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...

Globally, water quality indices (WQIs) are beneficial for evaluating groundwater and surface quality. The Canadian Council of Ministers Environment Water Quality Index (CCME WQI) was combined with the parametric values given by Directive 98/83/EC to investigate possible suitability resources human consumption on Rhodes Island. Chloride (Cl?), pH, calcium (Ca2+), electrical conductivity (CND), c...

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...
