Abstract The Water Quality Index (WQI) is a single, deferential metric for describing the state of water quality as whole, which aids in selection effective remediation strategies. Fifteen surface samples were taken from Euphrates AlHaydria neighborhood AL-Najaf (Iraq). Various physicochemical parameters, including pH, total dissolved solids (TDS), calcium, chloride, sulfate, and electrical con...

the aim of this study was to assess the potential impact of trout farm effluents on water quality of zaringol stream based on nsfwqi and wqi indexes. some physicochemical water quality parameters were measured from 14 point during december 2009 to september 2010 seasonality. the average value of nsfwqi is 53.21 and it shows spatial and temporal variation. the maximum value or best water quality...

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...

River Ganga is one of the prime sacred National Rivers of India, closely associated with economic, social, and cultural heritage of Indian people. Recently, it has been subjected to immense degradation and pollution as a result of receiving huge amounts of domestic and industrial wastewater as well as religious ritual activities and surface runoff. The present study attempts to study spatial an...

The Choghakhor International Wetland plays an important role in preserving and protection of part of the plant and animal species in the Iranian plateau. Since the water of this wetland is utilized for different human purposes, complete periodic chemical and physical quality assessment of its water seems necessary. Water quality index (WQI) was calculated using the following eleven parameters: ...

Water quality index (WQI) is a valuable arithmetic tool that depicts the overall status of water in single number to prioritize for management interventions. This study aims assess based on WQI provide insights into aquatic ecosystems Marshyangdi River basin, tributary Narayani River, originating from Himalaya. samples were collected twenty-one sampling locations covering four districts upstrea...

This present hydrological study assessed the groundwater quality of Biratnagar Metropolitan by application Water Quality Index (WQI). It has been determined on basis analyzed samples for some important physicochemical parameters such as pH, turbidity, electrical conductivity (EC), dissolved oxygen (DO), free carbon-dioxide (FCO2), bicarbonate (HCO3), total hardness (TH), phosphate (PO4-P), nitr...
