Benefits of Highway Safety Improvement Programs
Even at the most conservative estimate of 2% annual growth in travel, the U.S. would experience almost 58,000 deaths in the year 2000 at a death rate of 2.5 per 100 million miles traveled....
Jet Grouting: The Pace Quickens
Over the past year, use of jet grouting in the U.S. has nearly quadrupled. A versatile tool, it has performed well in settings as diverse as a railway tunnel, industrial waste site and...
Performance of an Artesian Glacial Drift Aquifer with Induced Recharge
The City of Kalamazoo, Michigan, has constructed induced recharge facilities at sites of several of its twenty-one well fields as part of a program for supplying potable water to Kalamazoo...
Evaluating Potential Artificial Recharge Projects
The success of an artificial recharge project can be directly tied to the quality of planning of the potential projects and/or sites. The paper's purpose is to identify the...
Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
Monitoring for Hazardous Waste Leaks
It is safer and cheaper to keep hazardous wastes out of the groundwater and the ground than to remove them. But better monitoring will be required. In this three-part article, the first...
Courting Public Opinion
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted, neighboring communities should be advised of the proposed...
Jet Fuel from the Ground Up
The Port Authority of New York and New Jersey has implemented a multi-million dollar clean up effort to remove oil lenses beneath the bulk fuel farms it maintains at three New York area...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Probabilistic Site Strategy for Transmission Lines
A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model...
Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...
Drilled Piers in the Piedmont?Minimizing Contractor-Engineer-Owner Conflicts
Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are...
Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...
Survey of Groundwater Contamination in Massachusetts
Public water supplies in Massachusetts have been contaminated or threatened from a number of sources. The purpose of this paper is to outline the nature of groundwater contamination and...
A Call for New Directions in Drilling and Sampling Monitoring Wells
The hollow-stem auger drilling technique has an inherent limitation of disturbing large volumes of subsurface materials around the borehole, thereby possibly affecting local permeabilities...
Control of Groundwater Contamination: Case Studies
Engineered solutions to groundwater contamination problems are being proposed at many hazardous waste sites, yet the effectiveness and long-term reliability of many of these proposed solutions...
Emergency Response
A spill normally has five phases; namely, the initial emergency response, the site assessment, the development of a remedial action plan, the implementation of the remedial action plan,...
When to Remediate: Remediation or Reparations
The 1986 reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) forcefully stated Congress' desire to see our nations hazardous...
Physical and Chemical Treatment of Contaminated Groundwater at Hazardous Waste Sites
In selecting an appropriate groundwater treatment system, three steps are normally followed. 1. A groundwater investigation is performed to determine the types and concentrations of contaminants...
The Impacts of CERCLA, RCRA and State Programs on Site Remediation: A Case Study
The major federal programs requiring ground water remedial response actions include RCRA and CERCLA. On the state level New Jersey law makers have enacted a number of statutes which regulate...
