However, contents of Pb and Zn were above BIS limits in all the regions. The concentration (mg/l) of Mg, NO3-, Cl- and As was in the ranges of 14.25- 30.61, 5.10- 9.88, 16.42- 74.96 , 0.001- 0.014 respectively, which were below prescribed standards. Cd was detected (0.001 mg/l) in Solan region only, however it was within BIS limits. Water Quality Index (WQI) computed by using nine parameters varied from 78.58- 219.78 (very poor to unsafe drinking water class). Interestingly, water sources of all the high disease burden regions were unsafe for drinking (WQI: 102.02- 167.04). Water quality deteriorated more in the monsoons. The study therefore warrants remedial actions of water resource protection and conservation for provision of potable water. ER -
