Water samples are collected weekly during the period from February 2015 to April 2015 from ten sites.

Results show that the chlorides, total dissolved solid and electrical conductivity less than acceptable limit of standards, but total hardness and heavy metals in some samples higher than acceptable limit of standards while the other parameter is good.WQI shows that results is excellent and good for drinking for all location and months except site (2) gave higher value (65.184) in March and site (9) gave high value (57.78, 57.23) at March and April indicate that sites is poor for drinking water.
