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