The Henry Kinsey family was among the first to settle in the Dayton, Ohio, region in the early 19th century. Henry, and his wife Eva, were buried near what is known as the deer keeper’s lodge, a small building where the deer keeper lived, on the modern-day Dayton Veterans Affairs hospital grounds. In the time since they have been buried, the location of their gravesites has been lost. The main purpose of this thesis is to locate and map their graves using multiple geophysical methods. A secondary purpose is to compare the effectiveness of each geophysical method. Three geophysical methods …
Removal Of Select Chlorinated Hydrocarbons By Nanoscale Zero-Valent Iron Supported On Powdered Activated Charcoal, Md Abu Raihan Chowdhury

Nanoscale Zero Valent Iron (NZVI) has shown limited effectiveness in degrading chlorinated hydrocarbons (CHCs), like 1,1,1-Trichloroethane (1,1,1-TCA) and Trichloroethene (TCE), in aqueous solution. A rapid agglomeration behavior of NZVI particles due to van der waals and magnetic forces can negatively impact its overall effectiveness due to increase in particle size, and decline in CHC degradation kinetics. Different support materials, such as clays and activated carbon, have been used to stabilize NZVI particle and reduce agglomeration in aqueous solution. In this bench-scale study, NZVI supported on Powdered Activated Charcoal (PAC) was selected to prepare a composite, called PAC/NZVI, for a more …

Constraining the composition, structure, and origin of basement provinces, deep assemblages of Precambrian rocks, is largely dependent on deep boreholes and geophysical techniques. This is especially true for the eastern U.S. midcontinent. Here, I employ regional 2-D seismic reflection, Bouguer gravity, and aeromagnetic data to interpret the upper crust below west-central Indiana. Seismic reflection data were donated to Wright State University in 2015. Geopotential data are available through the USGS and affiliates. These geophysical data, together, are analyzed in a regional geologic context. Three distinct seismic stratigraphic sequences are observed on 2-D sections. The first, uppermost sequence, typified by continuous, …

For effective geological sequestration of CO_2, it is critical to understand the processes associated with CO_2 movement and trapping in reservoirs, which requires a proper understanding of a diverse set of heterogeneous geologic properties. A highly-resolved data set from the Cambrian lower Mt. Simon sandstone reservoir (Unit A) in Decatur, Illinois, was used in a new approach to analyzing the variance of permeability and porosity. Newly interpreted bedding types, along with other factors, including grain size, and presence of bleached alterations, were considered in the analysis of variance. The results reveal that the factors contributing most to the sample variance …

Mercury (Hg) is a volatile element increasing in concentration in the environment as a result of anthropogenic emissions. Microorganisms can transform mercury into monomethylmercury (MMHg), the form of Hg that bioaccumulates, biomagnifies, and can harm humans and wildlife. Most studies of MMHg bioaccumulation in wildlife have focused on aquatic organisms due to consumption of fish being the primary route of human exposure to MMHg. However, organisms in terrestrial ecosystems also are exposed to MMHg that may impact ecosystem biodiversity, food-web dynamics, and organisms and ecosystem health. I investigated bioaccumulation and maternal transfer of MMHg in spotted salamanders (Ambystoma maculatum) captured …

Human activities have increased nutrient loadings to aquatic ecosystems during the past century. During low river flow in late summer and early fall, excessive concentrations of phosphorus (P) are present in the Lower Great Miami River (LGMR) and contribute to its eutrophication. Although wastewater treatment plants are suspected of being major point sources of P to the LGMR during low river flow, riverbed sediment has not been examined as an additional potential source of P. Benthic P fluxes were measured at 11 representative locations along the LGMR during late summer and early fall of 2015. Sediment and overlying water sampled …

During the summer of 2015 a 2D seismic line (WSU-2015), ~2.3km long, was collected by Wright State University along Watson Road, south of London, Ohio. This seismic line is parallel to and approximately 1/4 km south of `Line 6' of Mayhew (1969), which is one of six analog, single-fold seismic lines within the area that he studied. The focus of this research is to interpret the stratigraphy revealed by the new seismic line, especially to evaluate the existence or otherwise of a fault that Mayhew (1969) inferred in his interpretation. An important step in this new interpretation was to construct …
