Background: Poor quality of water in swimming pools may cause health problems and transmission of infectious diseases to swimmers. The aim of this study was to study the status of Water Quality Health Indicators of the swimming Pools in Tehran in 2015. Materials and Methods: This cross - sectional study was conducted in the 24 pools (n=288) in west of Tehran. Residual chlorine, temperature and pH were measured in field and microbial tests according to standard protocols. The SPSS software was used for data analysis. Results: Average residual chlorine, pH, pool and Jacuzzi temperature, were calculated as 1.7 ± 1.05, 7.70 ± 0.24, 26.92 ± 0.97, 39.39 ± 1.48, respectively. Heterotrophic plate count (HPC) in 5.21%, total coliforms in 9.4% and fecal coliforms 17% of the samples were above the standard level. A significant but inverse correlation between residual chlorine and HPC, total coliform and fecal coliform were found. Conclusion: Results showed that the Water Quality Health Indicators of the Swimming Pools in more than 80% of pools as compared to standards is at desirable and expected levels. To improve the sanitary conditions of other pools, standards compliance and sanitary requirements and regular and periodic monitoring of above indicators is necessary.
