This guidance document provides readers with practical steps to manage the remediation process at complex sites where remediation progress is uncertain and remediation is not anticipated to achieve closure or even long-term management within a reasonable time frame.

This guidance focuses on long-term contaminant management using institutional controls (ICs).

The Geospatial Analysis for Optimization at Environmental Sites (GRO-1) web-based guidance is designed to help practitioners better apply geospatial analyses in environmental projects.

This document explains the process of geophysical classification, describes its benefits and limitations, and most importantly discusses the information and data needed by regulators to monitor and evaluate the use of the technology.

This ITRC resource guides environmental professionals through selecting and applying tools for integrated site characterization and remediation at DNAPL-contaminated sites.

This document assists effective decision-making among state, local, and federal project managers and decision makers tasked with developing or reviewing risk assessments for contaminated sites using site-specific approaches, scenarios, and parameters.

This ITRC petroleum vapor intrusion (PVI) guidance document provides an 8-step process for the effective assessment and management of vapor intrusion at sites contaminated with petroleum hydrocarbons. The guidance presents a method of screening petroleum-contaminated sites for potential vapor intrusion and tools and strategies that offer the most efficient means of evaluating the vapor intrusion pathway at these sites.  Two checklists are also included as attachments to use in conjunction with the eight-step process to organize and document decisions; one for a single site and one for multiple sites.

The objective of this guidance document is to assist decision-makers in identifying which contaminated sediment remedial technology is most favorable for a site based upon an evaluation of site-specific physical, sediment, contaminant, and land and waterway use characteristics.

The Groundwater Statistics and Monitoring Compliance (GSMC) web-based guidance helps users without statistical expertise understand groundwater cleanup techniques and apply them throughout all project stages: release detection, site characterization, remediation, monitoring, and closure.

This web based guidance document provides a format that is easy to navigate through an in-depth analysis and overview of Biochemical Reactors (BCRs) for mining influenced water (MIW).
