The Risk training courses address methods used by regulatory agencies to use risk assessment and risk-related practices in managing contaminated sites.

Determination and Application of Risk-Based Values

Assessment of human health risks posed by exposure to hazardous substances is a vital component to the process of remediation of contaminated sites. Risk-based screening values are developed and used in both planning and conducting site remediation. This training course is designed for site managers and others involved in making remedial decisions to help them better understand the risk assessment / risk management process. This training course describes the development and application of risk-based screening values. The first module provides a review of key risk assessment concepts related to risk management. It also introduces the Electronic Risk Resource Sheet developed by the ITRC Risk Assessment Resources team. The second module focuses on the process by which risk-based levels are derived in different states. This module introduces the document, Examination of Risk-Based Screening Values and Approaches of Selected States (RISK-1, 2005), developed by the ITRC Risk Assessment Resources team. The third module examines the application of risk assessment to remediation operations in two case studies providing examples of how risk assessment has actually been implemented, based upon research and case studies conducted by the ITRC Risk Assessment Resources team. This training course describes a number of the reasons behind variations in risk-based screening values and their use in risk management. Overall, the training course enhances the transparency and understanding of risk assessment and its use in remediation.

Issues and Options in Human Health Risk Assessment - A Resource When Alternatives to Default Parameters and Scenarios are Proposed

Many state and local regulatory agencies responsible for the cleanup of chemicals released to the environment have adopted regulations, guidance and policies that define default approaches, scenarios, and parameters as a starting point for risk assessment and the development of risk-based screening values. Regulatory project managers and decision makers, however, may not have specific guidance when alternative approaches, scenarios, and parameters are proposed for site-specific risk assessments, and are faced with difficult technical issues when evaluating these site-specific risk assessments. This ITRC web-based document is a resource for project managers and decision makers to help evaluate alternatives to risk assessment default approaches, scenarios and parameters.

ITRC's Decision Making at Contaminated Sites: Issues and Options in Human Health Risk Assessment (RISK-3, 2015) guidance document is different from existing ITRC Risk Assessment guidance and other state and federal resources because it identifies commonly encountered issues and discusses options in risk assessment when applying site-specific alternatives to defaults. In addition, the document includes links to resources and tools that provide even more detailed information on the specific issues and potential options. The ITRC Risk Assessment Team believes that state regulatory agencies and other organizations can use the RISK-3 document as a resource or reference to supplement their existing guidance. Community members and other stakeholders also may find this document helpful in understanding and using risk assessment information.

After participating in this ITRC training course, the learner will be able to apply ITRC's Decision Making at Contaminated Sites: Issues and Options in Human Health Risk (RISK-3, 2015) document when developing or reviewing site-specific risk assessments by:

ITRC offers additional documents and training on risk management. ITRC's Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008) and associated Internet-based training archive highlight variation of risk-based site management and describes how to improve the use of risk assessment for making better risk management decisions. ITRC's Examination of Risk-Based Screening Values and Approaches of Selected States (RISK-1, 2005) and associated Internet-based training archive focus on the process by which risk-based levels are derived in different states.

Use of Risk Assessment in Management of Contaminated Sites

The ITRC Risk Assessment Resources team developed a document titled Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008). This Internet-based training is taken from the RISK-2 document and highlights variation of risk-based site management and how to improve the use of risk assessment for making better risk management decisions. This training course looks at how various risk-based approaches and criteria are applied in various states and programs throughout the processes of screening, characterization, and management of contaminated sites.

The document and training course are intended for risk assessors and project managers involved with the characterization, remediation, and/or re-use of sites. Together they provide a valuable tool for federal and state regulatory agencies to demonstrate how site data collection, risk assessment, and risk management may be better integrated. This training course explains:

This course builds on the Team's previous work identifying variation in the development of risk-based numerical criteria, specifically soil screening levels. A prerequisite to this training course is the Risk Team's previous Internet-based training (archive is available from http://www.clu-in.org/conf/itrc/risk_040810/) based on ITRC's Risk Assessment and Risk Management: Determination of Risk-Based Values (RISK-1, 2005). The Electronic Risk Resource Sheet published by the ITRC Risk Team is recommended as an excellent resource for supplemental materials related to risk assessment and risk management.
