Masters Theses

"Onyx Spring, Boiling Spring, Yelton Spring, Wilkins Spring, Hudgens Spring, and Natural Spring are located on public land in Pulaski and Phelps County, Missouri. They were selected randomly to determine groundwater movement and compare water chemistry from the springs that are connected.

Using a dye tracing method, we were able to determine the direction of groundwater flow and a water multiparameter sonde was used to characterize the water chemistry at each point of the springs. As a result, from the six springs studied only three springs are connected which are Yelton, Onyx and Boiling Spring. Regarding to water chemistry this …

Estimating Aquifer System Storage Loss With Water Levels, Pumping And Insar Data In The Parowan Valley, Utah, Ryan G. Smith, Jiawei Li, Katherine R. Grote, Jim Butler

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

In the Parowan Valley of Utah, Groundwater Levels Have Declined by as Much as 30 M over the Past 50 Years with Accompanying Subsidence Rates of Up to 5 Cm/year. Traditional Methods to Estimate Groundwater Storage Change Use a Combination of Groundwater Level and Storativity Estimates, But There is Often Considerable Uncertainty in These. in This Study, We Demonstrate a New Method that Relies on a Combination of Geodetic Data from InSAR, as Well as Groundwater Level and Pumping Data, to Estimate Both the Total Groundwater Storage Loss and the Percentages of Storage Loss in Fine- and Coarse-Grained Layers within …

Analyzing Spatio-Temporal Mechanisms Of Land Subsidence In The Parowan Valley, Utah, Usa, Jiawei Li, Ryan G. Smith, Katherine R. Grote

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Parowan Valley, Utah (USA), is an agricultural region experiencing rapid subsidence due to extensive groundwater extraction from aquifers with a significant portion of fine-grained sediments. To analyze the subsidence spatio-temporally, time-series Interferometric Synthetic Aperture Radar (InSAR) of 155 Sentinel-1 C-band scenes were processed. These data showed approximately 30 cm of ground subsidence in Parowan Valley from 2014 to 2020. Because of the high temporal sampling rate of the Sentinel-1 satellite (12-day cycle), it is possible to determine the seasonal changes of ground deformation and relate this to groundwater extraction. To better understand the relationship between ground deformation and groundwater extraction …

Fate And Transport Of Toxoplasma Gondii Oocysts In Saturated Porous Media: Effects Of Electrolytes And Natural Organic Matter, Christian Pullano

All Theses

Toxoplasma gondii is a pathogenic microorganism that is currently a threat to public health. Understanding the fate and transport of T. gondii through the soil and groundwater is vital in determining the risk it poses to water resources and human health. The physico-chemical interactions between the groundwater and the bio colloid within an aquifer will dictate its mobility and its ability to infect humans. This research examines how various naturally occurring groundwater chemistries containing organic compounds and monovalent and divalent salt solutions will alter the fate and transport of T. gondii. Solutions containing various concentrations of humic acid, fulvic …

Hydrologic Response Of Headwater Streams Restored With Beaver Dam Analogue Structures, Evan Norman

Graduate Theses & Non-Theses

In the semiarid and arid western United States, it is important to understand the potential effects of stream restoration on surface-water and groundwater. In this study, we evaluate the seasonal and annual hydrologic impacts of beaver-dam analogue (BDA) restoration in the Blacktail Creek (BTC) Watershed south of Butte, Montana. We monitored surface water flow, groundwater levels, temperature, and specific conductance primarily using a control-treatment study design. In treated reaches, groundwater levels were closer to the ground surface and showed less seasonal fluctuation. Changes in overall streamflow in the control reaches had stream losses and gains varying from -21.0 to 19.9 …

The Overexploitation Of The Valle De Querétaro Aquifer And Its Impact In Small Peri-Urban Communities, Querétaro, México, Kelsey Kirkland

Dissertations, Master's Theses and Master's Reports

The Valle de Querétaro Aquifer is the only viable local water source satisfying the domestic, agricultural, and industrial water needs of the Querétaro Valley. Severe depletion of the groundwater source has had significant consequences throughout the region, especially in the peri-urban communities of Santo Niño de Praga, Tlacote el Bajo, and La Palma. Historically, residents depended on aquifer-fed freshwater springs (known as Los Tajos) to meet their basic and productive needs. Spring production ceased between 10 and 15 ago and investigating the causes formed the basis of this research.

Analysis of available qualitative and quantitative data was used to identify …

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler

Public Land & Resources Law Review

In Hawai’i Wildlife Fund v. County of Maui, the Ninth Circuit held that the plain language of the Clean Water Act provides jurisdiction over indirect discharges of pollutants from a point source into groundwater that is shown to be connected to navigable waters. The court found that studies confirmed pollutants entering the Pacific Ocean were fairly traceable to the County of Maui’s sewage disposal wells. In affirming the district court’s ruling, the Ninth Circuit held that Maui County violated the Clean Water Act by discharging pollutants into a navigable water without the required permit. The court also concluded the …

Characterizing Long-Term Groundwater Conditions And Lithology For The Design Of Large-Scale Borehole Heat Exchangers, David Charles Smith

Doctoral Dissertations

"Construction of large scale ground coupled heat pump (GCHP) systems that operate with hundreds or even thousands of boreholes for the borehole heat exchangers (BHE) has increased in recent years with many coming on line in the past 10 years. Many large institutions are constructing these systems because of their ability to store energy in the subsurface for indoor cooling during the warm summer months and extract that energy for heating during the cool winter months.

Despite the increase in GCHP system systems constructed, there have been few long term studies on how these large systems interact with the subsurface. …
