Carbon Cycling And Critical Zone Dynamics In An Urbanized Karst Groundwater System, Amy Hourigan
Carbon Cycling And Critical Zone Dynamics In An Urbanized Karst Groundwater System, Amy Hourigan
Masters Theses & Specialist Projects
Increasing atmospheric CO2 concentrations are correlated to rising global temperatures. Investigating the cumulative global carbon cycling processes is important to understand and quantify the global carbon cycle. By investigating basic geochemical parameters, EpCO2, DIC, and δ13CDIC, at four sites along Lost River Cave (LRC), in Bowling Green, Kentucky, concentrations, fluxes and sources of C dissolved in groundwater were determined. Urban karst groundwater systems, compared to more natural karst landscapes, typically exhibit widespread impervious, heat-absorbing surfaces, urban heat island effects, and increased anthropogenic groundwater inputs and localized CO2 emissions. Carbonate hydrogeochemical …

Climate Change Impacts On Groundwater In Mapc Communities, Jayne F. Knott, Paul Kirshen, Ellen Douglas
School for the Environment Publications
Groundwater is important for human health and the environment but has often been overlooked in the development of climate change adaptation strategies. This is because groundwater is rarely visible, and because changes in groundwater levels are not as dramatic as extreme flooding events, coastal storms, and storm surge. The importance of groundwater for drinking water, natural resources, and streamflow is well documented. Groundwater levels are also important considerations in the design of pavements, underground infrastructure, foundations, on-site wastewater treatment systems, and in the remediation of hazardous waste disposal areas. Groundwater is especially important in the wet northeast, where groundwater levels …

Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown
Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown
Honors Projects
Three different stable isotopes of water occur in nature, with the majority of water on Earth containing the oxygen isotope 16O. These isotopes have slightly differing physical and chemical properties. H2O with heavier oxygen isotopes should theoretically precipitate earlier than lighter isotope H2O, meaning this natural process should allow for the observation of the magnitude of effects of lake-effect precipitation on the basis of water isotope differences. Furthermore, it may allow for better understanding of the significance lake-effect precipitation plays in recharging shallow aquifers. In this study, patterns of lake-effect precipitation from Lake Michigan were observed in a collection of …

Nm Stat § 7-36-20: Disconnected Land And Water Policy In A Climate-Altered Peri-Urban Fringe, Annalise Porter
Water Resources Professional Project Reports
New Mexico (NM) passed a land use law in 1967 that offers tax subsidies to agricultural landowners and is implemented at the county level. This law illustrates a stark disconnect between land and water policy: there are water policy implications because of it, but it has never been discussed accordingly. With a focus on New Mexico’s primary urban county, this study estimates that in 2020, Rio Grande surface flows were used to irrigate 4,388 acres of Bernalillo County land that received the special tax valuation offered through the law. This represents a potential use of nearly 11,000 acre-feet of water, …
Groundwater Modeling Of The West Plains, Wa, Erin L. Toulou, Chad Pritchard Phd, Lauren Stachowiak Phd
Groundwater Modeling Of The West Plains, Wa, Erin L. Toulou, Chad Pritchard Phd, Lauren Stachowiak Phd
2022 Symposium
Located in Eastern Washington in the West Plains Region sits a plateau of Columbia River Basalts between Deep Creek, Hangman Creek, and south of the Spokane River. Primarily in Airway Heights, the amount of drinking water as well as the quality of the water has affected residents in the area. The most recent issue is PFAS contamination, which is thought to negatively affect human health and is found in drinking water wells across the West Plains. We can interpret subsurface geology using new well logs from Fairchild Air Force Base and in the Palisades area. When using ArcGIS PRO, well …

Arsenic (As) is a highly toxic, carcinogenic trace metal that can potentially contaminate groundwater sources in volcanic regions. This study provides the first comparative documentation of As concentrations in groundwater in a volcano-sedimentary region in the Philippines. Matched, repeated As measurements and physico-chemical analyses were performed in 26 individual wells from 11 municipalities and city in Batangas province from July 2020 to November 2021. Using the electrothermal atomic absorption spectrometric method, analysis of the wells revealed that in 2020, 23 out of 26 (88.46%) had As levels above the WHO limit of >10 ppb while 20 out of 26 wells …

Changes in climate and water demand in densely populated regions increasingly affect hydrological systems, and, in turn, impact socioeconomic conditions. In this case study, we identify how the hydrogeological frameworks of two water resource management units, Tietê-Jacaré (TJ) and Piracicaba-Capivari-Jundiaí (PCJ) in Sao Paulo state (Brazil), control the baseflow processes and resilience in the face of streamflow fluctuations in response to anthropogenic activities and climate variation. The results reveal between 40% and 75% contributions of baseflow to total streamflow in basins overlying crystalline and sedimentary aquifers. The basins in PCJ which mostly overly crystalline aquifers, have shorter water residence times …

School of Natural Resources: Faculty Publications
This chapter describes the locally driven, but centrally coordinated, water governance model in Nebraska, U.S. It offers a snapshot of water resources and the importance of agriculture, then moves to the relevant political institutions in the state, and federal controls related to water quantity. The focus of the chapter is on the Nebraska Department of Natural Resources’ (NeDNR) and Natural Resources Districts’ (NRDs) management of surface and groundwater, which has some distinct and some overlapping authority. The main area of overlap is in addressing the connection between ground and surface water, particularly in situations when either or both are over …

The cyanobacterium Trichodesmium plays an essential role supporting ocean productivity by relieving nitrogen limitation via dinitrogen (N-2) fixation. The two common Trichodesmium clades, T. erythraeum and T. thiebautii, are both observed in waters along the West Florida Shelf (WFS). We hypothesized that these taxa occupy distinct realized niches, where T. thiebautii is the more oceanic clade. Samples for DNA and water chemistry analyses were collected on three separate WFS expeditions (2015, 2018, and 2019) spanning multiple seasons; abundances of the single copy housekeeping gene rnpB from both clades were enumerated via quantitative PCR. We conducted a suite of statistical …

Arsenic occurs in the natural environment in four oxidation states: As(V), As(III), As(0) and As(−III). The behavior of arsenic species changes depending on the biotic or abiotic conditions in water. In groundwater, arsenic is predominantly present as As(III) and As(V), with a minor amount of methyl and dimethyl arsenic compounds being reported. Global intake of As(III) and As(V) via drinking water and food has dramatically increased in recent years. The commonly used term inorganic arsenic includes both As(III) and As(V) species and constitutes the highest toxicological risk associated with arsenic in water compared to the organic arsenic species. Inorganic arsenic …
