Seoul City has been conducting drinking water quality standard tests for its tap water ‘Arisu’ on 170 criteria, which exceed the number of criteria (163) as recommended by the World Health Organization (WHO). Among the 170 criteria are 60 on drinking water standards and 110 from Seoul City’s own internal criteria for observation. According to the outcome of research from last year, Seoul City has successfully passed the conformity assessment in all criteria of drinking water quality standards for all the districts of Seoul.

Seoul City is in the process of conducting detailed and comprehensive examination for every stage of water quality control, from the upper region of the Hangang River which is the source of water intake, to all Arisu distillation centers, autonomous districts, and water faucets in general areas, for safe drinking water quality control. Meanwhile, Seoul is providing various drinking water-related policies and information for citizen participation through its Arisu Quality Report, and more information can be found on the Arisu website (http://arisu.seoul.go.kr).

In addition, those who are curious about tap water quality provided to their homes may receive a free water quality test and a check-up or verification on the status of their water pipes (Dasan Call Center 120).
