For vapor intrusion (VI) purposes, volatile organic compounds (VOCs) are often placed into one of two groups – chlorinated VOCs(CVOCs) or petroleum hydrocarbons (PHCs). Because CVOCs and PHCs behave differently in the subsurface, and because their use and consumption are dominated by different industries, CVOCs and PHCs are often regulated differently.
Vapor Pin® is a founding member of AVIP. The purpose of AVIP is to build a community of professionals, dedicated to advancing the industry and providing a forum for the exchange of knowledge and science related to Vapor Intrusion (VI); as well as establishing a central resource for technology, guidance, standards, credentialing and best practices for both those in the industry and those seeking VI related services.
