Current United States aircraft are equipped with a multitude of protective coatings on the interior and exterior of the vehicle, ultimately enhancing their ability to ensure a safe and effective mission. Aircraft, over the course of their lifetime, will experience impact, corrosion, weathering, and microbial damage to its defensive structures, rendering it vulnerable to attacks. Damaged coatings are then repaired on the aircraft once detected in inspection or replaced in accordance to the lifecycle of the material on the aircraft. However potentially harmful threats such as bacteria are not considered by the Air Force to be dangerous. Therefore, the purpose …

Chlorinated aliphatic hydrocarbons (CAHs) are often found as groundwater contaminants because of past industrial activities and disposal practices. CAHs pose a threat to human health and thus, create a need to find both natural and engineered processes that can remove these chlorinated compounds from the environment. Natural attenuation by oxidative biodegradation is especially important because it can allow for mineralization to carbon dioxide, a nontoxic end-product. The goal of this research was to evaluate the potential oxidative biodegradation of CAHs by microorganisms that are naturally associated with wetland plant roots. The research was divided into field work and laboratory batch …
