ABSTRACT:
A soil sampler for insertion into a pilot hole in the earth to extract contaminants in a vapor state. The sampler has an axially forward projection and an axially rearward projection that define a volume together with the body of the sampler and the wall of the pilot hole. Steam passes into the sampler so as to heat a portion of the sampler near the volume so as to volatize the contaminants. The sampler exerts a vacuum on the volume to extract the gaseous contaminants into an analyzer assembly.
