“…Non-invasive geophysical techniques, particularly electrical resistivity tomography (ERT), have emerged as invaluable tools for hydrogeological studies and the mapping of mine waste tailings [18][19][20][21][22]. ERT surveys have found widespread application in studies related to groundwater mapping [23][24][25][26] and the mapping of groundwater contaminants [27][28][29][30]. Within the realm of hydrogeological investigations, electrical methods have consistently proven to be the most employed geophysical technique [31,32].…”

Mining activities often leave behind a legacy of environmental challenges, with aging tailings ponds representing a significant concern due to their potential for leachate formation and subsequent contaminant release. Thus, this study employs Electrical Resistivity Tomography (ERT) to investigate the intricate pathways of leachate within an aging mining tailings pond, addressing the pressing environmental and human health concerns associated with potential contaminant release. Ten 2D ERT profiles were acquired at the El Mochito mine waste site, covering an area of approximately half a square kilometer. These profiles, ranging in length from 104 to 363 m, provided insights into subsurface conditions down to a maximum depth of 60 m. The subsurface mapping of the ERT data showed three different geoelectric layers. The uppermost layer, with a thickness of approximately 2.5 m and resistivity values ranging from 60 to 100 Ohm.m, was identified as a dry tailing/soil zone. Beneath it, the second layer exhibited moderately resistive values (30–60 Ohm.m) with varying thicknesses of 10–20 m, signifying a percolation/leaching zone (semi-saturated zone). The third layer, characterized by substantially low resistivity (1–30 Ohm.m), indicated saturation and the presence of conductive materials, strongly suggesting active leaching. Based on these findings, this study recommends further investigation through geochemical analysis of subsurface samples and more advanced geophysical imaging techniques to validate the distribution of anomalous zones and delineate remediation pathways. This study lays the foundation for future comprehensive research that will integrate geophysical surveys with geochemical analysis and establish 4D modeling techniques to monitor pollutant penetration over time, with a particular focus on mine waste tailings mapping. Plus, this study contributes valuable insights into the characterization of leachate pathways within mining tailings ponds, offering a foundation for informed environmental management and remediation strategies.

“…The human and environmental impact of the exploration activities of these natural resources has been a subject of debate in the national discourse. However, research findings in recent times have revealed that the rural dwellers and oil field workers in the region are continually exposed to radiation hazards from gamma radiation and internal exposure resulting from the inhalation of radon gas from gas flairs, radiation from industrial radiography, automated ionizing radiation gauge, well logging, use of radiotracers in pipes, mapping and evaluation of geological formation [1][2][3][4] . Ironically, most of these studies are restricted to the onshore area of the Niger Delta Region leaving the swamp/coastal areas unreached due to lack of ease of access occasioned by the difficult nature of the terrain.…”

Background and Objective:The occupational risks associated with exposure from radioactivity concentration of soil from oil and gases producing coastal areas of Nigeria have been assayed after sixty years of exploration activities in the area, to ascertain the radiological impact on the oil field workers and host communities. This study observes the occupational risk from natural occurring radioactive materials in soil samples. Materials and Methods: Gamma spectrometric technique was used to determine the radiometric in the soil samples collected using highly efficient thallium activated 3"×3" gamma spectrometer. Results: The mean activity concentration of the three natural radionuclides of 40 K, 238 U and 232
