Fate and Transport of Metals in a River System
A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a...
Field Scale Solidification/Stabilization of Hazardous Wastes
The selection of appropriate remedial action measures only takes place after a full evaluation of all feasible alternatives. An alternative to off site disposal is solidification/stabilization...
Quantifying the Exposure
Methods of categorizing and modeling of exposure will be presented. The use of modeling for the estimation of population exposure will also be examined and some errors inherent with such...
Arsenic Contamination of Private Potable Wells
The results of a series of water testing programs of private residential wells in Pepperell, Massachusetts showed that of 301 wells tested, approximately 12 percent exhibited arsenic levels...
Risks from Metals Emitted by Sludge Incinerators
The types of incinerators most commonly used in the United States are the multiple hearth and fluidized bed designs. Airborne contaminants from either method of sludge incineration may...
Evaluation of Risks Associated with Dioxin Emissions From a Resource Recovery Facility
Dioxin emissions from resource recovery facilities are a current concern to the application of this technology in the disposal of municipal refuse. A quantitative risk assessment performed...
Hazard Assessment of Landfill Fire Air Emissions
The PJP Landfill, located in northeastern New Jersey, is a suspected hazardous waste site, and is listed on the federal Superfund National Priorities List. In addition to contaminating...
Health Effects Evaluation?Ocean Disposal of Sludge
Court rulings have recently allowed the ocean disposal of municipal wastewater sludge in certain cases. This paper describes a methodology which was developed to determine acceptable loadings...
Uncertainty in Unsaturated Zone Pollutant Transport
The portion of a pollutant spill transported to an underlying aquifer is uncertain due to the stochastic nature of precipitation and uncertainty in the geochemical properties of the contaminant...
Health Hazard Assessment of Waterless Remote Site Waste Management Technologies
The United States Army Construction Engineering Research Laboratory (USA-CERL) has had an ongoing research program addressing remote site waste treatment technologies. The potential for...
RCRA Compliance During Remediation of Waste Sites
The author discusses the impact of the proposed National Contingency Plan revisions of February 1985, which require that remedies under Superfund must attain or exceed applicable or relevant...
Adsorption and Release of Heavy Metals in Contaminated Soil
This study investigated the adsorption and release rates of toxic metals in soil type associated with hazardous waste sites common to the Northeastern United States. Five heavy metals...
Carcinogen Risk Assessment
The various approaches to assessing carcinogen risk are described and evaluated....
Chemicals in the Environment: An Approach to Estimate Magnitude of Risk
This paper provides an overview of application of toxicological procedures to estimate health risks posed by hazardous materials in the environment. Emphasis will be placed on information...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Statewide Port Assessment?Louisiana Case
The Louisiana Statewide Ports Assessment (LSPA) has been conducted of significant changes in the economic environment of the State, Nation and world, which influences not only trade patterns...
Coastal Management Problems in the United Kingdom
Five case-studies from the East coast of England illustrate some of the obstacles facing more enlightened coastal management in the United Kingdom. All the examples demonstrate unsatisfactory...
The Conservancy Concept
During the last nine years in California, the only significant new initiatives in regional land use management have been the creation of Conservancies. With the creation of the Coastal...
