Fecal coliform bacteria only isolated from well
water sample of Tehkal Bala. Simalary all tube well’s
water samples were analyzed for detection of E. coli.
Present study result indicate that all tube well’s water
sample were found free from E. coli contamination.
In analyzed distribution network samples coliform
Numbe
rs range from 1.1 to >23 MPN/100 mL. highest
coliform count >23 MPN/100 mL were found in
distribution network samples of Shaheen Town, Tehkal
Bala, New Arbab Colony , Ahmad Abad and Academic
Town, while lowest coliform count 1.1 MPN/100 mL
was found in distribution network sample collected
from Hayatabad Phase 4. All distribution network
samples were coliform positive. Fecal coliform were
isolated from water distribution network of Tehkal
Bala, New Arbab Colony, Academic Town, Sadar Mall

were further analyzed for detection of E. coli. E. coli
was detected in water distribution network samples of
Tehkal Bala, New Arbab Colony and Academic Town.
Water samples collected from storage tanks coli
form bacteria count within the range between 2.2 to >23

were detected in storage tank water sample collected
from Hayatabad Phase 4 while maximum coli form
bacteria were detected in storage tanks water sample of
