Abstract : The objectives of this project were to demonstrate the following: (1) that in situ biological perchlorate treatment is feasible in the field using electron donor addition; (2) that perchlorate can be treated to 4 micrograms per liter; (3) that perchlorate can be treated in a drinking water aquifer without mobilizing significant quantities of Fe and Mn or bringing oxidation reduction potentials (ORP) to very low levels; (4) that the zone of influence and efficiency of the HFTW system are sufficient to make the technology a viable, cost-effective option at many sites; (4) that biofouling can be effectively controlled by measures that are easily implemented and (5) that co-contaminants, including nitrate and trichloroethene (TCE), can be treated using the same HFTW technology. As with any pilot-scale technology demonstration, a main objective of this field project was to collect and document information that is relevant to site managers and regulators who are responsible for choosing and implementing technologies.
