Quantifying The Contribution Of Solid Precipitates To The Total Alkalinity In A Coal-Mine Discharge, Lili Lei, Dorothy Vesper 2021 West Virginia University

Quantifying The Contribution Of Solid Precipitates To The Total Alkalinity In A Coal-Mine Discharge, Lili Lei, Dorothy Vesper

Presentations

Flocculates and precipitates from coal mine drainage (CMD) are an integral part of the geochemical setting in mining-impacted streams. The precipitates may be very small, amorphous, and, depending on their chemistry, play a role in the storage and release of alkalinity. To evaluate the potential impact of CMD-solids on alkalinity, we conducted various tests using model and natural solids. Laboratory measurements of alkalinity are operationally defined by a titration to a fixed pH. When the solid-solution mixtures were tested using the standard alkalinity measurement method, no alkalinity could be detected; however, a possible reason for that was that the standard ...


Comparison Of Methods For Estimating Carbon Evasion And Export Associated With A Coal Mine Discharge, Kyle Lee, Dorothy J. Vesper 2021 West Virginia University

Comparison Of Methods For Estimating Carbon Evasion And Export Associated With A Coal Mine Discharge, Kyle Lee, Dorothy J. Vesper

Presentations

The evasion of CO2 from terrestrial waters plays a role in the global cycling of carbon but there are few datasets that have an accurate accounting of the flux. It has been shown that discharges from coal mines can have elevated concentrations of CO2 due to sulfuric acid-driven dissolution of carbonate rock. In this study, we compared three methods for calculating the export dissolved inorganic carbon (DIC) and the evaluation of CO2 from an abandoned-mine discharge in West Virginia. In Method #1, the source flux is calculated from the discharge and the concentrations at the portal. In Method #2, the ...


Evaluating Impacts Of Anthropogenic Disturbance To Wetland Water Quality Functions, Sindupa De Silva, Jim Anderson, Jason A. Hubbart, Michael P. Strager, Elliott Kellner, Christopher T. Rota, Elizabeth A. Byers 2021 West Virginia University

Evaluating Impacts Of Anthropogenic Disturbance To Wetland Water Quality Functions, Sindupa De Silva, Jim Anderson, Jason A. Hubbart, Michael P. Strager, Elliott Kellner, Christopher T. Rota, Elizabeth A. Byers

Presentations

Wetland ecosystems play fundamental roles in regulating our freshwater resources, yet they are not comprehensively protected from degradation and loss. West Virginia, USA has wetlands across diverse landscapes and geography that feed into both the Chesapeake Bay and Gulf of Mexico. The state is also comprised of diverse anthropogenic land-use practices. We are assessing 200 wetlands over 2 years to evaluate how anthropogenic disturbance impact wetland water quality functions. Select water quality parameters (20), and relative diversity and abundance of vegetation and macroinvertebrates will be used as bioindicators. They will be compared with GIS assessments of watershed land cover/ land-use ...


Relating Recharge Mechanisms To Dissolved Inorganic Carbon Dynamics In An Updip Appalachian Coal Mine Discharge, Matthew L. Bell 2021 West Virginia Unviersity

Relating Recharge Mechanisms To Dissolved Inorganic Carbon Dynamics In An Updip Appalachian Coal Mine Discharge, Matthew L. Bell

Presentations

Impaired drainage from active and abandoned mines degrades the water quality of receiving streams and aquifers. Coal mine drainage (CMD) has been studied for decades in Appalachia, but unknowns and uncertainties are still present, including the influence of mine hydrogeology on the outflow chemistry of above-drainage mines. To evaluate the influence of recharge type on above-drainage mine dissolved inorganic carbon chemistry, samples were collected every two weeks at a CMD outflow treatment system in Harrison County, West Virginia. Samples were collected to measure geochemical changes taking place in the mine workings and along the flowpath of the passive treatment system ...


Do Mitigated Wetlands Support Similar Small Mammal Communities As Natural Wetlands?, Krista Noe, Mack Frantz, Christopher T. Rota, Jim Anderson 2021 West Virginia University

Do Mitigated Wetlands Support Similar Small Mammal Communities As Natural Wetlands?, Krista Noe, Mack Frantz, Christopher T. Rota, Jim Anderson

Presentations

Wetlands provide many ecosystem services and play an important ecological role in wildlife communities. Although wetland mitigation is a standard tool to combat losses to natural wetlands, it is essential to understand if mitigated wetlands are truly replacing natural wetlands in their full capacity. Because one important role of wetlands is to provide habitat for wildlife communities, it is important to determine if these created or restored wetlands can foster a wildlife community that is similar to natural wetlands. One understudied taxa in the realm of wetland mitigation research is small mammals. Our objectives are to examine community composition, occupancy ...


Development Of A Python Library To Facilitate Wqx Dataset Exchanges, Jonathan Musselwhite, Fernando Rojano 2021 West Virginia State University

Development Of A Python Library To Facilitate Wqx Dataset Exchanges, Jonathan Musselwhite, Fernando Rojano

Presentations

The assistance of programming tools to speed up the exchange of water quality datasets are necessary. These tools reduce and simplify the steps currently needed to transfer datasets from water quality monitoring stations to public databases. Here it is presented a library developed in Python that programmatically covers the steps related to the upload of datasets following the framework of the Water Quality Exchange (WQX) of the US EPA. This library is mainly characterized by its ability to efficiently connect and transfer data formatted as CSV or XLSX files via the WQX to the National STORET Data Warehouse by mostly ...

Functionalized Polycarbonate Commercial Filters For Water Purification, Jeremy Mccloud, Ashton Caruthers, Kennedy Shoults, Rick Sharpe, Sean P. Mcbride

Presentations

Can commerercially available filtration membranes be easily functionalized in such a way to enhence the removal the charged contaminants in the water treatment process? The literature demonstrates there have been two pioneering works that demonstrated that Ultrathin Self-Assembled Nanoparticle (USANP) membranes (composed of ~5 nm diameter metallic gold nanoparticles surrounded by organic ligands) when applied to commercial membranes displayed charge sensitive rejection to molecular dyes and also have the ability to charge modify the openings in commercial filters. The rejection mechanisms in these works are proposed to be either size dependent or charged based. Recent experimental results have demonstrated that ...

Emergence and spread of Covid-19 initiated diversified researches based on spatial analysis in visualization, exploration, and modelling of this infection. This short communication is an attempt to comprehend the geographic distribution and spatial clustering of Covid-19 in year 2020. Main objective is to spatially analyze Covid-19 incidence rates, identification of hotspots and clusters outliers at global level. Monthly data of reported cases were taken from World Health Organization dashboard and situation reports. Incidence rate was calculated for each country for each month. Spatial autocorrelation techniques of Global Moran are I and Anselian Local Moran’s I were used to examine ...


Incorporating Life Into Living Shorelines: Can Gulf Ribbed Mussels Reduce Shoreline Erosion And Enhance Restoration Practices?, Jordan Logarbo 2021 Louisiana State University and Agricultural and Mechanical College

Incorporating Life Into Living Shorelines: Can Gulf Ribbed Mussels Reduce Shoreline Erosion And Enhance Restoration Practices?, Jordan Logarbo

LSU Master's Theses

The gulf ribbed mussel (Geukensia granosissima) exists throughout the Gulf of Mexico and influences biotic and abiotic environmental attributes as an ecosystem engineer. Ribbed mussels are an important component of marsh ecosystems providing services including filtering particulate matter, depositing and transforming nutrients in the system, increasing soil strength via byssal threads and providing structure via their shells.

The spatial distribution of mussels along the marsh edge of Sister Lake, LA was investigated via a broad survey of 150 sites, in relation to elevation, exposure and vegetation percent cover. This survey was followed by a second survey at a subset of ...
