Soil vapor sampling is a process used to collect and analyze gases and vapors that are present in the soil beneath the Earth's surface. This technique is often employed to assess and monitor soil and groundwater contamination, especially in areas where hazardous substances have been released or spilled. Soil vapor sampling involves drilling holes into the ground and inserting specialized probes or devices to collect gas samples from various depths. The collected samples are then analyzed to determine the presence and concentration of volatile organic compounds, gases, or contaminants, which can help environmental professionals assess the extent of soil or groundwater pollution and plan remediation efforts. This is a collection of all the products typically used in vapor sampling and testing.
