“…Numerous studies have been conducted in various parts of India in determining the groundwater contamination and their sources of pollution (Lakshmanan et al 2003;Shankar et al 2008;Rao et al 2011;Brindha & Elango 2012;Selvakumar et al 2017;Acharya et al 2018;Chaurasia et al 2018;Dhawde et al 2018;Adimalla & Qian 2019). Various models have been implemented for assessing groundwater vulnerability and to identify the risk zones across the country (Khan et al 2010;Alam et al 2014;Bhuvaneswaran & Ganesh 2019;Bera et al 2021) to highlight the requisite of groundwater management plans and protection measures. Hence, effective regulation and reclamation of the ecological environment polluted by toxic elements and heavy metals have become a serious scientific issue affecting the health and development of the economy.…”

Rapid urbanization and industrialization leading to an increase in groundwater contamination is a serious environmental concern in India in recent years. The risk of groundwater contamination is highly pronounced in and around the Ranipet industrial area causing a threat to human health and a balanced ecosystem. In this study, 40 groundwater samples were collected in and around the industrial area of Ranipet which is largely producing Chromium (Cr) and Chromium-based chemicals. The heavy metal contamination and water quality index (WQI) were evaluated to determine groundwater quality and related human health risk assessment using the model proposed by the USEPA for adults. Based on the WQI range, it is found that more than 50% of groundwater samples are poor and non-potable. Also, the concentration of heavy metal Chromium in the groundwater exceeded the acceptable limit, i.e., 0.05 mg/L. The human health risk assessment indicates that the chronic daily intake of groundwater for the adult in the study area is in the order of Cr > Fe > Pb > Cd indicating chronic toxicity. It was also observed that the carcinogenic risk is higher than the acceptable limit (1 × 10−6) as a result of higher Chromium intake via ingestion. The outcome of the present study will support the stakeholders in decision-making toward regional sustainable groundwater management.

“…An aquifer's nature and flow rate are determined by its media, which also determines the route and path length of the pollutant (Bhuvaneswaran and Ganesh 2019). Furthermore, the aquifer media factor is crucial to salinity's movement in groundwater as they provide interconnected pore spaces facilitating solute movement (Shakoor et al 2020).…”

“…The vadose zone (the unsaturated area between the ground surface and the water table) impacts the speed of pollutant migration into an aquifer (Saida et al 2017). The type of material that constitutes the vadose zone influences groundwater pollution mechanisms, including biodegradation, mechanical filtration, sorption, volatilization, and dispersion (Bhuvaneswaran & Ganesh 2019). In addition, the vadose zone's influence on groundwater's vulnerability is a combination of topography and the aquifer media (Shakoor et al 2020).…”

This study evaluated the susceptibility to groundwater pollution using a modified DRASTIC model. A novel hybrid multi-criteria decision-making (MCDM) model integrating Interval Rough Numbers (IRN), Decision Making Trial and Evaluation Laboratory (DEMATEL), and Analytical Network Process (ANP) was used to investigate the interrelationships between critical hydrogeologic factors (and determine their relative weights) via a novel vulnerability index based on the DRASTIC model. The flexibility of GIS in handling spatial data was employed to delineate thematic map layers of the hydrogeologic factors and to improve the DRASTIC model. The hybrid MCDM model results show that net recharge (a key hydrogeologic factor) had the highest priority with a weight of 0.1986. In contrast, the topography factor had the least priority, with a weight of 0.0497. A case study validated the hybrid model using Anambra State, Nigeria. The resultant vulnerability map shows that 12.98% of the study area falls into a very high vulnerability class, 31.90% falls into a high vulnerability, 23.52% falls into the average vulnerability, 21.75% falls into a low vulnerability, and 9.85% falls into very low vulnerability classes, respectively. In addition, nitrate concentration was used to evaluate the degree of groundwater pollution. Based on observed nitrate concentration, the modified DRASTIC model was validated and compared to the traditional DRASTIC model; interestingly, the spatial model of the modified DRASTIC model performed better. This study is thus critical for environmental monitoring and implementing appropriate management interventions to protect groundwater resources against indiscriminate sources of pollution.

“…To name a few, in India, there is a study on "The In-Depth Evaluation of the DRASTIC Index for the Study of Groundwater Vulnerability to Pollution in the Semi-Arid Vattamalaikarai River" (Arya and al., 2020). Within the same country, there is an academic research on "The Spatial Assessment of Groundwater Vulnerability by The DRASTIC Model In The Uppar Odai Subwatershed, Na Ndiyar, Cauvery Basin, Tamil Nadu, India" (Bhuvaneswaran and Ganesh, 2019). In Egypt, researchers have conducted a case study named "The Assessment of Groundwater Quality in The El Fayoum Depression by The DRASTIC Model" (Gad and El-Hattab, 2019).…”

the DRASTIC method was chosen because it can be adapted to different environments and because it combines the seven criteria that directly influence groundwater: depth, recharge, geology, soil, slope, unsaturated zone and conductivity. Located in the North West of Morocco, the Temara aquifer is a very important water resource, but it is overexploited and deteriorated as never before. This issue is of concern to decision-makers in the field of water management. The objective of this work is to create a map of vulnerability to pollution by the Bay of Geographic Information Systems (GIS) and the DRASTIC model. Thus, the highest vulnerabilities are located around the drinking water treatment plant of Ain Atiq, at the mouth of the Bouregreg River and scattered in places throughout the study area. The results of the physico-chemical analysis showed compatibility with the results of the DRASTIC model.
