Remediation System Optimization with Alternatives
This work applies the enhanced multi-objective robust genetic algorithm (EMRGA) (Beckford and Chan Hilton, 2004) to Fort Ord's Site OU2 for optimal groundwater remediation under uncertainty....
Modeling Fort Ord Site OU2's Remediation System Using Optimization
Fort Ord.s Site OU2 is located approximately 80 miles south of San Francisco near Monterey Bay in Monterey County, California. Fort Ord contains two landfills which were used for residential...
Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...
National Water Quality Assessment: Moving from Measurement to Understanding
The USGS National Water Quality Assessment (NAWQA) program began in 1991. The objectives of the program were to characterize the quality of the Nations ground and surface water, assess...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
VOC Inventory at New York City Wastewater Treatment Plants
Although the New York State Clean Air Act Amendments of 1990 (CAAA) implementation plan is not yet in place, the Citys Department of Environmental Protection (DEP) is taking a proactive...
Study of Biological Reactors for Control of Odor, VOC and Toxic Emissions from Wastewater Treatment Plants
An experiment was performed to assess the use of biological reactors to treat off-gases from publicly owned treatment works (POTWs) containing low concentrations of hydrogen sulfide (H2S)...
Optimization of Soil Vapor Extraction System Design
Soil vapor extraction is a cost-effective technique for the removal of volatile organic compounds (VOCs) immobilized in the unsaturated zone. The design of a soil vapor extraction system...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
The Performance of Unconfined Hollow Fiber Membranes as Pipe Flow and Mixed Flow Aerators
Unconfined gas permeable membranes situated within mixed reactors are currently being evaluated as a viable technology for gas transfer. The use of sealed hollow fiber membranes that are...
Control of Odor and VOC Emissions at Wastewater Treatment Plants -Boston Harbor Case Study-
Siting of the new wastewater treatment plant (WWTP) for the Massachusetts Water Resources Authority (MWRA) in Boston was based on an assumption of mitigation of total reduced sulfur (TRS)...
Emissions, Ambient Concentrations, and Potential Health Hazards of VOCs from Wastewater Treatment
Volatile organic compounds (VOCs) are yielded from wastewater treatment. The potential environmental and health hazards imposed by VOCs has only been recently determined. VOC emissions...
Transportation Planning and Air Quality II
This proceedings,
MSA for VOC Removal
In what may be the first large-scale application of its type, mechanical surface aeration�usually used in wastewater treatment�is removing volatile organic compounds from potable ground...
In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...
VOCs: The New Effluent
The Clean Air Act of 1990, in addition to many state and local regulations, has officials of publicly-owned treatment works (POTWs) shifting their focus, and funds, to air toxic emissions...
Designing for Corrosion Control
This presentation will discuss designing from several aspects: a. Designing of the item to lessen the affects of corrosion. b. Selection of non-corrosive materials in the designing process...
Transport of Volatile Organic Compounds (VOCs) Through a Clay Liner
A series of tests have been performed using laboratory-scale flexible wall permeameters. A synthetic organic leachate mixture of methylene chloride, toluene, and trichloroethylene (TCE)...
Destruction of VOC's By Thermal Oxidation
The Clean Air Act Amendments of 1990 call for the regulation of 189 air toxics and requires control standard benchmarks of Maximum Achievable Control Technology (MACT). These emissions...
Design Considerations for Control of Volatile Organic Compounds at Wastewater Treatment Facilities
New federal and state regulations require publicly owned treatment works (POTW's) to consider emissions of volatile organic compounds (VOC's) as potentially significant...
