Safe drinking water is a basic requirement for good health. Fresh already limited resource in many parts of the world. In next century, it will become even more due to population growth, urbanization and climate change. Purpose. Provide comprehensive assessment quality Kaniv Reservoir based on calculation Water Quality Index (WQI). Methods. Analytical-synthetic method, geo-information (cartogra...

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...

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...

For more than 25 years, the Department of Environment (DOE) Malaysia has implemented a water quality index (WQI) that uses six key parameters: dissolved oxygen (DO), biochemical demand (BOD), chemical (COD), pH, ammoniacal nitrogen (AN), and suspended solids (SS). Water analysis is an essential component resources management must be properly managed to prevent ecological damage from pollution e...

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...

Abstract The prime objective of this study is to develop a water quality index (WQI) identify the relationship between drinking and prevalence Chronic Kidney Disease Uncertain Etiology (CKDu) in Uva Province (UP). For this, all CKDu patients province were recorded. 251 groundwater samples collected analyzed for their major cations anions. Following procedure, spatial distribution maps patients,...
