Arisu acquired the ISO 22000 international certification (Food Safety Management System) from the International Organization for Standardization on November 22, 2016 and has been recognized as a safe food worldwide. The Seoul Metropolitan Government published the 2016 Arisu Quality Report on May 2017 to reconfirm the outstanding water quality of Seoul’s tap water.
Arisu Quality Report is a ‘water quality report’ that informs the water quality of the water source at the upper Hangang River, the Arisu Purification Center, autonomous districts in Seoul and tap water. It contains reports on water quality analysis on 170 items, which is more than the 163 items recommended by the World Health Organization (WHO).
No pathogenic microorganisms were detected and the water was free of 26 harmful substances including lead, arsenic, cadmium, phenol and parathion. Disinfection by-products generated were detected at 1/5 of the water quality standard.
The Arisu Quality Report also contains other useful information such as the Arisu Quality Certification System. Read the report at the website of the Office of Waterworks Seoul Metropolitan Government (http://arisu.seoul.go.kr).
