Complex Linkage between Watershed Attributes and Surface Water Quality: Gaining Insight via Path Analysis

چکیده
Understanding the influence of various variables on surface water quality is extremely important for protecting ecosystem health. The principal aim this study to assess direct (DE), indirect (IE) and total effects (TE) socio-economic, terrestrial hydrological factors via path analysis through lens 15 sub-basins located Indus basin, Pakistan. Four models were selected based Comparative Fit Index (CFI) = 0.999 value. First model showed that rangelands having low population density decline river runoff which decreases instream Electrical Conductivity (EC) because lower anthropogenic activities. Second depicted croplands higher enhance due irrigation tail discharge EC dilution. Third with increases NO3 concentration unscientific application water. Fourth unveiled Gross Domestic Product (GDP) concentration. To protect health, Best Management Practices (BMPs), precision farming modern techniques should be adopted reduce discharges containing pollutants entry in River.

متن کاملChemical and microbiological analysis of surface and ground drinking water quality
Drinking water has received considerable attention recently. However, misuse and mismanagement have resulted in a rapid and widespread decline in source-water quality and supply. Water quality guidelines can be used to identify constituents of concern in water, to determine the levels to which the constituents of water must be treated for drinking purposes. Membrane technology for the water cyc...
