Abstract
Bioremediation of perchlorate-contaminated groundwa-
ter can occur via bacterial reduction of perchlorate to
chloride. Although perchlorate reduction has been
demonstrated in bacterial pure cultures, little is known
about the efficacy of using perchlorate-reducing bacteria
as inoculants for bioremediation in the field. A pilot-
scale, fixed-bed bioreactor containing plastic support
medium was used to treat perchlorate-contaminated
