Comparative Analysis Of Three Remediation Technologies For The Clean Up Of Petroleum Contaminated Groundwater, Thomas Bouck

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper will compare three remediation technologies to determine which is the most efficient and effective remediation treatment for a petroleum contaminated groundwater site. The three remediation technologies are in situ bioremediation, in situ air sparging, and air stripping with carbon filtration. This comparison will be done through a literature review. It will take the information derived from the review and then apply it to the information about a petroleum contaminated groundwater location. The comparative analysis will consist of these parameters permit requirements, clean up time, operating and maintenance, and geological factors.

These factors permit requirements, cleanup time, and operating …

A Buffered Advection/Dispersion Lake Water Quality Transport Framework For Modeling Lake Gaston Pipeline Intake Water Withdrawal, Lloyd Ashton Gatling

Civil & Environmental Engineering Theses & Dissertations

Water quality response to reservoir water withdrawal is investigated in Pea Hill Arm of Lake Gaston, a non-tidal reservoir tributary, where the point of water withdrawal is in an upstream tributary and influences the direction of tributary flow causing longitudinal velocity null flow conditions to occur. The study also focuses on control of withdrawal rate and timing to optimize both quality of water remaining in the tributary and quantity of water that can be safely withdrawn.

Research was conducted assuming steady state conditions and later under spatial and temporal variability experienced in the reservoir with main lake pool elevation fluctuations …

Importance Of Migrating Salmon Smolt In Ring-Billed (Larus Delawarensis) And California Gull (L. Californicus) Diets Near Priest Rapids Dam, Washington, Darryl L. York, John L. Cummings, John E. Steuber, Patricia A. Pochop, Christi A. Yoder

United States Department of Agriculture Wildlife Services: Staff Publications

Ring-billed (Larus delawarensis) and California Gulls (L. californicus) have been implicated in depredations on migrating salmon smolt in the Columbia River. As part of a gull management program conducted in 1995 and 1996, we collected L. delawarensis (n = 120) and L. californicus (n = 45) near Priest Rapids Dam, Washington, and analyzed stomach contents to determine food habits and thus the importance of fish in gull diets. Percent volume measurements and index of relative importance rankings suggested a greater reliance on fish by L. californicus than by L. delawarensis. Peak percent consumption of fish by …

Movements And Distribution Of Radio-Collared Canada Geese In Anchorage, Alaska, Darryl York, John Cummings, Kate Wedemeyer

United States Department of Agriculture Wildlife Services: Staff Publications

We monitored radio-equipped (n = 50) and neck-collared (n = 205) lesser Canada geese (Branta canadensis parvipes) during August through October 1996 in Anchorage, Alaska, to ascertain local patterns of movement and post-molt dispersal; to identify geese from molting sites that frequent Elmendorf Air Force Base (EAFB); and to evaluate the effectiveness of hazing at EAFB. Telemetry data and visual observations of collared geese indicated 59% of geese observed at EAFB were from molting sites ≤10 km from EAFB. We observed 93 marked geese from 11 molting sites 1 or more times in the EAFB airdrome, and 63% …

Estimates Of Radionuclide Loading To Cochiti Lake From Los Alamos Canyon Using Manual And Automated Sampling, Christopher T. Mclean

Water Resources Professional Project Reports

Los Alamos National Laboratory has a long-standing program of sampling storm water runoff inside the Laboratory boundaries. In 1995, the Laboratory started collecting the samples using automated storm water sampling stations; prior to this time the samples were collected manually. The Laboratory has also been periodically collecting sediment samples from Cochiti Lake. This paper presents the data for Pu-238 and Pu-239 bound to the sediments for Los Alamos Canyon storm water runoff and compares the sampling types by mass loading and as a percentage of the sediment deposition to Cochiti Lake.

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 …

An Interpretation Of Martian Thermospheric Waves Based On Analysis Of A General Circulation Model, Manoj Joshi, Jeffery Hollingsworth, Robert Haberle, Alison Bridger

Faculty Publications, Meteorology and Climate Science

Planetary‐scale longitudinal variations in density observed by the Mars Global Surveyor accelerometer in the 125 km region can be qualitatively reproduced by the NASA Ames Mars general circulation model in the 80 km altitude region, but only when locations having specific local times are used in the analysis. If the model results are averaged over all local times, the high‐altitude longitudinal variations nearly disappear, leaving only a small stationary wave 1 pattern, consistent with theory and previous modeling studies. This analysis suggests that the observed wavelike structures are a result of sampling tidal modes at a limited range of local …

Ecology (Re)Defined, Mary Rowland

United States Bureau of Land Management: Staff Publications

This slender, well-written volume is a compendium of terms, 60 altogether, purportedly intended to introduce the layperson to the discipline of ecology. With encyclopedic listings from "Air" to "Zoos," we learn that potential effects of global warming include the spread of malaria and other tropical diseases to previously uninfected areas, and that the world's six billion humans consume 40% of the planet's photosynthetic output. It is clear from the first entry that the book is as much an environmental primer as a science-based one. For example, we read under the topic "Air" that "We should not continue human activities that …

Modeling The Effect Of Nonlinear And Rate-Limited Sorption On The Natural Attenuation Of Chlorinated Ethenes, Peter P. Feng

Theses and Dissertations

Chlorinated solvents like tetrachloroethene (PCE) and trichloroethene (TCE) are the most common detected groundwater contaminants at Department of Defense installations in the United States. Unfortunately, technologies conventionally used to remediate chlorinated solvent-contaminated groundwater often fall short of achieving regulatory goals. Natural attenuation of chlorinated solvents offers an alternative remediation strategy that may achieve goals. However, the processes involved with natural attenuation are not fully understood, and this lack of understanding has hindered acceptance of natural attenuation by regulatory agencies. This study involved use of a numerical model that incorporated the physical, chemical, and biological processes thought to be relevant to …

In Situ Treatment Of Chlorinated Ethene-Contaminated Groundwater Using Horizontal Flow Treatment Wells, Derek R. Ferland

Theses and Dissertations

The limitations of conventional containment technologies for groundwater contaminated with chlorinated solvents have motivated development of innovative technologies to achieve national groundwater remediation objectives. One inn9vative technology that is currently under development involves metal reductants or catalysts to chemically destroy the dissolved chlorinated solvent. Models are important tools that can be used to help transition this technology to the field. Model studies can be used to gain understanding about the technology, help determine when the prospective technology might work for a given site, and design full-scale field applications.

Chromium Concentration Bias In The Particle Size Distribution Of Primer Overspray, Joseph M. Fox

Theses and Dissertations

Air Force aircraft-painting operations create clouds of paint overspray that contain strontium chromate, a confirmed carcinogen, which poses an exposure hazard to painters. It is often assumed that all particles in paint overspray have the same chemical composition as the original paint mixture, however differences in composition may occur in various particle sizes. Because particle size affects where in the respiratory system a particle deposits, actual exposures to a specific chemical may vary. Paint particles greater than 2.5 µm are deposited in the upper respiratory system and will be eliminated by physiological removal mechanisms. Particles less than 2.5 µm will …
