Soil Gas Sampling
Soil gas sampling is a service used to assess the presence and type of contaminants in the subsurface soil. It involves collecting samples of the gas trapped in the pore spaces between soil particles. This can be helpful for a variety of reasons, such as:
Identifying contamination:
Soil gas sampling can be used to identify the presence of volatile organic compounds (VOCs) such as gasoline, solvents, and industrial chemicals.
Optimizing well placement:
In the initial stages of a site investigation, soil gas sampling can help identify areas where further investigation, like drilling wells, is needed.
Assessing vapor intrusion:
Soil gas testing can help assess the risk of vapor intrusion, which is the migration of contaminants from the soil into buildings.
There are two main types of soil gas sampling methods
Soil gas sampling is a relatively quick and cost-effective way to assess subsurface contamination. It can be a valuable tool for environmental engineers, property developers, and anyone else who needs to know about the quality of the soil on a particular site.
Active sampling:
This method involves using a probe to extract soil gas from the ground. The gas is then collected in a Tedlar bag or canister or analyzed on-site using a mobile laboratory.
Passive sampling:
This method involves placing a sorbent material (a material that absorbs chemicals) in the soil for a period of time. The sorbent material is then collected and analyzed in a laboratory.
