Abstract
ABSTRACT To data, there was no systematic basis for establishing the content and allowed levels of general contamination substancesin the Korean groundwater quality standards for non-drinking water. Recently, use of specific procedures for deriving validgroundwater quality standards have become mandatory. This study first investigated the methodology for derivinggroundwater quality standards in the European Commission (EC), considering background groundwater quality anddomestic and international standards related to water quality. Furthermore, this study investigated the existing specifiedprocedure of standards related to water quality (e.g. surface water, drinking water, and wastewater). Our findings showedthat EC and Member States presented the methods for deriving groundwater threshold values for general chemicals.Finally, we have proposed the following procedures of deriving Korean groundwater quality: (1) Selection of groundwaterpollutant population, (2) selection and monitoring of priority substances, (3) monitoring, (4) selection of groundwaterquality standard candidates, (5) selection of new substances and values for groundwater quality standards.Keywords : General contamination substances, Groundwater, Water quality standards
