Anthropogenic and Climate Impacts on Groundwater Resources in the Lower Apalachicola-Chattahoochee-Flint River Basin

Mitra, Subhasis (2015-01-07)

El Niño Southern Oscillation (ENSO) is one of the major climate variability cycles around the world and is responsible for droughts in the Southeast United States. These ENSO-induced droughts have been responsible for ...

Assessing Private Well Water Quality in Mobile and Baldwin Counties, Alabama

Millner, Sidney (2024-04-29) ETD File Embargoed

Approximately 43 million people in the United States rely on private well water. Lack of regulation is important due sources of contamination from geogenic and anthropogenic sources. One source of anthropogenic contamination ...

Assessing Transformation of Trace Metals and Crude Oil in Mississippi and Louisiana Coastal Wetlands in Response to the Deepwater Horizon Oil Spill

Keevan, Jeffrey (2012-06-28)

On April 20, 2010, the drilling rig Deepwater Horizon exploded in the Gulf of Mexico, resulting in the release of about 5 million barrels of crude oil into the environment. Coastal wetlands are particularly susceptible to ...

Bioremediation of an Arsenic-Contaminated Site, Using Sulfate-Reducing Bacteria, Bay County, Florida

Saffari Ghandehari, Shahrzad (2016-08-05)

In this study an in-situ bioremediation field demonstration project using sulfate-reducing bacteria was conducted at an As-contaminated site, in Bay County, Florida. The background levels of As ranged from 0.13 to 0.34 ...

Bioremediation of Arsenic Contaminated Groundwater in Northwest Florida: Mineralogy, Geochemistry, and Microbiology Changes

Levitt, Eric (2017-04-21)

This research demonstrates that the stimulation of natural sulfate-reducing bacteria (SRB) in groundwater can precipitate biogenic pyrite nanoparticles that play an active role in sequestering dissolved arsenic from ...

Characterizing the Geological and Geochemical Properties of Selected Gas Shales and their Thermal Maturation in the Black Warrior Basin, Alabama

Marlow, Christopher (2014-07-22)

This study will focus on selected gas shale’s, geological and geochemical properties in Alabama’s Black Warrior Basin, which contains Cambrian through Mississippian shales; these gas-shales that may potentially produce ...

Clustered Seismicity in Alabama: Natural or Anthropogenic?

Chen, Jian (2017-07-27)

Seismicity in the central and eastern U.S. is typically characterized by low-magnitude earthquakes (M < 4) with a random distribution that occur in areas of low to moderate strain rates. An unprecedented increase in ...

A Comparative Study of Site Response in Western Washington Using Earthquake Data

Keshvardoost Jobaneh, Ruhollah (2014-08-18)

Broadband and strong motion seismic data from three moderate to large earthquakes were used to determine site response characteristics in the Seattle and Tacoma, Washington, area. The three earthquakes chosen for analysis ...

Development, Numerical Implementation, and Application of Methods to Simulate Solute Transport Processes in Porous Media Systems

Bedekar, Vivek (2019-04-16)

Solute transport in porous media has been the attention of a plethora of studies over the last several decades. This research identifies gaps in existing knowledge within the realm of solute transport in porous media systems ...

Evidence for Deformation and Faulting in the Muckleshoot basin, Washington

Cox, Justin (2015-05-05)

The Muckleshoot basin of Western Washington state extends from the western base of the Cascades to approximately 10 km east of the Puget Sound. Mapped traces of the Tacoma and White River fault systems, to the west and ...

Experimental and Modeling Investigation of Arsenate adsorption on Synthetic Iron-coated sand

Jeppu, Gautham (2011-04-21)

Arsenic is an environmental contaminant of worldwide concern due its high toxicity and presence in groundwater aquifers. Adsorption of arsenic onto metal-oxides is an important phenomenon that locally controls the transport ...

Factors Affecting Arsenic Mobilization in Experimental Subsurface Systems

Radu, Tanja (2007-12-15)

Elevated concentrations of arsenic (As) in groundwater is a widespread problem that affects millions of people around the world. Other than the adverse affects on human health, this problem often raises economic, social ...

Fate and Transformation of Oils and Trace Metals in Alabama and Louisiana Coastal Marsh Sediments Associated with the British Petroleum Gulf Oil Spill

Natter, Michael (2012-04-10)

The effects of the 2010 BP Macondo-1 well oil spill on the geochemistry of sediments and water columns at ten Gulf salt-marsh sites were investigated, months after the spill ceased. The ten sampling sites include four ...

Field and laboratory investigations of groundwater arsenic sequestration in biogenic pyrite at an industrial site in Florida

Fischer, Alicia (2020-05-07) ETD File Embargoed

Pumping groundwater from arsenic-contaminated aquifers has exposed millions of people around the world to high and potentially deadly doses of the contaminant. Moreover, developing countries lack the resources and technology ...
