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...
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...
Vacuum Anaerobic Treatment: A New Approach
Anaerobic processes have an organic loading limit that when exceeded leads to process failure. The research summarized in this paper demonstrates that both organic removal rate enhancement...
Optimization of Innovative Biological Treatment
This paper presents the experimental and theoretical development of a method for predicting the optimal operating conditions for an innovative biological reactor design. The innovative...
Trihalomethane Control: A Case Study
Controlling trihalomethanes (THMs) has been an important part of many utilities' water treatment programs since THMs were first regulated in 1979. The increased disinfection...
A Case Study in Sludge Handling
When the Wyoming Valley Sanitary Authority (WVSA) converted its operation to a secondary treatment plant in 1988, something important was missing. That something was a method to handle...
Microbiological Stabilization Through Aerobic Digestion and Storage
A study was conducted to evaluate the pathogen indicator bacterial reductions in the sludges of six wastewater treatment plants. These plants were extended aeration and oxidation ditch...
Chemical Sludge Treatment?A Way of the Future
Recently, chemical treatment of municipal sludges has become an alternative to incineration, composting, and digestion. The commercial processes have evolved into three categories of chemical...
A Water Availability Index for Reservoir Management
This paper extends tha Water Availability Index concept to downstream reservoirs in the Apalachicola-Chattahochee-Flint (ACF) system. This extended index should be helpful in adjusting...
The Mission of the Corps of Engineers, South Pacific Division, in Hazardous/Toxic Waste (HTW)
This paper discusses the various roles and relationships that the South Pacific Division has for HTW activities within the division's four-state area (CA, AZ, NV, and UT)....
California Standards for Characterizing Contamination and Assessing Risk from Hazardous Waste Sites
The Toxic Substances Control Program (TSCP) of the Department of Health Services is responsible for managing California's hazardous waste program. A primary goal of TSCP is...
Ground Water Treatment System Using UV/H2O2 at Sacramento Army Depot
Ground water beneath the Sacramento Army Depot (SAAD) is being extracted and treated as part of a ground water remediation program. The extraction system is achieving contaminant capture...
The State Water Board's New Monitoring Requirements
In coordination with Department of Health Services' (DHS) efforts to gain 'State Authorization' to administer the federal hazardous waste management...
Ground Water Recharge in Central and West Coast Basins
The agencies responsible for the Central and West Coast Basins of Los Angeles County, California have managed their ground water supplies by the artificial recharge of reclaimed and imported...
Plume Management for Groundwater Remediation
Site-specific data for four sites were compiled to evaluate the effectiveness of pumping and treating contaminated groundwater and recharging the treated groundwater to the surficial aquifer....
Effect on Soil and Groundwater Due to Long-Term Land Treatment
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....
