—The aim of this study was to investigate the
microbial quality of drinking water distributed through water
dispenser machines located in schools and universities in
Ajman, UAE. In total, 49 drinking water samples were collected
from water dispenser machines in the schools and university's
premises in the emirate of Ajman. Total coliform and E.coli
were detected using Colilert test. P. aeruginosa colonies were
counted on Pseudomonas agar using the membrane filtration
method. Overall, 25 out of total 49 samples were found to
contain either P. aeruginosa, or total coliform or both. Six
samples were found positive for total coliform group members,
whereas nineteen of the samples were positive for P. aeruginosa.
Ten water samples were found positive for both total coliform
and P.aeruginosa. P.aeruginosa colonies count ranged between
4 to 51 colonies per 250 ml of water sample. In conclusion,
overall microbiological quality of 25 drinking water samples
distributed through the water dispenser machine was found
unsatisfactory, and this could be attributed to the poor
maintenance and improper hygienic conditions of water
dispenser machines. In order to safeguard public health, more
efforts such as community awareness program, strict
regulations such as regular inspections by the local
municipalities are needed.
