Disclosed are methods, devices and apparatus for bioremediation of mixed
waste aquifers, based on a synergistic combination of reductive treatment
using zero-valent iron and anaerobic biotransformations. Also disclosed
are methods for in situ and ex situ remediation of groundwater and
wastewater via these iron-bacterial compositions in a variety of devices
including batch reactors, permeable and semipermeable reactive barriers,
flow-through reactors, fluidized bed reactors, and sediment tanks.
