Abstract

Illegal gold mining has increased significantly in Keude village of Krueng Sabee Aceh Jaya subdistrict. This causes environmental damage in the form of waste mercury pollution in the area. Environmental pollution caused by waste needs to be addressed. However, it needs to determine the appropriate method to overcome it by knowing the depth and the spread of mercury waste. This study aims to visualize subsurface conditions in the area of Krueng Sabee to provide information and data on the spread of mercury wastes. By using the method of geoelectric resistivity Schlumberger array, the contamination can be seen below the surface by the resistivity value of the sites. Results from these measurements after inverted using Earth Imager software of Res2Dinv can get a picture and visualize the location of subsurface conditions of the study. The results show that the resistivity value of waste mercury-contaminated soil at the study site ranged from 2–5 Ωm, and waste mercury contamination occurs vertically to a depth of 3 meters.
