Comparison of the passing rate of all the samples of different types of swimming pools and the qualifications of each item of water quality. Measurement data were compared using t test, count data were compared using χ ~ 2 test, P <0.05 for the difference was statistically significant. Results A total of 80 water samples were collected from the swimming pools and stadiums in Binhu District of Wuxi City during 2013-2015, of which 48 were qualified and the overall pass rate was 60.00%. The pass rates in each year were 52.00% (13/25) and 60.00% (respectively) 15/25), 66.67% (20/30). In 2013-2015, a total of 46 samples of public swimming pool water were collected, of which 20 were qualified (43.48%); 34 were water quality of swimming pools in hotels and 28 were qualified (82.35%). The qualified rates of water quality monitoring in the two types of swimming pools were statistically different (χ ~ 2 = 12.31, P <0.05). The indicators for monitoring the water quality of swimming pools in Binhu District in Wuxi in 2013-2015 are as follows: turbidity (100.00%), p H value (98.75%), coliform bacteria (93.75%), total number of bacteria %), Urea (62.50%), free residual chlorine (56.25%).
