Vapor Intrusion Testing

Mountain Research provides complete vapor intrusion into buildings (VIB) services. VIB potential can be assessed using indoor air quality (IAQ) or, as preferred by Pennsylvania regulators, using soil gas sampling.

Samples are collected by Mountain Research’s experienced and properly trained personnel using gas canisters. For soil gas, sampling probes are installed using our Geoprobe® rigs.

Analytical results are evaluated in accordance with relevant regulations, and, as necessary, computer modeling of results is conducted to evaluate potential risks when concentrations exceed media specific concentrations. When needed, Mountain Research can provide design and mitigation of vapor intrusion issues.


Our goal is to achieve total customer satisfaction by performing the highest quality environmental, engineering and laboratory services, completed on time and at a fair price.
