Abstract:

A number of improvements and advances for the enhanced in situ bioremediation of chlorinated solvents have been made since the Tri-Services Principles and Practices of Enhanced Anaerobic Bioremediation of Chlorinated Solvents guidance document was released in August 2004 Air Force Center for Engineering and the Environment AFCEE et al., 2004. Numerous demonstration and full-scale applications have been completed, yet challenges to successful implementation of the technology remain Simpkin and Norris, 2010 Suthersan and Payne, 2003. In particular, there remains some uncertainty and a lack of guidance for determining appropriate substrate loading rates and delivery methods based on site-specific conditions. This addendum to the 2004 Principles and Practices document provides a description of a demonstration study conducted to evaluate substrate loading rates, including a summary of limiting factors and challenges to applying enhanced in situ bioremediation. This addendum also summarizes advances made in the field of enhanced in situ bioremediation of chlorinated solvents over the last six years and provides resources and references that may be used to identify and mitigate the limiting factors and challenges that practitioners face when applying the technology.
