The Passive Sampling Update Guidance Document combines the previous ITRC Passive Sampling documents (DSP-1, DSP-3. DSP-4, DSP-5) along with updates to the technologies into one comprehensive document that evaluates 24 passive sampling technologies.

Provides more details regarding the design, construction, modeling, and long-term monitoring and maintenance of the chemical isolation.

Provides an understanding of adaptive management for optimization, presents a technical framework for P&T site optimization, and includes interactive checklists, detailed evaluation guidance, and supporting case studies of project implementation.

This training site builds upon the information presented in three ITRC Guidance Documents: Light Non-Aqueous Phase Liquid (LNAPL), Petroleum Vapor Intrusion (PVI), and Total Petroleum Hydrocarbon (TPH) Risk Evaluation.

Provides resources for regulators, stakeholders, consultants, and responsible parties to help integrate sustainability and resilience practices into remediation projects.

Technical Resources for Vapor Intrusion Mitigation (VIM) is designed to aid state regulators in understanding various mitigation strategies, how they are installed and fundamentally work, and what factors to consider as part of the review process.

Builds upon the 2012 version (ISM-1) and reflects advancements in technology in the ensuing eight years.

An updated ITRC guidance (ISM-2) was developed and posted in the fall of 2020. The ISM-2 Update Team clarified inappropriate or inconsistent information in ISM-1 is as seen in the attached statement.  Please review this document before downloading the ISM-1 PDF.

ITRC has developed this resource to summarize the latest science and emerging technologies for 1,4-Dioxane.

Comprehensive guidance on common in situ remediation challenges, including remedial design, implementation, and monitoring.
