  • Disposal of sandy pipeline dredge spoils by end dumping

    Creator:
    Pyles, Marvin Russell
    Abstract:
    Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

  • A physical oceanographic study of the nearshore zone at Newport, Oregon

    Creator:
    Keene, Donald Frederick
    Abstract:
    The nearshore zone at Newport, Oregon was studied during the period September, 1968 to August, 1969. Particular emphasis was placed on those physical factors affecting the distribution of pulp mill wastes discharged within the study area (referred to as Yaquina Bight in this thesis). Temperatures and seawater samples were obtained...

    Creator:
    Krzyaniak, Nathan Anthony
    Abstract:
    The Fukushima Daiichi nuclear disaster of 2011 made it apparent that releases of fission products to marine environments is a very real possibility. Additional data on the movement of material through marine environments can be used by radioecology personnel to assist with both ecosystem protection as well as environmental cleanup...

  • Report on a port-based project to reduce marine debris

    Creator:
    Recht, Fran
    Abstract:
    Plastic waste in the oceans is now recognized as a serious threat to marine life and a pollution problem with economic consequences for mariners and coastal states. Annex V of MARPOL, effective December 1988, is an international treaty which prohibits signatory nations from disposing of any plastic material into the...

  • Disposal of municipal wastes on sandy soil : effect on plant nutrient uptake

    Creator:
    Cottrell, Nancy McCombs
    Abstract:
    Solid municipal waste was applied to Sagehill sand at rates of 0, 100, 200, and 400 tons/acre (0, 67, 133, and 267 tons dry matter). Sewage sludge (2% solids) was applied at 55 gallons per ton of solid waste. Hyslop winter wheat was planted as a cover crop in October...

  • Movement of elemental constituents in sagehill loamy sand treated with municipal waste

    Creator:
    Halvorson, Gary Alfred
    Abstract:
    Metropolitan solid wastes and sewage sludges present a serious disposal problem for many communities. To assess the feasibility of disposal or utilization of these waste products on soils, a study was initiated to evaluate plant growth and soil elemental interactions on a loamy fine sand treated with metropolitan waste. Shredded...

    Polson, Richard Lewis
    Abstract:
    Waste products from industry have often been disposed in landfills without regard for any beneficial uses of the product in agricultural production. This research was conducted to determine the effect of a refractory metal processing waste product on (a) soil chemical and physical properties, (b) perennial ryegrass forage quality and...

    Abstract:
    Metropolitan areas today must dispose large volumes of sewage sludge produced during the wastewater treatment process. This research was conducted to study the effect of large applications of municipal sewage sludge on (a) the distribution of N and trace elements (Cd, Cr, Cu, Mn, Ni, Zn) in the soil profile,...

    Abstract:
    Experimental Drainfields: Standard subsurface sewage disposal systems, gravity loaded and 60 cm deep on slopes above 15% did not show signs of effluent surfacing after 14 months of operation. However, subsurface signs of failure were found on both the experimental sites and on older drainfields established in identical soils. Evidence...
