Effects of Deforestation and Nutrients Loss on Watershed Degradation in Hana Urak and Karkhasa Regions

5 Abstract: This study was carried out to assess the water quality of Hana Urak and Hazar Ganji (Karkhasa) of Quetta city. A total of 12 water samples were collected from two locations. The physico-chemical parameters for water quality included pH (7.56±0.2-7.43±0.19), total solids (0.03±0.007-0.04±0.01) and total coliform bacteria (412.33±52.08-381±98.38). Some heavy metals (Cu, Mn, Fe, Pb) were also determined. All parameters were compared with standard permissible limits to assess the best-designated use of water for drinking purposes. The concentration of all the trace metals was with in the permissible limits for its use as drinking water and other purposes according to World Health Organization (WHO). Since the water of both areas contain high number of coliform bacteria, hence cannot be used for drinking purposes without prior treatment. The present study recommends that top priority should be given to monitor the depletion of water level of both areas.
