APPLICATION OF ECOSYSTEM ENERGETIC INDICATORS FOR THE VALUATION OF ECOSYSTEM SERVICES AND HEALTH
Brumley, Jessica (2014)Ecosystems services are benefits that humans receive from ecosystem functions. Ecosystem health is a term that is commonly used in the literature to describe the state of an ecosystem. Ecologists and economists have stated ... -
Assessing risk and potential reuse of hard rock mine drainage passive treatment residual solids
McCann, Justine (2021-08)Ecologically engineered mine drainage passive treatment systems rely on a series of biogeochemical reactions to decrease concentrations of ecotoxic trace metals and have proven to be an effective way to improve water quality ... -
Assessing the potential for beneficial reuse of passively-treated mine waters for livestock watering and crop irrigation
Stanfield, Harper (2020-12-18)Passive treatment of mine drainage provides demonstrated water quality improvements and substantial removal of ecotoxic metals via biogeochemical, microbiological, and physical mechanisms. When mine drainage is treated to ... -
Characterization of the iron sulfide oxidation products formed during reductive dechlorination of chlorinated aliphatic contaminants
Lan, Ying (2016-05)The overarching objective of this research is to investigate the transformation of iron sulfide, mackinawite (FeS), in contaminated environments. A special research focus is to investigate the FeS oxidation products formed ... -
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 ... -
Ecosystem Structural and Functional Indicators to Evaluate Conservation Easement Success in the Horse Creek Watershed near the Grand Lake o' the Cherokees, Oklahoma
Wilcox, David (2022-12-17)Stream restoration activities in the United States commonly seek to improve aquatic and riparian structure. Traditional assessment methods evaluate ecosystem structure by estimating metrics such as biotic community ... -
Effects of Hydraulic Design and Retention Time on Removal of Constituents of Emerging Concern from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
Overton, Olivia (2023-12-15)Treatment wetlands (TWs) are an ecologically engineered, natural infrastructure approach designed specifically for water quality improvement via natural biogeochemical, physiochemical, and microbiological processes. The ... -
Evaluating Low Impact Development Best Management Practices as an Alternative to Traditional Urban Stormwater Management
Holzbauer-Schweitzer, Brandon (2016-08-12)The Trailwoods residential neighborhood (Norman, OK) included two instrumented watersheds (each approximately 2.3 acres), with the purpose of quantifying the impact on stormwater quantity and quality through implementation ... -
Evaluation of Catchment-Scale Stormwater Runoff Management on First-Flush Water Quality and Storm Discharge Quantity
Berg-Mattson, Noah (2018-12)Urbanization and resulting imperviousness has caused increased pollutant loadings into receiving water bodies. One of the main sources of pollutant loads is stormwater runoff. The purpose of this study was to investigate ... -
Evaluation of Phosphate Recovery and Release Performance of Calcium Silicate Hydrate Made From Rice Husk
Sharmin, Nusrat (2020)In this study, calcium silicate hydrate was synthesized using silica-rich rice husk for recovering phosphorus from wastewater and reusing it as fertilizer under simulated soil conditions. By controlling pH and inhibiting ... -
EVALUATION OF STORMWATER TREATMENT BY VARIOUS REACTIVE MEDIA FOR BIORETENTION CELL DESIGN CONSIDERATIONS
Nguyen, Derrick (2018-05)Bioretention cells (BRC) can be effective at filtering particulate pollutants from stormwater runoff, but substantial removal of the dissolved pollutant fraction is challenging. Various reactive treatment media for BRCs ... -
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
