The environmental impacts of pig production are increasing, specifically, those related to the management and storage of slurry. Some possible effects are water pollution from nitrate and phosphate leaching, soil pollution from phosphorus (P) accumulation, heavy metals, and salinization in semi-arid regions. The increase in livestock production in the last few years in Spain has brought, as a consequence, the notorious increase in the number of farms and the increase in the production of slurry. Only in the Murcia region, the total number of pig farms amount to 1433 for 2021. The large quantity of pig farms affects the storage ponds required for accumulating the generated slurry. The electrical resistivity tomography (ERT) method is a geophysical technique applied to monitor water infiltration into the soil. In addition, ERT time-lapse measurements can be applied to monitor these subsurface hydrologic processes and pollution plumes ( Zhao et al., 2020 ). Therefore, the main objective of this study is to monitor a slurry storage pond using ERT, which is naturally impermeabilized, to determine the degree of impact of the slurry contamination on the subsoil through 3D modeling with EarthImager 3D Resistivity Imaging and Voxler v.4 software.
