TL;DR: In this article, the suitability of water of forty-four fixed bore wells of Kanchipuram district, Tamil Nadu, India was assessed for 9-year period.
Abstract: The grade of irrigation water available to irrigators has a significant impact on crops as well as yields. Therefore, it is a need to better understand irrigation water quality. The present study mainly focuses on the assessment of the suitability of water of forty-four fixed bore wells of Kanchipuram district, Tamil Nadu, India. The groundwater sample datasets of post-monsoon (2005–2013) and pre-monsoon (2006–2013) season were collected for 9 years. Water quality indices, namely sodium adsorption ratio, exchangeable sodium percent (SSP or %Na), residual sodium carbonate (RSC or RA), Kelly’s ratio, permeability index, chloroalkaline indices (CAI1 and CAI2), potential salinity (PS), magnesium hazard, total dissolved solids and total hardness, have been calculated for separate bore wells. The r1 and r2 indices show that groundwater of the study area is Na+–SO42− and deep meteoric percolation type. Majority of the wells are fall under moderate to unsuitable category of water for irrigation purposes. Further, wells water has also been classified on the base of meteoric genesis index.

TL;DR: In this article, the groundwater quality for drinking purposes was assessed using statistical index of Akola and Buldhana districts, Maharashtra, India using WQI maps generated using ArcGIS 10.3 software.
Abstract: The groundwater quality for drinking purposes was assessed using statistical index of Akola and Buldhana districts, Maharashtra, India. The sampling was performed in both the seasons (pre-monsoon and post-monsoon), a total of nine water quality parameters (pH, TDS, Ca, Mg, Na, K, Cl, HCO3 and SO4) were estimated. Water quality index (WQI) method was used to classify groundwater on the basis of score, and WQI maps were generated using ArcGIS 10.3 software. These thematic maps of WQI have given detailed information of groundwater suitable areas for drinking purposes during pre-monsoon and post-monsoon. Majority of water samples falls in the category of suitable zones for drinking purposes. The aqueous geochemical modeling has been given statistics of mineral exposed during pre-monsoon and post-monsoon of the Mahesh river basin area. Geochemical model WATEQ4F has been used to compute the saturation index of different minerals of the study area. The saturation index of the carbonates helps us to know the thermodynamic stability of groundwater and to discover out the geochemical movements of groundwater.

TL;DR: In this paper, the suitability of groundwater for drinking and irrigational purposes of two distinctly located geographical areas, Koprivnica-Križevci County, Croatia and district Allahabad, India, was discussed.
Abstract: The hydrochemical study was conducted to outline the suitability of groundwater for drinking and irrigational purposes of two distinctly located geographical areas, Koprivnica-Križevci County, Croatia and district Allahabad, India. A total 160 groundwater samples were collected from sources (in hot and cold seasons) of both countries during 2 years (2011–2012) to evaluate the recent hydrochemical status of groundwater. Samples were analyzed for 12 various physico-chemical parameters.The Koprivnica-Križevci County has Ca–HCO3 water type, whereas in Allahabad it prevails as Mg–HCO3. All the parameters were below the maximum acceptable value (MAV) of standards (WHO, US EPA, Indian and Croatian Standards). The usage and consumption of groundwater should be of no concern with regard to inorganic pollutants. Irrigational indices (residual sodium carbonate content, magnesium hazard, permeability index, exchangeable sodium percentage, and salinity hazard) showed that groundwater is suitable for irrigational purposes. Hierarchical clustering analysis (HCA) has resulted into four groups due to the processes on natural and anthropogenic factors. The principal component analysis (PCA) has shown that first factor (all physico-chemical analyzed variables) explains 27.75% of the total variability and another factor (geographical distribution) accounts only for 10.46%. We found that local environmental conditions are more important predictor than geographical distribution. The present study may be helpful in dealing for further studies concerning groundwater quality issues in the distinctly located geographical areas. The groundwater quality is essential for management and sustainability of water resources, economic development, and human health.

TL;DR: In this paper, the primary objective was appraisal of groundwater quality during pre- and post-monsoon seasons for irrigation purposes, and the results highlight that the study area has a high salinity content (C3) and low sodium (S1) and the maps for different water quality parameters were generated using inverse distance weighted (IDW) interpolation method in ArcGIS 10.3 software.
Abstract:
The primary objective was appraisal of groundwater quality during pre- and post-monsoon seasons for irrigation purposes. Good quality groundwater is required for high crop yields in arid regions. A total of 45 samples were collected from wells and analyzed in the laboratory for this research work. Different water quality parameters were determined from these samples, namely electrical conductivity (EC), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), sodium percent (Na%), and permeability index (PI) during the pre- and post-monsoon season. The water types were identified through a Piper-trilinear diagram. Fifty per cent of the water samples of the total basin area fall under the saline category. The local farmers heavily rely on groundwater for the irrigation of crops. Excess use of groundwater for irrigation raises soil salinity. Some parts of the study area are facing serious problems such as loss of crop yields, and low availability of good quality groundwater even for drinking purposes. The results highlight that the study area has a high salinity content (C3) and low sodium (S1). The maps for different water quality parameters were generated using inverse distance weighted (IDW) interpolation method in ArcGIS 10.3 software.
