Most
probable number (MPN) test was done to detect the coliform
in water samples collected from mobile vendors, protected
well and municipal tap water supplied from Jeedimetla
municipality. The study revealed that the number of
coliforms was very high (≥ 1500) in water samples collected
from mobile vendors. The bacteria were identified as
Escherichia coli, Pseudomonas aeruginosa and
Staphylococcus aureus. Bacteriological examination of
water samples collected from different sources showed that
the water of mobile vendors and ground water of jeedimetla
area was not potable while the municipal tap water was found
to be safe for drinking.
