Abstract
Potential differences measured on the surface were used in an attempt to<br>monitor the movement of a low-volume tracer. The experiment was conducted<br>in the unconfined groundwater aquifer at Haslemoen, in Hedmark County,<br>Norway. 300 1 of NaCl solution were injected at a depth of 4.1-5 m. A pole-dipole<br>electrode configuration was used, with the near current electrode embedded in<br>the zone of injection. The direction of tracer movement was identified. The<br>measurements are affected both by the moving conductive zone and the changes<br>in electric current concentration.
