Objective To understand the water quality and health status of swimming pools in Banan District of Chongqing, and to provide scientific basis for further strengthening the health management of swimming places, so as to ensure the health of swimming enthusiasts. Methods The total bacterial count and coliform microbial index of swimming pool water in Banan District of Chongqing were monitored. Results A total of 384 swimming pool water samples were monitored in Banan District of Chongqing from 2018 to 2022, and the overall qualified rate was ${97.12}\%$, the lowest qualified rate was ${90.70}\%$ in 2020, and there was no significant difference in 5-year qualified rate $\left({{\chi }^{2}= {6.395}, P >{0.05}}\right)$. There was no significant difference in the qualified rate of microbial detection in swimming pool water between different seasons $\left({{\chi }^{2}= {4.899}}\right.$, $P >{0.05})$. There was significant difference in the qualified rate of microorganism monitoring in swimming pool water of different types of swimming pool venues $\left({{\chi }^{2}= {17.361}, P <{0.01}}\right)$.
