Abstract The Ciliwung River receives loads from various sources of pollution along the border, both agricultural waste, industrial and domestic waste. wastes that enter river cause a decrease in water quality. This study aims to determine quality status Jakarta segment based on Pollution Index (PI) Pesce-Wunderlin Water Quality (WQI). Monitoring was carried out February-September 2021 at 18 obs...

Groundwater pollution is considered a major concern in today’s world. Most industries Pakistan produce untreated wastewater, extracting from and contaminating nearby water source the soil. This study was conducted Nithar Ke area of Chiniot District to assess impact flow wastewater over on groundwater quality. It aimed to: (1) investigate conditions industrial wastewater; (2) spatial variability...

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,...

Abstract Clean and safe water is vital for human health, whether it used drinking purpose, food production or domestic use. The aims of study are to investigate raw quality parameters analysed Water Quality Index (WQI) at Timah Tasoh Dam. research also analyses the treated Treatment Plant, Kampung Belukar, Kechor Taman Bukit Kaya, then compared National Standard Drinking (NSDWQ) World Health Or...

The practice of river quality classification usually uses Water Quality Index (WQI) to evaluate the WQI values river. However, due huge data collection on pollution with uncertain water parameter values, need a different approach classify quality. One supervised algorithms known as K-Nearest Neighbors (KNN) seems give new for where each points are classified according k number or closest neighb...

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...

evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...
