One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although R F-SVE systems used in previous field demonstrations have had varying d egrees of success, questions remain concerning its viability and cost- effectiveness.

While innovative technologies in remediation need to be developed, so do innovative ways of site assessment. This monograph describes the development, testing, and performance of a new laser-induced fluorescence soil probe. A screening tool for site characterization, this probe has the potential to provide an economical, rapid assessment of contaminated sites.
Cone Penetrometer testing equipment advances the probe into the subsurface. The probe identifies hydrocarbon classes using a multi-channel excitation-emission matrix. This technique facilitates the collection of significant amounts...
