“…The main strength of the DRASTIC method is the possibility of including or eliminating parameters or factors from the model to adapt to different problems, such as the conditions in the area of study and availability of data [45,75,82]. Alternatively, the weight and rate scores can be modified depending on the field measurement data, whereas susceptibility and risk maps can be combined to provide better results using DRASTIC [51].…”

Over the last three to four decades, several methods for assessing groundwater vulnerability to anthropogenic pollution have been developed. Researchers and policymakers have widely used these methods for preventing groundwater pollution through knowledge about particularly vulnerable areas. This systematic review presents different and significant methods for assessing the vulnerability of aquifers for the protection of the resource. Previous studies mentioned that formulating a single technique for assessing groundwater vulnerability is difficult; thus, different methods and techniques have been proposed. Therefore, this paper presents three methods, namely, DRASTIC, GOD, and susceptibility index (SI), which will be discussed in detail, and highlights their advantages and limitations. In doing so, the study introduces the concept of aquifer vulnerability, and further discussion will be devoted to the three methods. Lastly, the study outlines the major challenges to the assessment of aquifer vulnerability. The review concludes the importance of groundwater vulnerability and strategies for preserving its quality.

Systematic assessment of groundwater suitability for irrigation purpose was evaluated in Korba district, Chhattisgarh, Central India. As a part of the assessment, groundwater physico-chemical data of 56 locations were considered. Ascertaining the groundwater suitability and its characteristics, various quality indices and hydrogeochemical studies were performed. Quality results showed that groundwater of the study area was mostly alkaline in nature, where a total of 17% groundwater samples were found hard to very hard, 9% were slight to moderate hazard, and 4% were high saline type. Chemical indices, namely Sodium percentage (Na%), Sodium adsorption ratio (SAR), Residual sodium carbonate (RSC), Permeability Index (PI), Kelly's ratio (KR) and Magnesium adsorption ratio (MAR) were evaluated. According to the computed indices, majority of the samples were found to be suitable for irrigation. Based on USSL plot, around 54% of samples fell in C 1-S 1 and C 2-S 1 fields, indicating low to medium salinity with a low alkali hazard. Hence, groundwater fell under C 1-S 1 and C 2-S 1 fields can be used to irrigate all kind of soils with marginal increase of risk level for exchangeable Na + content. Results of hydrogeochemical model suggested that groundwater of the study area were mainly influenced by rock-water interaction phenomena. Groundwater hydrogeochemical facies was characterized through Piper plot and Chadha's diagram, which showed Ca-Mg-HCO 3 type groundwater as the dominating facies within the study region.

“…Groundwater contamination is one of the pressing environmental issues faced by the world today. Rapid population growth, urbanization, industrialization, intensive agriculture and many other anthropogenic activities pose serious threat to ground water resources (Kattaa et al,2010;Singha et al, 2019). In comparison to surface waters, groundwater is relatively less susceptible to contamination (Kumar et al, 2015;Jamrah et al, 2008;Pathak and Hiratsuka, 2011).…”

Groundwater vulnerability assessment techniques are useful tools in groundwater management. The purpose of the study is to assess the groundwater vulnerability of Kodoor river basin in Kerala by DRASTIC model and to modify the model to suit the regional scale by incorporating the land use and/ or land cover (LULC) pattern of the area of study in it to produce DRASTICA model. The interdependence of the nitrate concentration data and vulnerability indices from DRASTIC and DRASTICA models were calculated. Correlation coefficient values obtained for DRASTIC and DRASTICA model is 0.21 and 0.38 respectively which shows that the modified DRASTICA model suits the study area better. The study area was grouped into three zones based on the grades of vulnerability. The study also includes the sensitivity analysis of the DRASTICA model. The map removal sensitivity analysis and single parameter sensitivity analysis were carried out to validate the model results.
