Assemblies for Use in Evaluating Subsurface Contamination, and Related Methods

A method is provided for determining the presence and/or concentration of at least one contaminant in a subsurface at a test site. The method generally includes inserting a sampling assembly into at least one tree at the test site, processing at least part of the sampling assembly to determine if a contaminant is present in the at least one tree, and then correlating the presence and/or concentration of the contaminant in the at least one tree to presence and/or concentration of the contaminant in the subsurface. The sampling assembly is operable to sorb at least one contaminant located within the at least one tree to at least part of the sampling assembly. The sampling assembly may include a solid phase microextraction (SPME) sampling assembly having a SPME sampling device and a support configured to help position the SPME sampling device within a tree for sampling operation.
