This study was investigated the distribution characteristics of heavy metal concentrations in soils around abandoned mines in Pochon city. The abandoned mines were Youngjung, Yongsog and Pochon. The results were as follows:<br/> 1) Heavy metal mean concentrations in minewastes were detected Cr 100.119 mg/kg, Cu<br/> 189.400 mg/kg in Youngjung mine, Cr 198.440 mg/kg, As 160.480 mg/kg in Yongsog mine and Cr 84.680 mg/kg, Zn 50.280 mg/kg in Pochon mine.<br/> 2) The mean concentrations in soils which is around mines were Cu 62.351 mg/kg in Youngjung mine, and As 95.024 mg/kg, Hg 11.279 mg/kg in Yongsog mine. All materials in Pochon mine were detected low level.<br/> 3) The concentrations of heavy metal showed low or not detected in water system<br/> (ground waters, streams and sediments).

The objective of this study is to evaluate and analyze Sincheon basin water environment system. The data were collected from 2010 August to 2016 December including BOD, SS, T-N, T-P. The results were as followed. As the result of comparing the amount of BOD generated by pollution sources in the Sincheon water system, industrial was the highest at 33,259.4 kg/day. In comparison with the tributary, it was estimated that Dong-Du water system reveals the highest level of BOD in the industry. Population and livestock was high in CheongDam and Sang-Pae water system. With the inflow stream of Hyo-Chon, Suk-Woo and Sang-Pae, the pollution degree of BOD and T-N level of Sincheon increased and pollution degree of tributary was higher than that of Sincheon’s main stream. The main reason of pollutant of Suk-Woo was from untreated wastewater, and it influenced downstream of Suk-Woo. Hyo-Chon stream satisfy the water quality standard, but Zn was designated as a Monitoring contaminants, was high as 14.670 mg/L (standard 0.02~2.45mg/L)because of textile wastewater. And Sang-Pae stream was polluted by livestock wastewater of livestock farms as a nonpoint source.
