The Metropolitan Boston Area Earthquake Loss Study
This study develops an inventory of critical facilities in the Metropolitan Boston area and analyzes the impact of a project earthquake (Cape Ann Event) on their structural integrity and...

Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...

Endangerment Assessment in a Multilayered Aquifer Using a Microcomputer Based Transport Model
An endangerment assessment describes the types and degrees of potential hazards to public health, welfare, or the environment that may result from the release of hazardous substances into...

Practice of Risk Analysis in the Private Sector
Although risk-analysis is currently gaining acceptance in the decision process among engineers involved in public safety of water resources projects, the 'state-of-the-art'...

Constructing a Better Environment
The civil engineer is traditionally designated the jobsite environmental engineer during construction, and is responsible for managing environmental protection and monitoring. Jobsite...

Housing and Hazardous Waste Contamination
Problems and Remedies
When hazardous waste sites are discovered in close proximity to residential areas, scientists and engineers are often faced with conducting complex studies involving many government agencies...

Management Lessons from Engineering Failures
Engineering failures are not always catastrophic. More are due to improper management of contracts rather than actual physical failures. Some result in loss of life; most result in disputes...

Defining the Infrastructure Problem?The Local View
The Governor's report defines infrastructure as 'the collective network of physical facilities and their maintenance necessary to sustain economic growth and...

Infrastructure: Rehabilitation or New
Basically, each public entity needs to inventory its infrastructure system and evaluate its importance to the immediate requirements of public health, safety and welfare. Prioritize the...

Trouble in Our Own Back Yard
One million tanks will leak toxic and hazardous substances into the U.S. soil within the next four years. Prevention begins with rapid discovery and probability analysis. Various cleanup...

Oilspill Response Technology for the Arctic
Alaska Clean Seas is a spill response organization whose area of interest includes all of the marine environment surrounding Alaska. It provides support to members in contingency planning,...

Arctic Oil Spills in Relationship to Sea Ice Motion
Sea ice on a scale of a few kilometers must be treated as a granular material rather than a continuum. The floes are in nearly constant motion relative to a fixed frame and each other....

Hazardous Waste: Closing the Insurance Gap
Insurers are withdrawing from the hazardous waste field because of large claims and increased risks. Therefore, cleanup contractors are being forced to look for alternative ways to protect...

Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...

Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...

Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...

A Riverine Toxic Spill Model
In the event of a spill of toxic material reaching the main stem of the Potomac River, predictive information regarding its location and concentration would aid in the minimization of...

Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...

Indoor Air Quality Simulations with the Mass Balance Model
Recent studies relate energy conservation measures, specifically to reduction of the air exchange rate of residences, with potential adverse health effects due to human exposure to increased...

Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
