Abstract
Background and Objectives: Poor quality of water used in the swimming pools can cause several fungal, parasitic, bacterial and viral diseases. Therefore, the aim of this study was to evaluate the water quality in the swimming pools and Jacuzzis in Tabriz.
Materials and Methods: In a descriptive and cross-sectional study in 2008, among 22 swimming pools and 17 Jacuzzis in Tabriz, 11 and 8 pools and Jacuzzis were respectively selected. The samples were analyzed for pH values, coliforms and residual chlorine. All sampling and laboratory analysis were carried out based on standard methods of examination of water and wastewater.
Results: The mean concentration of residual chlorine and coliform in the water of Jacuzzis was 0.075 mg/L and 7.1, respectively. These values were significantly different from the standard values (P≤0.05). On the other hand, the mean concentration of the residual chlorine and coliform in the swimming pools were 1.75 mg/L and 2.14, respectively, which had no significant difference from the standard mean values (P≥0.05). The mean pH values of the swimming pools and Jacuzzis were 7.71 and 7.82, respectively. These values were not different from the standardized mean values (P≥0.05).
Conclusion: The residual chlorine and coliform values in the swimming pools were consistent with the mean standard values. However, the mean values of the residual chlorine and coliform in the Jacuzzis were not in compliance with the standard values. Therefore, further attention should be paid to the Jacuzzis water. Moreover, all the samples were favorable in terms of pH values.
