ITRC publishes documents that broaden and deepen technical knowledge and expedite quality decision-making when faced with environmental challenges. ITRC has produced documents ranging from technical overviews and case studies of innovative remediation technologies to technical and regulatory guidance documents for applying cleanup technologies. ITRC documents are written and reviewed by teams of environmental professionals, including state and federal environmental regulators, federal agency representatives, industry experts, community stakeholders, and academia. With private and public sector members from all 50 states, the District of Columbia, and Puerto Rico, ITRC documents truly provide a national perspective.

Bioavailability of Contaminants in Soil provides guidance on how to integrate bioavailability information into the human health risk assessment to improve the decision-making process.
Understanding the complexity of subsurface geologic conditions is paramount in improving DNAPL site characterization. This guidance document reviews the current knowledge of DNAPLs and their subsurface contaminant behavior. Using an integrated site characterization (ISC) approach, under which data of adequate resolution are collected to fully characterize a site, this new guidance describes how data can be aligned on contaminant distribution with site geologic heterogeneity and groundwater flow conditions at a spatial resolution appropriate to the site-specific remedial objectives. Thus, with the current understanding of subsurface contaminant behavior, both existing and new tools and techniques can be used to measure physical, chemical, and hydrologic subsurface parameters to better characterize the subsurface.
Contaminated fractured rock sites have often been considered too complex to be remediated, so site managers often default to simply containing the contamination. With the new strategies and technologies presented here, fractured bedrock challenges that may have prevented site remediation in the past are now surmountable.
The Geospatial Analysis for Optimization at Environmental Sites document provides information about using geospatial methods in all project life cycle stages: release detection, site characterization, remediation, monitoring and closure. The document provides a needed resource to state regulators, practitioners and stakeholders about using geospatial analysis to support decisions on optimization.

At many sites of environmental contamination, even with active remediation, Institutional Controls (ICs) are used with the intention to minimize the potential for human health exposures to hazardous substances or protect the integrity of a remedy by limiting land or resource use (controlling how the property is used). Since more sites and more contaminants are being managed through the use of ICs ITRC has developed a guidance on the Long Term Management of Contaminant Using Institutional Controls.
The LNAPLs (Light Non-Aqueous Phase Liquids) documents help users identify appropriate LNAPL remedial goals through the development of a site-specific LNAPL conceptual site model (LCSM), provides tools to select LNAPL remedial technologies that will best achieve the LNAPL remedial goals, and provides a framework to evaluate the implemented technologies progress toward a technology specific endpoint.
Provides a framework for assessing the performance of new or innovative methane detection technologies and discusses regulatory barriers and opportunities for the use and adoption of such technologies.
The PFAS documents provide technical resources for addressing environmental releases of Per- and Polyfluoroalkyl Substances (PFAS). They include fact sheets to summarize the latest science and emerging technologies for PFAS. Fact sheet users should visit the PFAS Fact Sheets page to access the current version of the files.
At complex sites, remediation progress is uncertain and remediation is not anticipated to achieve closure or even long-term management within a reasonable time frame. Both technical and nontechnical challenges can impede remediation. The Remediation Management of Complex Sites web-based document provides readers with practical steps to manage the remediation process at complex sites, despite this uncertainty. A holistic process for remediation management, termed “adaptive site management” is recommended. Using this guidance can improve decision making and remediation management. The guidance is intended to benefit a variety of site decision makers, including regulators, responsible parties and their consultants, and public and tribal stakeholders.

This guidance is intended to provide a nation-wide perspective on the challenges facing the stormwater industry in evaluating the performance of post-construction Best Management Practices (BMPs) throughout a project lifecycle. The guidance describes historic, existing and developing post-construction BMP performance verification and certification programs, and captures existing program data in a new BMP screening tool to assist users during the design of a project.
Presents the current science for evaluating TPH risk at petroleum-contaminated sites to assist decision makers in developing and implementing a technically defensible approach.
