Abstract

The water quality survey was conducted from August 2009 to June 2010 in 84 swimming pools in the HCM city. The purpose of the survey was to investigate the current status of water quality at public pools and propose appropriate management methods. All swimming pool water samples were taken from Monday to Friday, of which 9 pools were more surveyed on the weekends, to analysis carefully for chlorine residual, pH, chloramine, temperature, and total Coliforms. Results showed that 100% pool violated in temperature and residual chlorine, 71-77% pool violated in pH indicators; 29-35% pool had chloramine concentration over 0.2 ppm and 82-100% pool were contaminated by micro-organisms on the weekends. From the above results the authors proposed some management measures to improve water quality in public swimming pools in HCM City.
