Framework for Investigating Asbestos-Contaminated Hazardous Waste Sites (PDF) (71 pp, 849KB) OSWER Directive 9200.0-68, September 2008. This document presents a recommended framework for investigating and characterizing the potential for human exposure from asbestos contamination in outdoor soil and indoor dust at Superfund removal and remedial sites. This framework discusses an empirical approach and strategies that are based on the best available science and recommends common industrial hygiene methods for characterizing exposure and risk from asbestos.

Clarifying Cleanup Goals and Identification of New Assessment Tools for Evaluating Asbestos at Superfund Cleanups (Michael B. Cook – August 10, 2004) OSWER Directive 9345.4-05 (PDF) (4pp, 120 KB).
