The lands stretching at the shorelines suffer from salinization which is one of the main environmental problems. Removing harmful salt contaminants requires an excessive amount of effort. The electrokinetic remediation (EKR) of soils away from urbanization is challenging since it requires a constant power supply. This research investigates the field scale effect of imposed electrical gradient (IEG) for the removal of salts from the soil with EKR using a solar panel-driven power supply. The testing soil was sampled in the Çanakkale-Dardanos Campus (CDC) area, in northwest Turkiye. The land in the CDC suffers from extreme saline water intrusion due to the excessive pumping of fresh water from multiple wells scattered in a relatively small area. The initial concentrations of salt ions were determined. Ca2+ showed the highest concentration (60,300 mg/kg) followed by Mg2+ (16,000 mg/kg), K+ (13,800 mg/kg), and Na+ ions (12,600 mg/kg). The most abundant anionic salt concentrations were Cl− (674 mg/kg) and SO42− (118 mg/kg). Lab-scale EKR studies showed that the EKR requires a minimum of 5-days to achieve satisfactory results. Therefore, we propose a mobile solar panel system and EKR as an innovative, sustainable, and environmentally friendly alternative to apply the EKR technology to saline soil. We will focus on designing the power supply system and fluid circulated electrodes. The results will be presented in due course.
