Abstract
An in-situ method is disclosed for low pressure vaporization and recovery of contaminants from surface and near-surface soil by electrically heating the soil with a pattern of hollow electrodes and pulling a deep vacuum through the electrodes. The surface of the soil is sealed with an impermeable barrier supported by the soil. The contaminants are removed by vacuum distillation in the presence of water vapor at a temperature well below the normal boiling point of the contaminants.
