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...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

A study of the quality drinking water sources - surface waters river systems city Latacunga and canton Pedro Vicente Maldonado, Ecuador, was carried out during 2018 2019. The general sanitary index (WQI) calculated according to Russian methods, National Sanitation Foundation (NSF-WQI) Ecuadorian regulation. Results from parameterizing quality, obtained by WQI NSF-WQI methods combined into an ov...

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...

Water quality indices (WQIs) are efficient and powerful tools for evaluating, organising and communicating information on the overall quality of surface water bodies. The use of these indices may be very helpful in evaluating the water quality of aquatic systems in relation to the EU Water Framework Directive (WFD). In this study, two well-known water quality indices have been selected for eval...

In this work, the possibility of using four water quality indices (WQIs) to evaluate status small rivers in Mediterranean region (Northern Greece) was investigated. The WQIs selected were NSF WQI, Oregon CCME WQI and Prati’s Index Pollution applied three rivers, namely Laspias, Kosynthos Lissos, located prefectures Xanthi Rhodope, Northern Greece. individual calculated based on values 11 physic...

A Water Quality Index (WQI) is a useful statistical tool for simplifying, reporting and interpreting complex information obtained from any body of water. A simple number given by any WQI model explains the level of water contamination. The objective was to develop a WQI for the water of the Luis L. Leon dam located in the state of Chihuahua, Mexico. Monthly water samples were obtained in 2009; ...
