A Decision Model For Environmental Assessment Of Process Waste Products, Kyle F. Byard

Theses and Dissertations

Environmental managers must compare the potential impacts of waste products when deciding upon courses of action. The estimation and comparison of these impacts is a subjective process, and few methods of comprehensive, quantitative comparison of waste products currently exist. The intent of this study is to develop a decision methodology to evaluate the environmental impacts of waste products and to score them for comparison. The method will follow established system design principles and incorporate significant characteristics of the waste material. Scores derived to represent the environmental impacts of materials will then he analyzed employing statistical and probabilistic methods to assess …

Identification And Conservation Strategy For Sandhills Fens In Cherry County Nebraska, Gerry Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

In the Sandhills, fens are generally found in two locations: in stream valleys often near the headwaters and at the upper end of Sandhills lakes and marshes. In both areas groundwater discharge into the valleys can be abundant, and in some cases, has led to the development of fens on the valley floor. A few Sandhills fens approach 500 ac (200 ha) in size and are among the largest fens in the Great Plains. Most Sandhills fens are smaller, some only a few acres (ha) or less in size.

Human disturbances including ditching, artificial flooding, annual haying, overgrazing, invasion of …

Water Resources Studies Along The Arkansas-Oklahoma Border, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

The watershed approach to water resource issues recently has been re-discovered. Scientists and managers recognize the need to consider the entire watershed when delineating and solving today's water resource problems. A simple example is the effect that streams have on the ultimate "health" of a reservoir. Although technically the term watershed should be used only in reference to surface water, the importance of ground water is included in the watershed approach to problems. In recognition that we all "live upstream and downstream," the Arkansas Water Resources Center and the Oklahoma Water Resources Institute sponsored a conference titled "Water Resource Studies …

Passageway Around The Redlands Diversion Dam And Interim Agreement To Provide Water For Endangered Fish, Bureau Of Reclamation, Fish And Wildlife Service, U.S. Department Of The Interior

All U.S. Government Documents (Utah Regional Depository)

This draft environmental assessment (EA) discusses two related actions proposed to assist in the recovery of two Federally-listed endangered fish species. The actions are intended to restore use of historic and designated critical habitat of the Gunnison River by the Colorado squawfish and razorback sucker. The proposed actions are to: construct and operate a fish passageway around the Redlands Diversion Dam; and execute an interim (short-term) memorandum of agreement (water agreement) to supply streamflows needed to operate the passageway and maintain downstream fish habitat and access for fish to the passageway. The EA is prepared jointly by the Bureau of …

Dispersal Dynamics Of The Bivalve Gemma Gemma In A Patchy Environment, John A. Commito, Carol A. Currier, Laura R. Kane, Kathleen A. Reinsel, Irene M. Ulm

Environmental Studies Faculty Publications

The purpose of this study was to analyze the dispersal dynamics of the ovoviviparous bivalve Gemma gemma (hereafter referred to as Gemma) in an environment disturbed by the pit-digging activities of horseshoe crabs, Limulus polyphemus. Gemma broods its young and has no planktonic larval stage, so all dispersal is the result of juvenile and adult movement. Animal movement was measured using natural crab pits, hand-dug simulated crab pits, and cylindrical bottom traps in the intertidal zone at Tom's Cove, Virginia, USA.

This study demonstrated that horseshoe crabs create localized patches with reduced densities of Gemma, that all sizes and ages …

Section I: Thermodynamic Properties Of Hydrocarbon Radicals, Peroxy Hydrocarbon And Peroxy Chlorohydrocarbon Molecules And Radicals Section Ii: Kinetics And Reaction Mechanisms For : (1) Chloroform Pyrolysis And Oxidation (2) Benzene And Toluene Oxidation Under Atmospheric Conditions, Tsan-Horng Lay

Dissertations

Alkyl radicals are important active intermediates in gas phase photochemistry and combustion reaction systems. With the exception of a limited number of the most elementary radicals, accurate thermodynamic properties of alkyl radicals are either not available or only rough estimations exist. An H atom Bond Increment approach is developed and a data base [sic] is derived, for accurately estimating thermodynamic properties (ΔH_f°₂₉₈, S°₂₉₈ and Cp(T)) for generic classes of hydrocarbon radical species.

Reactions of alkyl radicals with molecular oxygen are one of the major reaction paths for these radicals in atmospheric photochemistry, oxidation of hydrocarbon …

Bioremediation Of 2-Chlorophenol In A Laboratory Soil Column, Timothy A. Coon

Theses

In-situ bioremediation offers the prospect of rendering organic contaminants harmless without having to remove them from the subsurface. It involves the modification of environmental factors to stimulate the biodegradation of chemicals in the subsurface by microorganisms. However, for the cost-effective use of in-situ bioremediation, it is necessary to develop accurate engineering models to quantify biodegradation.

In this thesis, the biodegradation of 2-chlorophenol in a laboratory soil column was examined in order to experimentally verify an engineering model. Experiments were performed to obtain the physical and biological parameters required by the model, and the steady-state 2-chlorophenol distribution in the column.

Abundance Of Gulls And Other Birds At Landfills In Northern Ohio, Jerrold L. Belant, Thomas W. Seamans, Steven W. Gabrey, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

We estimated the abundance of birds at three landfills in northern Ohio from May 1991-July 1992 recording 699,350 individuals of 42 species. Gulls (Larus spp.) comprised 94.5% of the birds recorded followed by European starlings (Sturnus vulgaris, 5.0%) and turkey vultures (Cathartes aura, 0.3%). Gulls were primarily of two species, ring-billed (L. delawarensis, 74.49%) and herring (L. argentatus, 25.50%). The mean number of gulls per observation during July-January was at least five times the mean number observed during other months. The combined monthly mean number of gulls at the three landfills peaked in August (>4000 birds), with gulls virtually …

Land Use Patterns In Relation To Lake Water Quality In The Long Pond, South Basin Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: Long Pond, South (2007, 1995)

Long Pond, South Basin receives nutrient inputs from a variety of sources, including roads, construction projects, logging practices, and human waste from subsurface waste disposal systems. If any of these sources are near tributaries or the shoreline, the nutrients can be easily transported into the lake itself. The lake is also used recreationally for boating, fishing and swimming, and is utilized as a source of drinking water for seasonal shoreline residences. The watershed contains the Mt. Vernon and Belgrade transfer stations, and the dump has been capped at each of these stations.

Historically, Long Pond, South Basin has not suffered …

Wetlands/Groundwater Quality In Agricultural Landscapes, D. H. Rickerl, D. E. Kringen, T. A. Machacek

Journal of the Minnesota Academy of Science

In the Prairie Pothole Region (PPR - SO, NO, MN, IA), wetlands classified as "semi-permanent" or "seasonal" can act as groundwater recharge sites. The nutrient filtering capacity of wetlands has been investigated for both natural and constructed wetlands linked to surface water, but there is little information available on their subsequent impact on groundwater quality. This study investigates four seasonal and two semi-permanent wetlands in the PPR of eastern South Dakota. Transitional no-till (TNT) and organic farm (ORG) management systems border the wetlands. The objective is to determine the effects of farm management system on wetland surface water and groundwater …

Chemical And Biological Monitoring Of A Constructed Wetland On Jones Branch Treating Acid Mine Drainage, Barbara A. Ramey, George Chalfant, Jon A. Walker

KWRRI Research Reports

Acid mine drainage (AMD) from an abandoned underground coal mine in the Jones Branch watershed in McCreary County, KY, substantially reduced water quality in Jones Branch. Downstream from the mine seeps, the pH was routinely below 4.5 and concentrations of most heavy metals, especially iron, were elevated. A cattail wetland (1,022 m²) was constructed on Jones Branch in 1988-1989 to obviate the effects of the AMD. Monthly chemical monitoring was performed on the water from above, from below, from the inlet and outlet of the wetland, and from the 25 cells within the wetland. Based on chemical monitoring, …

An Assessment Of The Safety Of Navigation: The Malaysian Perspective In The Straits Of Malacca, Amir Bin Murad

Marine Affairs Theses and Major Papers

The traffic movements in the Straits of Malacca (SOM) have been ever increasing over the past few years resulting in numerous marine casualties that have caused serious concern to the Government of Malaysia. Current characteristics of navigation in the SOM present a potential major catastrophe. The first hypothesis is that there is a positive relationship between traffic movement and the number of marine casualties. Thus, an increase in traffic movement will result in an increased risk of marine casualties. The second hypothesis is that the Traffic Separation Scheme (TSS) did not change the overall trend of marine casualties that occurred …

The Rhode Island Marine Fisheries Council: Stewardship In Need Of Goals And Objectives, Robert Censabella
