Advance statistical technique as heavy metal pollution index (HPI) was used for assessment of suitabilityof 17 ground water sources of district Haridwar for drinking purpose. Water samples were analyzedfor Cu, Mn, Pb, Zn, Cr and Fe as water quality parameters using atomic absorption spectroscopy(AAS) as per BIS and APHA standards. Results showed that the concentration of all the analyzedheavy metals were found in all the selected ground drinking water sources below their standard limitduring the study, except one i.e. only lead was found (0.011 mg/L) more than its standard limit (0.01mg/L) at H13 during PRM 2014. Suitability of studied drinking water sources have also been evaluatedon the rating scale along with determination of seasonal and spatial variations. Results may attributethat HPI of the water sources were generally below its critical limit and studied water sources weresafe for human consumption with respect to analyzed heavy metals. The results of the present researchwork provide significant information for water resources management, which helps to better meet thefuture challenges.
