Abstract

BACKGROUND: From swimming pools, bathers may acquire many potential pathogens or may be affected by the physicochemical characteristics of water used during bathing. Hence, this study aimed at assessing the physicochemical and microbiological quality of public swimming pools located at different hotels and recreation center in Addis Ababa, Ethiopia.

METHOD: A cross sectional study was carried out from February to May, 2016. Nine hotels and one recreation center which recognized to have public swimming services were included. A total of 60 swimming pool water samples from 10 swimming pools were collected at deeper, shallow and intake point twice on a weekly basis using a 250 ml sterile bottle containing sodium thiosulphate. PH, residual chlorine and temperature of samples were recorded at the time of collection. Sample containing bottles were transported in ice box to microbiological laboratory and analyzed on the same day. Standard cultural and biochemical methods were used for isolation and characterization of the main microbial groups. Total viable count, total coliform count, fecal coliform count and

RESULTS: Average PH and temperature of swimming pool water samples were 7.1 and 29

CONCLUSION: PH, residual chlorine and temperature value of majority of the swimming pools' water samples were within the acceptable limit. Regarding microbial quality, most swimming pools' water samples complied to the WHO standard. Swimming pools that did not comply to the standard both in physicochemical levels and microbial quality need improvement due to their significant health implication.
