Remedial Action Plan For The Codisposal And Stabilization Of The Monument Valley And Mexican Hat Uranium Mill Tailings At Mexican Hat, Utah, Uranium Mill Tailings Remedial Action Project Office, Albuquerque Operations Office, Department Of Energy

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

The Mexican Hat tailings site is in the San Juan County, Utah, two road miles southwest of the town of Mexican Hat on the Navajo Reservation. The Navajo community of Halchita is approximately 0.5 mile southwest of the site. The mill at the Mexican Hat site was operated from 1957 to 1965 by Texas-Zinc Minerals Corporation and the Atlas Corporation. Originally, two irregularly shaped tailings piles were located in the northeastern portion of the site. They occupied approximately 69 acres of the 235-acre designated site and contained approximately 2,575,000 cubic yards (cy) of tailings. The total amount of materials, including …

A Thermal Desorption Modulator For Continuous Monitoring Of Volatile Organic Compounds, Yun Chen

Theses

A thermal desorption modulator is made from a short segment of thin tubing containing an adsorbent or a chromatographic stationary phase. A carrier gas containing the analyte is introduced into the analytical column through the modulator which acts as a sample trap. Rapid electrical heating of the modulator releases a "concentration pulse" of the analyte and this serves as an injection similar to that from an injection valve. The modulator also acts as a sample preconcentrator and can be used to make repetitive injections every few seconds. In this research, the mechanism of thermal desorption modulator was studied and was …

Application Of Organophilic Clay, Koshy Koshy

Theses

The overall goal of this project is to asses the feasibility of using clay to filter water contaminated with organic contaminants. The clays that were used were provided by the Union Carbide Corporation and the Industrial Mineral Ventures (IMV), a division of Floridin company. The organic contaminants that this project concentrated on were, naphthalene, 1,4-dioxane, and phenol. The feasibility studies were done by batch isotherm studies. The protocol for the batch studies were the same as the ones used previously for granular activated carbon. This project looked at a total of six Union Carbide clays and five IMV Floridin clays. …

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

Colby College Watershed Study: Salmon Lake and McGrath Pond (2009, 1993)

Salmon Lake has a history of algal blooms which have decreased the recreational and aesthetic value of the lake (Nichols et al. 1984). As early as the 1920’s, Salmon Lake was reported to have poor water quality. Algal blooms were reported throughout the 1970’s. Numerous complaints led to a study in 1975 by the Maine Department of Environmental Protection (MDEP) and another in 1984 by the U.S. Geological Survey to determine the cause of the accelerated algal growth in the ponds. Both studies concluded that the primary cause of these algal blooms was high concentrations of phosphorus in the water. …

Asymmetric Trends Of Daily Maximum And Minimum Temperature, Thomas R. Karl, Philip D. Jones, Richard W. Knight, George Kukla, Neil Plummer, Vyacheslav Razuvayev, Kevin P. Gallo, Janette Lindseay, Robert J. Charlson, Thomas C. Peterson

School of Natural Resources: Faculty Publications

Monthly mean maximum and minimum temperatures for over 50% (10%) of the Northern (Southern) Hemisphere landmass, accounting for 37% of the global landmass, indicate that the rise of the minimum temperature has occurred at a rate three times that of the maximum temperature during the period 1951-90 (0.84°C versus 0.28°C). The decrease of the diumal temperature range is approximately equal to the increase of mean temperature. The asymmetry is detectable in all seasons and in most of the regions studied.

Nonpoint Source Pollution From Agricultural Runoff: An Analysis Of Problems, Solutions, And The Remedial Action Plan Process For The St. Louis River Basin, Thomas V. Giddings

Marine Affairs Theses and Major Papers

Agricultural nonpoint source pollution is the pollution coming from agricultural production, which has no clear origin. It comes from a diffuse source, such as a farm field or an animal holding area. While programs and studies probe every facet of point sources and extol the efforts of point source clean-up, the relatively more difficult task of identifying nonpoint sources and the process of proposing to do something about them has been largely ignored. Reducing the adverse impacts on the environment from farm related activities requires knowledge of the various pollutants and how pollutant pathways can be interrupted. Nutrients, and pesticides …

Chapter 3 will examine the concept and legal requirements of the port State control regime. Chapter 4 will focus on the role of the port State with respect …

User Perceptions Of The Environmental Quality And Governance System Of Narragansett Bay, Mary-Beth Gadzik Hart

Marine Affairs Theses and Major Papers

This paper hypothesizes that there will be differences in perception between the users and managers of Narragansett Bay with respect to (1) the Bay's environmental quality; and (2) the effectiveness of the governance system established to manage and regulate the Bay. Any discrepancies in the perception of the quality of Narragansett Bay's shoreline and water resources among various user groups are likely to contribute to conflicts between users, and a less efficient approach to the management of Bay resources. Thus, the identification of where management policies may diverge from the interests of public user groups will serve to improve resource …

Analysis Of Factors Contributing To Environmental Activism: A Case Study Of Beach Clean-Up Participants, Elizabeth Ann Fuller

Marine Affairs Theses and Major Papers

This study was initiated to investigate factors which contribute to environmental activism. Towards this end, three hypotheses were investigated. First, it was hypothesized that beach clean-up participants would harbor pro-environmental attitudes. Second, it was hypothesized that participants would be relatively young, politically liberal, well-educated, and wealthy. Finally, it was hypothesized that particular types of social structure would influence a person's decision to participate in a beach clean-up. Specifically, it was hypothesized that participants at each clean-up location would be clique members and/or would be structurally equivalent. Surprising, it was revealed that there was virtually no difference in attitude between the …

Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall

Journal of the Department of Agriculture, Western Australia, Series 4

Today in Western Australia, sheep are run at slightly higher stocking rates, are achieving greater lambing percentages (up JO per cent) and higher wool cuts per animal ( up 0. 6 kg greasy) than in the 1960s. When all components of production are considered, the productivity of sheep fanns has increased by 2. 7 per cent per year over the past 35 years.

The challenge of the next decade is to achieve substantially greater rates of improvement than for past years if the sheep and wool industries are to maintain their significant place in Western Australian agriculture.

Field Manual For The Identification Of Selected North American Freshwater Fish By Fillets And Scales, David W. Oates, Lisa M. Krings, Karen L. Ditz

Other Publications in Wildlife Management

This manual is designed for use in the field to help conservation officers identify fish that have been filleted or skinned. Many North American freshwater gamefish and those caught by commercial fishermen are included. Our goal was to collect six fish of each species for measurement purposes. Several states and provinces including Alaska, Colorado, Florida, Idaho, Iowa, Michigan, Missouri, Nebraska, New York, Ontario, Saskatchewan, Texas, Virginia, Washington, Washington D.C., Wisconsin and Wyoming furnished samples. Fish may vary from location to location; these differences were not corrected for in this manual.

For identification of fish, we will first examine fillets. Fish …

Controlling Mountain Beaver Damage In Forest Plantations, David S. De Calesta, Ralph E. Duddles, Michael C. Bondi

Other Publications in Wildlife Management

Damage to conifer regeneration by mountain beavers, more commonly called boomers, results in significant losses in Western Oregon annually. Most of the damage is to 1- to 5-year-old conifer seedlings. Where populations are high, repeated clipping by mountain beavers can cause loss of production through poorly stocked acres-even reforestation failures.

Damage can continue on saplings up to 15 to 20 years old; however, newly planted seedlings are particularly vulnerable. In a few instances, extensive burrowing can undermine the roots of larger trees enough to topple them.

This publication will help you design a program to reduce mountain beaver damage in …

Archeological Investigations At Two Sites In Dinosaur National Monument: 42un1724 And 5mf2645, James A. Truesdale, National Park Service

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

Archeological excavations in Dinosaur National Monument (DINO) were conducted at 5MF2645 (the Pool Creek Site) in 1988 and 42UN1724 (Juniper Ledge Shelter) in 1989. The information from these two sites, along with archeological data obtained between 1988 and 1992, have expanded our knowledge of the past 3700 years of human occupation in the DINO area. Juniper Ledge Shelter is a south-southeast facing rockshelter in the Jones Hole Ely Creek area of the monument. Excavation of a two meter square unit produced evidence of three occupational components and a Fremont burial of an adult female with associated artifacts. The upper two …

Completion Report: Arkansas State Pesticides In Ground Water Monitoring Project, Terry Nichols, Paul Vendrell, Kenneth Steele

Arkansas Water Resources Center Technical Reports

Executive Summary. The Arkansas State Plant Board (ASPB) has completed a monitoring project in Ashley County, Arkansas. Twenty-nine samples from 23 wells were analyzed for 10 pesticides commonly used in Ashley County. The only detection was Metolachlor, at 0. 71 ug/L, in one well. When the well was subsequently resampled no pesticides were detected. Fifteen of the wells were also tested for nitrate. In one of the wells nitrate was measured at 10.3 mg/L. The other wells were all below 0.05 mg/L. Extensive quality assurance (QA) data collected during the project indicate that 94% of the pesticide data meet all …

Woodruff County Groundwater Vulnerability, H. D. Scott

Arkansas Water Resources Center Technical Reports

There is much unknown about the extent of pesticide contamination of groundwater in Arkansas. In recent years, several research studies have been conducted where wells for irrigation and domestic uses have been sampled and analyzed for pesticides (Lavy, 1988; USGS,1993; Nichols, et al., 1993). For state and federal regulatory agencies, evaluation of the potential ground water contamination begins with considering those areas in Arkansas where pesticides are used and where the ground water is vulnerable to contamination. With a relatively large area of crops grown in Arkansas and only limited financial resources available for chemical analyses by state and federal …

Improving Sustainable Production From Water Repellent Sands, Paul Blackwell

Journal of the Department of Agriculture, Western Australia, Series 4

The agricultural management of water repellent ( non-wetting) sands is difficult, and production from them is mostly low. However, there are ways to make them more productive.

Furrow sowing and the incorporation of dispersive clay are two likely methods to make these soils easier to manage, more productive and more profitable than they are now.

This article discusses several aspects of our research on water repellent sands. In addition, some of the costs and benefits of alternative management strategies are outlined.

13.4.8. Options For Water-Level Control In Developed Wetlands, J. R. Kelley Jr., M. K. Laubhan, F. A. Reid, J. S. Wortham, L. H. Fredrickson

Waterfowl Management Handbook

Wetland habitats in the United States currently are lost at a rate of 260,000 acres /year (105,218 ha/year). Consequently, water birds concentrate in fewer and smaller areas. Such concentrations may deplete food supplies and influence behavior, physiology, and survival. Continued losses increase the importance of sound management of the remaining wetlands because water birds depend on them.

Human activities modified the natural hydrology of most remaining wetlands in the conterminous United States, and such hydrologic alterations frequently reduce wetland productivity. The restoration of original wetland functions and productivity often requires the development of water distribution and discharge systems to emulate …

Considerations Of Variations In Ionospheric Field Effects In Mapping Equatorial Lithospheric Magsat Magnetic Anomalies, Dhananjay Ravat, W. J. Hinze

Earth and Environmental Sciences Faculty Publications

Longitudinal, seasonal, and altitude‐dependent variability of magnetic fields is investigated in equatorial latitudes to determine their effect on the isolation of lithospheric Magsat magnetic anomalies. An estimate of ‘ionospheric effect’ was compiled by averaging the total intensity Magsat anomalies as a function of dip latitudes (called ‘dip‐latitude averages’) from dawn and dusk data sets grouped according to longitudes, time (months), and altitudes. Unanticipated seasonal variations were observed in dusk Magsat data over the Indian sector that may contribute to an improved understanding of the equatorial electrojet. The amplitudes of the dawn dip‐latitude averages are small in comparison to the dusk …

Effects Of Moonlight And Daylight On Hydroacoustic Estimates Of Pelagic Fish Abundance, Chris Luecke, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

To determine how moonlight and daylight affect hydroacoustic estimates of fish abundance, we used a dual-beam transducer and echo integration to survey pelagic fish (primarily Bonneville ciscoes Prosopium gemmifer) in Bear Lake, Utah and Idaho. During the new moon, the fish were dispersed (not schooling) below the thermocline, chiefly at the depths of 10–20 m. At full moon, they were dispersed but much closer to the bottom, where they were difficult to detect. Acoustic estimates offish density and biomass during full moons were approximately 50% of values derived during new moons. A diel survey during a new moon indicated that …

Snake River Sockeye Salmon Habitat And Limnological Research, David Teuscher, Doug Taki, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Historically, thousands of Snake River Sockeye salmon returned to the Sawtooth Valley to spawn. Evermann (1896) reported that the Sawtooth Valley Lakes were teeming with red fish. Bjornn (196~) estimated that 4,360 sockeye returned to Redfish Lake in 1955. These numbers no longer exist. In the 1980's, less than 50 Snake River sockeye salmon survived to spawn (Bowler 1990). Since 19-90, only 13 sockeye have returned. Because of recent declines, the Shoshone-Bannock Tribes (SBT) petitioned the National Marine Fisheries Service (NMFS-) to list Snake River sockeye as endangered. As a result, Snake River sockeye were listed and the Bonneville Power …
