“…This groundwater pollution poses risks to human and ecological health [30] . There are both natural and anthropogenic sources of groundwater contamination, and groundwater pollution can have long-term, complex, and insidious effects on human health that are not easily detectable [10], [33] . Groundwater contamination is a complex, long-term geological-geochemical process, and contaminated aquifers will require a protracted period to recover [21], [26], [38] .…”

There is growing evidence of increasing pollution threats to groundwater resulting from anthropogenic activities. Assessments of the risk of groundwater contamination are useful for preventing and controlling groundwater pollution. This study established a quantitative evaluation model based on the origin–pathway–target model. The target, guideline, and indicator layers were established through a comprehensive analysis of the distribution of pollution sources, hydrogeological conditions, and other conditions in the northeastern plain area of Beijing by applying the hierarchical analysis method. Each assessment index was quantified and analyzed based on the groundwater pollution risk assessment index system, and the risks associated with pollution sources, groundwater susceptibility to pollution, and groundwater value in the study area were evaluated. The comprehensive assessment results were superimposed by the matrix method and the pollution risk classification was conducted using the ArcGIS platform. Grade Ⅰ to Ⅴ pollution risk areas accounted for 12.5%, 28.5%, 23.2%, 26.1%, and 9.7% of the total area, respectively. The V pollution risk area was mainly in the central and northeastern part of the Beijing plain area and agriculture and industry were the main sources of pollution in the central and northeastern areas, respectively. The study area had a large net recharge, soils were dominated by sand and gravel, and there was a high permeability coefficient. The study area also showed poor groundwater pollution prevention performance, which resulted in the infiltration of pollutants into the groundwater environment. The V pollution risk area contained sensitive groundwater targets, and the pollution index, groundwater richness, annual average groundwater extraction, and risk of pollution were high.

“…This city has wellsprings of contamination, for example, land lls, risky sewer lines, squander lands result which leads to groundwater contamination. Inappropriately treated e uents, underground stockpiling tanks, spills, and draining of harmful synthetic compounds are the major sources of contamination and signi cantly in uence groundwater quality (Garewal and Vasudeo, 2018;Santucci et al 2018). It has been perceived that most of the industrial areas/towns release their e uents into the streams, and the solid waste created is discretionarily dumped on open land along lanes and lakes (Krishna and Mohan 2014;Vaiphei and Kurakalva 2021a).…”

Anthropogenic activities such as the rapid leap of industrialization and urbanization constitute a significant concern in megacities and have become a key source of groundwater contamination. Twenty-five (25) groundwater samples were collected from tube wells and handpumps from Nacharam watershed, greater Hyderabad. The water samples were analyzed for 13 physicochemical parameters and major dissolved ions using the standard methods. WQI has been computed using a weighted arithmetic index method and integrated with GIS to identify the hotspots of contamination and their spatial distribution. The analytical data plotted on the Piper diagram showed that dominance of Ca-Mg-Cl (52%) type followed by Na-Cl type of water is dominant in 44% of samples might be resulting due to increase in anthropogenic activities such as discharge of waste water from industries. Results reveal that 96% of the samples exceed the F - concentrations compared with WHO permissible limits suggested unfit for drinking. WQI values indicate that 56% of samples fall in the poor category, 28% belong to very poor water, and 4% are unsuitable for drinking. These findings will provide valuable information to policymakers and stakeholders on the proper management and supply of potable water that reduces human health concerns .

“…Groundwater quality in aquifers is mainly controlled by two factors: (1) natural processes related to the aquifer including lithology, recharge quality, groundwater flow, residence time and soil/rock interactions with water (Ledesma-Ruiz et al, 2015;Walter et al, 2017); and (2) anthropogenic activities including agricultural practices, industrial wastewater discharges, domestic sewage practices, dumping sites, animal wastes, etc. (Böhlke, 2002;Erostate et al, 2018;Garewal and Vasudeo, 2018;Hudak, 2000;Lu et al, 2008;Nolan, 2001;Singh et al, 1995;Stigter et al, 1998). Due to the shallow depth of groundwater in coastal aquifers, surface anthropogenic contamination sources play a major role in groundwater contamination in these aquifers (Ntanganedzeni et al, 2018).…”
