Abstract
A method and apparatus for removing volatile contaminants from contaminated soil is provided wherein the contaminated soil is excavated and stockpiled upon a vapor-tight support structure. The contaminated soil is covered and sealed with an impervious vapor-tight liner such that a vapor-tight enclosure is created. A vacuum is created in the vapor-tight enclosure which induces air flow through the contaminated soil to volatilize contaminants from the contaminated soil. Vapors created as a result of the induced air flow are exhausted from the system and treated or managed as required by federal, state, or municipal regulatory requirements.
