Abstract

Background: Due to the wide use of swimming pools and the necessity of maintaining the health of swimmers and controlling health issues, management and monitoring of such sites are necessary and necessary for compliance with established standards by competent authorities. The aim of this study was to evaluate the physicochemical and bacteriological indices of swimming pool water in Zanjan in 1995
Materials and Methods: This study was descriptive-analytical and all of the active swimming pools were sampled during the summer and autumn seasons. Physical and chemical parameters such as air and water temperature, turbidity, residual free chlorine content, electrical conductivity, oxidation and regeneration potential (ORP) and bacteria including total coliforms and fecal coliforms, plate counting of heterotrophes, stool streptococci, Staphylococcus aureus and Pidmonas Aeroginosa was studied
Results: Among the microbial parameters of Pseudomonas aeruginosa and fecal coliforms, the plate count of heterotrophs was 64%, 26.9% and 12%, respectively, and were at an unsatisfactory level compared to the standard. This indicator was obtained for parameters of turbidity, water temperature, air, pH and free chlorine 98%, 94%, 88.9%, 79.6%, 41.7%, respectively
Conclusion: Physicochemical and bacterial parameters are in poor compliance with the national standard. Trainers instructors and managers of swimming pools are responsible for basically exploiting pools, implementing retraining courses for health inspectors, controlling routine operation and interventional parameters such as turbidity and temperature, and Effective on the disinfection process and the use of digital and up-to-date digital imaging devices has a significant impact on the water quality of the pools
