Investigation of Microbiological and Physicochemical Parameters of Water of Abyaran and Laleh Indoor Swimming Pools in City of Hamedan City in 2015

Background: Since the swimming pool water quality as an attractive sports center lead to adverse effects on human heath, in this study, microbiological and physicochemical parameters of water of Abyaran and Laleh indoor swimming pools in city of Hamedan City in 2015 were investigated.

Methods: In this descriptive cross-sectional study, a total of fifty four water samples were collected from the shallow, medium depth and deep areas of two indoor swimming pools. Physicochemical parameters including temperature, pH, turbidity and free residual chlorine were measured on site. All samples were tested for the presence of bacterial contamination by specific mediums.

Results: The mean values of water temperature and pH and also the mean contents of free residual chlorine in 100 percent of samples were lower than the standard levels, while, the mean values of turbidity in 100 percent of samples were higher than the standard levels. Meanwhile, in 100 percent of collected water samples from both swimming pools no microbial contamination to Pseudomonas Aeruginosa and Staphylococcus Aureus were observed and therefore users don't at health risk. While due to the total coliform and fecal coliform in 100 percent and 33.33 percent of analyzed water samples respectively were also found to be above the expected levels, users were at health risk.

Conclusion: Due to the mean values of turbidity and presence of coliform bacteria in analyzed water samples collected from Abyaran and Laleh swimming pools in city of Hamedan City were observed above expected levels, therefore, the quality control of public swimming pool water is recommended.
