility under rainfall conditions, acid mine drainage, reducing conditions, and plant uptake. The spatial distribution of contaminants in the study area was evaluated by determination of PTE total content in soil samples. Trace elements with high natural mobility, such as Zn, appeared concentrated at water and sediment discharge areas, while As, Pb, and Cu contents were higher near the mine wastes. The results obtained after the extractions suggested that the highest PTE content was extracted in the complexing–reducing medium, due to the dissolution of secondary sulfates and Fe3+ oxyhydroxides and the subsequent release of PTEs associated with those mineral phases. Reclamation strategies applied in the study area should promote efficient water drainage, infiltration, and subsuperficial water circulation in order to maintain oxidant conditions in the soil. The methodology applied in this study may constitute a valuable tool to define the geochemical constraints in metal mining areas, as well as help to develop appropriate mine reclamation solutions.

“…Geoelectrical methods -especially DC resistivity methods -rely on the diversified electrical resistivity of different media and can easily facilitate and quickly recognize the geological structure, thus determining the condition of the nearsurface zone. These methods, including the electrical resistivity tomography (ERT) method, are frequently used for engineering and environmental surveys [1][2][3][4][5][6], especially those surveys of groundwater zones in the vicinity of waste disposal sites [7][8][9][10][11][12][13][14][15][16][17]. In particular, the vertical electrical sounding (VES) method is a promising approach that is discussed in this article.…”

“…ERI has been used in multiple mined land hydrological investigation studies, however never before on coal MTM. Previous noncoal applications include open pits (Ramalho, Carvalho, Barbosa, & Monteiro Santos, 2009), tailings impoundments and dams (Buselli & Lu, 2001;Grangeia, Ávila, Matias, & Ferreira de Silva, 2011;Martín-Crespo, Martín-Velázquez, Gómez-Ortiz, Ignacio-San José, & Lillo-Ramos, 2010), and a capped waste rock repository (Wangerud, Versteeg, Heath, Markiewicz, & Richardson, 2006). ERI has also imaged polymetallic mine spoil structure (Anterrieu, Chouteau, & Aubertin, 2010) and Karst conduits (Sawyer, Zhu, Currens, Atcher, & Binley, 2015).…”

Surface coal mining has altered land cover, near‐surface geologic structure, and hydrologic processes of large areas in central Appalachia, USA. These alterations are associated with changes in water quality such as elevated total‐dissolved solids, which is usually measured via its surrogate, specific conductance (SC). The SC of valley fill effluent streams is a function of fill construction methods, materials, and age; yet hydrologic studies that relate these variables to water quality are sparse due to the difficulty of conducting traditional hydrologic studies in mined landscapes. We used electrical resistivity imaging (ERI) to visualize the subsurface geologic structure and hydrologic flow paths within a valley fill. ERI is a noninvasive geophysical technique that maps spatiotemporal changes in resistivity of the subsurface. We paired ERI with artificial rainfall experiments to track infiltrated water as it moved through the valley fill. Results indicate that ERI can be used to identify subsurface geologic structure and track advancing wetting fronts or preferential flow paths. Our results suggest that the upper portion of the fill contains significant fines, whereas the deeper profile is primarily large rocks and void spaces. Water tended to pond on the surface of compacted areas until it reached preferential flow paths, where it appeared to infiltrate quickly down to >15 m depth in 75 min. ERI applications can improve understanding of how fill construction techniques influence subsurface water movement, and in turn may aid in the development of valley fill construction methods to reduce water quality effects.
