Ogallala Aquifer, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The Ogallala Aquifer, or High Plains Aquifer, is a porous body of complex sediments and sedimentary rock formations that conducts groundwater and yields significant quantities of water to wells and springs. The principal sediments and rocks of the aquifer range in age from 33 million years old to sediments being deposited today, but the majority is less than 12 million-years old. Much of the aquifer is composed of the Ogallala Group or Formation. The dominant sediments in the Ogallala and the other hydrogeologic units in the aquifer are riverand wind-deposited sands. The aquifer underlies about 174,000 square miles of the …

Property Planning Manual For The Swan-Canning Catchment - February 2002, Catherine Nind, Kylie Banfield, Brian Lloyd

Farm Systems and Economics published reports

Perth, its suburbs and adjacent semi rural and rural areas are part of the Swan-Canning catchment. Ona broad scale the Swan and Canning Rivers are part of a large drainage system that collects and drains water from across the catchment via a myriad of small channels, creeks, brooks and drains which, working together, concentrates the flow into a single water body, the Swan-Canning Estuary. This drainage system collects water both from the surface of the land and also from water, which seeps beneath the surface and moves underground.

The water may contain a considerable variety of potential pollutants, such as …

Transport Of The Herbicide Atrazine On Suspended Sediments During A Spring Storm Event In Mammoth Cave, Kentucky, Michael Anderson

Masters Theses & Specialist Projects

This study examines the transport of atrazine, an herbicide used in Kentucky to control grassy and broad-leaf weeds in corn fields, on suspended sediments. Atrazine is a known carcinogen and endocrine disruptor and has been shown to be toxic at low environmental concentrations. Atrazine has the capacity to adsorb to soil particles, which in karst areas such as those found in south central Kentucky can be transported directly into the groundwater. Suspended sediments and water were collected from a well at the Hawkins River in Mammoth Cave National Park during a spring storm and tested for atrazine. Atrazine was found …

Dye Tracing To Delineate Drainage Basins And Determine Groundwater Sensitivity, Mammoth Cave, Kentucky; With Special Reference To Potential Groundwater Contamination From Spills Along Interstate I-65, Arthur Capps

Masters Theses & Specialist Projects

The Mammoth Cave System of south central Kentucky encompasses more than 560 km of surveyed cave passages. The largest groundwater basin (244 km2) found within this cave system emerges from the Turnhole Bend Spring on the Green River. During high flow conditions, water from this groundwater basin will spill over into the Echo River section of the cave. Previous research, including cave mapping and dye tracing (Quinlan and Ray, 1989; Currens and Ray, 1998; Coons, 1994), has delineated the boundaries of spring groundwater basins for numerous springs along the Green and Barren Rivers. These data showed that 60% of the …

Dynamic Fluvial Systems And Gravel Progradation In The Himalayan Foreland, Nicholas Brozovic, Douglas W. Burbank

Daugherty Water for Food Global Institute: Faculty Publications

Although the large-scale stratigraphy of many terrestrial foreland basins is punctuated by major episodes of gravel progradation, the relationships of such facies to hinterland tectonism and climate change are often unclear. Structural reentrants provide windows into older and more proximal parts of the foreland than are usually exposed, and thus provide key insights to earlier phases of foreland evolution. Our magnetostratigraphic studies show that, although the major lithofacies preserved within the Himachal Pradesh structural reentrant in northwestern India resemble Neogene facies in Pakistan, they have a much greater temporal and spatial variability. From 11.5 to 7 Ma, major facies boundaries …

The Use Of Spectrofluorimetry And Capillary Electrophoresis/Laser-Induced Fluorescence For The Detection Of Fluorescent Dyes In Groundwater Migration Studies, Patrick Ferguson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis involves work that was accomplished during a two-year internship at the Environmental Protection Agency's (EPA), Environmental Chemistry Branch. The research is an application of trace level determination of fluorescein dyes used as groundwater tracers. The work was performed to determine whether groundwater could migrate from a Resource Conservation Recovery Act (RCRA) site to an adjacent Superfund site. The research involved using Spectrofluorimetry and a new technique called capillary electrophoresis/laser induced fluorescence (CE/LIF) to determine tracer dyes that were injected at the RCRA site and monitored at the Superfund site. Results from Spectrofluorimetry were compared to those of CE/LIF. …

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard

Masters Theses & Specialist Projects

The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …

The Use Of Bauxite Residue As A Soil Amendment In The Peel-Harvey Coastal Plain Catchment - Report On Results Of 1995 Environmental Monitoring Program, Mark Rivers

Natural resources published reports

This report was submitted in accordance with the recommendations of the Environmental Protection Authority (EPA) who have stated that a monitoring program shall be undertaken by Agriculture Western Australia within six months of the widespread use of bauxite residue as a soil amendment. Although this widespread use of bauxite residue has not yet formally commenced, pre-emptive monitoring has been undertaken in order to gain some understanding of the general environmental characteristics of the Peel-Harvey catchment and, in particular, the characteristics and quality of the water flowing through the catchment.

It represents the second annual report submitted to the EPA describing …

Bulletin 4329 - Environmental Hazards Of Farming In Western Australia, Greg Hamilton, Ian Foster, Philip M. Goulding

Bulletins 4000 -

This Bulletin is one of a series on crop establishment practices which minimise soil disturbance and improve stubble retention. In partnership with primary producers, Agriculture Western Australia 1s focussed on improved and profitable farming which conserves or improves the quality of the State's soil resources.

Agricultural land in Western Australia is naturally fragile and susceptible to degradation. Salinity and wind erosion are the most visible and significant forms of degradation, but all forms are present over large areas of agricultural land (House of Representatives Enquiry into Land Degradation in Western Australia, 1988).

The fragility of Western Australia's soils has been …

Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed

Journal of the Department of Agriculture, Western Australia, Series 4

Remnant vegetation, wetlands and riverine systems on both private and public land throughout south-western Australia are being rapidly degraded by dryland salinity, inundation, silting, nutrient enrichment and weed invasion. Richard George, Don McFarlane and Russel Speed outline some of the reasons why this is happening and provide some case studies that highlight actions to protect these remnants.

Agenda: Water Organizations In A Changing West, University Of Colorado Boulder. Natural Resources Law Center

Water Organizations in a Changing West (Summer Conference, June 14-16)

Conference organizers, faculty and/or moderators included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches and James N. Corbridge, Jr.

Water organizations in the western United States range from small, traditional acequia associations to large metropolitan water suppliers. What do these vastly different kinds of organizations have in common? All are feeling the pressures of change in the region--growing urban populations, environmental concerns, and calls for public participation.

This year's summer program will examine how water organizations are adapting to these pressures for change. Speakers drawn from urban, agricultural, and community organizations will share their experiences …

Chloroform Contamination In The Louisville Aquifer: An Investigation Of Its Occurrence And Propagation, Sergio E. Serrano

KWRRI Research Reports

This report presents the main results of an investigation on the nature and propagation of an accidental spill of chloroform in the Louisville aquifer, Kentucky. Much of the effort is concentrated on the development of mathematical models to either reconstruct the history of evolution of the plume, or forecast its propagation in the future. Chloroform is a dense halogenated solvent which exhibits a special migration pattern in porous media: Because of this and the relative absence of a conceptual theory on its hydrodynamics in porous media, meaningful predictive models will have to deal with many unresolved theoretical aspects of contaminant …
