Abstract
A new method of treating water to remove perchlorate contaminant is disclosed. Water is fed through a filter bed containing perchlorate-reducing microorganisms. The microorganisms reduce the perchlorate, thereby decontaminating the water. An oxidizable substrate serves as an electron donor to the microorganisms. The invention results in safe to undetectable levels of perchlorate in the treated water.
