Anaerobic Dechlorination of PCE to Ethene, Modeling, and Characterization of the Factors Affecting the Transformation Rates

Creator:: Albers, Delancy R.
Abstract:: Tetrachlorethene (PCE) and trichloroethene (TCE) were common solvents used in the 1970’s that are now frequently observed groundwater contaminants. One method of remediating these contaminants is in-situ bioremediation that uses a dechlorinating microbial population. The microbial population performs the sequential reductive dechlorination of PCE and TCE to cis-1,2-dichloroethene (c-DCE), vinyl...

Solar Thermal Energy System for Renewable Desalination

Creator:: McLaughlin, Ryan P.
Abstract:: Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....

Anaerobic Dehalogenation of Trichloroethene by Encapsulated Dehalococcoides mccartyi

Creator:: Lukens, Eileen P.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) like trichloroethene (TCE) were mostly used to replace drying cleaning fluids which contained hydrocarbons like benzene, and were highly flammable. Through improper disposal, storage, and spills, TCE and its downstream products, like cis-dichloroethene (cDCE) and vinyl chloride (VC), leached into groundwater and threaten human and environmental...

Encapsulation of Rhodococcus rhodochrous ATCC 21198 in gellan gum at high densities and with a slow-release substrate for the in-situ bioremediation of contaminant mixtures from groundwater

Creator:: Williams, Gillian R.
Abstract:: As access to potable water grows scarce, there is an increasing reliance on alternative drinking water sources, namely groundwater (WHO, 2018). Chlorinated solvents, such as 1,1,1-trichloroethane (TCA) and 1,2-cis-Dichloroethene (cisDCE) are some of the most ubiquitous groundwater contaminants spread throughout the US. 1,4-dioxane (1,4D) was used primarily in the late...

Removing Chemical Oxygen Demand (COD) Assay Interference from Landfill Leachate Samples Treated with Fenton's Reagents

Creator:: Palmer, Matthew
Abstract:: Incompatibility between Fenton’s Reagents and a potassium dichromate COD test provides interference that prevent accurate measurements of the concentration of organics from oxidized samples. Several treatment options were tested to remove this interference. Oxidation of reagents was eliminated as a potential method for removal of interference due to sample contamination....

The Stability, Toxicity, and Reactivity of Zero Valent Iron Nanoparticles

Creator:: Bulovsky, Hannah G.
Abstract:: Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...

Transient Electron Donor Concentration Experiments for the Determination of Dehalogenation Rate and Kinetic Parameter Shifts in an Anaerobic Microbial Culture

Creator:: Green, Jennifer K.
Abstract:: Trichloroethene (TCE) is a common groundwater contaminant. Bioremediation, or the enhancement of natural microbial processes for the transformation of toxic compounds in soil and groundwater, is an effective solution to this widespread problem. The organisms that transform TCE in the subsurface are sensitive to environmental conditions, especially to the presence...

Kinetic analysis of the aerobic degradation of chlorinated ethenes by the mycobacterium ELW-1 and chlorinated ethanes and ethenes by rhodococcus rhodochrous ATCC® 21198™

Creator:: Rich, Stephanie L.
Abstract:: Bioremediation of chlorinated ethenes by the augmentation of contaminated soils with microorganisms is a proposed method of reducing contaminant concentrations in groundwater. To determine the viability of using ELW-1 or R. rhodochrous for groundwater remediation, kinetic analyses of transformation rates must be performed. The focus of this research was to...

Analysis of Chemical Leaching from Common Consumer Plastic Bottles Under High Stress Conditions

Creator:: Dornath, Paul John
Abstract:: There has been much controversy in recent years over the leaching of chemicals from plastic water bottles. In this study, two of the most common plastics used in water bottles, polyethylene terphthalate (PETE) and polycarbonate (PC) were studied. The leaching of the chemical bisphenol-A (BPA) from polycarbonate (Nalgene ™, Camelback...

Hypothalamic Leptin Gene Therapy Does Not Prevent Ovariectomy-Induced Bone Loss in Rats

Creator:: Jackson, Melanie A.
Abstract:: Post-menopausal women are at an increased risk for osteoporosis due to increased bone resorption associated with estrogen deficiency. Subcutaneous administration of leptin, a hormone produced primarily by adipocytes, attenuates bone loss in the ovariectomized (ovx) rat, an animal model for post-menopausal bone loss. Leptin has both direct peripheral and indirect...
