Modification, Transport, And Sources Of Hydrocarbon Oxidation Products From Groundwater At Crude Oil And Diesel Spill Sites In Minnesota: Unveiling Common “Theems” Via Spectroscopy & Chromatography, Eduardo E. Turcios Valle
Modification, Transport, And Sources Of Hydrocarbon Oxidation Products From Groundwater At Crude Oil And Diesel Spill Sites In Minnesota: Unveiling Common “Theems” Via Spectroscopy & Chromatography, Eduardo E. Turcios Valle
LSU New Orleans Theses and Dissertations
In this thesis, petroleum-contaminated groundwater from three spill-affected Minnesota sites—two contaminated with crude oil; one with diesel—is investigated to elucidate whether differences in degradation products from different parent oils exist. After spill events, parent molecules from the leaked oil seep underground and undergo microbial degradation over time, transforming into hydrocarbon oxidation products (HOPs), water-soluble contaminants that infiltrate groundwater aquifers, flowing into nearby environments and towns while exhibiting environmental persistence, toxicity to aquatic biota, and potential risks to humans that become exposed. Spectroscopic and chromatographic study of the structural themes and spatial distributions of HOPs reveals preferential degradation of aliphatic (biolabile) …

Influence Of Elevation On Plant Survivorship In Baduwa’T Estuary, Richard Louis Toledo Jr., Celine Aguilera, Rivé Prater, Claire Durbin
Influence Of Elevation On Plant Survivorship In Baduwa’T Estuary, Richard Louis Toledo Jr., Celine Aguilera, Rivé Prater, Claire Durbin
Undergraduate Scholarship
The Baduwa’t is a river in Humboldt County, California that has been adversely impacted by agricultural operations. Disturbances from agriculture have altered the surrounding ecosystems and hydrology of the river. The conservation stewardship group, California Trout, initiated a collaborative restoration project that created a new channel and off-channel pond to provide habitat for salmonids and other native fish in the estuary. As an extension of this project, sections of the site underwent revegetation efforts. The survivorship rates of this new vegetation were lower than anticipated and we were asked by California Trout to assess if the elevation on the site …
Groundwater Vulnerability Assessment And Dye Trace Of War Fork River In Daniel Boone National Forest, Will Hemenover
Groundwater Vulnerability Assessment And Dye Trace Of War Fork River In Daniel Boone National Forest, Will Hemenover
Mahurin Honors College Capstone Experience/Thesis Projects
Daniel Boone National Forest plays a key role in preserving much of Kentucky’s karst regions, natural resources including timber, mineral deposits, and biodiversity, including over 300 species of concern. The health of these environments is determined by surface and groundwater streams in the forest, and karst systems are an integral environment where these systems are active. War Fork, a tributary to the Kentucky River in Jackson County, Kentucky, is a remote and understudied hydrologic system in the Daniel Boone National Forest that contains recreational and logging land uses. Due to karst areas being susceptible to contamination because of rapid water …
Assessing Microplastic Contamination Within Karst Groundwater Basins In Kentucky, Maaz Fareedi
Assessing Microplastic Contamination Within Karst Groundwater Basins In Kentucky, Maaz Fareedi
Theses and Dissertations--Earth and Environmental Sciences
The input and abrasion of plastic waste in the environment has long been known to form microplastics (MPs). These ubiquitous contaminants are easily mobilized into hydrologic systems. MPs are now being found in karst aquifers around the world, including several across Kentucky, USA. Due to their size (< 5 mm in diameter), chemical properties, abundance, and wide distribution, MPs pose numerous ecological hazards, including uptake by organisms and as substrates for contaminant sorption. Karst groundwater is especially vulnerable to surface contaminants; however, knowledge of the extent of karst MP contamination is limited, with most studies focused on individual sites or small areas. In this study, we created a MP contamination dataset for 30 karst springs and 10 locations where cave sediments were characterized across Kentucky. MP concentrations in groundwater samples ranged from 0 to 41.1 items/L and yielded an average of 4.9 ± 8.7 items/L. Sediment MP concentrations ranged from 0 to 306 items/kg. We performed statistical analyses and linear regressions to examine whether groundwater MP concentrations could be explained by factors including land use, population density, basin area, numbers of sinkholes, and sinking streams. Our models revealed that population density, agrarian land use, sinking stream density, and basin area were related to MP concentrations. All factors except basin area trended positively with MP concentration, while basin area trended negatively. These relations are generally corroborated by existing literature, however they indicate that further studies with considerably larger sample sizes are needed to determine mechanistic relationships.
Geoelectrical And Hydrochemical Characterization Of Submarine Groundwater Discharge In Florida Bay, Ifeanyi Emmanuel Eze
Geoelectrical And Hydrochemical Characterization Of Submarine Groundwater Discharge In Florida Bay, Ifeanyi Emmanuel Eze
College of Graduate Studies: Theses & Dissertations
Florida Bay, situated at the southern tip of Everglades National Park and underlain by the Miami Limestone formation, is an ecosystem of global significance. Over the past century, the bay has faced threats such as droughts, seagrass mortality, and hypersalinity. Despite various studies and management efforts, the dynamics of submarine groundwater discharge (SGD) in the region remain underexplored. Given that SGD plays a significant role in the chemical dynamics of coastal ecosystems, it warrants thorough investigation. This study aims to characterize the spatial and temporal patterns of SGD in Florida Bay by surveying three basins – Rankin, Whipray, and Rabbit …
