PENENTUAN KONTAMINASI LIMBAH CAIR DENGAN METODE GEOLISTRIK

Abstract

The research area was done at Basic Science Laboratory Lambung Mangkurat University, about the spread of liquid waste contamination. This liquid waste was estimated from chemical liquid residue. The data acquisition was carried out on 17September 2006 in good weather. The measurement method based on the soil/rock electrical property withPole-Pole configuration at 8 x 8 meter areas. The inversion result is vertical cross section under surface area with clay and silt soil contains liquid and mud. The resistivity values obtained were in the range of 0,29-10,63 Ωm with 0–12,3 meter depth. The Spread of liquid waste was estimated up to 6 meter away to x direction and 8 meter away to y direction. The depth spreading was 7 meter from surface with resistivity values of 0,29–3,00 Ωm.
