The Survey about Toxic Material Contamination at the Streamwater around the Sudokwon Kandfill Area

This study estimate the degree of contamination in the streamwater around the Sudokwon landfill site. It was sampled at 10 sites in Jan., Apr., Jul. and Oct., 1996. There were analyzed five kinds of toxic chemical material-CN, AES, PCB, As, Org-p, and four kinds of heavy metal-Pb, Hg, Cd, The result are 1)The COD was generally increased to compare before landfall, 2) The Org-P and PCB were not detected at all points, 3) The concentrations of Pb, and As were lower than the environmental criteria values, 4) The CN, Hg and Cd were over envirommental criteria values. and so emergent regulation is needed, 5) The effects of the streamwater contamination were not only the leachate of the landfall, but also the small factories and agricultural land around the landfill.
