EntrapmentMonitoring at an Arctic Seawater Intake
This paper presents the results of a monitoring program designed to quantify the level of fish entrapment during a seawater treatment plant (STP) operation as well as immediate and delayed...
Rediscovery of the Lower Duwamish River Estuary Solutions to Pollution by Point and Nonpoint Source Controls
Beginning in 1960, a series of point-source pollution controls, new sewage interceptors and treatment plant upgrades dramatically improved conventional water quality parameters in the...
Using Multi-Attribute Analysis to Establish Marine Pollution Research Priorities
The paper discusses how techniques like multi-attribute analysis, when used in workshops or surveys, can be most effectively applied to enriching the informational basis for future agency...

Implementation of the International Treaty for the Prevention of Marine Pollution from Ships 1973, as amended by the Protocol Related Thereto, 1978 (MARPOL 73/78) will help to reduce the...
Citizen Education and Participation
The role of public participation is of increasing concern to governmental technicians responsible for the development of comprehensive planning programs in general community planning,...
Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...
Toxicant Reduction in the Dunny Way CSO
Combined sewer overflows (CSO) are a source of pollution to receiving waters and need to be controlled. As an interim approach to improving environmental conditions at this site in Seattle,...
Sewage Trapping by Water Parcels in Puget Sound
Sewage effluent entering Puget Sound, Washington, often becomes trapped in discrete parcels of water. The parcels are easily identifiable in vertical density profiles as layers of well-mixed...
Environmental Impacts from Treated Ballast Water Discharge into Port Valdez, Alaska
A ballast water treatment plant has operated on the south shore of Port Valdez, Alaska since 1977. In recent years the plant processed, on the average, nearly 51,000 m**3 of the ballast...
Modeling Dilution of Wastewater Outfalls in a Tidal Estuary
Field studies and modeling have been conducted to assess initial dilution of wastewater outfalls in Puget Sound, a fjord-like estuary in the State of Washington. Recent numerical dilution...
The Benefit of Utilizing Case Specific Modelling and Data to Determine Effluent Limitations
This abstract refers to the results of a normal conservative approach to a more realistic, substantiated approach to determining effluent limitations. The new approach was used to establish...
Application of an Ecosystem/Water Quality Model as a Tool for Managing Estuarine Water Quality
A laterally averaged two-dimensional computer model was developed to simulate the hydrodynamics, transport, and ecosystem dynamics of Budd Inlet, a small partially mixed estuary located...
Cogenerating Columbia River Salmon and Hydropower
In recent years a number of regional institutional arrangements have been consumated which have potential for reducing overfishing of Columbia River chinook stocks. In the Pacific Northwest...
Athens Siphon and Outfall
More than 130 million gallons of untreated domestic and industrial wastewater are discharged each day into the sea near Athens. To mitigate this situation, the government of Greece is...
Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...
Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...
Reclamation of Athabasca Oil Sand Sludge
The bulk of oil sand tailings (80 to 90%) consists of quartz sand, which is defined to be everything coarser than 44 microns. The other 10 to 20%, termed 'sludge',...
Design and Performance Monitoring of Clay-Lined Landfills
The use of thick clay liners has been applied to Wisconsin landfills for over a decade. Currently, there are over 35 solid waste disposal facilities in Wisconsin which have been constructed...
The Effects of Brine Contamination on the Properties of Fine Grained Soils
Laboratory tests have been performed to investigate the effects of brine contamination on grain size distribution, relative density, liquid and plastic limits, hydraulic conductivity,...
Embankment Over Fly Ash Pond at Portsmouth Power Station
The fly ash and bottom ash sediments from the Portsmouth Power Station in Portsmouth, Virginia were being sluiced into a 39 acre diked ash pond near the plant. The plant was about to convert...
