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...

Abstract Water sources for irrigation systems in the Red River Delta are crucial to socioeconomic growth of region's communities. Human activities (discharge) have polluted water source recent years, and from upstream is limited. Currently, surface quality index (WQI), which calculated numerous parameters (physical, chemical, microbiological, heavy metals, etc.) frequently used evaluate systems...

Abstract Water quality assessment using water index (WQI) is performed based on major variables reflecting the river characteristics. We evaluated of tributaries Nam River in South Korea. analyzed spatial characteristics cluster analyses and selected main (Cluster 1: chemical oxygen demand [COD], total organic carbon [TOC], nitrogen, phosphorus; Cluster 2: temperature [WT], dissolved [DO], COD,...

In the face of ongoing anthropogenic climate change, river water quality assessment has become increasingly important for maintaining ecological balance and supporting local downstream livelihoods. This research aims to create a new index (WQI) assess in Andean highlands (>2000 m.a.s.l.) change adaptation mitigation. We examined physicochemical bacteriological parameters benthic macroinverte...

Abstract Accurate assessment of the type and extent water pollution is a difficult complicated task. Therefore, use Water Quality Index (WQI) proves to be useful tool, as this index has advantage resulting in single number that easy communicate understand. One statistical methods can used develop new WQI equation for given body Multiple Linear Regression (MLR). work aims Mirim Lagoon through ML...

Ostracods are small crustaceans found in aquatic habitats and the present paper deals with the role of water quality index on their population diversity and seasonal fluctuations in the four lakes of Mysore city The present investigation was carried out from July 2004 to June 2005. The study revealed highest water quality index and population density of ostracods during summer and least during ...

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...

Given the complexity of water quality data sets, resources pose a significant problem for global public order in terms protection and management. In this study, surface drinking irrigation purposes was evaluated by calculating Water Quality Index (WQI) Irrigation (IWQI) based on nine hydrochemical parameters. The discriminant analysis (DA) method used to identify variables that are most respons...

This study was carried out on Rosetta branch water and 3 drains (El-Rahawy, El-Soble El-Gezira) that discharging wastewater into it, to assess the Water Quality Index (WQI) of their waters. investigation performed during period starting from winter 2017 summer 2018. The mean annual averages WQI values were good poor for irrigation (up 55) very aquatic life 97) at stations exposed discharged bra...
