It is less than 7 years since perchlorate, a predominantly man-made toxic anion, was first
identified as a significant water contaminant throughout the United States. Owing to its …

Energetic materials comprise both explosives and propellants. When released to the
biosphere, energetics are xenobiotic contaminants which pose toxic hazards to ecosystems …

In the United States anthropogenic activities are mainly responsible for the wide spread
perchlorate contamination of drinking water, surface water, groundwater, and soil. Even at …

Molecular-scale surface roughness and charge heterogeneity have been hypothesized as
factors that can affect the deposition rates of colloids during their transport in porous media …

As part of a study to elucidate the environmental parameters that control microbial
perchlorate respiration, we investigated the reduction of perchlorate by the dissimilatory …

Perchlorate (ClO4-) release into the environment has occurred primarily in association with
its manufacture and use in solid rocket propellant. When released into groundwater …

The perchlorate anion (ClO4–) has been found in potentially harmful concentrations in
numerous water sources. Because perchlorate is not removed by conventional water …

Aerobic granular sludge is attractive for high-rate biological wastewater treatment. Biomass
wash-out conditions stimulate the formation of aerobic granules. Deteriorated performances …

The biological degradation of nitrate and perchlorate was investigated in an ion exchange
membrane bioreactor (IEMB) using a mixed anoxic microbial culture and ethanol as the …

The biological degradation of perchlorate was examined using a laboratory-scale,
autotrophic, packed-bed biofilm reactor. The reactor was operated in unsaturated-flow mode …
