Abstract
The study comprises physico-chemical and bacteriological analysis of tap water quality supplied to Shah
Faisal town, a densely populated town of Karachi. Twenty six samples were collected from different sites.
The assessed physico-chemical parameters (pH, Turbidity, TSS, TDS, chlorides, hardness, calcium,
magnesium, sodium and potassium) were found within acceptable limits set by WHO and NSDWQ
guidelines for drinking water whereas, sulphate concentration slightly exceeded from the limits. Chlorine was
found in 5 stations only. The problem is provoked by poor sanitation and water supply conditions. Twentytwo water samples failed to meet the water quality criteria set by NSDWQ and WHO and were found to be
extremely faecally contaminated and posed serious health problems. Effective measures are urgently required
for water quality management in the city.
