[Suwon Ilbo = Reporter Jung Jun-sung] Water quality test results show that Suwon city tap water is safe to drink.

The Suwon Waterworks Office announced on the 17th that as a result of water quality tests on purified water from Suwon's water purification plants throughout last year, all drinking water quality standards (59 items) received 'compliant' determinations.

The Suwon Waterworks Office produced the '2025 Suwon Tap Water Quality Report,' which includes raw and purified water quality standards, water quality test results, tap water production and supply processes, and tap water-related information, and released it to citizens on that day.

While conducting regular water quality tests, there were no instances of non-compliant results against drinking water quality standards throughout last year. Of the 59 drinking water quality standard items, 31 items were not detected, and 28 items all received compliant determinations within water quality standards.

Raw water is tested for 38 items stipulated in the 'Water Source Management Regulations,' including hydrogen ion concentration (pH), total organic carbon (TOC), suspended solids, dissolved oxygen, and total coliform bacteria. Purified water is tested for a total of 59 items: △Microorganisms (3 items) △Health-related hazardous inorganic substances (12 items) △Health-related hazardous organic substances (17 items) △Disinfectants and disinfection byproducts (11 items) △Aesthetic impact substances and others.
