Abstract In this article, a valuable approach utilizing the relationship between select physical water and soil characteristics and geoelectrical resistivity data was used to recognize and trace groundwater contamination by using the geoelectrical resistivity data of a landfill area. It can reduce uncertainty in geoelectrical resistivity interpretation. By interpreting and calibrating the resistivity model with the lithology and physical characters of water samples, it was possible to identify the unique paths of landfill leachate that occurred throughout a shallow aquifer. The water physical property analysis showed that the landfill area was contaminated by a relatively high amount of total of dissolved solids (TDSs). A scatter plot of TDS values and directly measured resistivity showed that resistivity decreased with increasing TDSs. The movement direction of the landfill leachate in the aquifer system was clearly observed in a depth slice of the resistivity distribution. The aquifer is considered to be contaminated starting from the landfill zone and extending to the northeastern part of the study area.

Introduction Municipal solids are unwanted manufactured goods that have been used for certain activities. Municipal solid wastes comprise daily items that humans use, such as food, papers, packaging, clothing and bottles (Yunmei et al. 2017; Thitame et al. 2010). These waste products are generated from human activity and increase as the population of humans increases. These products are collected and sent to landfill disposal sites. The waste production percentage indicates the development of a country or a city. The generation of solid waste depends on several factors, such as the development of the country or city and the level of education and awareness of residents. The increase in waste generation has affected society and the environment. Furthermore, the amount of waste increases in parallel with industry activity. As a result, this type of activity has brought about an increase in waste generation and pollution (Rotich et al. 2006; Chiemchaisri et al. 2007). Several investigations on the impacts of landfill leachates have been published. Among these investigations are reports that landfill leachate is a major source of trace organic pollutants, and the pollutants that can significantly affect the quality of the surrounding environment (Clarke et al. 2015). Negi et al. (2018) successfully used heavy metals and microbiological indicators to define the quality of an environment that h
