Emerging Environmental Clean-Up Responsibility
This paper is a summary of the structure of regulations requiring clean-up of sites when closed or sold, specifically the State of New Jersey's Environmental Cleanup Responsibility...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
Age-Specific Cancer Risk Analysis for a Population Exposed to Contaminated Drinking Water
Recent developments in the methodology for estimating cancer risk for environmental contaminants exhibit promise for improved predictability of risk analyses based on EPA risk guidelines....
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,...
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...
Land Treatment of API Separator Sludge
An extensive research project was undertaken to establish design and operational guidelines for treatment of oily sludge using land treatment systems. Forty-five test plots were established...
Land Treatment of Refinery Wastes
The authors discuss: waste characteristics; land treatment; and cost comparison with incineration....
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...
Lime Sludge Lagoon Dewatering Using a Mobile Belt Filter Press
A major company was faced with the removal of 2100 cubic yards of lime sludge stored in three lagoons. Because the sludge contained relatively high concentrations of tin and nickel, it...
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...
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....
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...
