Tap water contamination status of an intermittent water supply_.xlsx

The uploaded data are the values obtained from the tap water and reservoir water analysis from the Kathmandu valley. The data includes hydrogen (H) and oxygen (O) stable isotopic compositions analyzed using cavity ring-down spectroscopy (L1102-i, Picarro, Santa Clara, CA, USA). The abbreviation is used as δD and δ18O-H2O relative to Vienna Standard Mean Ocean Water (V-SMOW).Additionally for the nitrate concentration in the tap water was analyzed in understanding the tap water condition in the Kathmandu valley and was measured using ion chromatography (ICS-1100, Dionex, USA), with an analytical error of 5%.
