Ultraviolet photolysis of acetaminophen in a 3D printed continuous flow reactor

Creator:: Goetze, John M.
Abstract:: Finding renewable sources of agricultural fertilizer will be necessary to ensure a stable food supply for future generations. Phosphorus is of particular concern, since mining phosphate rock is the main source and reserves are forecasted to deplete in the next 50 – 200 years. Human urine contains substantial amounts of...

Low Level Quantification of 1,4-Dioxane and Investigation of 1,4-Dioxane Co-Metabolism by Mycobacterium sp. 1A.

Creator:: McKeage, Kevin J.
Abstract:: 1,4-Dioxane (dioxane) is a probable human carcinogen and is often found comingled with chlorinated aliphatic hydrocarbon (CAH) contamination since dioxane is used as a stabilizer in CAH solutions. Dioxane is miscible in water, has a low K[subscript ow], low H[subscript cc], and is highly recalcitrant in the environment. The presence...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

Investigation of the Effect of Copper-Palladium Electrocatalysts on Nitrate Reduction

Creator:: Finstad, Arthur
Abstract:: Nitrate (NO₃-) accumulation in water sources is a serious health and environmental concern. Common methods used to reduce NO₃- accumulation have one or more undesirable traits that limit their efficacy in large-scale decontamination. However, treatment of NO₃- electrochemically is a promising area of study because of the absence of toxic...

Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

Creator:: Schrlau, Jill E.
Abstract:: The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...

Biochar Infiltration Columns for Removal of Antibiotic-Resistant Bacteria in Stormwater

Creator:: Lippman, Lauren
Abstract:: Water is one of the world’s most valued commodities, and antibiotic-resistant bacteria are one of the emerging pollutants of concern. Stormwater runoff picks up pollutants such as bacteria as it runs over impervious surfaces and into waterbodies. This project tested the use of biochar columns as an effective and inexpensive...

Assessment and Service Life Prediction of Microbial Induced Corrosion of Concrete (MICC)

Creator:: Sahan, Feyza N.
Abstract:: Microbial-induced corrosion of concrete (MICC) is a multi-stage deterioration process caused by microbial activity in wastewater infrastructure. MICC is a worldwide issue due to the reduced service life of the wastewater infrastructure and the economic impact associated with increased maintenance and reconstruction costs. This thesis explores two critical aspect of...

Advancing the Understanding and Representation of Ecohydrological Processes using Tracer-enabled Modeling Approaches

Creator:: Finkenbiner, Catherine E.
Abstract:: Climate change impacts everyone’s food and water security. Increasing global temperatures accelerate the hydrologic cycle and consequently impact the water resources for billions of people worldwide. Countless models have been developed to represent various components of the hydrologic cycle at various spatial and temporal scales. These are often validated against...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

Aerobic Cometabolism of cis-Dichloroethylene, 1,1,1-Trichloroethane, and 1,4-Dioxane by Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads that Co-Entrapped Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Column Studies

Creator:: Bailey, Kestrel
Abstract:: CisCis-Dichloroethylene (ciscis-DCE), 1,1,1-Trichloroethane (1,1,1-TCA), and 1,4-Dioxane (1,4-D) are chlorinated solvents used as solvents and degreasers in industrial cleaning agents that have become common groundwater contaminants. To develop an effective treatment method for these compounds, polyvinyl alcohol (PVA) and sodium alginate (SA) hydrogel beads were co-entrappcapsulated with Rhodococcus rhodochrous Strain ATCC...
