particular, the efficacy of electrokinetic remediation depends strongly on characteristics of con-
taminated media such as buffer capacity, mineralogy, and organic matter content, among others
(Reddy and Cameselle, 2009a).

5.2.3.5 Advantages and disadvantages of electrokinetic technology
Electrokinetic remediation has been considered as a promising technology because of its unique
advantages over other conventional technologies (Oonnittan et al ., 2009; Reddy and Cameselle,
2009a). These advantages include:

• Flexibility to use as ex-situ or in-situ method.

• Applicability to low-permeability and heterogeneous soils.
