Slurry Bioremediation of Petrochemical Waste Sludges
Slurry bioremediation testing was conducted on waste sludges from petrochemical production. The study concludes that the apparent mechanism for remediation of the waste involves an initial...
Assessment of Effects of a Water Supply Withdrawal on Downstream Flows for Anadromous Fish Reproduction
A BASIC computer model was developed to simulate reservoir operations in conjunction with a proposed water supply withdrawal. The model was used to assess the potential impacts of the...
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)....
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...
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...
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...
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...
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...
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...
Allocating Water Among Urban Users During Droughts
Beginning in the spring of 1987, California has been besieged by a drought that, as of this writing, has not yet abated. In response to this unprecedented drought, the San Francisco Water...
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....
