11.1 Introduction

Remediation of perchlorate in groundwater by monitored natural attenuation (MNA), phytoremediation to treat perchlorate in soils and groundwaters, and in situ bioremediation of perchlorate sources in the vadose zone, are three promising innovative approaches. These approaches have solid technical underpinnings, but there are uncertainties that need to be addressed to allow them to become as mature and as widely applied as the technologies described in the preceding chapters.

As shown in earlier chapters, perchlorate degraders are widely distributed and are easily stimulated by the addition of electron donors to degrade perchlorate sequentially via chlorate (ClO3) and chlorite (ClO2) to chloride (Cl) (Coates et al., 1999; van Ginkel et al., 1996; Herman and Frankenberger, 1999; Logan, 2001; Logan et al., 2001a; Losi et al., 2002; Urbansky, 1998). The more mature technologies discussed earlier involve the addition of electron donors into contaminated groundwater to...
