Abstract
The purpose of this research is to evaluate the efficiency of soil pollution investigation conducted at South Korea and Gyeonggi-do, and to drive the way to improve its efficiency. The average pollution discovery rates in the soil pollution investigation were 2,7% in South Korea and 1.9% in Gyeonggi-do respectively during the last six years (2002${\sim}$2007), which the discovery rates were lower than those of Japan and United States of America. The exceeding rate of the Korea soil pollution standard of the heavy metal and petroleum compounds in the soil pollution investigation were 89.8% and 8.9%, respectively in the whole country. The investigation rate of topsoil for heavy metal and deepsoil analysis for petroleum compounds analysis were 38% and 62% respectively. This show contradictory result which is demanded the improvement of investigation method on the deep soil. The main steps affecting the discovery rate of soil pollution were site selection step, sampling step and analysis step. We suggested the the guideline of priority on the site selection step which was the most important step. Also, the certificate need to be provided to the companies which have lower soil pollution degree after conducting the soil pollution investigation.
