SURVEILLANCE OF
MICROBIAL INDICATORS AND PHYSICOCHEMICAL PARAMETERS TO INVESTIGATE
POLLUTION STATUS OF LAHORE CANAL
ARIFA TAHIR1*,
FARIHA KANWAL1 AND BUSHRA MATEEN2
Abstract: The Lahore
canal is an important watershed in Lahore. The present study was
conducted to monitor pollution load of Lahore canal. Surface water was
collected from the middle of the canal at four different sites, and analysed for physicochemical parameters (temperature, pH, EC, DO, BOD5,
turbidity, nitrates, phosphates) and microbial load (bacteria (TVC),
total coliform and fungi). Water quality parameters were monitored from
May to August at four sites along 17Km long patch. Surface water was
collected in the middle of the canal. The results were compared with IWQ
guidelines proposed by WWF, Pakistan. Pollution load of Lahore Canal
revealed an alarming situation. Water can be used for the irrigation
purpose, but only with advanced treatment.
