Vapor Intrusion

Vapor Intrusion occurs when vapors from volatile hazardous substances in contaminated soil or groundwater migrate into the indoor air of an overlying home or building. When air quality may be compromised due to vapor intrusion, you need a specialist to assess the contamination levels, whether there are significant health risks, and the viable methods of remediation. St.Germain Collins has the necessary technical proficiency and an experienced team ready to guide you through the special challenges presented by this field and the developing science surrounding it.
