The study to calculate the water quality index was conducted in Gulf of Tonkin at surface August 2018. calculation results showed that out 48 surveyed points, there 1 point Northeast area poor quality, 15 points and coastal areas from Thanh Hoa Thua Thien Hue medium 14 Tonkin, Con Co Island good remaining 18 Bach Long Vi excellent quality. Overall, average whole region (average WQI = 79). Consi...

The spatial assessments of water supply quality from wells, springs, and surface bodies were performed during the dry rainy seasons in six municipalities eastern regions Michoacán (Central Mexico). Different physicochemical parameters used to determine supplies’ Water Quality Index (WQI); all communities presented good quality. analysis indicates that many within limits set by international sta...

BACKGROUND Public health is at risk due to chemical contaminants in drinking water which may have immediate health consequences. Drinking water sources are susceptible to pollutants depending on geological conditions and agricultural, industrial, and other man-made activities. Ensuring the safety of drinking water is, therefore, a growing problem. To assess drinking water quality, we measured m...

The operationalization of water resource protection initiatives for surface quality and equitable allocation is critical sustainable socio-economic development. This paper assessed Blesbokspruit River Catchment’s status, using the South African Water Quality standards Index (WQI). Protection levels quality, waste discharge point sources were set evaluated total maximum daily loads (TMDLs) chemi...

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...

Soil use and occupation alter the physicochemical biological processes of aquatic ecosystems. Urban streams are fundamental components macro-drainage system cities; however, with advance urbanization, most modified to point that they no longer recognized as but sewage receptors. Physical diagnosis monitoring water quality essential understand trophic state these ecosystems in relation environme...

Groundwater is a vital resource for the drinking water supply to people in areas residing coastal zones. Rapid industrialization increased human population, and anthropogenic activities led groundwater pollution. The quality should be continuously monitored analyse suitability of water, it only possible by index. In current study, we attempted determine Mandal headquarters zones Srikakulam dist...

The present study aims to have a comparative study of the results, from biological monitoring as well as conventional method, based on physico-chemical variables. Water quality index (WQI) and planktonic diatom metrics have been used to determine water quality and ecological conditions of the Dong Nai River (DNR) and Canonical Correspondence Analysis (CCA) to find out the main environmental var...

Abstract The aim of this paper is to present the potential using neural network modelling for prediction surface water quality index (WQI). An artificial has been performed physicochemical parameters (TDS, chloride, TH, nitrate, and manganese) as an input layer model, WQI output layer. have taken from five measuring stations river Warta in years 2014-2018 via Chief Inspectorate Environmental Pr...
