전기비저항법을 이용한 쓰레기 매립장 침출수의 오염확산 탐지기술 개발 = Contamination Mapping and Monitoring Technique for Leachate in Land-fill Area by Using an Electrical Resistivity Method

다국어 초록 (Multilingual Abstract)

An electrical resistivity method was used to provide subsurface contamination ma2ping and monitoring technique for leachate in land-fill area. In order to develop a practical technology the dipole-dipole resistivity survey was employed on the land-fill area model of 10m by 6m in size. The model consists of 5 parallel survey lines, and each line has 19 electrodes. The space between survey lines is lm and that between electrodes is 0.5m.
The background survey was conducted first to get reference data, and salt water was injected at the middle of the area. The field data were acquired on the 5th, 11th, and 20th day after injection.
The result of the horizontal survey data analysis indicates that the location of the pollution source and the diffusion area can be precisely determined, and the diffusion pattern with time lapse can be identified. A 3-D visualization technique is greatly helpful to select the survey lines which are requested to be analyzed precisely.
The result of the vertical survey data analysis indicates that the vertical extent of the pollution can be determined by comparing the survey data with the reference data.
From this study it can be concluded that if the electrodes are implanted and background resistivity survey is conducted before spreading water blocking sheet, the location of the pollution source, and horizontal and vertical extents of the contaminated area can be determined with subsequent resistivity surveys.
