Water Quality Evaluation of Chapurson Valley in Hunza Nagar, Gilgit Baltistan, Pakistan, Based on Statistical Analysis and Water Quality Index

Water borne ailments are of serious public health concern in Gilgit Baltistan’s (GB) region Pakistan. The pollution load on the glacio-fluvial streams and surface water resources Chapurson Valley Hunza Nagar area GB is increasing as a result anthropogenic activities tourism. present study focuses quality drinking valley. addressed fundamental criteria order to understand state To ascertain current status physico-chemical, metals, bacteriological parameters, 25 samples were collected through deterministic sampling strategy examined accordingly. physico-chemical parameters from valley found meet World Health Organization (WHO) guidelines water. showed pattern mean metal concentrations Arsenic (As) > Lead (Pb) Iron (Fe) Zinc (Zn) Copper (Cu) Magnesium (Mg) Calcium (Ca). As, Cu, Zn, Ca Mg concentration under WHO range. However, results that Pb Fe at much higher than recommended guidelines. Similarly, analysis indicate heavily contaminated with organisms importance (including total coliforms (TCC), faecal (TFC) fecal streptococci (TFS) more 3 MPN/100mL). Three principal components, accounting for 48.44% variance, revealed using component (PCA). Bacteriological shown be main determinants depicted by PCA analysis. dendrogram Cluster Ward’s method validated same traits locations during geospatial Inverse Distance Weight (IDW) method. Based these findings, it most likely those essentially tourism upstream channels. Metals may released into groundwater few underlying sources weathering erosion. This suggests susceptible contamination such no treatment facilities or protective measure have been taken encounter load. People without questioning about quality. It should monitored standard protocol so protect not only but safe guard sustainable
