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 ... -
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 ... -
Microcosm assessment of natural processes affecting chemicals of emerging concern in secondary effluent
Thornton, Erin (2017-05)The fight for new water sources is over, reclaimed water is next. Currently, the City of Norman supports its water needs via Lake Thunderbird (LT) and the Central Oklahoma Aquifer System (COAS). In times of peak demand, ... -
Quantifying Solar-Powered Removal of Aqueous and Gaseous Sulfide in a Mine Water Passive Treatment System
Wall, Taylor (2018-12-14)Passive treatment systems can improve water quality for mine water discharges. However, some process units, like vertical flow bioreactors (VFBRs), may produce excess sulfide, which can be a source of nuisance odors and ... -
Soil Trace Metals Concentrations in A Mining Impacted Agricultural Watershed: Comparison of Analytical Methods, Geospatial Distribution, and Evaluation of Risk
Sikora, Amy (2018-05-11)This study investigated four aspects surrounding lead, zinc, and cadmium soil trace metals concentrations within a mining impacted watershed: (1) a comparison of three soil trace metal quantification methods relating ... -
SORPTION AND RELEASE OF NICKEL AND ZINC USING A MIXED ALGAE COMMUNITY COLLECTED FROM A MINE DRAINAGE PASSIVE TREATMENT SYSTEM
Fielding, Ellen (2017-05)Mine water from upwellings in Commerce Oklahoma is treated by the Mayer Ranch Passive Treatment System (MRPTS) to remove contaminants. The last treatment section of MRPTS is referred to as the polishing pond (also known ... -
Temporal and Spatial Variations in Sediment Trace Metal Concentrations in Streams, Rivers, and a Reservoir near a Derelict Lead-Zinc Mining District
Folz, Carlton (2021-05)Historic lead and zinc mining in the Tri-State Mining District has ceased, but the legacy of trace metal contamination (Cd, Cu, Ni, Pb, and Zn) throughout the region still exists. This thesis focuses on stream sediments ...
