Abstract

An integrated electrochemical soil remediation method and apparatus for treating contaminated soils (10), especially those contaminated with mixtures of nonvolatile organic contaminants, ionic contaminants and volatile organic compounds are disclosed. Remediation may be achieved by electrochemically enhancing biodigestion of organic contaminants (using microorganisms present in or added to soil), electrochemically removing ionic contaminants and electrochemically removing volatilized organic contaminants by applying a vacuum over the soil being treated, as dictated by the nature of contamination. Physicochemical conditions of the electrolyte and the soil are managed by monitoring and adjusting the electrolyte (35). Nutritional needs of microorganisms for biodigestion are adjusted as necessary through the electrolyte (37).
