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...
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...
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...
The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
Monte Carlo Simulations of Uncertainties in Risk Assessments of Superfund Sites Using Crystal Ball?
Most health risk assessments for Superfund sites combine a series of worst case assumptions to derive a 'point estimate' of risk that is 'conservative,'...
Gamma Exposure from Rn Progeny in GAC Units
An investigation into the gamma exposure rate generated by granular activated carbon (GAC) water treatment units focused on ten sites that covered a range of source radon (Rn) in water...
Hazardous Waste Disposal: An Attitudinal Affront
Modern disposal facilities are thorough and conscientious in their methods. Environmentally sound practices are essential to protect the company and its clients from liability. The average...
The Application of Risk Assessment at Hazardous Waste Sites
This paper discusses some of the recent innovative uses of risk assessment at hazardous waste sites. Important developments in both methodology and application are as follows: quantitative...
Risk Assessment for the Multiple Threat from Dioxin Analysis
In this paper, the author focuses on the integrated method of estimating the risks and the evaluation of the risk acceptability based on a systematic classification of all risks involved...
A Practical Approach for Evaluating Environmental Risk
Risk management and assessment techniques are increasingly being used to project public health risks at hazardous wastes sites. Few studies have quantitatively evaluated the environmental...
Indoor Radon: Site Evaluation
The soil parameters most important in evaluating the indoor radon potential of a building site are the soil radium concentration, the soil-gas radon concentration and the permeability...
Development of a Sanitary Landfill Design in New Jersey?Why Proposed RCRA Changes are Not Going to Affect the Design
On August 24, 1988, the U.S. Environmental Protection Agency (EPA) proposed substantial revisions to Subtitle D of the Resource Conservation and Recovery Act (RCRA). In most states the...
Ft. Huachuca, AZ Fire Site Hazardous Waste Remedial Action
The paper discusses an investigation of the site of a major fire at Ft. Huachuca, Arizona. All of the fire debris contained asbestos. The sampling results confirmed that PCB levels of...
Closure of Hazardous Surface Impoundments and Creation of an On-site Permanent Disposal Facility?A Case History
Remington Arms Co. is currently undertaking a RCRA closure program for nine surface impoundments in Lonoke, Arkansas. The impoundments contain a variety of listed hazardous wastes from...
Preacquisition Environmental Site Assessments: Avoiding Common Errors and Omissions
The 1986 Superfund Amendments and Reauthorization Act (SARA) established an 'innocent-purchaser' defense to environmental liability from ownership of contaminated...
Computerized Data Processing, Displays and Groundwater Flow Analyses of the Stringfellow Hazardous Waste Site
Several types of data, maps, and figures were obtained from various sources involved in the investigations and monitoring at the site. This information was discretized, and a computerized...
Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...
Radioactive Mixed Waste at the Waste Isolation Pilot Plant
This paper discusses compliance by the U.S. Department of Energy Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico with the Resource Conservation and Recovery Act (RCRA) (1)....
An Evaluation of Hazardous Waste Land Treatment Closure Options
The purpose of this research was to evaluate changes in the persistence and mobility of the residues remaining when hazardous waste land treatment (HWLT) sites are closed. This evaluation...
Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
The unknown or uncertain conditions often inherent in hazardous waste site remediation projects complicate the job of the responsible professional to adequately assess and manage associated...
