ABSTRACT:
A method and system for detecting environmental contamination, such as subsurface contamination, include a test probe located in a medium. The probe is adapted to collect a fluid sample from the medium for determining the presence of a contaminant having a vapor pressure. Pneumatic communication lines extend from a test point and connect to the probe. A detector/analyzer is connected to the distal end of the communication lines of the probe. While connected, a fluid sample is taken into the probe and transported in the pneumatic communication lines by a carrier gas to the detector/analyzer for analysis of the contaminant. The general principle is applicable for contaminant detection and/or analysis in soil masses, liquid masses and gases.
