There was no significant change in the five years（x^2 = 8.27 ,P〉0.05）,but there was significant differences between different pools（x^2 = 21.30 ,P 〈0.05）. In all the monitoring projects,the lowest pass rate of free residual chlorine was 78.16%. Conclusions The qualified rates of swimming pool water in 2005-2009 were relatively low.
