Srivatsan Mohana Rangan, Graduate Student, Biodesign Swette Center for Environmental Biotechnology, presents:

The risks and disadvantages in utilizing zero-valent iron (ZVI) for enhancing bioremediation of trichloroethene- and perchlorate-contaminated soil and groundwater are not completely understood. Using semibatch microcosms, Rangan and colleagues studied conditions representing both injection zone and downstream zone when ZVI and bioremediation are simultaneously applied in the site. The results point out that ZVI itself and Fe(II) – that results from ZVI reactions – inhibited TCE and perchlorate biological reduction, despite providing anoxic conditions.
