Pumping-Induced Drawdown Of Streams In Proximity To Agricultural Wells, Sara Alina Sternberg
Pumping-Induced Drawdown Of Streams In Proximity To Agricultural Wells, Sara Alina Sternberg
Master of Science in Environmental Sciences and Management Projects
In the context of unprecedented drought and aquifer overdraft in California, understanding surface water and groundwater connectivity have become increasingly important. While there is a clear understanding of how wells induce drawdown in aquifers (Theis, 1935; Hantush, 1965), secondary effects on local streams have not fully been considered. Current mathematical models targeting aquifer drawdown do not address stream drawdown response in aquifer-stream systems with strong connectivity; instead, they assume the stream to be a constant head boundary. In the drought-stricken and summer-dry climate of California, streams often run dry for months out of the year, which is currently not reflected …

Stormwater To Groundwater: How California Can Increase Groundwater Storage And Build Climate Resilience., Emily M. Perales
Master's Projects and Capstones
California is predicted to have more intense and frequent changes in weather patterns within the next 50 years. Historical and current groundwater use for residential and agricultural use is unsustainable and is creating significant deficits in groundwater aquifers throughout the state. To better adapt to potential damages caused by atmospheric rivers, better stormwater management and capture could increase California’s Climate adaptability. This study is focused on the means and methods to capture stormwater and increase groundwater recharge. Nature-based infrastructure (NBI), or Green Infrastructure (GI), has been used in urban areas throughout the country to mitigate harmful stormwater effects by replicating …

Preliminary Results Of Measurements Of Potentially Cancerogenic 1,4-Dioxane In Surface Water Of Twin Lakes Preserve, Wantagh, Ny, Lijo Jose Varghese
Legacy Theses & Dissertations (2009 - 2024)
1,4-dioxane is a volatile organic compound categorized by the United States Environmental Protection agency (EPA, 2017) as a possible human carcinogen potent to cause tumors in humans. Even though this compound poses significant environmental danger when it contaminates water sources, it is surprisingly less studied, and how it behaves in surface water is less understood. The biggest 1,4-dioxane plume in the United States is located in Long Island region of New York. The purpose of this study was to investigate the presence of 1,4-dioxane in surface water and document the influence of existing 1,4-dioxane plume to Twin Lakes Preserve. To …

Daugherty Water for Food Global Institute: Faculty Publications
There is a need to evaluate high surface nitrate concentrations across agricultural watersheds, both spatially and temporally, to increase understanding of source and timing of nitrogen loads in streams and rivers. Bazile Creek is a high-nitrate stream originating in the agriculturally intensive Bazile Groundwater Management Area of Eastern Nebraska, USA. It is a gaining stream that receives groundwater with high nitrate concentrations originating from nonpoint sources. The objective of this study was to determine spatial and temporal variability of baseflow nitrate concentrations in Bazile Creek and its tributaries and to relate this variability to watershed characteristics. Surface-water nitrate samples were …
Use Of Citizen Science In Monitoring Groundwater Quality: A Case Study From Nebraska, Christopher Olson
Use Of Citizen Science In Monitoring Groundwater Quality: A Case Study From Nebraska, Christopher Olson
School of Natural Resources: Dissertations, Theses, and Student Research
Citizen science has a key role in modernizing effective communication between professional scientists and the general public. However, citizen science differs to that of professional science due to equipment and experience and is a topic argued against citizen science. However, technology in water quality testing has developed in simplicity and affordability to a point where high school students, with hands-on training, can collect groundwater samples and test for quality themselves. Nebraska groundwater quality is a critical part of the state and can utilize high school students as citizen scientists for their communities. High school students from rural communities across Nebraska …

Nitrate Dynamics And Source Within Nested Watersheds Of An Agricultural Stream, Nebraska, Usa, Galen Richards
School of Natural Resources: Dissertations, Theses, and Student Research
Nitrate concentrations have been increasing throughout the globe, primarily due to heightened agricultural activity. Nitrate concentrations in Bazile Creek, located in Northeastern Nebraska, have been steadily rising since the early 2000s. Groundwater nitrate concentrations within the Bazile Creek watershed are high (> 10 mg/L nitrate-N), and there is strong connectivity between groundwater and surface water systems. This study aimed to better understand temporal nitrate concentration variability within the watershed through sampling tributaries and the main channel during baseflow conditions. Nitrate source was also investigated though the use of dual δ15N and δ18O nitrate isotopes, with samples …

Promoting The Sustainable Utilization Of Groundwater Resources In Ethiopia Using The Integrated Groundwater Footprint Index, Xinyu Lin
Honors Scholar Theses
The country of Ethiopia is highly vulnerable to human-caused climate change and is already suffering from the effects. The predominately rural population relies heavily on small-scale agriculture, with 78% of households having at least one member engaged in the field, yet staple crops are highly susceptible to droughts and other weather shocks. Total and agricultural GDP growth in the country have been strongly linked to inter-annual rainfall variability, of which Ethiopia has among the highest in sub-Saharan Africa. A decrease in rainfall since the 1970s has been one of the primary causes of low crop yields, and stresses the immediate …
An Analysis Of Groundwater Quality As Sampling Networks Age: The Gaps In Groundwater Monitoring, Angela Leone
An Analysis Of Groundwater Quality As Sampling Networks Age: The Gaps In Groundwater Monitoring, Angela Leone
Undergraduate Distinction Papers
Groundwater management is an important facet of protecting this important resource. One way that we ensure proper groundwater management is through the regular, long-term monitoring of groundwater wells at waste management sites throughout the country. This study investigates potential changes to groundwater quality attributed to degradation of well construction materials rather than impacts to aquifers from wastes. This assessment was completed using a data analysis of groundwater trends at closed landfill sites. An analysis of fifty-five sites was completed and three sites met our criteria for suitable data history. Due to the lack of suitable data, a more thorough investigation …

School of Natural Resources: Faculty Publications
The sustainability of groundwater resources for agricultural and domestic use is dependent on both the groundwater recharge rate and groundwater quality. The main purpose of this study was to improve understanding of the timing, or seasonality, of groundwater recharge through the use of stable isotopes. Based on 659 groundwater samples collected from aquifers underlying Natural Resources Districts in Nebraska, the isotopic composition of groundwater (δ 2H, δ 18O) was compared to that of precipitation by (a) mapping the isotopic composition of groundwater samples and (b) mapping a seasonality index for groundwater. Results suggest that for the majority of the state, …

Risk And Cost Assessment Of Nitrate Contamination In Domestic Wells, Pongpun Juntakut, Erin M.K. Haacker, Daniel D. Snow, Chittaranjan Ray
Daugherty Water for Food Global Institute: Faculty Publications
This study combines empirical predictive and economics models to estimate the cost of remediation for domestic wells exceeding suggested treatment thresholds for nitrates. A multiple logistic regression model predicted the probability of well contamination by nitrate, and a life cycle costing methodology was used to estimate costs of nitrate contamination in groundwater in two areas of Nebraska. In south-central Nebraska, 37% of wells were estimated to be at risk of exceeding a threshold of 7.5 mg/L as N, and 17% were at risk of exceeding 10 mg/L as N, the legal limit for human consumption in the United States. In …
Defining And Addressing Interconnected Goals In Groundwater Management Planning Across The Usa, Allison Gage
Defining And Addressing Interconnected Goals In Groundwater Management Planning Across The Usa, Allison Gage
Masters Theses
Groundwater accounts for approximately 99% of the available freshwater on Earth, and is an important resource for irrigation, potable water, and domestic use in the United States. However, the overuse of groundwater has led to aquifer depletion in several basins across the USA, resulting in storage reduction, contamination, salt water intrusion, and depletion of surface waters. To properly manage groundwater for the future, there is a need for well-informed Groundwater Management Plans (GWMPs) in order to prevent further depletion and erosion of the resource. Previous studies have focused on groundwater management relative to groundwater laws, regulations, and institutional arrangements. This …
Towards Conjunctive Management Of Surface Water And Groundwater In The Mediterranean, Matthew Lagod
Towards Conjunctive Management Of Surface Water And Groundwater In The Mediterranean, Matthew Lagod
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
One of the fundamental principles of integrated water resources management is the interconnected nature of water in the hydrological cycle, including the interactions between surface water and groundwater. Although scientists have long recognized these interactions, in many cases they are not reflected in natural resources policies and management practices. As a result, the allocation of water resources by public authorities may not be optimal, and may furthermore lead to long-term degradation of water resources and the ecosystems they sustain. In response to this and to growing pressure on water resources from increasing human populations, water experts have developed a body …

When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs
When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs
William & Mary Environmental Law and Policy Review
It may seem surprising to see such concern over groundwater usage in a state like Wisconsin. While known for its dairy and cheese production, Wisconsin is first in the nation for producing snap beans and cranberries. Agriculture contributes $88.3 billion annually to Wisconsin’s economy alone. In addition to bordering two of the Great Lakes, Lake Michigan and Lake Superior, Wisconsin boasts that it is home to about 15,000 lakes. And this does not include the numerous rivers and streams throughout the state. These facts alone may make Wisconsin seem an unlikely place for disputes over groundwater, as water seems to …
The Impact Of Land Use On Nitrate-N Movement And Storage In The Vadose Zone Of The Hastings’ Whpa, Craig Adams
The Impact Of Land Use On Nitrate-N Movement And Storage In The Vadose Zone Of The Hastings’ Whpa, Craig Adams
School of Natural Resources: Dissertations, Theses, and Student Research
Nebraska has one of the largest agricultural economies in the United States and relies heavily on irrigation and fertilizer application to maintain crop yields. Over-irrigation and continuous application of nitrogen (N) in many areas has led to accumulation of nitrate-N in soils and sediments throughout the state’s vadose zone. Because nitrate-N is both persistent and mobile, groundwater concentrations in many areas of Nebraska and other agriculturally intensive states are increasing. Nitrate-N contamination of public and private drinking water supplies that utilize groundwater are of particular concern. Vadose zone sampling is an important method for rapidly assessing the effect of changing …
Willingness To Pay For Irrigation Water Under Scarcity Conditions, Tyler Robert Knapp
Willingness To Pay For Irrigation Water Under Scarcity Conditions, Tyler Robert Knapp
Graduate Theses and Dissertations
Reliance of Arkansas agricultural producers on groundwater for irrigation has led to depletion of the Mississippi River Valley alluvial aquifer. Without intervention, consequences include insufficient groundwater to meet irrigation demand as well as drawdown of the deeper Sparta Aquifer, upon which communities in eastern Arkansas rely for non-agricultural use. Among proposed solutions to combat groundwater decline is the construction of off-farm surface water infrastructure to meet the irrigation needs of producers. Despite the importance of irrigated agriculture to Arkansas, there is little know about the economic value of irrigation water to producers. Thus, we implement a double-bounded dichotomous choice contingent …
Water Source Partitioning For Shrubland Transpiration In A Mixed Phreatophytic Plant Community, Amanda Jean Wagner
Water Source Partitioning For Shrubland Transpiration In A Mixed Phreatophytic Plant Community, Amanda Jean Wagner
UNLV Theses, Dissertations, Professional Papers, and Capstones
Groundwater in the basins of east central Nevada (Great Basin Desert, NV) has been permitted for export to southern Nevada. These basins are also vulnerable to changes in climate that could lead to declining recharge. Any decline in groundwater levels no matter the driving force could significantly impact phreatophytes (deep rooted shrubs), which utilize water from both the vadose zone and the capillary fringe to meet plant water needs, to support growth, and for overall health. A reduction in groundwater due to these forces could have a significant impact on the decoupling of phreatophytes from what is normally a reliable …
