“…Electrical resistivity tomography, often used with other geophysical methods, has been used to identify the contaminated zone around waste landfills (e.g., in Portugal, Nigeria, Brazil, Vietnam, Indonesia, Singapore, Malaysia, Saudi Arabia, and Poland) [23,[29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Reclaimed landfill areas are excluded from various development options including construction, while contaminated zones around such places have no such restrictions. The successful reclamation of landfills means that the old landfill visually fits in well with its surroundings, but soil and water contamination problems remain valid. Former landfills were built without properly preparing the land, which resulted in the migration of contaminants in groundwater for a long period after these landfills were closed, further resulting in the limited use of such areas, at least for some purposes. Due to the development of cities, landfills formerly located in suburbs are becoming a part of these cities. In order to optimally and safely use these spaces, knowledge regarding the quality of the soil and water environment is necessary. This article presents methodological considerations regarding the use of carbon and sulfur isotope methods to assess groundwater contamination around former municipal waste landfills, especially reclaimed municipal landfills. It has been shown that natural groundwater is characterized by low values of both δ13CDIC and δ34S (δ13CDIC from −20 to −10‰ and δ34S at approximately −5‰), whereas leachate-contaminated groundwater is characterized by high values of both parameters (δ13CDIC from −10 to + 5‰ and δ34S from +5 to +20‰). The aim of this article is to demonstrate that carbon and sulfur isotope methods extended via SWOT analysis are universal and reliable methods for assessing the migration of pollutants, thus facilitating decisions regarding management.

“…The poor strength is due to the low thickness of the protective clay layer since the shallower aquifers are more susceptible to contamination than the deeper ones. The areas with low protective capacity considered is a pathway for the surface contamination which may later spread along the flow path and cause groundwater quality deterioration [15].…”

This research employed electrical resistivity method to determine the protective capacity of groundwater aquifers in Bahri city. The protective capacity predicts the vulnerability of aquifers to surface and subsurface contamination. In this study, vertical electrical sounding (VES) technique using Schlumberger array was conducted to determine the thicknesses of the subsurface layers. The VES measurements and borehole lithological logs were jointly interpreted to decrease the uncertainty of the resulting models. Consequently, five geoelectrical layers including two aquifers were indicated. The product of VES models including true resistivity and thickness used to measure the Dar Zarrouk parameters. The total longitudinal conductance and transverse resistance were used to detect the protective strength and thus the vulnerability of groundwater aquifers. In general, the protective capacity of the overburdened sediments ranged from good to very good. Accordingly, the aquifer in the study region is indicated as naturally protected and ideal for groundwater extraction. However, a comprehensive groundwater quality investigation is recommended for the safe use of groundwater for human consumption.

“…Several studies have highlighted the effectiveness of ERT in identifying and determining the extent of leachate contamination in urban waste [21,22]. For instance, Akiang et al [23] applied ERT to identify the infiltration zones of leachate and map out the surface areas contaminated by leachate in an urban waste site. Similarly, Morita et al (2022) [24] demonstrated the successful use of ERT in identifying covered and uncovered zones and boundary zones within an exposed landfill.…”

The efficient management of slurry, which is a by-product rich in nutrients derived from feces, urine, cleaning water, and animal waste that stands out for its high concentration of nutrients such as nitrogen, phosphorus, and potassium, is of vital importance, highlighting the importance of slurry management in storage ponds, which. The Murcia–Spain region has an important number of pig farms. Hence, infrastructures dedicated to managing by-products are necessary to prevent environmental pollution and eutrophication of groundwater. The aim of a recent study was to evaluate the relationship between electrical values and geochemical parameters of pig slurry stored in a pond using ERT and geochemical analysis. In addition, the study was designed to monitor the pond to determine the geochemical characteristics of the slurry and to assess the risk of lateral contamination. The study results indicate a noticeable decrease in electrical resistivity values at 0.4 and 1.6 m depth in surveys 1 and 2. The reduction ranges from 50 to 100 percent. This paper presents a new method for monitoring slurry ponds using electrical resistivity tomography. This non-invasive method provides detailed information on the distribution and characteristics of the fluids, as well as a clear picture of the electrical resistivity of the subsurface.
