Figure 2 - Electrodes in place before power is applied. Figure 3 - After remediation with electrodes removed. Recovery of ionic contamination from ground and ground water is limited by the fact that soil is a powerful ion exchange media.
Ionic contamination becomes adsorbed on soil particles following contact.
Flushing alone will not recover it. A pH shift must be applied to desorb and mobilize it. However, flushing with strong acids usually destroys the basic soil structure. Our technology was developed to address these issues in an elegant and practical manner, which avoids denuding or destroying the soil structure. Each casing has an electrode inside.
