Introduction: Swimming pools are one of the most important sport and recreational areas where health tips must be followed, or adverse results would threaten the health of the whole society. Objective: The aim of this study was to identify and evaluate the health and hygienic status of the swimming pools as well as water health status in public pools in Mashhad in the first nine months of 2018. Methods: This practical research has been carried out to identify the relevant risks, as field observations for assessing the hygienic condition of indoor areas in 64 swimming pools For data collection in the present study, valid and reliable questionnaires of general information and human resources (14 question), health assessment (37 questions), and water quality control of Mashhad’s swimming pools were used. Parametric analysis of variance was utilized for normal data, and non-normal data were analyzed by Kruskal-Wallis nonparametric test by considering P <0.05. Results: The results of the evaluation of water quality by health centers indicated that the desirability amount of the residual chlorine, water pH, water temperature, water turbidity, microbial thermophile coliforms, heterotrophic bacteria, and water chemical quality was 86%, 96%, 95.44%, 92.44%, 96.49%, 94.96%, and 95.31%, respectively. Amount of the residual chlorine, water turbidity, and heterotrophic bacteria was below the expected level of 95%. The outcomes of the tests administered by Mashhad health and hygiene centers (supervision organization), and pool managers' self-control examinations revealed that the results of water pH, water temperature, thermophile coliform, and water chemical tests were in total accordance with standards (P <0.05). Conclusion: The results showed that most of the health risks were related to the residual chlorine, turbidity, and microbial contamination of water by heterotrophic bacteria. Training swimmers and hygiene culture development have a pivotal role in controlling health risks

Background and Aims: Swimming pools and Jacuzzis as sports and recreational centers are used by many people in different ages and classes. The aim of this study was to investigate the relationship between physicochemical characteristics and microbial contamination in Jacuzzi water and swimming pools in Golestan province. Materials and Methods: In the present cross-sectional study with descriptive-analytic approach, eight indoor swimming pool and Jacuzzi were chosen to be investigated in the Golestan province. Biological (Total coliform, E.coli, Streptococcus, Pseudomonas) and physiochemical parameters (temperature, pH, turbidity, free chlorine residual) were performed according to standard methods. Results: The obtained results showed a significant and positive correlation between turbidity and Pseudomonas in swimming pools (p=0.017). However, no significant relationship was observed between turbidity and other microorganisms. Also, it was revealed that there was a significant and positive correlation between total coliforms and fecal streptococci in the Jacuzzis . Beside an inverse relationship was found btween the free residual chlorine and indicator organisms. Conclusions:There is a high dispersion between microbial contamination and physicochemical variables in pools and Jacuzzis. In other wordو pools and Jacuzzis are very clean on some days and on some others, they are too polluted from the aspect of microorganisms’ presence and turbidity.. This indicates that there is no appropriate operation for pools and Jacuzzis in proportion of swimmer numbers and disinfection rate.
