Ulsan's Tap Water Satisfies All Criteria of Drinking Water Quality Test
According to a water quality inspection for water purification plants and faucets conducted by the Waterworks Headquarters of Ulsan Metropolitan City in March, Ulsan's tap water was found to be very safe, meeting the drinking water quality standards of the Republic of Korea and the drinking water quality guidelines of the World Health Organization (WHO) for all 60 test items.
In the case of purification plants, the test results for microorganisms such as general bacteria and E. coli and the test for harmful inorganic substances including heavy metals all showed results of Not Detected or Within Standard.
18 harmful organic matters including phenol and benzene were Not Detected, and 11 items including residual chorine, chloroform, and bromate were found to be Not Detected or Within Standard.
In addition, 16 aesthetic items including hardness, smell, taste, color, turbidity (0.5NTU and below), pH, chlorine ion, lye, manganese, and zinc were found to be Not Detected, Satisfactory, or Within Standard.
Ulsan selected a total of 108 general households considering the gu/gun population by water supply. As a result of a water quality test on home faucets and the faucets of outdated pipes in four purification plants, residual chlorine fell into the acceptable range and met the water quality standards on all points.
In addition, necessary substances for the human body such as iron and zinc, which are not harmful inorganic substances but aesthetic items, varied depending on the region but were found to be safe and well within the standard.
According to a regular water quality check, tap water supplied from purification plants to households was well within the drinking water quality standards of the Republic of Korea and the drinking water quality guidelines of the World Health Organization (WHO). As Ulsan tap water has been certified to be safe and clean, citizens can drink it with peace of mind.
The Waterworks Headquarters of Ulsan Metropolitan City produces and supplies around 350,000 tons of tap water per day.
