Water quality standards (WQS) are mandatory to guarantee the human health and protection of aquatic ecosystems, and maintain the condition of suitable water quality. The present WQS for the protection of human health in Korea contain nine substances (As, Cd, $Cr^{6+}$, CN, Pb, Hg, ABS, organophosphorus compounds and PCBs), but it is insufficient to preserve the human and aquatic ecosystem from a variety of chemicals. Therefore, it is necessary to expand the substance of WQS for the protection of human health. In this study, we chose the 20 chemicals from 43 chemicals of the project entitled 'Development of Integrated Methodology for Evaluation of Water Environment'. The methodology for calculating water quality criteria was amended from the US Environmental Protection Agency (US EPA)'s equation for deriving ambient water quality criteria for the protection of human health. The factors including fish intake, drinking water intake, and human body weight used in the equation reflected Korean situations. The monitoring values were derived from the water quality monitoring data in Korean four main rivers. The orders of priorities of chemicals were evaluated by human health risk assessment, and the proposed WQS was derived by technical and economic analyses. These results were reflected to expand the WQS for the protection of human health.
