Measured with “4-point-light hp” and “ActEle” active electrodes manufactured by Schwartech (formerly LGM - Lippmann Geophysical Equipment). Measurement software Geotest.

• investigation of an old waste deposit
• 50 electrodes, separation = 4 m
• Measurement configurations = dipole-dipole and wenner
• 1143 measurements, 34 min measurement time required
• Measurement of resistivies (using dipole-dipole) and phase angles (using wenner) as well

Calculated with Res2DInv inversion software.

• Iterative and fast inversion technique
• Calculates model resitivities and model phase angles
• Calibrated using borehole profile
• interpreted depth section shown
