“…The suitability of the groundwater for drinking was evaluated by comparing the values of different water quality parameters with those of the World Health Organization (WHO 2006) and European Standards guidelines values for drinking water (European Communities 1998). Suitability of the surface and groundwater for irrigation was evaluated based on SAR (Richards 1954), EC, and Na % (Ragunath 1987). ArcMap 10 was used as geographic information system for mapping purpose.…”

“…The Na % indicates that all water samples are suitable for irrigation, and 45.7, 34.2, and 20.1 % of them are classified under excellent, good, and permissible category, respectively [according to Ragunath classification (1987)] ( Table 6). The classification of water samples with respect to the EC (Ragunath 1987) shows that the majority of the samples (97 %) are classified as good. Plotting the water samples in a Wilcox diagram (Fig.…”

However, the salinity hazard is ruled out due to the high Table 6 Suitability of water for irrigation based on SAR (Richards 1954), EC and Na % (Ragunath 1987) …”

“…In addition, human activities such as industrialization, agriculture, mining, and urbanization produce effluents affect groundwater quality Singh et al 2012;Oyarzún et al 2015). Normally, groundwater contamination occurs gradually with little impact in the initial period of deterioration, but if it is not controlled at the right time, this water may not be suitable for any purpose for a long time (Rao et al 1997). In recognition of this, the importance of regular monitoring of groundwater is underlined, especially when there are significant changes in industrial, agricultural, and urbanization activities.…”

This study evaluates the groundwater suitability for drinking and agricultural purposes and assesses the hydrochemical evolution in Al-Khazir Gomal Basin, north of Iraq. Sixty groundwater samples and 10 river water samples were collected in the dry season (October) and wet season (April). The samples were analyzed to determine major and some minor ions, trace elements, and physicochemical properties. All surface and groundwater samples are considered as fresh water (TDS \ 794 mg/L) and slightly vary in chemical composition. The abundance of the major ions is as follows:Interpretation of analytical data showed predominance, the water type of Ca-HCO 3 and Ca-Mg-HCO 3 indicated young and renewable groundwater. Total dissolved solid, total hardness, major ions, and trace elements are all within permissible limits of the potable and domestic purposes according to the European and WHO standards. The parameters of irrigation suitability showed that all of the samples are fit for irrigation purpose. Moreover, cluster and factor analyses were applied to the large data set (70 samples and 25 variables) to unravel the hidden relationships between the parameters, and to reveal the main factors affecting the water quality. The samples collected from the same well during the wet and dry season were clustered together indicating that the seasonal variability is negligible. Factor analysis showed that the rainfall leaching processes (recharge), carbonate minerals dissolution, aluminosilicate weathering, and ionic exchange are the dominant factors involved in controlling the groundwater chemical composition.

Geographic information system (GIS) has become one of the leading tools in the field of hydrogeological science that helps in assessing, monitoring, and conserving groundwater resources. Groundwater is a finite resource, which is being overexploited due to increase in demand over the years leading to decrease in its potentiality. In the present study, DRASTIC model has been used to prepare groundwater vulnerable zone in hard rock aquifer of granitic terrain. The main objective is to determine susceptible zone for groundwater pollution by integrating hydrogeological layers in GIS environment. The layers such as depth of aquifer, recharge, aquifer yield, soil type, topography, vadose zone, and transmissivity are incorporated in the DRASTIC model. The final output of the map shows that around 60% of the area falls under low to no risk of pollution zone. The high risk of pollution zones are mostly present towards the margin of southeastern periphery. The lower part of the basin as well as small area on northern side falls under moderate risk of pollution zone. For the assessment of groundwater pollution zone, 24 groundwater samples have been collected from different vulnerable zones. The chemical analysis of sample shows that the southeastern margin of basin has relatively high concentration of nitrate as compared to other parts of the basin. It is present in high pollution zone as well as moderate pollution zone. The present model can be used for assessment and management of groundwater.
