Zusammenfassung:An apparatus and method for sampling sub-surface soil gas samples and detection of distinctive chemical tracer compounds in the soil gas samples employing an aboveground sampling apparatus (20). The aboveground sampling apparatus does not include any device that penetrates the soil surface of ma n- made structures imposed upon the soil surface. Rather, the aboveground sampling apparatus evacuates soil gas samples through the soils surface or through man-made structures imposed upon the soil surface, such as asphalt o r concrete, and passes the soil gas sample through an adsorbent bed (30) containing adsorbent material specific for the distinctive chemical tracer compounds.
