Evaluating Remote Economic Benefits Of Watershed-Scale Acid Mine Drainage Restoration, Rachel E. Pell

Graduate Theses, Dissertations, and Problem Reports

In 2011, the West Virginia Abandoned Mine Lands and Reclamation Program (WVAML) implemented a watershed-scale restoration project in Three Fork Creek, a 103 square-mile watershed in rural West Virginia impaired by acid mine drainage (AMD). This was accomplished through the installation of four in-stream lime dosers in 2011. Due to the great capital investment in the restoration of Three Fork Creek and an interest in applying this watershed-scale approach to other watersheds throughout West Virginia, it is of great interest to demonstrate the successes of this remediation. It has already been demonstrated that the watershed has visibly improved and is …

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 …

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 …

Effects Of Multiple Stressors On Aquatic Macroinvertebrate Communities In A Mixed-Land-Use Watershed, Joellen Stivala

Graduate Theses, Dissertations, and Problem Reports

As urbanization continues, there is a need to identify and understand environmental stressors that impact stream condition in mixed-land-use watersheds. This study analyzed four years of aquatic macroinvertebrate community and environmental data collected from ten sites located at the mouths of first-order tributaries and along the main stem creek of a 23-km², mixed-land-use watershed in central Appalachia. The main objectives were to 1) determine stream ecological integrity by analyzing stream macroinvertebrate taxonomic and trait-based composition and 2) assess which of 23 environmental variables explained significant variability in common community composition metrics (WVSCI, GLIMPSS, Biotic Index, % clingers, etc.). …

Relating Recharge Mechanisms To Chemical Changes In An Updip Appalachian Coal Mine Discharge: A Case Study From Lambert Run, West Virginia, Matthew Lewis Bell

Graduate Theses, Dissertations, and Problem Reports

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 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. Samples were divided …

Three Essays On Water Economics, Fahad Alzahrani

Graduate Theses, Dissertations, and Problem Reports

This dissertation consists of three essays that explore the impacts of changes in public water quality, reliability, and raw water source. The first essay explores the relationship between episodes of contaminated drinking water and health care expenditures in the United States. Using panel data from 48 contiguous states from 2000 to 2011 and spatial econometrics modeling methods, the results indicate that there is positive and statistically significant impact on per capita health care expenditures from the percentage of a state’s population exposed to contamination episodes. The second essay examines the problem of water supply reliability due to aging infrastructure of …
