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 Annex II to Marpol 73/78 and the Impact on Reducing Pollution in the Coastal Zone
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,...
Perceiving Toxic Chemicals in Fishing Environments
The perception of toxic chemicals in the fishing environments by anglers was examined in Kansas and Michigan. The main findings of the study were: 1) There appears to be a small, but significant...
Fish Histopathology and Contamination in California's Channel Islands
Ocean dumping of certain hazardous wastes took place at two dumpsites in the San Pedro Channel of the Southern California Bight from the 1940s through the 1960s. This included some 700...
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...
Quantifying Chemicals in Coastal Environments
Because management and regulation is largely based on numerical chemical data, understanding of the process, products and limitations of environmental chemical analysis is critical for...
Dispersion of Coal Particles at the Sea Floor
Due to coal unloading, certain quantities of this material arrive at the sea floor, and may pollute the beaches. This study provides a theoretical analysis and numerical simulations of...
Territorial Sea Management by the State of Oregon
The institutional capability of the State of Oregon to manage the territorial sea under its jurisdiction recently was examined by the authors. Oil and gas development, marine mineral mining,...
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,...
Waste Disposal Activities and the Protection of Estuaries and Coastal Waters
The disposal of wastes in the Nation's marine environments raises two fundamental issues: first, the general health of the several types of marine waters - estuaries, coastal...
Management Responses to Technical Uncertainty
Recent attention to management and regulation of contaminated waste materials has served to heighten awareness of the role of technical uncertainty in regulatory decisionmaking. Two distinct,...
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...
Drift of Floatable Materials in Puget Sound
Cost-effective methods for predicting the fate of surface borne (floatable) materials and contaminants have been applied successfully within Puget Sound. Several preferred areas for the...
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...
Restoring of Butcher's Slough Estuary?A Case History
A 30-acre parcel of former lumber and plywood mills occupying original estuary and salt marsh wetlands on the northern edge of Humboldt Bay, Humboldt County, north coastal California,...
Vertical Shelter From Hurricanes: Risk Perceptions and Politics
To reduce risks posed by high hurricane evacuation times, vertical shelters have been proposed. This paper presents a preliminary assessment of key decision makers' reactions...
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...
