Vapor Intrusion

Volatile organic compounds (VOCs) are present in soil and groundwater at virtually every industrial and commercial facility that ever stored, used, or disposed of fuels or solvents. The potential for VOCs to migrate upward into a building is known as “vapor intrusion” and is now among the highest priorities of EPA and state agencies.

Cox-Colvin has successfully completed numerous vapor intrusion assessment, source area prospecting, and vapor mitigation projects throughout the country. Our innovative approaches for investigating subsurface VOCs enable us to collect large soil-gas data sets with unprecedented speed and accuracy allowing us to better understand site conditions. Using this information we are able to locate contamination sources quickly and efficiently, and target remediation and mitigation efforts, saving our clients time and money. This experience led to the development of our patented VAPOR PIN®, which is rapidly becoming the industry standard in sub-slab soil-gas sampling.

If vapor intrusion is a potential issue, either on-site or off-site, Cox-Colvin has the expertise to complete accurate and timely assessments; remediate vapor sources through soil removal or treatment; or reduce the effects of vapor intrusion through the design and installation of vapor mitigation systems.
