Abstract : This report summarizes the findings of research carried out at Arizona State University (ASU) in parallel with a field pilot study led by CDM Smith in cooperation with APTwater and reported in its own final report. The objective of the overall project was biological treatment of a groundwater contaminated with two oxidized contaminants: nitrate (NO3-) and perchlorate (ClO4-). Dissolved oxygen (O2) and sulfate (SO42-) are oxidized compounds that also were present. The treatment goal was to use the H2-based Membrane Biofilm Reactor (MBfR) to achieve microbial reduction of NO3- and ClO4- into innocuous substances (N2, H2O, and Cl-), while not promoting SO42- reduction to sulfide.
