Background & Objectives: Water of swimming pools can be polluted by some materials of the swimmers bodies such as hair and respiratory microbial flora. Insufficient water treatment process will be a possible vector of infectious diseases to the swimmers. This study was performed to assess the biological quality of Ayoub hot spring.

Material & Methods: The present study was a descriptive cross sectional. The samples were obtained twice per month from Ayoub public hot spring pool in 3 months during June to August. Temperature, pH, ORP, DO, EC, turbidity, free chlorine were measured on-site sampling. Standard methods were used to examine the samples for the total and fecal coliforms such as P. aeroginosa, S.aureus, and HPC. Finally, the data were analyzed using the Excel and SPSS- 16 softwares.

Results: The average of temperature was higher than that the standard and the average of pH was about standard. Most pollution by the coliforms was during the July and August. The P. aeroginosa was also the most important pollutant on June.

Conclusion: Pollution of hot spring in some of the seasons is higher than that the standard. Therefore, it is suggested that the monitoring and disinfection of the public hot spring pools should be considered more seriously. It is also necessary to limit the number of swimmers in public hot spring pools to reduce ratio of contamination.
