Combined Use of Remediation Technologies with Electrokinetics

Gomes, Helena I.; Bustos, Erika B.

Abstract

Soil contamination is a global challenge linked to both water and food security. In most cases of contaminated soil, there is not just one contaminant, but a mixture of inorganic and organic pollutants, which hinders the efficacy of remediation technologies. Electrokinetic remediation has been used in combination with other remediation technologies to tackle recalcitrant or mixed contaminations and reduce remediation times, simultaneously increasing cost-effectiveness. This chapter reviews recent case studies where at least two remediation technologies were combined to achieve remediation criteria and fitness for use. Case studies are described, illustrating routes to maximize contaminant removal or degradation, focusing on in situ application. Both bench-scale and pilot studies were considered, examining the efficiency of remediation carried out by combining techniques and the factors that can affect it. Advantages and disadvantages, as well as current knowledge gaps, of these combined technologies are described.
