Abstract:
The project “DRINKING WATER QUALITY ANALYSIS OF RAWALPINDI
CITY” was carried out from April 2010 to July 2010 for recent monitoring of
drinking water supply system of selected areas of Rawalpindi, keeping in view the
recent National and International quality standards on the subject. Samples were
randomly collected from different RDA water filteration plants and tap water in
Westridge, Chaklala, D-block Satellite town, Kurri road and Pirwadhae area. A
standard method for sample collection was followed and, in each case, two
different plastic bottles were used for bacteriological, physical and chemical
parameters. These samples were then analyzed using reliable analytical procedures
available in ASTM and adopted by PCRWR. The analytical data has been
compiled. Results of all the parameters have been individually depicted in different
figures and have been discussed. Almost half of the samples were found to be
contaminated with respect to the coliform and fecal coliform bacteria, making it
unsuitable for drinking. However, detail studies should be conducted to know the
cause of bacteriological contamination. The results regarding the physical and
chemical parameters were found within the recommended National and
International guidelines for drinking water. It is further recommended to undertake
further studies over a wider area in order to elucidate the relationship between the
underground hydrology and parameters important with respect to the water quality.
