In situ Bioremediation of Perchlorate
Abstract
The objective of this project is to develop a biological treatment technology for in situ remediation of perchlorate in subsurface environments. The development of an effective technology for perchlorate remediation requires a fundamental understanding of the conditions that limit biological perchlorate reduction in groundwater and the most effective means to overcome such limitations. This research effort is designed to provide this fundamental understanding. We hypothesize that four key factors may be contributing to the persistence of perchlorate at various subsurface sites. These key factors and our approach to their evaluation in the research paper are as follows: (1) Absence of an appropriate substrate (electron donor) for growth of indigenous perchlorate degrading bacteria; (2) Presence of alternative electron acceptors for bacterial respiration, including 02, NO3, and NO2 in groundwater; (3) Lack of an indigenous population of bacteria capable of perchlorate reduction; and (4) Unfavorable environmental conditions for activity of indigenous perchlorate degraders.
