How is the total number of colonies in swimming pool water exceeding the standard?

Liuzhou News (Reporter Chen Xiaoyan) The reporter learned from Liuzhou Health Supervision Institute yesterday that the institute conducted a "physical examination" on the second batch of swimming places in late July. At present, the sampling results of water quality have come out, and six of the 18 water samples are unqualified. The unqualified indicators are urea and the total number of colonies exceeding the standard.

In late July, the Health Supervision Office conducted the second batch of inspections of swimming places in the city, and sampled the pool water of 14 swimming places. The indexes of free residual chlorine, urea, total number of colonies, turbidity, PH value and coliform bacteria in swimming pool water were detected by Liuzhou CDC. The results showed that 6 water samples from 5 swimming places were unqualified.

The results showed that the total number of urea and bacteria in swimming pool of Jinlang Food Supermarket in High-tech Zone exceeded the standard; The total number of bacteria in the swimming pool (including children's pool and adult pool) of Changhong Machinery Factory exceeded the standard; The urea in the swimming pool operated by Hongfu Property Management Co., Ltd. exceeds the standard; Urea in Hongyang Swimming Pool in Liubei District exceeded the standard; However, the urea in Liuzhou water swimming pool exceeded the standard.

In the second batch of inspections, the Health Supervision Office also re-inspected the Jianpanshan Swimming Pool and Longquan Yinshan Swimming Pool, which were found to have exceeded the standard in the first batch of inspections, and the re-inspection results were qualified.

The staff of the health supervision office said that urea and the total number of colonies exceeded the standard are the most common problems in swimming places. The total number of urea and colonies exceeds the standard, which is related to factors such as the manager's failure to change water as required, the swimmer's failure to take a bath when entering the pool, the swimmer's urination in the pool, and the influence of the surrounding environment.

For swimming places with unqualified water quality, the health supervision office has asked them to rectify and will check again.
