An Analysis of the Municipal Solid Waste Permitting and Recycling Programs of the State of Alabama

Kearley, Jacob (2013-11-08)

In the past half century solid waste policy has changed significantly as public awareness and the realization of potential environmental hazards of landfills has grown. The State of Alabama has recently begun to experience ...

Biotransformation of Perfluorooctane Sulfonamide (FOSA), 8:2 Fluorotelomer Alcohol (8:2 FTOH), and 6:2 Fluorotelomer Sulfonate (6:2 FTS) in Aqueous Film-Forming Foam (AFFF)-Impacted Soils under Oxic and Anoxic Conditions

Yan, Pengfei (2022-12-05) ETD File Embargoed

The use of aqueous film-forming foams (AFFFs) for fire suppression over decades has resulted in contamination of numerous sites by per- and polyfluoroalkyl substances (PFAS). However, the environmental fate and transformation ...

Development of an Analytical Method for Quantification of Endocrine-Disrupting Phytoestrogenic Compounds in Estuarine Environment Using UHPLC-MS/MS

Qi, Jingyi (2018-04-27)

Endocrine disrupting compounds (EDCs) are nearly ubiquitous in the daily lives of individuals around the globe. Phytoestrogenic polyphenols (PEPPs, also known as phytoestrogens) represent a subgroup of EDCs. They are ...

Development of Qualitative and Quantitative Analytical Methods for the Analysis of Per-and Polyfluoroalkyl Substances (PFAS) in Environmental Samples by UHPLC-MS/MS

Wang, Danyang (2023-12-06)

Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds widely used in industrial and consumer products. Over the years, these substances have been distributed in environmental media, human populations, and ...

Enhancing understanding of mineral accessible surface area to improve simulation of mineral reaction rates in porous media

QIN, Fanqi (2021-07-19)

Geological formations have great potential for large scale carbon sequestration, where the CO2 is mineralized through geochemical reactions. These reactions are rather complex and can potentially alter the formation ...

Evaluation of an Algal Turf Scrubber™ (ATS) Approach for the Remediation of Perfluoroalkyl Substances (PFAS)

Lopes Viticoski, Roger (2019-04-17)

Per- and polyfluoroalkyl substances are a large group of synthetic organic chemicals ubiquitous and persistent in the environment due to their fluorinated alkyl chains. Existing methods for remediation of mixtures of PFAS ...

Evaluation of Subsurface Gypsum-rich Rock in the Context of Geologic Carbon Sequestration

Newsome, Jamie (2023-11-29)

Geological carbon sequestration is a promising means of reducing atmospheric carbon dioxide emissions by capturing CO2 gas and storing it long term in subsurface porous rock. The goal of geologic carbon sequestration is ...

Evaluation of Toxicity Levels and Cytotoxicity Mechanisms of Corexit 9500

Zheng, Mengyuan (2013-07-15)

The 2010 British Petroleum (BP) oil spill in the Gulf of Mexico has raised many ecological and health concerns. BP predominately used Corexit9500A to disperse crude oil in the Gulf of Mexico to prevent shoreline contamination. ...

A Fine Line Between Dispersion and Retention: Oil-Sediment Interactions in Nearshore Marine Environments

Gustitus, Sarah Anne (2017-04-12)

When crude oil that is spilled in a marine environment approaches the shoreline, it can interact with suspended sediment to form either microscopic oil-mineral aggregates (OMAs), or macroscopic surface residual balls (SRBs) ...

Full Scale Testing of Two Excavations in an Unsaturated Piedmont Residual Soil

Burrage, Richard Jr. (2016-01-06)

Residual soil behavior can be difficult to predict using current geotechnical formulas, because it exhibits properties that are not common to transported soils. These unique properties are mainly influenced by the fabric ...

Land Application of Treated Wastewater within the Black Belt of Alabama

Clark, Carey (2023-08-09)

The Black Belt of Alabama is a region of the United States that has seen its population decrease and poverty rise over the last century. The Black Belt was a thriving part of Alabama due to the rich, fertile soil. The dark ...

Modeling of the Wolf Bay and Perdido Bay Watersheds using HSPF

Lusk, Kyle (2017-07-27)

This study is the first stage of the larger project for determining the transport mechanism of endocrine disruptors that flow through the Perdido Bay Basin. Given within are the methods and processes used to perform watershed ...

The Role of Centralized Wastewater Treatment in the Rural Alabama Black Belt

Wilson, Tristan (2023-05-02) ETD File Embargoed

Centralized and decentralized wastewater treatment systems play a major role in protecting human health and U.S. waters from contamination. However, failing wastewater treatment in the rural Alabama Black Belt has become ...

The Role of Data Analytics in Accelerating Assessments of the Impacts of Per- and Polyfluoroalkyl Substances (PFAS) in Source and Drinking Water

Feltman, Meredith (2022-12-05)

Per- and polyfluoroalkyl substances (PFAS) are a large, diverse, and growing family of persistent, mobile organofluorine compounds that are used for a wide variety of industrial and consumer applications, and that are ...
