The presence of pathogens in drinking water may result from source water contamination
by human and animal activities, followed by improper or insufficient treatment. The
study was conducted to assess the bacteriological quality of water produced at the
Kwanyako Water Treatment Plant in the Central the Region of Ghana. Triplicate water
samples of Raw and Final water were collected in sterile 500ml polypropylene bottles,
and analysed for thermotolerant coliform (TTC) using the Most Probable Number (MPN)
method to determine the bacteriological quality of water before and after treatment. The
study was carried out for a period of 6 months (September, 2013 to February 2014). TTC
was positive for all Raw water samples but negative for all Final water samples. This
implied that, the water produced at the Treatment plant is efficiently treated and poses no
health threat.
