Alternatives For In Situ Bioremediation Of Perchlorate
Perchlorate can be reduced to the innocuous anion chloride under slightly reducing conditions by several microorganisms that are apparently ubiquitous in soils and groundwaters (Coates et al., 1999; Logan, 2001). This reduction can happen naturally, but stimulation of the activity of indigenous perchlorate reducers by addition of an electron donor to the subsurface environment is often needed because natural attenuation alone may not be sufficient to ensure environmental protection. The deliberate enhancement of natural biodegradation (bioremediation) has proven to be a successful technology for treating perchlorate contaminated soils and groundwaters (Xu et al., 2003). Currently there are few other mechanisms available for cost-effectively treating perchlorate in situ.
