Bacteriological Assessment of Water Quality of Public Swimming Pools in the Accra Metropolis, Ghana
並列摘要
Water is essential for life and in most parts of the world including Ghana it is used for various activities such as drinking, bathing and recreational purposes. The objective of this study was to assess the bacteriological quality of swimming pools’ water in the Accra Metropolis. Five swimming pools were selected randomly and a research team visited the pools to collect water samples and at the same time administer short questionnaires about the characteristics of the pools. The average number of swimmers, swimming bathing loads, average age group of pool users, methods of disinfection, type of chlorine used, recycling, and treatment of the water before and after use were investigated. During the visit, water samples were collected for total coliform, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus counts using the Membrane Filtration (MF) method and cultured on chromogenic media. Most (60%) of the selected swimming pools had a bathing load≤20 per day. The operators of the pools disinfect their pools’ water with chorine but majority (60%) of the pool operators chlorinated their pools manually with powdered chlorine. The 20 water samples investigated show that 48% of swimming pools water was contaminated with S. aureus, 30.4% with Ps. aeruginosa, 20.9% with total coli form and 0.7% with E. coli. The E. coli count found in this study was very low indicating that the selected swimming pools were not feacally polluted at the time of sampling. It is recommended that future studies should use large sample sizes.
