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 ... -
Effects of Hydrology, Vegetation, and Aeration on Emerging Contaminant Removal from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
Queen, James (2024-05-10)Indirect potable reuse is an expanding practice which returns portions of treated wastewater to municipal supplies. However, traditional wastewater treatment is not designed to remove the wide variety of “emerging contaminants” ... -
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 ... -
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 ... -
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 ...
