The discharge characteristics of Volatile Organic Compounds (VOCs) from seven wastewater treatment plants and two industry drains at Nakdong River basin were investigated. Four Sampling campaigns were conducted between May 2008 and November 2008, and tested for 17 VOCs. As results, eight VOCs were detected at some sampling sites, but their concentration levels were low; 0.19~3.41 ${mu}g/L$, dependent on each sampling location and substance. However, proper management plans such as supervising and monitoring systems for VOCs are needed to control those pollutants since VOCs might affect human health as well as aquatic ecosystems with extremely low concentration levels.
