Lithologic And Stratigraphic Analysis Of Glacial Diamictons, Sturgis, Michigan, R. Christopher Gardner

Masters Theses

Seven diamictons are identified in the subsurface glacial drift near Sturgis, Michigan using textural analyses and x-ray diffraction of clay minerals. The clay mineral content is quantified by comparing the 7-A/10- A peak height ratios from x-ray diffraction diffractograms of oriented clay-size particle (< 2um) mounts. Two diamictons occur at the base of the drift. Unit 1 is gray , resembling the shale it overlies. The texture of Unit 1 is sandy clay loam to loam and average 7-A/10-A peak height clay mineral ratios of 0.446 ±0.069. Unit 2 is a yellowish-brown diamicton, it overlies Unit 1, and is a sandy loam to loam with average 7-A/10-A clay mineral ratio of 0.657 ±0.151. Diamicton Units 4 and 5 overlie a thick unit of sand and gravel on top of Unit 2. Units 4 and 5 have similar color and texture, however the 7-A/10-A ratios are 1.059 ±0.090 and 0.810 ±0.072 respectively. Unit 6 is a thin diamicton unit, leached of calcite, and x-ray diffraction suggests that there is a range of weathering horzins between borings. Unit 7 is loamy, whereas Unit 8 generally ranges from sandy clay loam to sandy loam with average 7-A/10-A ratios of 0.865 ±0.090 and 1.195 ±0.189.

A Comparison Study Of Water Well Grouting Materials, Sherry L. Callaway

Masters Theses

To prevent contamination from occurring in water wells, and thereby groundwater, the annulus between the well casing and borehole wall must be sealed with a grout that is capable of maintaining a proper seal. Several factors and properties determine the integrity of the grout and the seal formed by that grout.

A field study discovered limitations in all of the tested grout types. Most grouts were found to vary greatly in thickness surrounding the well casing. Bentonite slurry grouts settled excessively. Cement and bentoni tecement grouts did not adhere to PVC well casing. Bentonite-cement grout fractured. The granulated bentonite was …

Laboratory Comparison Of Trench Design Options For Recovering Spilled Oil, Renuka Fernando

Masters Theses

The research goal was to improve the performance of drainage trenches used to recover spilled oil in the subsurface. Different trench designs were compared in two laboratory experiments. The first laboratory experiment clearly demonstrates that the performance of a oil recovering drainage trench could be improved by replacing the standard gravel pack sand used around the drain pipe with mixtures of teflon and sand. The effectiveness of a downgradient impermeable 'backstop' also was studied in the first experiment.

In experiment two, four trench designs were compared: perforated drain pipe; wire-wrapped horizontal well screen; perforated sheet pile; and gravel fill with …

Geophysical Characterization Of A Jp-4 (Lnapl) Contaminated Site At The Wurtsmith, Air Force Base, Oscoda, Michigan, Kristina C. Sprietzer

Masters Theses

The detection of hydrocarbon contamination in the subsurface using geophysical techniques has been based on the known physical properties of high electrical resistivities (ρa) (low conductivities). However, geophysical field investigations at uncontrolled spill sites yield measurements of low resistivity (high conductivity). The purpose of this study is to test that in the natural environment some hydrocarbon spills (in the case of LNAPLs), can exhibit changes with time due to biodegradation, from electrically resistive to conductive. Since time is an important factor, this hypothesis was tested at a site where the time when a hydrocarbon release occurred is known and where …

Reservoir Characterization Of Crystal Field And Analysis Of The Tow#1-3 Hd-1 Well, Montcalm County, Michigan, Heidi Wines

Masters Theses

The goal of this project was to characterize the Dundee reservoir of Crystal oil field using the newly drilled Tow #1-3 well data in conjunction with historical well records to evaluate heterogeneity of facies and their controls on oil production.

From the Tow# 1-3 HD-1 well, three major facies were identified in the reservoir. A non-fractured intertidal grainstone facies provides storage of fluids with its uniform permeability and excellent intercrystalline porosity. The supratidal fractured micrites and open marine fractured biomicrites are interbedded with the grainstone facies providing conduits for fluid migration between the facies. Facies are important controls on oil …

Systematics Of Stable Isotopes And Radionuclides In Precipitation At Kalamazoo, Michigan, Usa, Madhav V. Machavaram

Dissertations

Precipitation samples were collected at Kalamazoo from June 1992 to March 1995. The samples were analyzed for their 8D and 8lgO values. The 5D - 5I80 relationship is comparable to that of Meteoric Water Line (MWL). The monthly mean isotopic values in precipitation exhibited strong seasonality, being higher in summer and lower in winter months. This behavior is apparently a direct consequence of the temperature effect on isotope fractionation.

The summer precipitation at Kalamazoo is derived predominantly from the water vapor originated in the Gulf of Mexico. A box model calculation showed that a Rayleigh type distillation with Gulf moisture …

Geophysical Investigation Of Anomalous Conductivity Associated With A Hydrocarbon Contamination Site, Mike S. Nash

Masters Theses

The high electrical conductivity measured from chemical analyses from ground water below a hydrocarbon contaminated site was the focus of this study. Most theoretical studies have indicated that the electrical conductivity of hydrocarbon contamination is lower than that of the surrounding medium. Geochemical studies at other sites have shown that areas of dissolved fuel oil plume have a higher electrical conductivity. Six methods: Self Potential, Mise-a-la-Masse, Vertical Electrical Sounding, Dipole-Dipole Resistivity Profiling, Electromagnetic Induction, and Ground Penetrating Radar were all used in an attempt to see which method( s) could identify regions of high conductivity.

The findings of this study …

Changes In Channel Morphology And Flood-Plain Ecosystems Of The Green River Between The Flaming Gorge Dam, Utah And The Gates Of Lodore, Colorado, Gloria Christine Celeste Britton

Masters Theses

Closure of Flaming Gorge Dam in 1962 reduced the flow rate and variability of discharge on the Green River below this dam. These changes, coupled with the decreased sediment load due to stilling and sporadic peaking in response to demand for hydroelectric power and controlled releases of up to 4500 cfs to cope with snowmelt have impacted the channel morphology and ecosystems of the main stem Green River between the Dam and the Gates of Lodore. Detailed comparative analysis of channel shape and riparian ecosystems or pre-dam and post-dam aerial photographs revealed that significant changes occurred after closure. Channel width …

Groundwater-Kalamazoo River Interaction Near The Parchment City Wellfield, Parchment, Michigan, W. Richard Laton

Dissertations

A detailed hydrogeologic study of the Kalamazoo River and its interaction with the groundwater was completed near Parchment, Michigan. The Kalamazoo River between Portage Creek and Allegan Dam is a Federal superfund site due to PCB contamination trapped in its sediments. The City of Parchment pumps all of its drinking water from a glacial aquifer 850 feet from the Kalamazoo River. This study focused on the hydrogeology and groundwater/surface interaction of the area through the use of surface and downhole geophysics, installation of monitoring wells and peizometers, seepage meters and chemical sampling. It was determined that the Kalamazoo River is …

Potential Underground Gas Storage Reservoirs In Latvia, Santis Limezs

Masters Theses

The Baltic state of Latvia, produces no natural gas; all natural gas consumed is imported. In order to address future gas needs in Latvia, this study was undertaken to provide geological background and select sites with the best gas storage potential and reduce costs of more detailed field analyses in the next phase of gas storage development. Russia is the sole natural gas supplier and delivers the gas to Latvia via transmission pipelines. The Inchukalns underground gas storage field is the only underground gas storage field in the Baltic states. Although this structure accommodates current needs, projections show additional storage …

Well Screen Characteristics Which Constrain Hydraulic Conductivity Calculated From Slug Tests, Christopher G. Amore

Masters Theses

With the growing concern over ground water protection and waste water management, interest in the use of slug tests to characterize hydraulic properties of aquifers has increased. While slug tests offer an inexpensive alternative to pump tests, problems arise with collection of the tests and the interpretation of the results. Field tests and mathematical studies show that both positive and negative biases of formation properties have been obtained. The resulting errors can be traced to improper analytical techniques, incorrect assumptions of well configuration and aquifer properties, poor well installation and data gathering. Most of these problems can be corrected by …

Thermal Characterization Of Ground And Surface Waters At The Upjohn Company's Portage Road Manufacturing Facility, William K. Hunsberger

Masters Theses

This study focused on thermal characteristics of the ground water and recharged surface water at The Upjohn Company's (now Pharmacia and Upjohn) Portage Road manufacturing facility. Major objectives were: (a) a compilation and graphical evaluation of historical lower aquifer ground water temperatures; (b) estimates of thermal energy introduced into the ground water system through recharge from Upjohn Pond, and predictions of future production well discharge temperatures; (c) an evaluation of hydraulic conductivity related to changes in water density and viscosity influenced by variable temperature; and (d) the stratigraphy beneath Upjohn Pond.

Records reveal increasing ground water temperatures through time in …

Reconstruction Of Wetland Hydrology Dynamics Using Tree Rings, Allan P. Hascall Iii

Dissertations

Increment core samples were collected and examined to test the hypothesis that the history of punctuated or intermediate-term changes in wetland soil-moisture conditions can be reconstructed from the annual growth-ring record of trees. The hypothesis is based on plant physiological principles that indicate a relationship between water surplus stress and impaired physiological activity that could lead to reduced growth.

Sampling sites were selected for their ostensible historic hydrologic variability and the availability of documentation of hydrologic disturbances. A conceptual model was developed by which trees were sampled along a hydrotopographic gradient for comparison of radial stem growth in uplands versus …

A Depositional Analysis Of The Wymer Site, Berrien County, Michigan And Its Relationship To Post-Glacial Lake Levels In The Lake Michigan Basin, Kevin A. Kincare

Masters Theses

The Wymer site is an archeological site on the St. Joseph River floodplain 1.5 miles north of Berrien Springs, Michigan. Early and Middle Archaic cultural phases were found at the site. These sites are unusual in that their occurrence corresponds to low lake levels associated with Lake Chippewa and were assumed to occupy the now submerged shoreline areas.

A site evaluation was undertaken to examine the types of sediments and depositional structures. Trenches, grainsize analysis, ¹⁴C samples and valley topography were used to determine that the site was a point bar situated on a terrace above the modern floodplain. …

The Effects Of The Kalamazoo Station No. 4 On The Nearby Kleinstuck Nature Preserve, Robert J. Buechler

Masters Theses

This was a 15 month study that studied the effects of Kalamazoos' Municipal Pumping Station No. 4 on the Kleinstuck Nature Preserve. The preserve is about a quarter of a mile in the up gradient direction of Station No. 4. This study demonstrates that there is a direct correlation between the pumping and the water levels at the preserve. Pumping records show that there is no correlation between precipitation and the water levels at the preserve.

There are other factors which exaggerate this effect. It has been found that the drain field at the Y.M.C.A. parking lot, the breaching of …

Spatial And Temporal Variability In The Distribution Of Nitrate In An Agriculturally-Impacted Aquifer, Cass County, Michigan, Caroline Lovetere

Masters Theses

Ground-water sampling in a shallow unconfined aquifer within a predominantly agricultural area in southwestern Michigan indicated spatial and temporal variability in the distribution of nitrate. The unconfined aquifer, which is about 40 feet thick, consists of glacially-deposited sand and gravel with interbedded clay lenses and is separated from a lower semi-confined aquifer by a 3-to 26-feet-thick till layer.

The site of the study was a 47-acre agricultural field, characterized by corn and alfalfa hay production, to which hog manure and commercial fertilizers were frequently applied. The shallow water table and relatively permeable glacial sands in the vadose zone combined to …

A Study Of The Chemical And Physical Interactions Between A Wetland And A Shallow Aquifer In Cass County, Michigan, Lisa Marie Anderson

Masters Theses

A study of the ground-water chemistry and flow direction adjacent to a wetland was performed in a major hog producing area. Nested piezometers, consisting of wells 7 to 18 feet deep, were installed around the wetland to determine the vertical distribution of hydraulic head and water-quality parameters. Piezometer elevations were surveyed to determine precise ground-water elevations to delineate the ground-water flow regime around the wetland. Water samples were taken at three different times to analyze water quality and seasonal variations. Analytical parameters included major ions, redox sensitive parameters (DO, nitrate-N, ammonia, iron, and sulfate), and total organic carbon.

An Evaluation Of Methods To Determine The Thickness Of Free Product In A Shallow Water Table Aquifer, Ross B. Wagner

Masters Theses

Estimates of the volume of recoverable free phase petroleum product in soils are frequently based on poorly understood empirical methods. These methods, in the form of field tests and/or equations, require simplifying assumptions and apparent product thickness to calculate the thickness or specific volume of free phase product. The purpose of this study was to compare the available methods against each other to cross validate them.

The field methods evaluated at a well with an apparent product thickness of 1.69 feet were: Yaniga's bailer test, split-spoon soil sampling, a test pit excavation and a new tool developed for direct measurement …

Ground Water Movement Through The Highly-Fractured Crystalline Core Of A Large-Scale, Foreland Uplift, Roy Al Gorge Arch, South-Central Colorado, Timothy L. Clarey

Dissertations

The objectives of this study were twofold: ( 1) to examine the well-exposed, basement core of the Royal Gorge arch as a large-scale, field test of ground water flow through a fractured, crystalline, aquifer system; and (2) to devise a method to more accurately determine the direction of maximum aperture of a fractured aquifer through structural and hydrogeologic analysis.

The recognition of a preferred direction of maximum aperture in a fractured aquifer remains an important hydrogeologic consideration because flow through a fracture is proportional to the cube of the aperture width. Previous studies of hydraulic directions using fracture orientation techniques …

The Effects Of Air Sparging On Aquifer Hydraulic Conductivity, Hans Neve

Masters Theses

Air sparging is a relatively new technology used to remove organic contaminants from aquifers. This remediation technique involves injecting into contaminated portions of water table aquifers. Theoretically air sparging will reduce aquifer hydraulic conductivity. Injected air fills some of the available sediment pores, thus restricting the flow of water to the remaining water-filled pore spaces.

The purpose of this study was to measure the reduction in hydraulic conductivity due to air sparging. This was assessed using both laboratory and field techniques. The hydraulic conductivities of several different sediments were determined in the laboratory using a large constant head permeameter modified …

Evaluation Of Bail-Down Test Methods For Characterizing Free Product Recoverability From An Aquifer, Laura L. Krol

Masters Theses

Determination of the occurrence and recoverability of free product impacting the subsurface environment has been an on-going challenge in the environmental industry. A simple and relatively inexpensive test to perform in the field is the free product bail-down test. Many authors have proposed various analysis methods using these data for the determination of different free product characteristics.

The purpose of this project was to determine the comparability and possible validity of bail-down test interpretation methods for predicting hydrocarbon hydraulic conductivity/transmissivity and true free product thickness. Bail-down test data collected from two sites were analyzed and interpreted using methods from the …

The Variability Of Carbon Dioxide In The Vadose Zone, John J. Ring

Masters Theses

The purpose of this thesis was to observe and attempt to explain the variations of carbon dioxide in the vadose zone of a nature area in southwestern Michigan. Well nests, consisting of discrete soil gas sampling points and temperature probes set at depths ranging from 3 to 53 feet, were constructed in a sandy, glacial outwash plain. Soil samples were collected for analysis of organic carbon content during installation. Soil gas samples were collected periodically from June, 1992 to March, 1993 and analyzed for CO₂ and O₂ concentrations. Occasionally, samples were collected and analyzed for isotopic C^{13 …}

Hydrogeochemical Delineation Of A Groundwater Flow System, Berrien County, Michigan, Patrick J. Bartnik

Masters Theses

The objective of this study was to examine the possibility of determining groundwater flow directions from natural variations in groundwater chemistry. Groundwater samples were analyzed for major cation and anion concentrations. These data were to have been contoured and then compared with groundwater flow maps generated by conventional methods. The purpose was to determine whether a correlation could be drawn between the two methods. However, the results of the study did not allow for this comparison.

The plotted major cation and anion data did not lend themselves to contouring, which suggests that greater control may be required during the selection …

Geophysical Investigation At The Mouth Of The St. Joseph River Valley And Adjacent Lake Michigan Shoreline In St. Joseph And Benton Harbor, Michigan, David L. Seng

Masters Theses

A combination of geophysical methods were employed in an attempt to characterize a small section of the shoreline of the St. Joseph, Michigan, region of the Lake Michigan shoreline. Electrical resistivity and Ground Penetrating Radar profiles conducted along the shoreline and within the nearshore environment reveal a buried valley of the ancestral St. Joseph river. This valley represents incision of the channel during lowered lake levels at the end of the Pleistocene.

Lakeward dipping radar reflectors are identified throughout the study site. Within the buried valley the reflectors are not glacial till as is the case outside the inferred valley …

A Feasibility Study For Using Computerized Water Well Records To Delineate Areas Of Recharge-Discharge Potential, Lauren D. Hughes

Masters Theses

A method for delineating areas of recharge-discharge potential has been developed utilizing computerized water well records. The methodology is based on the vertical head differences found between wells with shallow depths of submergence and those with deeper depths of submergence. The residual values generated represent the magnitude of vertical potential and can be contoured to delineate areas of recharge-discharge potential. Well data were obtained from the Kalamazoo County Groundwater Database. Well selection was based on depth of submergence and total well depth.

The methodology was tested in Texas and Schoolcraft Townships, the Donnell Lake Study Area, and Kalamazoo County. Regularly …

Subsurface Glacial Geology Of The Area Between The Tekonsha And Kalamazoo Moraines, Kalamazoo County, Michigan, Kim Finkbeiner

Masters Theses

Cross sections profiling the stratigraphy of the glacial sediments were created using the geological logs recorded on water well records. Glacial sediments in the study area comprise a large outwash complex between two moraines. The surficial landforms are the result of the last Wisconsinan advance and retreat through the area.

Cross sections contructed for this project reveal at least three major till units. An additional till unit contains a weathered soil sequence. Therefore, it is possible that this paleosol represents the Sangamon Interglacial period between the Wisconsinan and Illinoian stages. No obvious evidence of movement of the Saginaw Lobe remains …
