Perchlorate is a chemically stable anion which was used as an oxidizer in rocket propellant and explosives throughout the 1950’s and 1960’s. While natural sources of perchlorate exist, perchlorate in the environment is primarily a result of contamination from anthropogenic processes. Perchlorate contamination has now been identified in at least 45 states and is hazard to human health due to perchlorate’s ability to interfere with uptake of iodine in the thyroid gland. One of the most common and cost effective treatment methods for perchlorate remediation is biological reduction—utilizing bacteria to enzymatically reduce perchlorate into chloride and oxygen.

Remediation of contaminated groundwater is becoming increasingly more
important as much of the U.S. population relies on groundwater for their drinking water.
Contaminates such as Chromium, common pollutant at industrial waste sites, and
Hexavalent chromium which is toxic to humans, animals, and plants are major
concerns. Chlorate, another contaminate of concern, has been widely detected in
ground and surface water in the United States and even locally in Henderson Nevada at
the Nevada Environmental Response Trust (NERT) sites. To assist in mitigating this
issue, this research focuses on the removal of high levels of hexavalent chromium (ppm
range) (Cr(VI)) and …
