Study of the Pollution Condition of Swimming Pools in Sari City for the Staphylococcus aureus

Backgrounds and Swimming pools water if not disinfected properly can be one of the infection sources of different microorganisms such as staphylococcus. This study is to aware the authorities and users about the conditions existed in sheltered swimming pools in Sari and to believe the contamination of the water there, related to the existence of staphylococcus aureus. In this descriptive study 32 specimens collected randomly from 15 swimming pools in action during three months from 60 cm deep under specific conditions in sterile containers and taken to the laboratory of health college in 2 hrs and were analyzed for the contamination from staphylococcus aureus and some other parameters like temperature, pH, chlorine residual and opacity on the basis of microbiological and standard methods. Results showed an average temperature of 27.08 degree Celsius, PH=7.6, average chlorine residual 1 mil/l and opacity average was 77 NTU % and the highest contamination from staphylococcus aureus (29.3 %) in C and the lowest (10.19 %) was observed in D swimming pool. Furthermore this analysis showed that in 90% of specimens there was a direct relationship between the ratio of chlorine residual, times of swimming, water temperature and the number of staphylococcus. Swimming pools water if not disinfected properly can be one of the infection sources of different microorganisms such as staphylococcus. Some suggestions inorder to optimization of the swimming pools condition presented in this paper.
