Examination of Risk-Based Screening Values and Approaches of Selected States – White Paper
Provides information on the different methods used by regulatory agencies to develop and apply screening values for evaluating contaminated media. The document highlights the need for transparency of methodologies to develop screening values and their application at contaminated sites.
Electronic Risk Resource Sheet
Contains links that connect to databases, tools, and topics that address risk assessment and is a valuable tool to anyone interested in the subject of risk assessment. This resource is a dynamic resource that will be updated periodically.
Adaptive Risk Assessment Modeling System (ARAMS)
A computer-based, modeling- and database-driven analysis system for estimating human and ecological health impacts and risks associated with potential contaminants of concern. ARAMS is based on a widely accepted risk paradigm that integrates exposure and effects assessments to characterize risk. The team is currently working on a project in cooperation with the USACE that focuses on the review of the ARAMS tool and the development of a Technology and Transfer Workshop that will be held in 2008.
Risk Assessment and Risk Management: Determination and Application of Risk-Based Values
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. The second module focuses on the process by which risk-based levels are derived in different states. 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.
The Risk team has been regularly participating and presenting at the International Society of Risk Analysis (SRA) Annual Meetings (view a few of the presentations below) and at the Midwestern Risk Assessment Forum. The team has also coordinated with SRA in co-sponsoring workshops on Probabilistic Risk Assessments. The Risk Team has worked closely with all federal partners including: EPA’s Annual Science Forum , DOE’s Risk-based End State development and DOD’s work on ARAMS model development. With all these efforts, the team is reaching out to various audiences in States, local, academia and Industry.
