Department of Defense Vapor Intrusion Handbook


Book Description

This handbook was developed by the Tri-Service Environmental Risk Assessment Work Group (TSERAWG) to serve as a resource for remedial project managers (RPMs) who may need to investigate the vapor intrusion pathway at Department of Defense (DoD) sites. The Tri-Services of the DoD include the Departments of the Air Force, Army, and Navy, with the Department of the Navy (DON) including both the Navy and the Marine Corps. This handbook was developed to support RPMs working on both active and closed Air Force, Army, Navy, and Marine Corps bases, as well as Formerly Used Defense Sites (FUDS). The handbook is intended to provide a general framework for conducting vapor intrusion investigations under the Defense Environmental Restoration Program (DERP). Both residential and occupational exposure scenarios are discussed since both groups can be affected by vapor intrusion.







Contaminants in the Subsurface


Book Description

At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.
