Abstract
Water pollution level of artificial streams, Okgu, Gunja, Jeongwang, 4Ganseon and Siheong, in Shihwa industrial complex was investigated in order to provide the scientific data for water quality management of the streams. COD concentration from Okgu midstream with median value of 62.5 mg/L was the highest level of all sampling sites. At all artificial streams, Ni, Zn, Cu and Cr concentrations from midstream and downstream of industrial region were relatively higher than those of upstream of residential region. The high content of Cr6+ with median value of 0.293 mg/L was determined at 4Ganseon midstream. It was revealed that pollution of artificial streams was caused by intermittent and impulsive discharge of untreated or inadequately treated effluent through the storm sewer from industrial factories. Thus it is necessary to link and treat the stream water into sewage treatment plant. As an effective implementation to manage and improve the water quality of artificial streams, we suggest to pump the treated effluent from near sewage treatment plant into upstream of each artificial stream and irrigate it via artificial streams for waterfront revitalization of Shihwa Industrial Complex
Key Words: Shihwa industrial complex, Artificial streams, Pollutants, COD, Metals
