Hydrogeochemical Assessment of Water Resources of Bringi Watershed, Kashmir Himalayas, India; Implication on Drinking and Irrigation Water Quality
Twenty four water samples from streams and karst springs of Bringi watershed, SE Kashmir were collected on bimonthly basis and analyzed for major ions to assess the water quality for drinking, domestic and agricultural purposes. The Hydrogeochemical assessment revealed that the carbonate weathering as the dominant source of major ions in water samples. The quality assessment was made through the estimation of pH, electrical conductivity (EC), total dissolved solids (TDS), Ca2+, Mg2+, Na+, K+, Cl-, HCO3 - and SO4 2-. The water samples are suitable for drinking purposes as per WHO and ISI standards. Parameters like magnesium content (MC), percent sodium (PS), total hardness (TH), sodium adsorption ratio (SAR), salinity hazard (SH), potential salinity (PS), salinity index (SI), permeability index (PI) and residual sodium carbonate (RSC) were calculated. Study of all these parameters indicates that the stream and spring water samples are suitable for irrigation purposes.
