conclusions according to the average of wqi index, quality of water was good in station number one, medium in station number two, and bad in the rest of stations. according to the wilcox index, qualities of water in third station were medium and in the rest were good. results by using wqi, the best water quality was reported in station number one with the scalar quantity of 71.11 (water with be...

The present study was mainly proposed to investigate the quality of groundwater for drinking in Kifri District. main aim this identify some pollutants using two types indexes which are: Nemerow’s pollution index (NPI) and Water (WQI). samples were collected from 36 stations (deep wells) analyzed seven physico-chemical parameters including EC, TDS, pH, TH, TA, Ca+2 andSO4-2; as well as, results ...

The present work aims to assess the water quality index (WQI) of Manyad Storage tank, Aurangabad district, Maharashtra, India. surface sample were assessed for physico-chemical parameters namely pH, Electrical Conductivity, Total Dissolved Solid, Hardness, Bicarbonate, Chlorides, Sulphates, Nitrates, Calcium, Magnesium, Sodium, Potassium and Fluoride in post-monsoon season 2020. For calculating...

Various human activities have been the main causes of surface water pollution. The uneven distribution industrial enterprises in territories river basins Ukraine do not always allow real state quality to be assessed. This article has three purposes: (1) modification Ukrainian method for assessing WQI, taking into account level negative impact most dangerous chemical elements, (2) modeling WQI a...

Water quality indices (WQIs) are practical and versatile instruments for assessing, organizing, disseminating information about the overall status of surface water bodies. The use these may be beneficial in evaluating aquatic system quality. CCME (Canadian Council Ministers Environment) NSF (National Science Foundation) WQIs were used assessment (depth = 1 m) Lake Union, Washington State. These...

Economic expansion coupled with population growth and associated anthropogenic activities are a threat to water resources globally. This study assessed the dynamics in quality trophic status of one South Africa's hyper-eutrophic reservoirs, Hartbeespoort Dam. Spatio-temporal variability parameters was determined on historical data spanning period forty years (1980-2020), aim determining decadal...

there are several factors influencing the water quality based on its usage. the quality of drinking water is of the vital concern for human health and life. an essential attempt has to be done to develop a water quality index (wqi) corresponding with different conditions and characteristics of the relevant river or water body such as geographical, hydrological, discharge rate and pollution sou...

Aims of the Study: The physical, chemical and biological characteristics of Karaj River (near the city of Tehran, Iran), has been studied to evaluate the suitability of its water for domestic uses. Materials & Methods: Samples of water were collected from various localities before, in and after Karaj Dam Lake and were analyzed based on needs for Water Q...
