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.

A part of the continuing effort to provide innovative in situ remediation techniques, Remediation of Firing-Range Impact Berms presents the results of a soil washing and leaching project. The demonstration set as its primary objective providing reliable, detailed performance data to evaluate the feasibility and cost of implementing a full-scale system. Its secondary objective was to demonstrate the effectiveness of the technology in producing a 'clean' soil based on analytical results.
The project included the following steps:

Bench scale treatability studies of prospective...
