Laboratory and field studies have been previously performed in support of enhancing free product hydrocarbon recovery with the use of hydrophobic filter pack designs. This study was an attempt to test the efficacy of using hydrophobic filter pack materials to enhance free product recovery.

Six recovery wells were installed at three field sites, each site utilizing a pair of recovery wells, one hydrophobic and one hydrophilic, to compare their performances. Fine-grained hydrophobic filter pack …

Competitive Effects Of Uranyl-Organic Complexes On U(Vi) Reduction By Shewanella Putrefaciens, Abraham M. Northup

Masters Theses

Haas and DiChristina (2002) have demonstrated that Fe(III) reduction by the facultative Fe(III)-reducing bacterium S. putrefaciens is mediated by competitive speciation among dissolved organic ligands and functional groups on the cell surface. They also showed that rates of Fe(III) reduction by S. putrefaciens correlate with the thermodynamic stability constants of the Fe(III)-organic ligand complexes. S. putrefaciens can also use U(VI) as a terminal electron acceptor, coupling U(VI) reduction to growth. In this study, S. putrefaciens was incubated in experimental media containing U(VI) in the form of aqueous complexes with a variety of organic ligands that differ significantly in structure and …

Masters Theses

"This study represents a contribution to Early Paleogene biostratigraphy in the tropics where published studies are sparse in comparison with mid and high latitude regions. Data were derived from a comprehensive analysis of dinoflagellate cysts (dinocysts) in 45 samples from the Early Paleocene to Early Eocene interval at two localities in West Africa, namely Alo-1 well in the Anambra Basin, southeastern Nigeria, and Ocean Drilling Program Hole 959D (ODP Leg 159) in the Cote d'Ivoire-Ghana Transform Margin. Dinocyst recovery varied from very good to poor, and the specimens were commonly well preserved. The dinocyst data were calibrated with existing calcareous …

Development Of A Web-Based Gis For Groundwater Exploration In Arid Lands, Nakul Manocha

Masters Theses

A three-fold exercise was conducted to assess the groundwater potentiality in the Eastern Desert (ED) of Egypt. First, a database was generated to host all relevant data sets in a GIS environment for a better understanding of the spatial relationships between these data sets. Co-registered digital mosaics were generated from relevant data sets including remote sensing (e.g., Landsat TM, SIR-C, SRTM, TRMM), geochemical (solute concentrations, O and H stable isotope composition), geological (geologic maps), and hydrological (lithology, depth to water table) data sets. Second, a web-based GIS interface (ArcIMS) was developed to provide a vehicle for data analysis, visualization, and …

Resistivity, Induced Polarization, And Spontaneous Potential Study Of Part Of The Calvin 28 Oil Field, Cass County Michigan, Eric M. Larsen

Masters Theses

Some hydrocarbon reservoirs have a documented reducing chimney, extending upward to the surface due to diffusion of hydrocarbon volatiles. This effect reportedly reduces the iron in the soil to magnetite and precipitates fine-grained pyrite if there is sufficient sulfur in the system. This study was conducted to test the detectability of the hypothetical chimney, using electrical geophysics in an environment of relatively recent glacial cover, known depth to an underlying petroleum reservoir, and known faulting.

The Calvin 28 oil field, in Cass County Michigan, is a middle Devonian domal field where reservoir rocks are draped over the central uplift block …

Investigating Nickel Partitioning In A Contaminant Aquifer, Suama Ndengu

Masters Theses

Improved prediction of the transport and bioavailability of metals in contaminated sediments demands a better quantitative understanding of how metals partition between aqueous solutions and mineral phases. This research examines the partitioning of nickel in a contaminated aquifer from Grand Rapids, Ml. Contaminated aquifer sediments were examined using the five step Tessier et al. (1979) operationally defined sequential extraction procedure to determine the solid phase distribution of nickel in the aquifer sediments. Models used to guide remediation efforts at the contaminated site assume that Ni behavior can be predicted based on Ni adsorption onto ferrihydrite (HFO). Although sequential extraction results …

Seasonal Variability In Trace Metal Speciation And Vertical Redox Stratification Of Freshwater Lake And Marsh Sediments In The Kalamzoo River Watershed (Mi, Usa), Noah Tumusiime Ndenga

Masters Theses

This research was aimed at: 1) quantifying redox-sensitive parameters in order to study redox stratification of the upper freshwater sediments at Asylum Lake and Kleinstuck Marsh, 2) quantifying the speciation of metals (e.g., Pb, Mn, Fe, Cr, Cu, Zn, Co and Cd), particularly with respect to their association with Fe and Mn (hydr)oxide phases, and 3) assessing changes in redox stratification and metal speciation as a function of season in the sediments. Both the solid phase and sediment pore waters were collected to a depth of ~50cm. Pore waters were analyzed for redox-sensitive species and the sediment solid phase was …

An Investigation Of The Interlobate Area West Of Three Rivers, Michigan And Its Relationship To The Late Wisconsinan Glaciation Of Southwest Michigan, Scott J. Kendzierski

Masters Theses

A detailed investigation of selected mineralogical and textural characteristics of glacial deposits was conducted in order to explore the complex relationships between the Lake Michigan and Saginaw Lobe ice-margins and associated depositional regimes during the deglaciation of southwest Michigan. Various analytical methodologies were applied to the characterization of glacial materials, glacial and post-glacial environments in order to infer a chronology of lobate activity.

The Sturgis Moraine, located in St. Joseph County, Michigan, is a major recessional moraine owing to the processes of both the Lake Michigan and Saginaw Lobes. Analysis of geologic materials and examination of subsurface data along with …

Glacial Stratigraphy And Surficial Geology Of The Decatur, Lawrence, And Paw Paw U.S.G.S.7.5 Minute Quadrangles In Van Buren County, Michigan, Brian Bird

Masters Theses

The modern day landscape of Van Buren County Michigan was created by the advance and retreat of glaciers from about 13,000 to 20,000 years ago. The Lake Michigan Lobe of the Laurentide Ice Sheet sculpted southwest Michigan most recently. The sediments deposited by the glacier include diamicton, outwash sediments, and lacustrine deposits. The build up of sediment by the glaciers led to the construction of particular features such as moraines, till plains, and outwash fans. The huge amount of meltwater from the glaciers led to the erosion of channels throughout the area. In the area of this investigation the Ganges …

Slope Stability Analysis Of A Lake Michigan Coastal Bluff, Gregory Carlton Young

Masters Theses

Bluff failure along the Lake Michigan coast can be produced primarily by increased pore pressure from perched water tables above lacustrine clay deposits. To test this theory, a site in Allegan County, Michigan with alternating layers of sand, clay and glacial till was chosen for bluff failure monitoring. Historically, the site experiences sporadic massive failures as opposed to neighboring sites that show more regular and uniform displacements. Four pole and cable monitoring lines were measured bi-weekly from December 2001 to October 2003. Lake levels were low and no erosion of material at the base of the slope occurred. Slumps above …

Geophysical Characterization Of A Former Refinery Site, Kalamazoo, Michigan, Baraka Damas Kinabo

Masters Theses

Lakeside, a former refinery site, in Kalamazoo, Michigan, is contaminated with hydrocarbon products. The contamination resulted from the refining and storage activities that took place at the site for over 50 years. The contamination is scattered in isolated pockets.

In an attempt to better define the contamination zones and therefore assist the remediation efforts, this study uses shallow geophysical methods including Electromagnetic induction using the EM 31 system, Magnetic, Ground Penetrating Radar (GPR), and Resistivity methods. The hand auger was used to further characterize some EM 31 anomalies. The EM 31 conductivity results show elevated values resulting from the biodegradation …

Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck

Masters Theses

It has been proposed that placing a geotextile over sediments with adsorbed contaminants can prevent bioaccumulation of the contaminants in larger animals by isolating the benthic organisms living within these sediments from fish. In conjunction with a field study carried out at Gull Creek, a laboratory study testing two geotextiles as biointrusion barriers and sediment filters was conducted.

Constant-head permeameters were run for seven days using cores from the field study area with a geotextile placed over the cores. For biointrusion barrier tests, medium sand was placed over the geotextile and spiked with nutrients. Following each trial, benthic organisms in …

Application Of Geochemical Fingerprinting And Isotopes To Identity Landfill Gas Impacts To Groundwater, Eric E. Wallis

Masters Theses

Volatile organic compounds (VOCs) are detected in two groundwater monitoring wells (MW-60 and MW-62S) located along the northern, downgradient property line of the McGill Road Landfill (MRL) in Jackson, Michigan. Potential on-site sources for groundwater impact are two distinct landfill units at the MRL. Leachate chemistry suggested that landfill leachate was not the source of VOCs detected in groundwater. A potential source for VOCs was landfill gas. Sources of landfill gas in the vicinity of the impacted wells included the distinct MRL landfill units as well as the old Jackson County Landfill (JCL), located hydraulically downgradient from the impacted wells. …

Stratigraphy Of Lake Michigan Lobe Deposits In Van Buren County, Michigan, Steven P. Beukema

Masters Theses

The surficial glacial deposits and landforms of Van Buren County were recently mapped at a 1:24,000 scale as part of a STATEMAP project. Several borings were drilled to supplement the surface data. Six of these borings were characterized in detail by means of gamma ray logging, textural analysis, and X-ray diffraction of the clay-sized fraction of the diamicton units.

Results from this study reveal two diamicton units at stratigraphically distinct positions that can be correlated across the county and that are separated by a thick sequence of lacustrine sediments. Correlation of diamicton and lacustrine units was accomplished by analyzing several …

A Geochemical Survey Of The Natural Waters Of Belize, Central America, Anthony D. Marfia

Integrated Geophysical Examination Of A Former Refinery Site, Carson City, Michigan, Kennedy Opiyo Mwanda

Masters Theses

Integrated geophysical surveys, including electromagnetic (EM-31), magnetic, dc resistivity, and ground penetrating radar (GPR) methods and soil borings were used to investigate part of a former refinery site in Carson City, Michigan, which has more than a 50-year history of hydrocarbon contamination.

Although not readily evident on the magnetic anomaly maps, the EM-31 conductivity map clearly revealed many sections of buried pipes of various lengths and orientations. Also evident on the EM maps are extensive near surface conductivity anomalies. Soil borings in zones of anomalous conductivities to the west suggest the presence of shallow clays with pooled hydrocarbons at depths …

Inorganic And Organic Chemistry Of The Former Lakeside Refinery In Kalamazoo, Michigan, Kurt W. Carlson

Masters Theses

The focus of this investigation of the Lakeside Refinery site is the inorganic geochemistry because previous investigations concerned organics and heavy metals. Because little nitrate is in native groundwater, high dissolved ammonia immediately downgradient from a petroleum body suggests the source is the petroleum and/or associated byproducts. Iron reduction is most prominent immediately upgradient from the known and measurable petroleum while manganese reduction occurs mostly downgradient. Sulfate reduction occurs mostly towards the southern portion of the light petroleum LNAPL. Based on concentrations of nitrate, manganese, iron and sulfate along a groundwater flow path, there appears to be a sequential use …

Microbial Community Structure In Hydrocarbon Impacted Sediment Associated With Anomalous Geophysical Signatures, Joseph W. Duris

Masters Theses

The Crystal Refinery is a former refinery site in Carson City Michigan that has had historic releases of refined and unrefined crude oil dating back to the late 1940's. The contamination of soil with light non-aqueous phase liquids (LNAPL) has had a dynamic impact on the subsurface environment in adjacent Carson City Park. Very little is known about the complex interactions between microbial communities, geochemistry and geophysics. In order to investigate possible connections between these parameters a multidisciplinary study was undertaken to investigate the hypothesis that the degradation of LNAPL by resident microbial communities causes a local increase in organic …

The Role Of Groundwater And Surface Water Interaction In The Development Of A 1,4-Dioxane Plume In Scio Township, Washtenaw County, Michigan, James W. Brode

Masters Theses

The purpose of this study was to examine the hypothesis that groundwater and surface water interaction resulted in the development a 1,4-dioxane plume in a glacial aquifer in Scio Township, Washtenaw County, Michigan.

An industrial solvent, 1,4-dioxane, was detected in the groundwater in the area of study in 1986. This area, referred to in this investigation as the Western Plume, is one of several 1,4-dioxane plumes associated with the Pall/Gelman Sciences Inc. (P/GSI) site, an extensively investigated site of groundwater contamination.

1,4-Dioxane in the Western Plume area was initially believed to be the result of contaminated groundwater transported from a …

Multiple Isotopic Investigation Of Lake Sediments From Northern India, Alice Mwanda

Masters Theses

Stable isotopes ratio of lake sediments can provide valuable environmental information. This possibility has been investigated using radiocarbon dated fossil lake sediments from the Himalayan region of Northern India. The chronology was established using Radiocarbon dating of both organic and inorganic fractions using (AMS). Inorganic ages are older than organic ages. Organic ages are expected to increase stratigraphically, however several anomalous old ages are found in the younger part of the sediments. Final chronology, determined using selected sensible ages identified two periods of sedimentation. The high sedimentation period is characterized by sedimentation rate of 0.8cm/yr and it fairly coincides with …

Determining Flow Type In A Carbonate Bedrock Aquifer, Presque Isle County, Michigan, Bonny Armstrong

Masters Theses

Presque Isle County, Michigan, has a long history of ground water quality problems. Aquifer contamination is most likely the result of large fractures in the bedrock allowing surface water to rapidly reach ground water. The purpose of the study is to l) perform a geochemical investigation of ground water in the bedrock aquifer, 2) suggest the type of ground water flow system present in the study area and characterize the aquifer type, and 3) suggest how the flow system might affect the behavior and transport of contaminants.

Water samples were collected from sixteen wells in the Genshaw Formation, three wells …

Electrical Resistivity Tomography And Induced Polarization Techniques With Paired Vertical Resistivity Probes, Adrian Ezeagu

Masters Theses

The aim of this research is to use electrical resistivity and induced polarization (IP) techniques to image in detail the vertical and lateral distribution of resistivity and chargeability in the subsurface region between two or more boreholes. The method involves installing electrodes mounted on PVC pipes in the boreholes. The distribution of resistivity and chargeability around the boreholes is then calculated. The large number of measurements taken is then inverted to produce tomographs or images showing subsurface distribution of resistivity and chargeability. Four cross-hole measurement arrays (pole-pole, dipole-pole dipole-dipole and pole-dipole) were employed in acquiring tomographic data. The tomographs produced …

Stratigraphic Analysis Of Diamicton Units In Southern Allegan County, Michigan, Shannon A. Wong

Masters Theses

Two diamicton units from the southern Allegan County, Michigan lakeshore bluffs were identified and differentiated through clay mineralogy by analysis of 7 /10A peak-height ratios and the 2-80 mm crystalline fraction from pebble count results. t-Tests indicate the two units are significantly different. These two units are correlated with the Saugatuck and the Ganges tills of southwest Michigan based on similarities in stratigraphic position and lithologic description as described by Monaghan et al. (1986). Other diamicton samples were collected throughout southwest Michigan, near Moline, Otsego, Bloomingdale, Gobles, and Decatur. In correlating the Saugatuck and the Ganges tills to their inland …

Stratigraphy And Diagenesis Of The Paleoproterozoic Bushy Park Zinc-Lead Deposit, South Africa, William Daniel Baugaard

Masters Theses

“The Bushy Park zinc-lead deposit is located in the Northern Cape Province, South Africa. The sulfides are hosted by karst-related breccias that were formed in carbonate shelf deposits of the Neoarchean (2.55 Ga) Campbellrand Subgroup. These rocks are dolomitized completely and silicified partially but have not undergone major metamorphism and thus display remarkable preservation of depositional fabrics. The stratigraphic interval includes the Papkuil and Klippan Formations (> 210 m), a sequence of cyclic microbial laminates interbedded with domed and columnar stromatolites. The Klippan is distinguished from other formations b intense silicification and brecciation. These strata are overlain by the Kogelbeen …

The Geochemistry Of A Leaf Composting Leachate Plume, Asylum Lake, Kalamazoo, Michigan, Eric G. Steeves

Masters Theses

Since the implementation of legislation that bans yard waste from landfills, there has been a need to characterize the impact that large scale composting has on groundwater quality. Allen (1993) and Weaver (1995) have attempted to characterize a leaf composting leachate plume located at the WMU-Asylum Lake Well Field #2 in Kalamazoo, Michigan. Allen was not able to base any conclusions on geochemical results and Weaver delineated the plume using fewer monitoring wells than are now available.

The data from twenty-one monitoring wells indicates that local groundwater is being impacted by the large-scale composting operation. The plume is characterized by …

In Situ Biosurfactant Production At Carson City Park, Michigan, Andrew J. Hudak

Masters Theses

Crude oil refining operations conducted by the Crystal Refining Company in Carson City, Michigan have led to the contamination of the soil and groundwater at Carson City Park with petroleum hydrocarbons. In situ biosurfactant production, occurring as a result of the biodegradation activities of hydrocarbon degrading microorganisms, was investigated.

Background hydrogeological and biogeochemical data were collected from the groundwater from thirteen monitoring wells at Carson City Park. Further analysis included the identification of biosurfactant producing microorganisms and biosurfactants present in the soil and groundwater.

Results showed that Pseudomonas aeruginosa was producing both monorhamnolipids and dirhamnolipids (glycolipid biosurfactants) in the contaminated …

Apoptosis Following Peripheral Sensory Deafferentation In The Olfactory Blub Of Adult Zebrafish, Danio Rerio, Akiko M. Vankirk

Masters Theses

Removal of the olfactory organ in the adult zebrafish results in a significant decrease in volume of the ipsilateral olfactory bulb. Our lab has been investigating the potential role of apoptosis in this phenomenon. My hypothesis is that cells in the adult olfactory bulb normally undergo minimal apoptosis and that apoptosis will increase when sensory stimulation is removed. The TUNEL method allowed detection of cells undergoing DNA-fragmentation, which indicates an apoptotic response. Double-label immunohistochemistry was used to mark which apoptotic cells are neurons by using antibody to Hu, a neuron specific protein. Triple-labeling with bis-benzirnide confirmed the apoptotic nature of …

Constraining The Crystallization And Post-Crystallization History Of The Wallamatogus Pluton, Maine, Using Compositional Data From Garnet, Biotite And Muscovite, Joy Kathleen Drake

Masters Theses

"The Wallamatogus Pluton, Maine, exhibits systematic variation in grain size, mineralogy, and phenocryst abundance (alkali-feldspar) from the margin to the center of the pluton. Three facies are recognized: 1) outermost, seriate, coarse-grained (Owe), 2) porphyritic medium- to fine-grained (Dwp ), 3) innermost, fine-grained equigranular (Dwf). These facies are concentrically arranged and their contacts are gradational. Muscovite and biotite occur in all facies; the outer two facies contain garnet, and tourmaline. Muscovite and biotite grains within micaceous enclaves compositionally overlap primary muscovite, suggesting that they are early-crystallized accumulations. Muscovite in multiphase clusters and secondary muscovite compositionally overlap, suggesting formation during post-crystallization …

Eustasy Determination From Borehole Data, Onshore New Jersey: New Boreholes And New Porosity Estimates, William Alan Van Sickel

Masters Theses

Backstripping analysis of detailed stratigraphic data from the Bass River and Ancora boreholes on the New Jersey Coastal Plain (Ocean Drilling Project Leg 17 4AX) was conducted to test and refine previous eustatic estimates (Kominz et al., 1998) and provide new Upper Cretaceous estimates. Porositydepth relationships required by the backstripping method were estimated to supplement those from the Cost B-2 well (Rhodehamel, 1977). Sand and mud porosity at shallow depths (<500 m) obtained here are higher than was seen at the Cost B-2 well.

The Bass River and Ancora boreholes targeted older sequences of the Upper Cretaceous to Paleocene. This new data allow for more accurate estimate of the magnitude of long-term sea-level …
