Determination and Prediction of Products of Trace Metal Removal in Laboratory and Field Scale Vertical Flow Bioreactors
LaBar, Julie (2016-05)Mine drainage is characterized by elevated concentrations of dissolved iron, sulfate, and trace metals and generally exhibits an acidic pH. These constituents, particularly trace metals, can pose serious risks to both ... -
Development of ecological engineering solutions to mine water biogeochemistry and hydrology challenges
Shepherd, Nicholas (2022-05)Abandoned underground mines can cause a variety of environmental problems, including mine drainage (MD) that negatively impacts thousands of kilometers of streams worldwide. Underground mines accumulate water after pumping ... -
Expanding In-situ Surface Water Quality Monitoring Techniques for Optically Complex Inland Waters Utilizing small Unoccupied Aerial Systems (sUAS)
Holzbauer-Schweitzer, Brandon (2021-05-14)Remote sensing is described as the art and science of interpreting information (e.g., reflectance) collected from a target object (e.g., vegetation) using technology (e.g., satellites, occupied aircraft, and small unoccupied ... -
Freshwater Stream Monitoring Process Improvements for Fecal Indicator Impairment Designation
Graves, Grant (2023-05)Recreational water quality standards for freshwater streams and rivers are important to understand the potential human health risks associated with primary body contact recreation. Indicator bacteria, Enterococcus and ... -
The Impact of a Private Water Enterprise on Household Water Services in Rural Ghana
Deal, Philip (2020-05-08)The goal of this dissertation is to investigate the effectiveness and sustainability of a private water service delivery model in a rural, developing context. Recent studies have found evidence for greatly increased ... -
An integrative ecological and evolutionary genomic study of lake Daphnia across time
Wersebe, Matthew (2023-05-12)An undisputable fact of the modern age is that human activities are now a major force shaping the biosphere. Some have called for a new geological epoch called the “Anthropocene” or the age of humans— the search is underway ... -
INTERACTIONS BETWEEN FRESHWATER MUSSELS, MERCURY CONTAMINATION, AND GLOBAL CLIMATE CHANGE IN FRESHWATER SYSTEMS
Tweedy, Brent Norris (2017)Humans are impacting the environment at an unprecedented scale, with anthropogenic activities altering environmental processes and cycles planet-wide. Centuries of gold mining and coal burning has more than tripled the ... -
AN INVESTIGATION OF SUSTAINABLE FLUORIDE WATER TREATMENT TECHNOLOGIES WITH A FOCUS ON ETHIOPIA
Brunson, Laura R. (2014)Human consumption of unsafe drinking water from an unimproved source is a global issue affecting approximately 748 million people worldwide. While this number has been decreasing in recent years, an additional 1.2 billion ... -
INVESTIGATION OF THE HYDROLOGY, FLUVIAL GEOMORPHOLOGY, AND SEDIMENT TRANSPORT IN THE LAKE THUNDERBIRD WATERSHED IN CENTRAL OKLAHOMA
Dutnell, Russell (2015-05-08)As human population continues to rise, an ever increasing burden is being placed on earth’s water resources. Between 1950 and 2010, the world’s population increased from 2.6 billion to almost 7 billion, and the population ... -
Iron Transport and Removal Dynamics in the Oxidative Units of a Passive Treatment System
Oxenford, Leah (2016-12)Abstract Mine drainage is threat to water systems in legacy mining districts as elevated concentrations of dissolved iron, sulfate, and trace metals have an unmitigated impact on water quality. Changes in pH due to ... -
Novel, low-cost aluminum (hydr)oxide based materials for fluoride-impacted drinking-water: Batch and column studies
Du, Junyi (2016-05)Simple aluminum (hydr)oxides and layered double hydroxides were synthesized using common chemicals and equipment by varying synthesis temperature, concentrations of extra sulfate and citrate, and metal oxide amendments. ... -
Performance and environmental impact assessment of agricultural waste-based sorbents for phosphorus recovery and reuse
