Selecting Exposure Routes and Contaminants of Concern by Risk-Based Screening (1993)
This guidance is intended to identify and focus on dominant contaminants of concern and exposure routes at the earliest feasible point in the baseline risk assessment. Use of these methods will decrease effort and time spent assessing risk, without loss of protectiveness.
EPA 903-R-93-001 Army Risk Assessment Modeling System
The U.S. Department of Defense and the Army conduct risk assessments to determine safe levels and cleanup target levels for military relevant compounds (MRCs) and to evaluate remediation alternatives to provide the most cost-effective approach to reach target levels. As part of the Army's Installation Restoration Research Program (IRRP), the U.S. Army Engineer Research and Development Center (ERDC) is developing a computer-based, modeling- and database-driven analysis system for estimating human and ecological health impacts and risks associated with MRCs. The Army Risk Assessment Modeling System (ARAMS) is based on a widely accepted risk paradigm that integrates exposure and effects assessments to characterize risk.
