Abstract
Access to clean water is a basic human right and its essential for the survival of living organisms. Water also serves as a vehicle for the transportation of microorganisms, including human-associated bacteria. The study aimed to detect the presence of coliform bacteria in ten drinking water samples obtained from tap and manual water hand pumps. the results revealed that all tap water samples, tested negative for coliform detection, except for one sample which is utility water 4. In contrast, all samples from manual hand pumps tested positive for coliform, except for one sample which is ground water 3. Further analysis indicated that four out of the five samples that are tested to be positive for coliform contained the indicator organism, Escherichia coli, while ground water 2 did not. Antimicrobial susceptibility testing of the E.coli isolates showed that all were resistant to at least one antimicrobial, except for the isolate from ground water 1, which exhibited multidrug resistance to five antimicrobials. These findings provide valuable data for assessing and addressing water potability issues associated with manual hand pumps, and emphasize the importance of continuous monitoring of tap water quality. All of the water from the sampling sites tested are potable, except for the locations where the presence of coliform was detected.
