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...
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,...
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...
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...
Innovations in Dredged Material Disposal in Puget Sound
This study, known as the Puget Sound Dredged Disposal Analysis (PSDDA), is building on a strong history of federal/state cooperation within Washington which is unique in the United States....
Aquatic Dredged Material Disposal in New England
The Disposal Area Monitoring System (DAMOS) is a large multi-disciplinary environmental monitoring program instituted by the New England Division (NED) of the U. S. Army Corps of Engineers...
Use of Sediment Bulk Chemistry Data for Dredged Disposal Management in Puget Sound
Although no fully scientific approach for setting and interpreting sediment chemical levels is currently available, an effects-based approach for using bulk chemistry data was evaluated...
Protocol for Deep Ocean Disposal Monitoring
Deep ocean sites are presently being considered for the permanent disposal of wastes. The Environmental Protection Agency (EPA), in conjunction with other agencies, is mandated to monitor...
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...
Design of Waste Containment Structures
Synthetic liners, also known as flexible membrane liners (FMLs), have been used increasingly since the early 1970s to contain chemical and hazardous wastes because of their low permeability...
Earthen Liners for Land Disposal Facilities
Proper construction of compacted earthen liners requires special attention to construction details and quality assurance. Moisture content and weight of roller are probably the two most...
Site Characterization for Waste Disposal
Site selection is one of the key decisions in waste management. Site selection involves a conflict analysis which considers various engineering factors including geotechnical, as well...
Design of Geosynthetic Systems for Waste Disposal
Geosynthetic materials (consisting of geotextiles, geomembranes, geogrids and geocomposites) are currently being used in large amounts to contain solid wastes in landfills, surface impoundments...
Chemical Effects on Clay Hydraulic Conductivity
Hydraulic conductivity and its susceptibility to changes with time or exposure to chemicals are major factors in selection of clay for use in waste containment barriers. Available concepts...
