Abstract

The electrical resistivity method is an effective geophysical tool to detect subsurface contamination because the contaminated zones show generally lower electrical resistivity. In this study, the electrical resistivity surveys were applied to a waste landfill site to image the subsurface structure around the landfill and to identify the contaminated zones. First, the dipole-dipole 2D resistivity surveys were conducted along the boundaries of landfill to define the developed contaminated zones. Then the crosshole resistivity tomography was applied to confirm the suspected contaminated zones at depth. The results of drilling and geochemical analysis of ground water supported that the low resistivity zones coincide well with the contaminated zones and the leachate pathways could be delineated effectively from the resistivity survey.

환경오염부지의 오염원은 대부분 전기비저항이란 고유물성과 상관관계를 보이기 때문에 전기비저항 탐사는 지중 환경오염조사에 매우 효과적인 방법이다. 이 연구에서는 폐기물 매립장 주변에서 전기비저항 탐사를 수행하여 매립장 주변 지역의 하부 지질구조를 규명하는 한편 침출수 존재 여부 및 영향 범위를 파악하였다. 또한, 주변 관측정의 수질분석 결과와 전기비저항 탐사의 연관성에 대해 분석하였다. 그 결과, 전기비저항 탐사는 수질분석 자료와 매우 높은 연관성을 보였으며, 시추조사 결과와도 상당히 일치하는 것을 확인하였다.
