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.

Drinking Purpose

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.

Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Therefore, the aim of this study was to evaluate the quality of groundwater in Ardakan for drinking purpose using WQI. Spatial analysis was conducted with the geographic information system (GIS). Materials and Methods: This is a descriptive, cross-sectional study to investigate the quality of groundwater in Ardakan for drinking purpose. Information on total dissolved solids (TDS), total hardness, pH, electrical conductivity (EC), bicarbonate (HCO3-), chlorine (CL-), sulfate (SO42-), nitrate (NO3-), calcium (Ca2+) and magnesium (Mg2+) of 24 wells was obtained from Ardakan Health Center. The characteristics of the stations were determined using the Global Positioning System (GPS) and transmitted to the map prepared in the GIS environment. The calculated values of the WQI were zoned in the GIS environment by Inverse Distance Weighted (IDW) method. Results: Based on the WQI, well no.5 has the best quality water (17.61), which has the lowest WQI, and the highest value of WQI was obtained for well no. 20 (156.86). Conclusion: The results of the study showed that none of wells have drinkable water, 13 wells had good quality water, and 11 wells had poor quality and should be treated for drinking.

Groundwater as a source of potable water is becoming more important in Nigeria. Therefore, the need to ascertain the continuing potability of the sources cannot be over emphasised. This study is aimed at assessing the quality of selected groundwater samples from Ilorin metropolis, Nigeria, using the water quality index (WQI) method. Twenty two water samples were collected, 10 samples from boreholes and 12 samples from hand dug wells. All these were analysed for their physico – chemical properties. The parameters used for calculating the water quality index include the following: pH, total hardness, total dissolved solid, calcium, fluoride, iron, potassium, sulphate, nitrate and carbonate. The water quality index for the twenty two samples ranged from 0.66 to 756.02 with an average of 80.77. Two of the samples exceeded 100, which is the upper limit for safe drinking water. The high values of WQI from the sampling locations are observed to be due to higher values of iron and fluoride. This study reveals that the investigated groundwaters are mostly potable and can be consumed without treatment. Nonetheless, the sources identified to be unsafe should be treated before consumption.KEYWORDS: groundwater, water quality index, potability, physico - chemical, parameter

A water quality index (WQI) is a tool which numerically summarizes the information from multiple water quality parameters into a single value and this information can be used to assess spatial and temporal variations in overall water quality. However, these indices are time and region specific and may be influenced by local factors. In the present study, water quality index has been worked out to assess the spatial and temporal variation of groundwater quality status for future planning and management of North Goa. Data of 19 groundwater samples were collected in the year 2005 during January, March and April, are used for the analysis. The Water Quality Index has been computed using four parameters viz. pH, Total Dissolved Solids, Total Hardness and Chloride. The WQI results show that the overall water quality class is ‘good’ and water is acceptable for domestic use.
