Abstract Valuation of water quality index (WQI) is one of the simplest, easily understandable, and efficacious techniques to evaluate the quality and suitability of water for drinking as well as other purposes. This research was aimed to investigate the drinking water quality of tube wells from different areas in Khulna City, Bangladesh, by developing the WQI. Water samples from 59 tube wells were collected from different locations during the pre-monsoon time. pH, electric conductivity (EC), dissolve oxygen (DO), total dissolved solid (TDS), chloride (Cl−), nitrate (NO3−), and total hardness of the collected water samples were analyzed for the calculation of WQI. The mean value for pH, EC, DO, TDS, Cl−1, NO3−, and total hardness was 7.30, 1650 μS/cm, 1.60 mg/l, 1188.7 mg/l, 414.6 mg/l, 0.029 mg/l, and 52.03 mg/l, respectively. The calculated WQI values for individual places were distributed spatially through mapping by using ArcGIS software. Based on the WQI values, the drinking water was categorized into excellent, good, poor, very poor, and unfit for drinking purposes. The calculated WQI values ranged from 40.11 to 454.37 with an average value of 108.94. Among all the groundwater samples, 11.86% were excellent, 54.24% were good, 23.73% were poor, 1.69% were very poor, and 8.47% were unfit for drinking purpose based on WQI. The results showed that the groundwater quality of most of the studied areas of Khulna city could be considered safe and suitable for drinking barring the elevated EC and chloride content in some areas. Since Khulna city is situated in the southwestern part of Bangladesh and gradually approaches toward the base level of the Bay of Bengal which might be the source of salt concentration in the groundwater of Khulna city, Bangladesh.

In the present paper, geochemical characteristics of groundwater have been studied using Water Quality Index (WQI) and Piper trilinear diagram. The water quality index offers a quantitative representation of overall quality of water for any intended use and helps in pollution abatement programmes and management. Whereas, the Piper diagram shows graphical representation of the hydrochemical facies of a set of water samples. In the present work, twenty-five groundwater samples were collected from various locations in the Bijnor district. The samples were investigated for pH, electrical conductivity, total dissolved solids, carbonate, bicarbonate, chloride, sulphate, nitrate, nitrite, phosphate, calcium, magnesium, sodium, potassium, total hardness, fluoride and trace metals. The Piper trilinear diagram showed ++ - that groundwater of the district is Ca-Mg-HCO type. Ca and HCO were found dominant ions among cations and 3 3 anions, respectively. The WQI was found in the range of 71 to 86, which indicated that the samples fall under the fair to good category. Bureau of Indian Standards (BIS) checks were also applied to examine the water quality for the drinking purpose. The results revealed that most of the water quality parameters are within the permissible limits except iron and manganese. Based on the results, groundwater of the Bijnor district needs treatment for drinking purpose for the locations where the WQI is found below 75.

The present work is aimed at assessing the water quality index (WQI) for the Rajghat reservoir water on Bewas River life line of Sagar city. This has been determined by collecting water samples from selected 5 locations covered entire reservoir, and subjecting the samples to a most important physico-chemical analysis. 14 parameters have been considered: DO, water temperature, Conductivity, TDS, TSS, pH, Total hardness, calcium content, magnesium content, Total alkalinity, chloride, nitrate, o-Phosphate, and iron present in water samples. The results obtained reveal that the water quality of the area needs some degree of treatment before consumption. It therefore becomes imperative to regularly monitoring the quality of water to protect it. The objective of the present work is to compute water quality index values to assess the suitability of water for human consumption. Water level has a net positive effect on water quality in water body through dilution of environmental parameters. Consequently, local management agencies should pay more attention to nutrient concentrations during the monitoring schedule, as well as during the low-water periods which manifest a relatively bad water quality state.

Studying groundwater quality in arid and semi-arid regions is essential significant because it is used as a foremost alternative source for various purposes (human and animal consumption, economic, agriculture and irrigation). Geographic Information System and Water Quality Index techniques were utilized for visualizing and evaluating the variations of groundwater quality in the studied area. Total twelve wells were sampled and twelve groundwater quality (chemical) parameters; pH, Total Alkalinity, Total Hardness (TH), Total Dissolved Solid (TDS), Electrical Conductivity (Ec), Potassium (K), Nitrate (NO3), Sulfate (SO4), Chloride (Cl), Calcium (Ca), Magnesium (Mg) and Sodium (Na) were analyzed in the laboratory. Inverse Distance Weighted technique was used as a useful tool to create and anticipate spatial variation maps of the chemical parameters. Predicting or anticipating other areas not measured, identifying them and making use of them in the future without examining samples. The results of this research showed that 8.3% of the studied wells have excellent groundwater quality, and almost sampling wells about 75% found in good groundwater quality, while findings of groundwater quality of 16.7% studied wells belong to poor water quality due to standards of Water Quality Index. Moreover, spatial analysis in term of groundwater quality map showed that Excellent groundwater quality was detected in well 3, very good groundwater potential was noticed in six studied wells (wells 2, 6, 8, 10, 11 and 12), and other sampling wells (wells 4 and 7) were observed as good groundwater quality, while poor water quality was observed in wells (well 1 and 5). Hence, spatial distribution maps showed that the almost groundwater quality in the area about 1046.82 km² (99.04%) are suitable for drinking purpose, whereas proximate 10.18 km² (0.96%) are observed as poor water quality and inappropriate for consumptions especially in the southern part of the area.
