World-renowned water quality manageme

Seoul Water Institute(SWI) has managed water quality in a systematic and scientific manner to ensure that Seoulites drink safe water through meticulous water examination for samples taken from water sources to taps.

SWI monitors the water in the five intake stations, six water treatment plants, and the distribution systems. Certain water quality parameters are monitored continuously as the water enters the distribution systems, and We regularly tests water quality for a broad spectrum of microbiological, chemical, and physical measures of quality. In 2016, SWI performed more than 100,000 analyses for over 10,000 samples taken from source to taps throughout the City, meeting all the National and City’s monitoring requirements. Results of these regular monitoring are an indicator of whether drinking water meets all health-based and aesthetic drinking water standards. The results are regularly open to the public on the website of the Office of Waterworks. For more information, please visit: http://arisu.seoul.go.kr/sudo_eng/index.jsp

Ensuring safe and reliable water quality

Regular monitoring Parameters

SWI’s water quality monitoring program – far more extensive than that required by law – demonstrates that the quality of Arisu, the drinking water for Seoulites, remains high and meets all health-related Korea and Seoul City’s drinking water standards. Arisu is regularly tested for 164 constituents/contaminants including 59 regulatory parameters of the National Water Quality Standards enforced by the Ministry of Environment and 105 monitoring parameters designated by Seoul Metropolitan Government.

Research on unregulated emerging contaminants

We have been conducting research and monitoring to identify, understand, and evaluate unregulated contaminants since 2007. Target compounds are known as Endocrine Disrupting Chemicals and Pharmaceuticals & Personal Care Products, which are considered to be emerging contaminants. SWI has voluntarily participated in national research studies and established analytical capabilities. We will continue to strive to stay at the forefront of this issue to ensure the safety of Arisu and the protection of our watershed.
