Water Quality Assessment of Fresh Water Resources in Gilgit Baltistan

Abstract

Water is essential for survival of all living organism present on earth. There is no life without water. Water may be polluted due to anthropological activities, industrial discharge and sewages which affect the physical and chemical properties of water. The safe water is essential for healthy living. The present study area was Gilgit Baltistan. Water samples were collected from the springs, lakes, rivers, tap water and underground water and analyzed for physio chemical parameters. Six different physio chemical parameters were analyzed by using different laboratory methods and procedure. In the present study the value of pH ranged from 5.93-8.09, electrical conductivity 186μS-1444.3μS, total alkalinity 0-1638ppm, Calcium 20-174.6ppm, total dissolved oxygen 7-13.2, total dissolved solid 51.1-461.6, turbidity 0.18-19.86, Magnesium 6.4- 64.4ppm, and Chloride 68.25-191.27. The results obtained were compared with WHO standards for drinking. Some parameters fall within WHO standard while some parameters were exceeding or below permissible limits.
