Background and Objective: Contamination
of swimming pools’ water can lead to the transfer of different diseases
to humans. The aim
of this study was to investigate the water quality health indicators in Urmia
swimming pools.
Materials and Methods: In this cross-sectional study, 14 active covered swimming
pools in Urmia city were chosen as census. The physical parameters
such as pH, temperature, turbidity and chemical ones such as residual chlorine,
hardness, alkalinity and microbial parameters such as heterotrophic bacteria,
Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus and fecal and
total coliforms were studied. Sampling has been
conducted every weak for 6 months and
they were analyzed under standard procedures. Data were analyzed using descriptive statistics.
Results: In this research, free residual
chlorine in %67, turbidity in %89.9, amount of pH in %83.8 and temperature in
%76.2 of the samples were desirable. In none of the pools, fecal coliform,
fecal streptococcus and staphylococcus aureus were
above the threshold levels. The populations of heterotrophic bacteria,
Staphylococcus aureus, and Pseudomonas aeruginosa in %69.96, %98.8, %85.1 of
the samples were desirable, respectively. Statistical analysis indicated that
there is a direct relationship between water turbidity and the population of
bacteria and reverse relationship between the residual chlorine and the studied organisms(r=-0.595, p<0.005)
Conclusion: According to the results,
complete compliance of the pools to the standards was fairly poor. It is also
important to maintain the proper level of free residual chlorine and pH in the
swimming pools to ensure safety of the water quality.

Funding: This research
was funded by Mazandaran University of Medical Sciences.
Conflict of interest: None declared.
Ethical approval: The Ethics Committee of Mazandaran University of Medical Sciences approved
the study.
