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...

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...

Reversal of Historic Water Level Decline Has Surprising Consequences
(No paper) This paper discusses the causes of the water level rise and options available to the building owner to deal with both the rising water table and VOC contamination....

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)...

Vapor Phase Biofiltration for Removal of VOCs
The selection of an appropriate packing material for the biofiltration process is an important factor in the removal of contaminants from vapor phase. This study evaluates two different...

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...

PCE in Dewatering Flows—A Case Study Risk-Based Clean-Up Action Levels
Up to 70 micrograms per liter (μg/L) of tetrachloroethylene (PCE) was detected in dewatering flows associated with a construction project (Project) in the City of Los Angeles. Because...

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...
