Stabilization/Solidification Of Organic Containing Wastes Using Organophilic Clay And Coal Fly Ash, Edith Lagoutte

Theses

The relative merits of eight different coal fly ashes for use in the stabilization/Solidification of a waste containing both heavy metals and pentachlorophenol were investigated. Also studied, was the possible use of either untreated or treated (with hexade-cyl ammonium bromide) clay to enhance the stabilization of the organic. The sample composition was : 62% foundry baghouse dust (or 60% if 2% clay as added to the sample), 4.5% cement, 14% coal fly ash, 19.5% water. Pentachlorophenol was chosen as represen¬tative of the organic contamination. All tests were performed after curing the samples at 22°C, 98% Rh for 28 days. The …

Trends Of Eom, B(A)P, Sulfates, And Nitrates In Air-Borne Particulate Matter In Eleven Proximate Locations In New Jersey During 1988, Sathish Pushpala

Theses

Air-borne particulate matter was collected at eleven proximate locations in New Jersey during the year 1988. Particulate matter was extracted in cyclohexane and acetone to separate non-polar and polar components. Particulate matter was also analyzed for B(a)P, Sulfates and Nitrates.

This report presents the inter-site and intra-site variation of concentrations of pollutants between summer and winter seasons. Levels of B(a)P varied from 0.12 to 0.03 ng/M³ between urban and rural sites. During winter, B(a)P concentrations were 5 times more than summer. Concentrations of Cyc which represent mostly primary pollutants, were found 3 times lower in rural sites. Ace fractions …

A Report On Black-Tailed Prairie Dogs In Nebraska-- Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

Nitrate Concentrations Of Ground Water Northern Madison County, Arkansas, Andrew Y. Austin, Kenneth F. Steele

Technical Reports

The presence of an extensive network of solution channels in the fractured carbonate bedrock and a thin permeable regolith in northwest Arkansas makes aquifers in this region susceptible to contamination. Because of these conditions, there is concern about nitrate contamination of the ground water from land applied animal wastes, commercial fertilizers, rural septic systems and municipal sewage systems. In response to these concerns a survey was conducted of the nitrate concentration in rural water wells in the carbonate aquifers of a 420 mi2 area of northern Madison county during "wet" and "dry" seasons in 1990. Information from well owners, drilling …

Long Term Management Measures For The Cockburn Sound Restricted Entry Fisheries., P. Millington

Fisheries management papers

The objective of this management plan is to introduce rules which will ensure there is a real reduction in professional fishing units and fishing effort in the medium to long term. This reduction should enable a small professional fishery to co-exist with the recreational sector, supply fresh fish to the metropolitan area, ensuring there is no proliferation of "shamateur fishing" and providing a supply of recreational angling bait.

Lake Mead Nutrient Enhancement Project, Peter D. Vaux, Larry J. Paulson, Nevada Department Of Wildlife, National Oceanic And Atmospheric Administration

Publications (WR)

The Lake Mead Fertilization Project is a research program designed to investigate the potential for using large-scale artificial fertilization to enhance the game fisheries of this reservoir through an increase in the population of threadfin shad, the system's primary forage species. A substantial decline in the population of largemouth bass, together with poor condition of adult striped bass, are the two major issues affecting the Lake Mead game fisheries. Both issues have been hypothesized to be a result of an inadequate amount of forage in the reservoir. Previous studies have in turn suggested that a major factor limiting the shad …

Radon Contamination Of Residences In A City Built Upon A Karst Landscape Bowling Green, Warren County, Kentucky, James William Webster

Masters Theses & Specialist Projects

The United States Environmental Protection Agency (EPA) estimates that 8 to 12% of U.S. homes have radon concentrations that equal or exceed 4 picocuries per liter (pCi/l). A statewide screening of Kentucky by EPA resulted in an average residential radon concentration of 2.8 pCi/l with 17% of the homes at or above 4 pCi/l. EPA requires routine monitoring and maintenance or worker health records in mines and caves having radon daughter concentrations at or above 0.30 working levels (WL).

Hydrogeology And Hydrogeochemistry Of The Shallow Alluvial Aquifer Zone, Las Vegas Valley, Nevada, Harry Stephen Wild Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

In Las Vegas Valley, Nevada, the shallow alluvial aquifer zone is a possible source of contamination to the principal alluvial aquifers that provide 30% of the public drinking water supply for the valley. Development of the principal aquifers has lowered pressure head in the principal aquifers and created the potential for downward seepage from the shallow aquifer zone. This study was undertaken to characterize the hydrogeology and hydrogeochemistry of the shallow alluvial aquifer zone and to compare the hydrogeochemistry of the shallow and principal alluvial aquifer zones.

A 37 well shallow ground water monitoring network was established and water-level, water-quality, …

The Pacific/ North American Teleconnection Pattern And United States Climate. Part I: Regional Temperature And Precipitation Associations, Daniel J. Leathers, Brent Yarnal, Michael A. Palecki

School of Natural Resources: Faculty Publications

The Pacific/ North American (PNA) teleconnection index, a measure of the strength and phase of the PNA teleconnection pattern, is related to the variations of the surface climate of the United States from 1947 through 1982 for the autumn, winter, and spring months when the PNA is a main mode of Northern Hemisphere mid-tropospheric variability. The results demonstrate that the PNA index is highly correlated with both regional temperature and precipitation. The strongest, most extensive correlations between the index and temperature are observed in winter, but large areas of the country show important associations during the spring and autumn as …

Each area was advised independently through separate reports and the three reports are collated herein for future reference.

The Impact Of Mining And Mining Exploration On Range Resources And Pastoral Pursuits In The Pilbara, Gascoyne, Murchison And Goldfields Regions Of Western Australia, H J. Pringle, G A. Carter, J L. James, R E Y O'Connor

Resource management technical reports

Mining activity occurs very widely over relatively small areas of the rangelands. However, it is an intense landuse which can create significant offsite effects. Mining activity is most common around metamorphic 'greenstone' belts and broad drainages. Pastoralists reported both benefits and adverse affects as a consequence of mining activity. The main grievances related to unnecessary and excessive disturbance of pastoral land and the failure of operators to inform the pastoralist of their intentions.

Third-Generation Fage Instrument For Tropospheric Hydroxyl Radical Measurement, C. Y. Chan, Thomas M. Hard, A. A. Mehrabzadeh, Robert J. O'Brien

Environmental Science and Management Faculty Publications and Presentations

The authors have constructed a single-stage, frequency-doubled, copper vapor laser-pumped dye laser to be used in the measurement of atmospheric hydroxyl radical concentrations. This laser can be tuned to either the 1← 0 or 0← 0 vibrational transition in the electronic transition ²Sigmalarr²Pi. A new photon counting instrument is used for HO fluorescence detection. Theoretical and experimental studies of instrument performance show better sensitivities and reduced photolytic interferences than have been possible with previous systems based upon Nd:YAG pumping.

Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert

OES Theses and Dissertations

Ground-water-fed interdunal ponds in Nags Head Woods Ecological Preserve lose as much as 7600 m³ yr^-1 of water through evaporation. This withdrawal of groundwater is sufficient to significantly alter flow patterns through the surficial aquifer on Bodie Island, N.C. Statistical analyses of evaporation estimates derived by various methods indicate a weak correlation, (r²=0.4-0.5) between pan evaporation data from Aurora, N.C. and pond evaporation at Nags Head Woods calculated by water budget analyses.

Results of stratigraphic and pedologic analyses in and around the ponds indicate that the ponds formed after development of multiple generations of dunes. This …

The Effects Of Two Polycyclic Aromatic Hydrocarbons Benzo[A]Pyrene And Naphthalene On Reproductive Success Embryological Development Larval Physiology And Mortality Of The Mud Crab Rhithropanopeus Harisii (Gould), Gregory V. White

OES Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAHs) such as naphthalene (Nap) and benzo[a]pyrene (B[a]P) are common in the water column and sediments of estuarine and coastal areas. The mud crab Rhithropanopeus harrisii was exposed to varying concentrations of Nap or B[a]P to determine the effects on reproductive success, embryological development, larval physiology and mortality. Nap and B[a]P decreased hatching success and prolonged embryological development. Both pollutants produced high abnormality frequencies for egg exposed larvae. Molt frequency and respiratory rates of larvae from non-exposed eggs were more chronically affected by these pollutants than were egg exposed larvae. The EC₅₀ concentrations were determined for …
