Abstract

Clean drinking water is the basic needs of human-beings. Contamination in drinking water is the most prominent issue in the rural and urban areas of the developing countries. Rate of causalities is increasing because of water borne diseases which is due to rapid rise in urbanization which sequentially leads to elevation of water pollution level. World Health Organization (WHO) bears that almost three billion people are the effectives of unsafe water. Developing countries like Pakistan have a growing urbanization rate 31 to 34% whereas accessibility of safe drinking water has declined more than 40 percent. The present research was conducted to examine the water quality characteristics of Rawal Dam Reservoir, Islamabad, Pakistan. Water samples were randomly collected from streams and mid of the Dam. Standard methods were used to determine the physiological parameters. Chemical parameters were also assessed in the samples by using UV Visible Spectrophotometer and standard method. The results obtained were compared with Pak-EPA standard limit, the concentration of Physical and chemical parameters were above the permissible limits made by Pak-EPA in different streams as well as in Rawal dam.
