Using Multiple Water Quality Models for Determining Variable Emission Levels for Wasteload Allocation
We present a methodology for determining the least-cost wasteload allocations from multiple point sources discharging into a single water body. The system of point sources is modeled as...
Substrate Effects on Methanotrophic Trichloroethylene Degradation
Formate up to 1g/L had no significant enhancing effect on the degradation of trichloroethylene (TCE) by three mixed enrichments of methane-oxidizing bacteria. Methanol did not enhance...
Degradation of 1-Naphthylamine by Activated Sludge Using Bioaugmentation
This paper presents the results of ongoing research using a novel bioaugmentation scheme for activated sludge (AS) treatment of trace levels of a hazardous compound (1-Naphthylamine, 1NA)....
Removal of Priority Pollutants in Industrial and Hazardous Wastewaters
With the implementation of effluent standards based on water quality criteria, more and more situations arise where the capabilities of treatment technology is stretched to their limits...
Redevelopment of Remediated Superfund Sites: Problems with Current Approaches in Providing Long-Term Public Health Protection
The normal primary objective of Superfund site remediation is the control of hazardous chemicals so that they do not represent a significant threat to public health and the environment...
Development of Effective Remediation Criteria
Clean-up criteria for remediation of hazardous waste sites take several forms. These vary from simple sensory parameters, e.g., visual evidence of contamination to specific numerical criteria...
Performance Analysis of Remedial Alternatives
This paper demonstrates how remedial action alternatives for a Superfund site can be evaluated using a health-risk basis. The case history for this demonstration is a Feasibility Study...
Construction Management at Sikes Superfund Site
Lockwood, Andrews & Newnam, Inc. (LAN) is providing Construction Management services on the Sikes Superfund site. The project involves constructing an incinerator on-site and incinerating...
The Observational Approach in Environmental Restoration
The U.S. Department of Energy (DOE) has committed to completing environmental restoration of its facilities within the next 28 years (DOE 1990). To achieve this, DOE must ensure that its...
The Ozone Layer: A Critical Analysis of the Management of Public Policy for Fluorocarbons
As environmental public policy becomes increasingly extensive it continues to have greater impact on the lives of each American. The management of the public policy formation process varies...
An Analysis of Modeling Techniques in Pollution Management of Natural Water Systems
This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study...
Who is Taking Out the Garbage?
Due to the shortage of landfill space and the increasing amount of waste being generated, current waste disposal techniques should be studied and revised. New methods should be implemented...
Numerous releases of hazardous substances have occurred at uncontrolled sites all around the United States. These sites pose toxic threats to public health and our environment, and potential...
Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...
Environmental Auditing as a Compliance Tool
This paper will look at how a compliance audit can be used as an effective compliance tool and discuss the key elements of a successful environmental audit program. An environmental audit...
Noise Control Program for the Boston Harbor Project
A noise control engineering program has been instituted for the Boston Harbor project to make the facility virtually inaudible at the property line. The program integrates the noise mitigation...
Information Entropy and Environmental Engineering
Environmental engineering decisions are often made with limited information. In such cases it is useful to express uncertain quantities with a probability distribution. The use of information...
A New Graphic Technique for Reporting Soil Quality Analyses
Boston's Artery/Harbor Tunnel Project is currently the United States' largest highway construction project. One of its major issues is the disposal of an estimated...
Environmental Protection, Resource Allocation and CERCLA: A Practitioners Perspective
In accepting Superfund's mandate of protection of human health and the environment in a timely manner, critics often overlook, the limited human, technical and material resources...
The Effects of Hazardous Organic Pollutants on the Performance of Activated Sludge Systems
The effects of phthalate esters (diethyl phthalate and dimethyl phthalate) and phenols (2,4-dinitrophenol, 2,4-dimethylphenol and 4-nitrophenol) on the performance of a laboratory-scale...
