“…Firstly, special weights (w i ) in a scale of 1 (slightest consequence on water quality) to 5 (highest outcome on water quality) was allocated to every elemental parameter, on the basis of their supposed impact on primary health and their relative magnitude in the quality of drinking water (Sener & Davraz, 2013). The parameters having serious health impact and whose occurrence above the critical concentration amount could result in confined usage of the resource for household and drinking purposes were given the highest weight five (Varol & Davraz, 2014).…”

This study is aimed to assess the groundwater excellence within the rural areas of Sant Ravidas Nagar (Bhadohi), Uttar Pradesh, India. In the current work, estimation of groundwater excellence indices has been done to recognize the water quality for the appropriateness of groundwater resource for drinking and agricultural use. Twenty groundwater samples were collected and investigated for diverse geochemical parameters viz, pH, total dissolved solids (TDS), total hardness, cations and anions. The groundwater of the study region is neutral to slightly alkaline in nature. Piper's diagram classification shows that majority of the samples belong to CaMgHCO 3 hydrochemical facies. Gibbs plot specifies that majority of samples falls in rock dominance. The water quality index shows that the entire sample is under excellent water category. On the basis of TDS, all the samples are within the range of desirable to permissible for drinking and agriculture purpose. Forty percent samples of the study region are having nitrate content more than permissible limit (>50 mg/l) which is not fine for individual use. Poor drainage, domestic waste and use of N fertilization on farming land may be the main sources of nitrate in groundwater of the study region. On the basis of different water quality indices, groundwater of the study region is fit for agricultural use.

ABSTRACT:Tabriz is the largest industrial city in North West of Iran and it is developing rapidly. A large proportion of water requirements for this city are supplied from dams. In this research, groundwater quality assessed through sampling 70 wells in Tabriz and its rural areas. The purposes of this study are: (1) specifying spatial distribution of groundwater quality parameters such as Chloride, Electrical Conductivity (EC), pH, hardness and sulphate (2) mapping groundwater quality for drinking purpose by employing Analytic Hierarchy Process (AHP) method in the study area using GIS and Geosatistics. We utilized an interpolation technique of ordinary kriging for generating thematic map of each parameter. The final map indicates that the groundwater quality esaeicni from North to South and from West to East of the study area. The areas located in Center, South and South West of the study area have the optimum quality for drinking purposes which are the best locations to drill wells for supplying water demands of Tabriz city. In critical conditions, the groundwater quality map as a result of this research can be taken into account by East Azerbaijan Regional Water Company as decision support system to drill new wells or selecting existing wells to supply drinking water to Tabriz city.
