Abstract

The electrokinetic treatment method was employed to reduce the salinity level in the soil samples taken from the Dardanos District of Çanakkale, Turkiye. The coastline of the region suffers from saltwater intrusion due to uncontrolled pumping out of groundwater for domestic usage and agricultural activities. Thus, the salinity level increased and much land became unusable. The study area has silty agricultural soil. Its pH value is 8.33, electrical conductivity (EC) is 1282 μs / cm and NaCl equivalent is 0.45%. In the lab-scale experiments, three rows of electrode pairs were placed in the plastic container. Current variation was monitored while 1 VDC/cm was applied to electrodes. Average electrical conductivity reduces to 13.5%. As a side effect, destructive corrosion occurred in all electrodes.
