| dc.description.abstract | Background: Many potential pathogens could be acquired from swimming pool water duringbathing. Hence microbial examination of swimming pool water samples is necessary to ensurethat the water is safe for swimming. As it is impractical to screen all samples for all possiblepathogens, indicator organisms have been used as surrogate markers of risk. Objectives: The study aimed at assessing the physico-chemical (chlorine, PH, temperature)and microbiological conditions of swimming pools and evaluating the compliance ofthese pools with the WHO standard. Methods: A cross sectional study was conducted from February for four months(2016-May2016).A total of 60 swimming pool water samples from 10 swimming pools (6 from eachpool)were collected on a weekly basis for physicochemical and bacteriological analysis usingthe MPN method. PH, residual chlorine and Temperature of the swimming pool water sampleswere measured. In addition, total viable count and coli form count (total coli form, fecal coliform and (E.coli) were determined. Chi-square test was used for association and data wasanalyzed using SPSS Version 20.Results were compared with the WHO recommended limits foreach parameter. Results: The swimming pool water samples had average pH and temperature of 7.1 and 29crespectively.58.4%(n=35/60) of the samples had PH in the range of 7.2-7.8 while58.3%(n=35/60) of samples had temperature in the range of 21c-32c.25%(n=15/60)of theswimming pool water samples had residual chlorine in the range of 2-3mg/l.73.3%(n=44/60) ofswimming pool water samples had a total viable count below 200cfu/ml and 70 %(n-42/60) ofswimming water samples had TCC values less than 2MPN/100ml.More over, 66.7%(n=40/60)of the samples had fecal coli form counts falling bellow 1MPN/100ml.E. coli was present in30%(n=18/60) of swimming pool water samples while it was absent in 70%(n=42/60) poolwater samples. It was also found out that PH and residual chlorine had association with potability while temperature was not. Conclusion: It was observed that 70% (n=42/60) of the swimming pool water samples metthe WHO microbial standard while 30%(n=18/60) did not.
