Abstract

The Chonju and Samchun streams are passing though Chonju city and several contamination sources are located along these streams. The Samchun stream joins the Chonju stream in the Gosapyeong waste disposal site and the Chonju stream finally joins to the Mankyeong River. The objectives of this study are to determine the state and sources of contamination for heavy metals and anions in the Chonju and Samchun streams and to evaluate the effect of these streams on the contamination of the Mankyeong River. In order to select sampling locations, a stratified random sampling method was used. These sreams was divided into several parts according to the expected contamination state, and samples were selected randomly from these parts. Generally, the water qualities of these streams were generally below the Drinking Water Level at the time of sampling in various heavy metals and anions. However, the levels of A1, Fe, NH3-N, C1- in these streams could be higher during dry season due to continuous inputs from various contamination sources. This study identified several contamination sources for these streams: two waste disposal sites along these streams for Fe, Mn, A1, Zn and C1-, the Chonju Waste Water Treatment Plant for Zn, Mn, C1-, SO42-, NO2-N and NH3-N, and the untreated sewages for A1, Zn, Mn, C1-, SO42-, Fe, Mn, C1- and SO42- in the Mankyung River.
