Background and Objectives: Water complexes including Jacuzzi are among the most popular water recreation centers that noncompliance with health standards can lead to increased microbial growth in water and thus the risk of infection. This study aimed at comprehensive study of jacuzzis water in Yazd city and comparing the results with national and international standards. Materials and Methods: This was a descriptive - analytical study that statistical society included all Jacuzzis of Yazd city. Sampling of jacuzzis was performed every two weakes for 3 months (Summer 2011). We tested the water samples for parameters such as temperature, pH, amount of residual chlorine, turbidity, alkalinity, hardness, the population of heterotrophic bacteria, Staphylococcus aureus, Pseudomonas aeruginosa, fecal streptococci, and fecal coliforms accordance with standard methods. The SPSS software and ANOVA, T-test statistical tests, and/or Kruskal-Wallis, and Mann-Whitney were used for description of data and the obtained results were analyzed by comparing with standards. Results: we found that the mean of residual free and combined chlorine was equal to 0.628 and 0.337 mg/l respectively. The alkalinityand hardness were 141.928 and 275 mg/lCaCo3 respectively. Mean of pH, turbidity and temperature were equal to 7.88, 0.457 NTU and 38.121˙C respectively.Moreover, the mean population of fecal streptococci bacteria, heterotrophic bacteria, Staphylococcus aureus, Pseudomonas aeruginosa, and fecal coliforms were 20465.7, 120.77, 209.91 and 7131.4 in 100 ml respectively. Statistical analysis of data showed that there is a direct relationship between water turbidity and pH (Pvalue=0.018) however, population of heterotraphic bacteria and residual free chlorine had indirectl relationship (Pvalue= 0.026). Conclusion: According to the results achieved, the parameters of heterotrophic bacteria population and alkalinity had the least compliance with the standard indicating the need for continuous monitoring of physical, chemical, and microbial parameters of Jacuzzi water and control of the number and density of people using Jacuzzi and continuous monitoring of Jacuzzi water filtration and chlorination process performance.
