Soil Gas and Soil Vapor Sampling

Soil gas or Soil vapor sampling can be achieved in a wide variety of locations under a wide variety of conditions. Sub-slab installations can be carried out by hand for shallow depths or with our limited access machines for deeper depths.

Soil Vapor Implants installed by GeoTek Hawaii are a high quality stainless steel implant. Usually installed for long term monitoring or for more controlled sample intervals.

Advantages

•	A variety of lengths can be used to tailor the implants to site conditions.
•	A variety of tubing sizes and connections are offered for simple integration to sampling apparatus.
•	Constructed of 100% stainless steel and decontamination can be confirmed prior to installation.
•	Small diameters permit ‘nesting’ of multiple implants into a single bore hole.
•	Leak detection helium shrouds are easily configured to encompass the sampling point.

Vapor Pins™
For shallow sub-slab soil gas samples the Vapor Pin™ may be the best fit. A patented sampling port is installed into the slab with powered and manual tools.

Advantages

•	Quick installation time permits high volumes of sampling locations in a single day
•	Slab impact and work area influence is very minimal
•	Disposable seal minimizes any additional installation materials
•	Creates a very small sampling port reducing the required volume of helium

Post Run Tubing (PRT)
Post Run Tubing (PRT) is a very efficient tool when it comes to soil vapor investigations. A tool string is advanced to the target depth. Once the sampling interval is exposed, an adapter is connected to a length of Teflon tubing and connected at the bottom of the tool string.

Advantages

•	Very quick and easy to manage multiple sampling points and intervals
•	Single piece tubing minimizes any leakage points ensuring sample integrity
•	Sample collection system can be leak checked easily.
•	Adaptability to virtually any vapor collection apparatus.
