Additional information

Perchlorate's low reactivity at ambient temperatures and dilute concentrations might imply that direct chemical transformation of perchlorate in the environment-through participation in oxidation-reduction reactions without the influence of microorganisms-is unlikely. However, a growing number of field and labratory studies have shown that perchlorate can be biologically transformed. Bacteria capable of perchlorate degradation are widely distributed in nature and significant numbers of perchlorate reducing bacteria have been found in samples collected from both pristine and contaminated environments.
