This toolkit replaces, combines, and updates three previous ITRC vapor intrusion documents to create a scientifically based, consensus approach to explain concepts and best practices regarding vapor intrusion.

A training site with interactive workshops and tools to help users apply petroleum guidance to build site models, assess risk, and manage sites.

Provides tools and recommendations for evaluating risks, assessing human health and ecological impacts, and making cleanup decisions at petroleum-contaminated sites.

Provides an eight-step process with checklists for the effective assessment and management of vapor intrusion at sites contaminated with petroleum hydrocarbons.

Evaluation of state practices for establishing and implementing closure criteria for bioventing, vapor extraction, and natural attenuation of petroleum hydrocarbons and chlorinated solvents.

An outline and protocol for the general class of in situ bioremediation technologies. Includes a detailed literature review of technology-specific protocols for natural attenuation and bioventing of petroleum hydrocarbons.

An evaluation of SCAPS-LIF technology and it’s ability to provide real-time in-situ detection of total petroleum hydrocarbon contamination both above and below the water table.
