Assessment Of Atrazine In A Rural Water Source: Rough River Lake, Kentucky, Scotty Sharp
Assessment Of Atrazine In A Rural Water Source: Rough River Lake, Kentucky, Scotty Sharp
Masters Theses & Specialist Projects
Atrazine [2-chloro- 4-(ethylamino)-6-(isopropylamino)-l,3,5-triazine], a widely used herbicide in US corn production, impacts quality of drinking water for many rural water supply systems. Four systems at Rough River Lake, Kentucky, have had high levels of atrazine in raw water and in some cases finished water that have exceeded the legal limit of 3 parts per billion (ppb). The Rough River Lake watershed is 1,700-km2, much of which is located in limestone karst. A hypothesis was developed stating that there would be higher concentrations of atrazine in the northeast section of the Rough River Watershed, located in Hardin County, due to the …
Modeling Soil Erosion In The Upper Green River, Ky, Narcisa Pricope
Modeling Soil Erosion In The Upper Green River, Ky, Narcisa Pricope
Masters Theses & Specialist Projects
Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease in the transport capacity of streams, increase in the risk of flooding, filling reservoirs, and eutrophication. A primary focus in examining the problems associated with soil erosion arid ultimately in proposing control measures should be on identifying the sources of the sediment. Therefore, a model that would be able to assess soil erosion needs to start by identifying the …
The Public Interest Test For Water Appropriations, Sandi Zellmer
The Public Interest Test For Water Appropriations, Sandi Zellmer
Nebraska Water Center: Faculty Publications
Nebraska, like most states, imposes a “public interest” review on applications for water appropriations, changes and transfers. However, Nebraska statutes do not provide any specific public interest criteria for use in evaluating applications for new water appropriations or intra-basin transfers. Under Neb. Rev. Stat. § 46-234, an application for a water appropriation may be refused when denial is demanded by the public interest. The director of the Department of Natural Resources (DNR) has the duty of determining whether the public interest demands the denial of a water appropriation, but is given no express statutory criteria to provide assistance in making …
Instream Flow Legislation, Sandi Zellmer
Instream Flow Legislation, Sandi Zellmer
Nebraska Water Center: Faculty Publications
In the west, state law historically considered water left in the stream to be wasted. Western states, which rely heavily on diversions to meet their water needs, have encouraged full appropriation of rivers and streams. In many cases, however, diversions have resulted in the depletion of stream flow reliant ecosystems and adversely affected fish, wildlife, recreation and river navigation.
A comparison of Nebraska law to the water law of other western states demonstrates that Nebraska’s existing instream flow legislation is quite narrow. Nebraska statutes impose a variety of restrictions on instream flow appropriations, many of which are unique and even …
Water As Property, Sandi Zellmer
Water As Property, Sandi Zellmer
Nebraska Water Center: Faculty Publications
The issue of whether water is or should be characterized as property under the law raises considerable controversy. In the western United States, water is typically viewed as a form of property, while in the east it is not. Whether water should be treated as property has been the subject of an extensive body of scholarship. Proponents argue that establishing legally protected, secure private property rights encourages maximum utilization of resources. Also, exclusivity and surety of possession can foster wise investment of labor and stewardship. Conversely, the absence of legally protected interests in property ownership can result in a “tragedy …
The Republican, The Platte And Pumpkin Creek: Current Nebraska Water Policy Issues, J. David Aiken
The Republican, The Platte And Pumpkin Creek: Current Nebraska Water Policy Issues, J. David Aiken
Nebraska Water Center: Faculty Publications
Potential conflicts between surface water users and ground water users are posing perplexing challenges to Nebraska policy makers. Surface water law is the rule of priority, "first in time is first in right," as administered by the Nebraska Department of Natural Resources (DNR). Ground water is primarily the rule of correlative rights, as administered by local natural resources districts (NRDs). Traditionally ground water irrigators have been subject to few restrictions on drilling new wells or how much water could be used (except in the Upper Republican NRD in southwest Nebraska). Now the DNR can ban new wells in overappropriated and …
A Long-Term Perspective On Drought In The Great Plains And West, Sherilyn C. Fritz
A Long-Term Perspective On Drought In The Great Plains And West, Sherilyn C. Fritz
Nebraska Water Center: Faculty Publications
Management of water resources requires an understanding of the full range of natural variability and its consequences. The weather record, which spans the last 100 years or so, provides a snapshot of the contemporary history of drought and its impacts, but this record is relatively short and is inadequate for understanding long-term trends or for evaluating the magnitude of human impacts. A variety of so-called paleoclimatic records - such as tree rings, lake sediments, and sand dunes - record the history of the environment and can be used to extend the record of climatic variation to older intervals of time. …

Smart Growth
Across New England communities have been experiencing a rapid outward surge of development away from our community and downtown centers. Effects of sprawl include a loss of wildlife habitat, farm and timber lands; increased costs of community services and higher taxes; auto-dependency, longer commutes, and increased congestion; increases in air and water pollution; a sedentary lifestyle and increased obesity; and losses to one’s sense of place and social ties.
State-level responses to sprawl have surfaced throughout New England in recent years. This report describes 11 examples of these responses, representing all six New England states and a diversity of recent …

Occurrence Of Sulfonamide Antimicrobials In Private Water Wells In Washington County, Idaho, Usa, Angela L. Batt, Daniel D. Snow, Diana S. Aga
Nebraska Water Center: Faculty Publications
County (Weiser, Idaho) were collected to assess the impact of a nearby confined animal feeding operation (CAFO) on the quality of the local groundwater. All six samples were found contaminated by two veterinary antimicrobials, sulfamethazine (at concentrations from 0.076 to 0.22 μg/l) and sulfadimethoxine (at concentrations from 0.046 to 0.068 μg/l). These groundwater samples also contained elevated concentrations of nitrate and ammonium. Three of the sampled wells have nitrate levels that exceeded the maximum contaminant level set by the US Environmental Protection Agency for drinking water, with nitrate concentration as high as 39.1 mg/l. All but one well showed nitrate, …

Current Status And 25 Year Trends For Soil Acidity, Fertility And Salinity In The Coastal Catchments Of The Peel-Harvey, Robert Summers, David Weaver
All other publications
The current status and trends of soil analyses in the coastal catchment of the Peel Harvey estuary were developed from historical soil data (1982 to 1991) combined with a renewed sampling to greater depth (1 m). This report encompasses the data collected from the first year of the project. Soil phosphorus content was found to be high but has dropped slightly since 1991. Soil pH is very low and is likely to be limiting production but have risen slightly since 1991. Soil potassium content is generally so low that it may be limiting production especially to the west of the …

Augusta Me: The New Bridge Begets A New Planned Neighborhood, Molly Pulsifer, Richard Barringer
Planning
Construction of a new Third Bridge over the Kennebec River in Augusta offered the prospect of a new and handsome gateway to the city. Further, the resulting change in traffic patterns offered the City the chance to plan for a pattern of development quite different from what the city had experienced for the past half-century. The case study describes the planning and construction of the new bridge and corridors that re-routed traffic out of Augusta’s downtown and older neighborhoods, and created the opportunity for planned development adjacent to the corridor created by the new bridge. It goes on to describe …

Relationships Between Pacific And Atlantic Ocean Sea Surface Temperatures And U.S. Streamflow Variability, Glenn A. Tootle, Thomas C. Piechota
Relationships Between Pacific And Atlantic Ocean Sea Surface Temperatures And U.S. Streamflow Variability, Glenn A. Tootle, Thomas C. Piechota
Civil and Environmental Engineering and Construction Faculty Research
An evaluation of Pacific and Atlantic Ocean sea surface temperatures (SSTs) and continental U.S. streamflow was performed to identify coupled regions of SST and continental U.S. streamflow variability. Both SSTs and streamflow displayed temporal variability when applying the singular value decomposition (SVD) statistical method. Initially, an extended temporal evaluation was performed using the entire period of record (i.e., all years from 1951 to 2002). This was followed by an interdecadal-temporal evaluation for the Pacific (Atlantic) Ocean based on the phase of the Pacific Decadal Oscillation (PDO) (Atlantic Multidecadal Oscillation (AMO)). Finally, an extended temporal evaluation was performed using detrended SST …

Human Development And Resources Use In The Coastal Zone: Influences On Human Health, Robert E. Bowen, Anamarija Frankic, Mary E. Davis
Environmental, Earth, and Ocean Sciences Faculty Publication Series
Coastal watersheds and nearshore marine areas are the most valuable and dynamic places on Earth. Human population growth is great in these regions, which are home to some of the most sensitive habitats in the world. Coastal areas provide more than half of the overall service value derived from the global environment (Costanza et al., 1997). Natural (e.g., hurricanes and tsunamis) and human pressures on this environment require it to constantly adjust. More than any other area, the global coast has defined the progress of human culture and continues to be a singular influence in how humans connect to the …

The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas' Water Quality Assessment report, the Soil Conservation Service River Basin Study, and several University of Arkansas studies. Thirty-seven sub-watersheds have been identified by the SCS in the Arkansas portion of the Illinois River basin. In the Arkansas portion of the Basin, the Illinois River, Evansville Creek, Baron Fork, Cincinnati Creek, Muddy Fork, Moores Creek, Clear Creek, Osage Creek and Flint Creek were all classified as not supporting their designated use as primary contact recreation …
