In addition, new town construction for residence is planned for the future. Therefore, the survey was carried out to determine the probability of soil contamination.
Soil contamination survey was performed sampling and analysis according to Korea standard method for soil. Analysis parameters were selected as TPH(Total Petroleum Hydrocarbon), Zinc, Fluorine, Copper, Mercury, Arsenic on the basis of result from proceeded overall survey of the site. As a result fluorine contamination has emerged in most investigated points, and some points has TPH and arsenic contamination exceeded the standard measures. Mercury and copper were not detected. Almost of regional classification for land use are arranged by ‘2’ or ‘3’ areas. However, this district would be expected to change the regional classification as ‘1’ area which is for housing site. Therefore, the remediation and detailed investigation aimed at this district should be conducted.
