Survey Of The Impacts Of Environmental Regulations On State Highway Operations, Theodore Hopwood Ii, Christopher M. Oberst

Kentucky Transportation Center Research Report

In recent years, the transportation industry in Kentucky as represented by Kentuckians for Better Transportation (KBT) and the Kentucky Transportation Cabinet (KyTC), have expressed concern over the growing impact of environmental regulations upon transportation activities in the state. The imposition of environmental regulations has resulted in higher costs for new construction and maintenance on roads, project delays, scheduling and financing difficulties, and the creation of additional transportation agency bureaucracy to address environmental regulation mandates. In Kentucky, the impacts of those regulations have not been thoroughly assessed nor have the attendant costs been measured. Coinciding with that lack of information is …

Vinyl Chloride Biodegradation With Methanotrophic Attached Films, Yarrow M. Nelson, William J. Jewell

Civil and Environmental Engineering

Methanotrophic degradation of vinyl chloride (VC) is investigated using a laboratory-scale methanotrophic attached-film expanded-bed (MAFEB) bioreactor. This study provides a basis for applying a microbial cometabolizing reaction to practical treatment of toxic chlorinated compounds. The MAFEB reactor was operated at 20°C with influent VC concentrations ranging from 1,800 to 9,600 µg/L and bed hydraulic retention times ranging from 3.7 to 7.6 h. VC effluent concentrations during steady continuous operation ranged from 3 to 140 µg/L, with most values less than 26 µg/L, resulting in removal efficiencies of 96.3% to 99.8%. The maximum continuous-flow VC degradation rate observed at 20°C was …

A Refinement Of Risk Analysis Procedures For Trichloroethylene Through The Use Of Monte Carlo Method In Conjunction With Physiologically Based Pharmacokinetic Modeling, William J. Cronin Iv, Eric J. Oswald

Theses and Dissertations

This study refines risk analysis procedures for trichloroethylene (TCE) using a physiologically based pharmacokinetic (PBPK) model in conjunction with the Monte Carlo method. The Monte Carlo method is used to generate random sets of model parameters, based on the mean, variance, and distribution types. The procedure generates a range of exposure values for human excess lifetime cancer risk of lxl0 (exp-6), based on the upper and lower bounds and the mean of a 95% confidence interval. Risk ranges were produced for both ingestion and inhalation exposures. Results are presented in a graphical format to reduce reliance on qualitative discussions of …

Analysis And Development Of An F-5 Pollution Prevention Management Program With Recommendations For Creation Of Similar Programs For Other Aircraft, Janice M. Gavern

Theses and Dissertations

This study developed a pollution prevention program for the F-5 aircraft, and described its utility and applicability as a generic framework for similar programs. A representative set of F-5 technical orders was analyzed by hand, and the identified chemicals, materials, and processes were loaded into a spreadsheet data base for additional analysis. The Environmental Protection Agency EPA 17 chemical list, and lists of ozone depleting chemicals (ODCs) were used as criteria to identify, for minimization, reduction, or elimination from use on the F-5, a hazardous material (hazmat) subset of those chemicals and materials which had already been identified. The identified …

Pollution Prevention Incentives For Major Weapon System Programs, Donna C. Heinz, Dudley C. Wireman

Theses and Dissertations

This research was undertaken to identify positive incentives that would motivate both government personnel and contractors to incorporate pollution prevention into the early design phases of weapon system acquisitions. The adoption and implementation of such incentives would allow the Air Force to reach pollution prevention objectives more efficiently. A literature search revealed little information on the pollution prevention program in the military. In contrast much information was found concerning military cleanup activities. As a result, in-depth personal interviewing was used to measure pollution prevention awareness in Aeronautical Systems Center program offices. Interviews, analysis, and comparisons were made between three groups …

USAF is dedicated to the clean up of past releases of hazardous substances at its bases under the Installation Restoration Program (IRP) . Clean up decisions are based upon data produced from investigations. Large amounts of waste may be derived from investigations. Investigation-derived waste (IDW), especially that with a hazardous component, may pose significant health protection and regulatory compliance problems if neglected. This study identifies the status and the need for improvement of IDW management to avoid those problems. Information on the background of IDW management was collected through a review of environmental laws, waste management regulations, and existing guidance. …

An Analysis Of Site Parameters Affecting Natural Attenuation In Saturated Soil, William H. Potts

Theses and Dissertations

This study investigated the natural attenuation mechanisms and some of the parameters affecting those mechanisms in the saturated zone. A literature search revealed numerous studies of various attenuation and the associated parameters. Much of the literature emphasized biodegradation as the most promising attenuation mechanism. BIOPLUME II(TM), a fate and transport model, was used to simulate the fate and transport of contaminant plume. The effects of the model parameters were investigated by observing the distance a contaminant plume was expected to migrate over a fifty year period. The investigation was limited by the model which excludes chemical reactions and some physical …

Analytical Modeling Of Aquifer Decontamination By Pulsed Pumping When Contaminant Transport Is Affected By Rate-Limited Sorption And Desorption, Thomas A. Adams, Robert C. Viramontes

Theses and Dissertations

This research explores radially convergent contaminated transport in an aquifer towards an extraction well. This thesis presents the equations governing the transport of a contaminant during aquifer remediation by pulsed pumping. Contaminant transport is assumed to be affected by radial advection, dispersion, and sorption/desorption. Sorption is assumed to be either equilibrium or rate-limited, with the rate-limitation described by either a first-order law, or by Fickian diffusion of contaminant through layered, cylindrical, or spherical immobile water regions. The equations are derived using an arbitrary initial distribution of contaminant in both the mobile and immobile regions, and they are analytically solved in …

Development Of A Multicriteria Decision Model For Prioritizing Air Force Environmental Restoration Program Projects, Thomas E. Ellingson, T. G. Gallogly

Theses and Dissertations

Cleaning up hazardous and toxic wastes left from past activities has become one of the major goals of the Department of Defense. Within the Air Force, individual major commands (MAJCOMs) annually review numerous projects submitted under the Defense Environmental Restoration Program (DERP) and forward these projects to HQ USAF/CEVR for funding. Until recently, adequate resources have been available to fully fund all projects. However, within the last two years, funding shortfalls have been experienced, and projects have received only partial funding. The Air Force needs a decision support system that will assist in determining funding priorities for these projects. This …

Capabilities Of Air Force Wastewater Treatment Plants In Complying With Projected Regulatory Requirements, Steven R. Ford

Theses and Dissertations

One of the major environmental regulations that directly affects the Air Force is the Federal Water Pollution Control Act (FWPCA). The 1972 FWPCA amendments set forth a series of national goals regarding water quality. The main mechanism for achieving these goals was the National Pollutant Discharge Elimination System (NPDES). NPDES is a program requiring dischargers to limit the quantity of pollutants discharged into the receiving waters. This research effort predicts changes in future NPDES permit requirements, and evaluated the capabilities of Air Force wastewater treatment plants (WWTPs) in meeting those future requirements. It was found that future permit requirements will …

Economic Analysis Of Costs Incurred From Chemical Exposures In The Workplace Resulting In Non-Carcinogenic Responses As Additional Justification For Pollution Prevention Projects, Michael L. Forcht, Timothy D. Neu

Theses and Dissertations

This research determines the applicability of using costs associated with chemical exposures in the workplace for financial justification of pollution prevention projects. Specifically, this thesis looks at costs incurred due to noncarcinogenic effects caused by chemical exposures. Average costs are determined through researching applicable statistical cost data. Acute effects are analyzed using an analysis of available statistical accident data from multiple sources. Expected values are then calculated based upon the projected cost of an accident and the probability of having an accident. Chronic effects are analyzed using an empirical analysis. A risk assessment is used to determine the likelihood of …

Tillage And Cropping Practice Effects On Furrow Irrigation: Hydraulics And Macroporosity, Martin John Norton

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Furrow irrigation efficiency and performance is greatly influenced by advance time, infiltration and roughness. An experiment was conducted to determine tillage system and cropping system effects on those three variables. Four tillage systems, disk (D), chisel and disk (C), ridge till (RT), and slot plant (SP) were the treatments. They had been continuous for 17 years on a Hasting's silt loam (fine, montmorillonitic, mesic Udic Argistoll) soil. Subtreatments were a corn/soybean rotation (CS) and a continuous corn (CC) cropping system since 1984. A complete block split plot design was used. We measured inflow rate, advance time, runoff, and furrow geometry …

Optimal Contaminant Plume Management With Us/Wells, Alaa H. Aly, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A micro-computer based software package developed at utah State University for computing optimal pumping strategies for well systems (US/WELLS) is demonstrated. US/WELLS is used to determine the optimal time-varying sequence of extraction and injection rates when only limited data is available. The software determines the extraction/injection rates, in pre-specified locations, needed for immobilizing and/or extracting a groundwater contaminant plume. In the optimization problem, the objective function can be either to minimize the extraction/injection rates needed {linear) or to minimize the hydraulic power used for lifting water (quadratic). In either case, different weights can be assigned to emphasize any time period. …

Optimizing Conjunctive Water Use In A Dynamic Stream Aquifer System, Getachew Belaineh, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer systems during a dry season requires using finer discretization in time and space. Presented is a computer model, US/REMAX, developed by Utah State University personnel for aiding best management of stream-aquifer systems for both long and short eras. The model computes strategies for optimally allocating surface and ground water resources in time and space. For a water supply problem the model can maximize the sum of delivered surface and ground water. For an environmental protection …

Leukocyte Extravasation Into The Pancreatic Tissue In Transgenic Mice Expressing Interleukin 10 In The Islets Of Langerhans., Lise Wogensen, Xiaojian Huang, Nora Sarvetnick

Journal Articles: Regenerative Medicine

Transgenic expression of interleukin 10 (IL-10) in the islets of Langerhans leads to a pronounced pancreatic inflammation, without inflammation of the islets of Langerhans and without diabetes. A scattered infiltration of macrophages (M pi) precedes localized accumulations of CD4+ and CD8+ T lymphocytes, B lymphocytes, and M pi. This recruitment of inflammatory cells to the pancreas is somewhat surprising, since the biological activities of IL-10 in vitro indicate that IL-10 is a powerful immunosuppressive cytokine. Since endothelial cells play a major role in leukocyte extravasation, we examined if vascular changes and extralymphoid induction of peripheral and mucosal type vascular addressins …

Light Injection From An Active Cladding To The Core Of A Fiber Optic Fluorosensor, Alvin Leon Bryant

Electrical & Computer Engineering Theses & Dissertations

A fluorosensor works on the basis of light injection from the clad into the core of an optical fiber. The sensitivity of such a sensor depends on the efficiency of light injection. Conditions necessary for a high injection efficiency are experimentally determined. The refractive index difference between the core and the clad,ⁿcore ^-nclad, must be maximized to achieve a high injection efficiency. Since an air clad has the least refractive index, a bare core fiber will have a maximum efficiency. Standard optical fibers used for communication employ a minimum value for ⁿcore ^-nclad, in order …

Optimizing Irrigation Management For Pollution Control And Sustainable Crop Yield, G. R. Musharrafieh, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

We developed a simulation-optimization model which maximizes crop yield while maintaining target salt concentration in the root zone, and/ or preventing salt from leaching to the groundwater. The model performs nonlinear optimization and simulation. Implicit finite difference forms of the nonlinear, transient, unsaturated water flow equation, and the convection-diffusion equation are embedded as constraints. Other constraints include nonlinear functions describing the hydraulic properties of the medium. The objectives of the management model is to develop irrigation strategies which prevent salt leaching to the groundwater when salty irrigation water is used. Five different irrigation strategies are developed for Huntington Research Farm, …

Modified Cover System For Hazardous Waste Landfills In Semi-Arid Areas, S. Dutta

International Conference on Case Histories in Geotechnical Engineering

Flawless installation of conventional clay cover system in semi-arid areas is almost an impossibility. Cracks and microfractures in clay cover system leading to high seepage and plume migration has been experienced by many landfills in semi-arid areas. A modified cover system developed by the author at Tinker Air Force Base, Oklahoma is designed to overcome the leakage effect by using manufactured clay liners in combination with a thin cushion of clay layer. Another major disadvantage of the conventional clay cover system is the mounding effect of the cover system and the resulting capture and conversion of the contiguous clean and …
