To consider environmental characteristics in the scope of geochemistry of streams, Hwasun area,soil, sediment and water samples near/in the streams were analyzed in texture and metal contents of soil and sediment and in quality in water. From those analyses, the soils are loamy sand,sandy loam, loam and silty loam in texture.And, the sediments are sligments are slightly gravelly sand, gravelly and gravelly muddy sand in facies. Metal contents in soils and sediments are of high near Hwasuneup and Hwasun conlfield. In peculiar,P,Co,Li,Ni,Zn and Pb exceed over crust mean contents. Physico-chemistry of above streams according to pH-Eh and piper`s diagrams indicates that the streams are, typically, assigned to natural river water. Water qualities of BOD,T-N and T-P in areas near Hwasun coalfield,Dongmyeon and Hwasunneup are polluted over V level. Environment factor(EF) representing metal condensation in P,Cu, Zn and Pb appear near Hwasun coalfield and Hwasuneup from the soil and sediment samples, in part. Additionally, river water in dry season is very high in BOD,T-N,Na^+ and SO_4^2-. It is suggested that the relatively high metal contents is the stream be connected with above coalfield and urban areas.
