“…These techniques utilize physical principles to map and characterize subsurface properties, providing valuable information without the need for direct excavations or sampling. Through geophysical methods, it is possible to obtain data on the geological structure, lithological changes, bedrock topography, groundwater levels, delineation of contamination plumes, and monitoring these plumes to evaluate the existence of biodegradation and to oversee the progress of the remediation process (Braga, 2016, Martinho, 2023. This information is essential for a more comprehensive understanding of the environment, enabling informed decision-making in environmental management projects and the remediation of contaminated areas.…”

Investigation of soil and groundwater contamination is essential for assessing environmental risks and monitoring remediation processes. Geophysical methods effectively map and characterize subsurface properties without requiring direct excavations. These methods provide data on geological structure, lithological changes, groundwater level, contaminant identi cation, and remediation process monitoring.Being non-invasive, they offer an advantage over drilling operations by avoiding the need for soil excavation. This reduces the risk of contaminant migration during investigation activities. The study area in São Paulo corresponds to a former industrial galvanization site where contamination by chlorinated solvents, especially tetrachloroethylene, occurred. Remediation measures such as pumping and treatment, multiphase extraction, soil/waste removal, and chemical oxidation were implemented in the area. The contaminant and remediation processes alter the geophysical signatures of the environment, enabling the use of the electrical resistivity method. However, applying this method can be challenging in urban areas due to pavement and urban interferences. The resistive-capacitive method was employed, allowing continuous data acquisition over large areas without the need to insert electrodes into the soil.Additionally, traditional electrical pro ling and induced polarization were used to gather data at greater depths. The integration of geophysical methods with soil sample descriptions in liners provided an analysis of subsurface characteristics and affected areas. Although challenges exist in applying it to urban areas due to pavement and interferences, the electrical resistivity method can contribute to the Conceptual Site Model by lling data gaps between wells and delineating the contaminant's in uence area and the chemical oxidation remediation process.

“…In the specific case of landfills, geoelectrical surveys are often employed to determine the variations in water content, salinity, and temperature within the waste massif, the leachate impact on aquifers, and mapping biogeochemically active zones with the presence of gas (Belghazal, Piga, Loddo, Messari, & Touhami, 2013;Bichet, Grisey, & Aleya, 2016;Costanzo-Alvarez et al, 2022;Dumont et al, 2016;El-Salam & Abu-Zuid, 2015;Flores-Orozco, Gallistl, Steiner, Brandstätter, & Fellner, 2020). Geoelectrical surveys combined with soil and borehole water quality (WQ) analyses in standard practices for characterizing and monitoring contaminated sites have been used successfully in Brazil (Lopes et al, 2012;Martinho, 2023;Porsani et al, 2004;Souza Teixeira et al, 2010). The magnetic method has been used in landfill studies in the search for buried magnetic materials such as barrels, pipes, or construction and demolition waste enriched in ferrous materials (French, Williams, & Foster, 1988;Gibson, Lyle, & George, 1996;Marchetti, Cafarella, Di Mauro, & Zirizzotti, 2002;Santos, Mateus, Figueiras, & Gonçalves, 2006).…”

Multiple geophysical methods are efficient for mapping the geometry of old waste dumps, detecting illegally buried waste, identifying areas enriched in leachate and biogas in landfills, and mapping contaminated sites. This paper describes the results of an electrical resistivity tomography (ERT) and magnetometric (MAG) investigation into the extensive dumping of construction and demolition waste installed in a former quarry in Northeast Brazil. Preliminary investigations using a geotechnical survey in the upper portion of the waste massif indicated the occurrence of methane gas, possible leachate at depth, concrete blocks with iron rebar, and even other metals in smaller proportions. The modeling of resistivity and magnetic data was used to delineate volumes containing metal, corresponding to low electrical resistivity values and high magnetic susceptibility. On the other hand, high resistivity measurements and low magnetic susceptibility are associated with gas or compacted and unsaturated terrain. From deep environmental drilling services and excavations in the region under study for the implementation of a subway, it was confirmed that the geophysical anomalies interpretation identified the presence of portions rich in organic matter, with high humidity, inside the dump and the presence of methane, concrete blocks, and ferrous material derived from the demolition of the construction industry.

“…The former is expensive, complex, time-consuming, and destructive to the soil structure; the latter has poor accuracy and resolution and does not allow for quantitative analysis of contaminated areas. Common physical methods for detecting heavy metal contamination sites include ground-penetrating radar [9], electromagnetic [10], resistivity [11], and excitation [12]. Ground-Penetrating Radar (GPR) method is not applicable to the detection of environments containing clay, saline groundwater, and sandy clay strata.…”

In order to reveal the migration process of chromium-contaminated sites, COMSOL5.6 software was used to build the initial model of the chromium pollution source and analyze the migration change characteristics over time based on the rule of groundwater movement and Convection–Dispersion equation. COMSOL provides fully coupled multiphysics modeling for most engineering fields. The results show that: the permeable layer with a high permeability coefficient during the migration of chromium pollutants has a strong adsorption effect on the heavily polluted part, and it will enhance the lateral diffusion of the polluted area within a short period. Based on the migration model, the intermediate gradient and the symmetrical quadrupole sounding model are built. The variation law of apparent amplitude frequency and apparent resistivity under flat and undulating terrain is analyzed based on the dual frequency IP (Induced Polarization) method. The results show that: The intermediate gradient detection is better than the symmetrical quadrupole sounding in the correspondence between the peak value of apparent amplitude frequency and the valley value of apparent resistivity. The arrangement of the bathymetric measurement point in the center of the projected edge of the pollution field can be a better way to monitor the pollution. Monitoring with the intermediate gradient detection device and the symmetrical quadrupole sounding device creates “multiple peaks” in the curve as it passes through the valley. Arranging the power supply electrodes on the mountain frontiers on both sides of the raised peaks and synthesizes the apparent amplitude frequency and apparent resistivity curves of the pollution field, which can effectively determine the specific orientation of the heavily polluted area of the pollution field. This research makes theoretical additions to the migration characteristics of the Cr pollution field. It provides technical guidance for the real-time monitoring of the pollution field, which is of positive significance for promoting ecological and environmental protection.
