“…CO 2 penetrates through earth and rocks and dissolves CO 3 2− to produce HCO 3 − ions (Flood, ; Balathandayutham et al, ). The presence of Ca 2+ in the water, which is dissolved from earth and rocks leading to the hardness of water, originates from geological units, and agricultural and industrial waste (Deshpande and Aher, ; Kumaravel et al, ). Aside from TDS and TH, the most dominant ion in the research area in the wet and dry seasons is SO 4 2− , and the one with the lowest concentration is K + .…”

In this study, the physical and chemical characteristics of wet and dry season groundwater quality parameters of 35 wells within the provincial boundaries of Sivas were used for calculations such as sodium adsorption ratio (SAR), Kelly's ratio (KR), sodium percentage (Na%), permeability index (PI), residual sodium carbonate (RSC) and magnesium hazard (MH), which are used in irrigation water quality ratings. Also, the irrigation water quality index (IWQI) was calculated for all groundwater sources within the study area. Groundwater quality parameters and the spatial distribution of the parameters calculated throughout the study were mapped using GIS, and irrigation water quality evaluation was performed in accordance with USA Salinity Laboratory diagram and irrigation water quality standards. The correlations between the irrigation water quality parameters were determined using Pearson correlation analysis. IWQI values showed that the majority of groundwater samples (45.7%) are in the ‘weak' (MR: medium rating) category for the dry season, whereas 42.9% of groundwater samples fall within the ‘very weak' (HR: high restriction) category for the wet season. © 2019 John Wiley & Sons, Ltd.

“…Similarly, the majority of samples (86%) from all aquifers in the Nawab Shah district, the plot fell into the rock dominance zone, while (14%) of the samples fell into the evaporation dominance zones (see Supplementary Figures S1C,D), indicating that rock-forming weathered minerals and infiltration of precipitation were the primary factors that influenced groundwater chemistry (Kumaravel et al, 2014). Some groundwater samples from the Nawab Shah fall in the evaporation dominance zone, demonstrating the impact of surface river water on the groundwater system, which could be possibly trapped during the sedimentation process (Mani et al, 2008), as well as the importance of evaporation in the depth zone of shallow groundwater.…”

Arsenic (As) contamination in drinking groundwater sources is a common environmental problem in Pakistan. Therefore, we collected a total of (n = 81) drinking groundwater samples from various groundwater sources, from two districts’ namely Ghotki (n = 44) and Nawab Shah (n = 37) of Sindh, Province, Pakistan. The current research aimed to investigate the hydrogeochemistry of groundwater with elevated arsenic (As), its effect on the health of local population living in the study area, potential sources of groundwater variables, and the suitability of groundwater for ingestion motive. The results showed that groundwater sample variables of both districts had moderate to high concentration levels. The cations concentrations were observed in decreasing order of Na+ > Ca+ > Mg+ > K+, for both districts, while anions abundance was HCO3− > Cl− > SO42− > F− > NO3− in the Ghotki, and HCO3− > SO42− > Cl− > NO3− > F− in the Nawab Shah, respectively. Arsenic (As) had low to high concentration levels in both districts, observed with average values of 10.1 μg/L and 21.0 μg/L in the Ghotki and Nawab Shah, respectively. The water type was mixed CaMgCl type in both districts, while the groundwater sources were saturated for CO3 minerals indicated by the saturation indices results. Principal component analysis showed the geogenic source of ion exchange, dissolution of minerals, weathering of host rocks and anthropogenic input of industrial activities, agricultural practices and domestic waste for groundwater contamination. The water quality index (WQI) exhibits that majority of groundwater samples (73.6% of Ghotki and 65.7% of Nawab Shah) were suitable for drinking. The non-carcinogenic risk (HQ) values of As were (>1) in groundwater samples of the Ghotki and Nawab Shah, while a high mean HQ value (8.78 × 100) was recorded for children in Nawab Shah. The carcinogenic risk (CR) values of As were significantly higher than the maximum threshold CR value (1 × 10–4). This study emphasized that monitoring strategies are substantially needed to mitigate the As contamination to reduce the potential health risk.

“…As compared to the analytical results with BIS (2012), ~ 14% of groundwater samples are located above the threshold limit. The main sources of Ca 2+ in drinking water come from geological units, agricultural wastes, and industrial wastes (Kumaravel et al 2014). Moreover, magnesium (Mg 2+ ) is another important contributor to water hardness and its contribution remarkably influences the chemistry of groundwater (Ahada and Suthar 2018).…”

In recent years, groundwater pollution has become increasingly a serious environmental problem throughout the world due to increasing dependency on it for various purposes. The Damodar Fan Delta is one of the agriculture-dominated areas in West Bengal especially for rice cultivation and it has a serious constraint regarding groundwater quantity and quality. The present study aims to evaluate the groundwater quality parameters and spatial variation of groundwater quality index (GWQI) for 2019 using the fuzzy analytic hierarchy process (FAHP) method. The 12 water quality parameters such as pH, TDS, iron (Fe−) and fluoride (F−), major anions (SO42−, Cl−, NO3−, and HCO3−), and cations (Na+, Ca2+, Mg2+, and K+) for the 29 sample wells of the study area were used for constructing the GWQI. This study used the FAHP method to define the weights of the different parameters for the GWQI. The results reveal that the bicarbonate content of 51% of sample wells exceeds the acceptable limit of drinking water, which is maximum in the study area. Furthermore, higher concentrations of TDS, pH, fluoride, chloride, calcium, magnesium, and sodium are found in few locations while nitrate and sulfate contents of all sample wells fall under the acceptable limits. The result shows that 13.79% of the samples are excellent, 68.97% of the samples are very good, 13.79% of the samples are poor, and 3.45% of the samples are very poor for drinking purposes. Moreover, it is observed that very poor quality water samples are located in the eastern part and the poor water wells are located in the northwestern and eastern part while excellent water quality wells are located in the western and central part of the study area. The understanding of the groundwater quality can help the policymakers for the proper management of water resources in the study area.
