This proceedings was presented at the Environmental Engineering 1990 Specialty Conference sponsored by the Environmental Engineering Division of the American Society of Civil Engineers...
Waste Containment Systems
Construction, Regulation, and Performance
This proceedings consists of papers presented at a symposium on waste containment systems at the ASCE Convention in San Francisco, California on November 6th and 7th, 1990. Geotechnical...
Some Design Considerations During Construction
Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...
Coal Gas Legacy
The remains of a former coal gasiication plant were uncovered during redevelopment of a site for the new City Hall in Waterloo, Ont. The coal tar waste was a dense, immiscible tarry fluid...
What's Wrong With Superfund
In nine years of the federal government's Superfund program, $4 billion has been spent and only 38 of the 1,175 sites on the national priority list have been cleaned. There...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Fast Tracking Military Waste
The installation restoration program, the military version of Superfund, helped fast track the cleanup contracts for four military hazwaste sites located at Hanscom Air Field, Bedford,...
The Saga of Senate Bill 2067
With the advent of the California Superfund program, liability related to toxic waste cleanup became a critical issue in California. The state had no authority to indemnify consultants...
The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...
Robotic Roundup
Robots are finding their way on to the construction site. Years of research and development have yielded unmanned machines that complete tasks as mundane as spotwelding and as dangerous...
High Hopes for Cattails
As other areas of wastewater treatment go high tech, man-made wetlands are treating wastewater from small towns and coal mines. Plants are grown in about 1 ft of water. Suspended solids...
State-of-the-Practice Mitigation Measures for Collapsible Soil Sites
Mitigative alternatives for collapsible soil sites are reviewed considering shallow, as well as deep, collapsible soil deposits. In the case of deep soil deposits the overburden pressures...
Characterization of a Site Underlain by Deep Collapsing Soils
The geomorphic setting of a site underlain by an 80 ft (24 m) deep deposit of collapsing silty sand is described. The field and laboratory investigation completed to characterize the geotechnical...
Jet Grouting for Underpinning and Excavation Support
Jet Grouting as a new tool for underpinning and excavation support is presented, describing the systems of Jet Grouting and its advantages over conventional underpinning techniques. A...
Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...
Coastal Barrier Island Management in Florida
Coastal barriers in Florida have experienced the brunt of the state's rapid population growth. Excessive development of these environmentally sensitive areas has destroyed...
Dredge Disposal Monitoring by Fourier Shape Analysis
Fourier grain-shape analysis characterizes a population of sediments in terms of the shapes of the grains. The technique of grain-shape analysis has been successfully applied to the area...
Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
The Brazilian Nuclear Program comprises the Angra I Nuclear Power Plant, in operational tests; the Angra II Nuclear Power Plant, under construction, expected to be completed in 1992; and...
Environment Exploitation by Prehistorical Population of Rio De Janeiro
The specific purpose of this project was to establish the cultural contexts in the area being studied as well as to define the mechanisms of environmental manipulation that were employed...
