PCB Contamination of a Mass. Harbor: Technical Challenges for a Remedial Solution
The highest priority uncontrolled site in Massachusetts, the New Bedford Harbor Superfund site, is contaminated with high concentrations of PCBs. The magnitude and nature of contamination,...
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...
A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...
Environmental Auditing ? A Management Tool

Innovations in Army Treatment of Remote Site Wastes
The U. S. Army Construction Engineering Research Laboratory (USA-CERL) is currently evaluating new methods for waste treatment at remote sites which will eliminate or mitigate problems...
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...
Impact of Metallic Solders on Water Quality
A description is given of first-draw water testing at residences in a Long Island, N. Y. , water district. Results for heavy metals, particularly lead, leaching from the solder and plumbing...
Enforcement Support at an NPL Landfill in Colorado
Since 1964, the City and County of Denver has owned the Lowry Landfill site, located approximately 15 miles (24 km) southeast of Denver. During the period of July 1967 through 1980, the...
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...
Issues in Dam Grouting
Although perhaps the largest number of individual grouting projects do not involve dams, by far the largest volume of grout used is for grouting of new or existing dams. This volume presents...
Survival of Ocean Life: The Critical Balance
Several major problem areas in ocean management are in need of immediate and stringent address. Excessive erosion and sedimentation, stems from man's inadequacies in land...
Overview of EPRI'S Solid Waste Environmental Studies
The Electric Power Research Institute (EPRI) initiated a comprehensive research project in 1983 with the long-term goal of improving and validating methods for predicting the fate of chemicals...
Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters
The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other...
Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...
Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...
Foam Grout Saves Tunnel
Pittsburgh's 81 year old Mt. Washington tunnel has been made safe for many more decades of light-rail transit use, with the use of foamed chemical grout. The job is the first...
Construction and Performance of Salvajina Dam
Salvajina Dam was constructed between July, 1982 and November, 1984. Relevant construction aspects are described, particularly those related with procedures and statistical data of the...
Slurry Trenches for Containing Hazardous Wastes
Slurry trench technology has not advanced much during the past 10 years due to a lack in research and development, the excerbated litigious climate in the environmental protection field,...
Assessing the Effects of Water Contamination
