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...

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...

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...
