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’s breathing space is known as “vapor intrusion” and is now among EPA’s highest priorities. Soil-gas sampling is a vital component of any vapor intrusion investigation.

Vapor intrusion investigations are typically performed in accordance with US EPA’s OSWER Final Guidance for Assessing and Mitigating the Vapor Intrusion Pathway (April 2013, external draft review), and with applicable state or local guidance.

Cox-Colvin has successfully completed numerous vapor intrusion assessments, source area prospecting and vapor mitigation projects throughout the Midwest. Our innovative approaches for investigating subsurface VOCs enable us to collect large soil-gas datasets with unprecedented speed and accuracy to better understand site conditions. Using this information, we are able to locate and eliminate contamination sources quickly and efficiently, saving our clients time and money.

Our vapor intrusion services include:

  • Vapor intrusion assessment
  • Soil gas sampling
  • Indoor air sampling
  • Johnson & Ettinger modeling
  • Vapor intrusion mitigation
  • Source area prospecting

This experience led to the development of our patented VAPOR PIN®, which is rapidly becoming the worldwide 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.
