ABSTRACT: Soil contamination with hazardous substances can be in solid or
liquid forms such as petrochemicals or chlorinated solvents hydrocarbons.
Contaminants in soil can be physically or chemically adsorbed to soil grains or only
trapped in pore space. Soil contamination usually occurs through spillage or burial
directly at the contaminated area or migration from a spillage or burial source
occurred elsewhere. Some of most occurring sources of soil pollution are
petrochemical and chemical contamination. This study investigates the use of
electromagnetic (EM) waves with various radiation patterns to induce a controlled
transportation of a nonhazardous dye (used as contamination simulant). The medium
in this study is aqueous (i.e., water), which helps to monitor the contaminant simulant
transport under EM stimulated conditions. EM waves can be launched into the
medium at proper frequencies to minimize the heat generation and temperature
increase, yet induce a transport according to the EM radiation pattern. Then, the
contaminant-simulant transport under EM-stimulated and unstimulated conditions
were studied, and the results suggest that dielectrophoresis can be the underlying
