Bacteriological Count and Chlorine Assessment of Water Quality of the Public Swimming Pools in Klang Valley Malaysia

Abstract Background Water is essential for life and has been used for various activities such as drinking, bathing, and recreational purposes and is one of the modes of the transmission of the disease. Objective This study aims to assess the bacteriological count and chorine level of swimming pools’ water in Lembah Klang, Malaysia. Methodology: Seven water samples were collected from outdoor and indoor swimming pools (hotel, apartment, and public swimming pool) in Lembah Klang, Malaysia. Water samples were collected in sterile bottles (30 ml). Physicochemical parameters were determined using a water quality testing kit pH & chlorine apparatuses. The water sample was cultured and incubated. The presence of bacteria was counted by the total bacterial count method. Result The mean values of the various chlorine level parameters of the selected water samples investigated for the apartment, hotel, and municipal were 0.56 ± 1.01, 0.77 ± 0.95, and 1.19 ± 0.91. The chlorine level except conductivity values were within the permissible limits of the World Health Organization (WHO) standards 2006 and American National Standard for Water Quality in Public Pools and Spas (ANSI/APSP) 2015. The mean, standard plate count of water samples from the selected apartment, hotel, and municipal’s swimming pools were 28407.14 ± 28469.05, 8192.86 ± 10556.36, and 3257.14 ± 6250.17which above the WHO Guideline limit, thus signifying contamination. Conclusion The study recommends improvement in the personal hygiene of swimmers, adequate cleansing of the pools, and enforcement of standards by the government.
