Recently, consumers are requiring not only safe drinking water but also good tasting water. Therefore many water authorities or utilities are using or considering advanced treatment processes for meeting the requirement from consumers. K-water is a nation-wide public company which runs many WTP and multi-purpose dams. As like other utilities, K-water has experienced some complaints from consumers, so it started using drinking water quality grading systems. Currently indices of this system consists of turbidity, taste/odor, chlorine residual, disinfection byproducts (DBPs), geosmin, 2-MIB, Al, Mn. And agreeability standard and Langelia Index have been monitored to be added to the grading system. After K-water set up the agreeability guideline, the governmental organization called the Ministry of Environment in Korea also made a good tasting water guideline in 2006. This paper describes the drinking water quality grading system and agreeability guideline in K-water and the good tasting guideline of the Ministry of Environment in Korea. Includes tables.
