Ulsan Institute of Health and Environment Conducts Tests on 9 Items
The results of water quality tests for swimming pool water at public swimming pools in the Ulsan area showed that all pools met the water quality standards.
The Ulsan Institute of Health and Environment conducted water quality tests on a total of 109 samples from 14 public swimming pools in Ulsan (4 in Nam-gu, 2 in Jung-gu, 4 in Buk-gu, 1 in Dong-gu, and 3 in Ulju-gun) from January to August this year to determine compliance with water quality standards.
The tests covered a total of nine items, including turbidity, potassium permanganate consumption, total coliforms, and heavy metals.
In the results, six swimming pools showed free residual chlorine concentrations that were slightly higher or lower than the standard, making them initially non-compliant, but they passed upon retesting.
Free residual chlorine refers to chlorine that remains in the water after disinfection, existing in the form of hypochlorous acid and hypochlorite ions.
An official from the institute stated, "We will do our best to ensure water safety by conducting water quality tests quickly and accurately so that citizens can enjoy leisure activities in safe and hygienic swimming pools."
Facility operators are required to conduct water quality tests on swimming pool water at least once every six months. Test results must be posted in a location around the pool that is easily visible to users, and pool water should be replaced at an appropriate time based on the test results.
