Adsorption Of Sulfur Dioxide On Douglas Fir Woodchips, Uen-Ping David Wang

Dissertations and Theses

In recent years, people have raised their alertness to the hazard of air pollution. Sulfur dioxide is one of the most dangerous chemical compounds among those air pollutants. A study on removing sulfur dioxide from an air stream by adsorption using wood chips as the adsorbent is presented in this thesis. The reason for using wood as an adsorbent is that wood is a porous material and possesses a large surface of cell cavities which can hold a great amount of moisture. As sulfur dioxide gas is passed through the wood bed, it would be either condensed in the cell …

Report On Water Pollution Problems In Las Vegas Wash And Las Vegas Bay, Environmental Protection Agency

Publications (WR)

This report was prepared by the Federal Water- Quality Administration, Pacific Southwest Region, now the Environmental Protection Agency (EPA), Region IX, at the request of the State of Nevada, Department of Health, Welfare, and rehabilitation. In a letter, dated December 5, 1969, this agency asked for technical assistance, as authorized by the Federal Water Pollution Control Act, in developing discharge standards appropriate for Las Vegas Bay, Lake Mead, and the Lower Colorado River. The subsequent study was performed by EPA from January through August, 1970. The establishment of Nevada State Water Quality Standards for these waters will enable responsible officials …

A Study Of Phytoplankton Dynamics In Lake Fayetteville As A Means Of Assessing Water Quality, Richard L. Meyer

Technical Reports

Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow. Its source is groundwater seepage through a calcareous substrate with little contribution from the limited drainage basin. Phytoplankton community development with its associations and assemblages, chlorophylls -a, -b and c, and biomass distribution are described. The seasonal cycles of the chemical parameters NH4-N, NO2-N, NO3-N, ortho-phosphate, silicon, pH, HCO3- and total-alkalinity plus oxygen are described and discussed. The physical parameters of temperature, light and climate are included. The interaction of …

Interim Report On Water Quality Investigation Degray Reservoir, Arkansas, J. Nix

Technical Reports

Impoundment of the Caddo River near Arkadelphia, Arkansas began in August, 1969. Detailed patterns of the dissolved oxygen distribution in this reservoir are presented for the period September, 1969 through April, 1971. Although the reservoir had not reached normal pool elevation, thermal stratification accompanied by severe hypolimnic oxygen depletion has been observed. The dissolved oxygen data show that an under flow occurs in the fall of the year and carries dissolved oxygen into the hypolimnic zone. The gradients of dissolved oxygen concentration observed during the winter indicate that the reservoir does not undergo complete mixing. A short summary of the …

The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher

Theses and Major Papers

It is difficult at best to evaluate the biological and chemical damages of oil pollution, but the physical effects are graphically evident in the blackened beaches and coastlines around the world and in the floating "tar-balls" found in mid-ocean. It is this dramatically visible effect that has stirred public concern. Thus, prevention of such damage is high on the list of priorities for both national and international concern. In the face of the ever increasing potential for pollution, President Nixon has pledged that federal agencies will take the lead in pollution abatement programs.

The Role Of Compulsory Sealanes In Resolving Multiple-Use Conflict On The Continental Shelf, Alfred P. Manning

Theses and Major Papers

An analysis of the nature of multiple-use conflict on the continental shelf developed with particular emphasis on the involvement of ocean transportation and offshore oil recovery. The wide-ranging effects which offshore marine accidents may have on coastal residents is discussed. Trends indicate a growth in the level of conflict stemming from competition between those wishing to use the same ocean space for the same purpose, the same ocean space for different purposes, and different but related ocean space for incompatible purposes. Ocean transportation is identified as the single common element in all three conflict categories. Restriction on traditional concepts of …

Oceanic Disposal Of Radioactive Wastes: Effects And Proposals, Billy M. Ervin

Theses and Major Papers

An investigation of the effects of radioactive waste disposal into the oceans pursued by an examination of the hazards involved, the present sources of radioactive wastes and future prospects. The longevity of many radioactive elements, coupled with the awesome consequences to which even a slight miscalculation may lead, are convincing arguments for the most conservative approach to the problem of disposal of radioactive wastes. Present day disposal of radioactive wastes in the oceans, while significant, have not yet had major discernible effects on man or marine life. However, with the worldwide explosion of electrical power demand and the increasing use …

A Conceptual Draft Of A Dynamic Hydro-Biological Model For Lake Mead, L. G. Everett, Bureau Of Reclamation

Publications (WR)

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show:

(1) the biological relationships in an aquatic system

(2) the role of nutrients in the biological cycle

(3) the role of abiotic factors in a limnetic environment

(4) the status of the art of "Eutrophication modeling".

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker

Technical Reports

Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Environmental Changes Produced By Cold-Water Outlets From Three Arkansas Reservoirs, Carl E. Hoffman, Raj V. Kilambi

Technical Reports

Water qualities of two natural streams (Buffalo and Kings Rivers), one new coId-tailwater (Beaver), and two old coId-tailwaters (Norfork and Bull Shoals) in northwestern Arkansas were studied from July 1965 through October 1968. The essential difference between the old cold-tailwaters and natural streams is a change in water quality which allows the development of a new productive ecological environment. Features which typify the old tailwaters are as follows: (1) relatively homioithermal temperatures; (2) stream beds scoured by strong hydoelectric power generation currents; (3) abundant phytoplankton and benthic macroinvertebrates; and (4) absence of warm water game fishes. Environmental factors characterizing natural …

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system.

The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

The Effect Of Las Vegas Wash Effluent Upon The Water Quality In Lake Mead, D. A. Hoffman, P. R. Tramutt, F. C. Heller, Bureau Of Reclamation

Publications (WR)

This study developed from observations made during an earlier study on Lake Mead which was reported in CHE-70, Water Quality Study of Lake Mead. Results from that study indicated that poor-quality water was flowing into the Las Vegas Bay reach of Boulder Basin, Lake Mead. Also reports of deteriorating water quality, resulting in taste and odors in domestic water supplies taken from Boulder Basin as well as a reduction in the attractiveness of Las Vegas Bay for recreational uses caused by aquatic plants and algae blooms, indicated a need for a concentrated study concerning the effects of flows from Las …

Recent Sediments Of Humboldt Bay, Eureka, California, Robert Wayne Thompson

Special Collections Archived Publications

Humboldt Bay is a coastal lagoon, 14 mi. long and a maximum of 4 mi. wide. The bay has three distinct segments, South, Entrance, and Arcata Bays, each of which occupies the seaward end of one or more stream valleys cut into Plio- Pleistocene paralic sediments. The segments are linked by narrow tidal channels which are bounded by a barrier spit on the west and by high valley interfluves on the east. Climate of the area is rainy temperate . Tides are of the mixed type with a mean range of 6.5 ft.
