A method or system for electrochemically remediating a contaminant in a liquid includes combining a liquid including a water-soluble contaminant with an amount of conditioning agent sufficient to create a conditioned solution having a substantially neutral colloidal charge. The conditioned solution is delivered to a flow-through electrochemical reactor and an electrical current is applied to the flow-through electrochemical reactor to produce a first charged electrode and a second charged electrode. The first charged electrode and the second charged electrode are spaced apart from one another by an electroactive gap. The conditioned solution is flowed through the electroactive gap, thereby electrochemically remediating the water-soluble contaminant in the liquid.
