Superfund Record Of Decision: Monticello Mill Tailings (Doe), Ut First Remedial Action, U.S. Environmental Protection Agency, Office Of Emergency And Remedial Response
All U.S. Government Documents (Utah Regional Depository)
The 300-acre Monticello Mill Tailings site is comprised of a 7S-acre inactive uranium and vanadium milling operation and affected peripheral properties in Monticello, San Juan County, Utah. Surrounding land use is rural residential and agricultural. The site overlies a shallow alluvial aquifer, and part of the site lies within the floodplain of Montezuma Creek. Approximately IS-acres of wetlands adjacent to Montezuma Creek also have been contaminated by tailings. In 1940, the site was operated as a vanadium ore-buying station. Milling of ore began in 1942, and a vanadium/uranium sludge product was produced onsite from 1943 to 1944. Onsite uranium milling …
Factors Affecting Wood Fuel Consumption And Environmental Impacts In Warren County, Kentucky, Barry Vann
Factors Affecting Wood Fuel Consumption And Environmental Impacts In Warren County, Kentucky, Barry Vann
Masters Theses & Specialist Projects
The purpose of this research is to identify factors that contribute to wood fuel consumption as a space heating source and estimate a county-wide proportion for wood fuel consuming households. In addition, environmental problems associated with deforestation such as erosion and loss of wildlife habitat are delineated; moreover, air pollution resulting from wood fuel emissions are discussed.
An exhaustive literature review provided the basis for the study. Data on Warren County wood fuel consumption patterns were derived from a mail survey. Proportion estimates were tested by using a classical two-tail test of hypothesis. Subsequently, factors were identified and used in …
Metal Speciation And Immobilization Reactions Affecting The True Efficiency Of Artificial Wetlands To Treat Acid Mine Drainage, Anastasios D. Karathanasis, Y. L. Thompson
Metal Speciation And Immobilization Reactions Affecting The True Efficiency Of Artificial Wetlands To Treat Acid Mine Drainage, Anastasios D. Karathanasis, Y. L. Thompson
KWRRI Research Reports
The ability of constructed wetlands to lower total metal concentrations and organically complex metals in acid mine drainage (AMD) was investigated under greenhouse and field conditions. In the greenhouse study, Typha plants grown in six different substrates received simulated acid mine drainage of low metal load for five months. Most effluents, especially those from ground flows, showed significant decreases in acidity and metal concentrations. The pine needle and hay substrates most effectively reduced acidity and total Al levels. Effluents from these substrates contained 80% less total Al than respective influents. Organically complexed Al levels were independent of matrix and varied …

Modeling Mass Transport In Aquifers: The Distributed Source Problem, Sergio E. Serrano
Modeling Mass Transport In Aquifers: The Distributed Source Problem, Sergio E. Serrano
KWRRI Research Reports
This report presents a new methodology to model the time and space evolution of groundwater variables in a system of aquifers when certain components of the model, such as the geohydrologic information, the boundary conditions, the magnitude and variability of the sources or physical parameters are uncertain and defined in stochastic terms. This facilitates a more realistic statistical representation of groundwater flow and groundwater pollution forecasting for either the saturated or the unsaturated zone. The method is based on applications of modern mathematics to the solution of the resulting stochastic transport equations. This procedure exhibits considerable advantages over the existing …

Effects Of Aromatic Concentration On Methane Fermentation, Yi-Tin Wang, Pin-Chieh Pai, H. David Gabbard
KWRRI Research Reports
The anaerobic biodegradability and toxicity of fourteen aromatic compounds were evaluated over a wide range of concentrations using a serum bottle technique. Benzene, toluene, and all three isomers of xylene were not significantly degraded to methane in a phenol-enriched culture. Complete degradation of 1000 mg/L phenol, 800 mg/L catechol, 100 mg/L 2-NP, 100 mg/L 3- NP, and 100 mg/L 4-NP was observed within two months while depletion of 100 mg/L resorcinol and 1000 mg/L hydroquinone required more than six and eight months incubation, respectively. None of the three isomers of chlorophenol were degraded in the phenol-enriched culture. Batch toxicity assay …

The Hydrogeology And Leachate Generation Of An Alum Sludge Lagoon Chesapeake Virginia, Charles M. Darling
The Hydrogeology And Leachate Generation Of An Alum Sludge Lagoon Chesapeake Virginia, Charles M. Darling
OES Theses and Dissertations
In 1986 the City of Chesapeake, Virginia began to dig shallow ponds ("lagoons") to contain alum sludge, a waste generated by the City from the process of treating potable water. Borings at the disposal site reveal that the near-surface geologic units include a thin mud-rich facies which overlies a thick sandy facies, both of which are in the Lynnhaven Member of the Tabb Formation. At 7 meters depth, a clay-rich facies of the Yorktown Formation (Morgarts Beach Member?) underlies the sandy water table aquifer. Water levels from twenty observation wells and two monitoring wells installed into the water table aquifer …

From every side we hear of new threats to our water supply. Carcinogens, droughts, dam failures, global warming, hazardous wastes, deforestation, overpopulation, liability, and an aging infrastructure become household fears; this list grows longer and more foreboding to the average citizen. Some of these threats are real, while others are imaginary. Some we know how to overcome and others we can find ways to overcome, yet, for some, we are still helpless. The strength of a university lies in its success in stimulating inquisitive minds in critical examination of the problems of the world. People sense hope as experts find …

Bulletin No 4174 - Tree Planting On Farms In High Rainfall Areas, Ken Angell
Bulletins 4000 -
Many of the techniques described in this Bulletin are applicable to broadacre farms. However, they are specifically directed to small rural properties in the high rainfall areas.
Trees can usually serve more than one purpose on small rural properties. They can be used as ornamentals, to provide shelter and shade, for erosion control, as a wildlife habitat, or for waterlogging and salinity control.

The Daytime Wind In Valleys Adjacent To The Great Salt Lake, G. L. Stone, D. Hoard
All U.S. Government Documents (Utah Regional Depository)
In 1986 Los Alamos National Laboratory was engaged by the US Army to study the meteorological aspects of emergency preparedness at several sites where toxic materials are stored and handled. The project included a series of tracer and meteorological field experiments in the vicinity of the Tooele Army Depot, 60 km southwest of Salt Lake City, Utah. These experiments generated a large data set for validating numerical simulations and for empiracal analyses of the local meteorology. This paper discusses the main characteristics of the daytime, up-valley flow at the Utah site, including frequency of occurrence, horizontal and vertical structure, and …
