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.

This guidance document provides a comprehensive defensible framework for establishing and using soil background in risk assessments.

This updated web-based document assist’s site managers in developing an integrated DNAPL site management strategy.

The web-based guidance designed to help state regulators and other practitioners understand, evaluate, and select advanced site characterization tools (ASCTs) to support site conceptual site model and remedial strategy development and refinement.

The ITRC TPH Risk Evaluation at Petroleum-Contaminated Sites guidance builds on long-standing and current research, and presents the current science for evaluating TPH risk at petroleum-contaminated sites.

Used for any LNAPL site regardless of size and site use and provides a systematic framework: it aids in the understanding, cleanup, and management of LNAPL at thousands of sites with varied uses and complexities

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