The aim of this research is to measure the quality of environmental health of recreational and natural sports swimming pools with a risk management approach in Gilan Province. The study was descriptive - cross-sectional, and three selected sites were sampled. Microbial parameters, temperature and PH were measured. Microbial tests were carried out according to national standards in the laboratory. It was used to analyze data from standard tables related to pollutants and compare them to existing data. SPSS software was used to analyze data from experiments. Two William fine quantitative methods and the risk assessment table technique were used to assess risk. The results showed that the burden of microbial contamination in the Anzali swamp was higher than other sites. In other words, the most polluted sites in Gilan Province were the Anzali wetland, the Kiasar wetland and, at the end, the eyeglass wetland, respectively. Also, the average number of total cliform and cliform, respectively 375 and 109 MPN in 100 ml of samples, and Enterococcus of the rivers 7/17 CFU in 100 ml of samples were observed. The average pH was 89/7, which is within the standard range. On the other hand, the average water temperature measured in these natural swimming pools is 4/25 degrees Celsius, which is within the standard range. It was found that the type of risk "outstanding", the level of aspect "ultimate" and the control required were "appropriate control action and the necessity of corrective action".
