Evaluation of a rapid headspace analysis method for analysis of volatile constituents in soils and sediments

Description: Contamination of the subsurface by volatile organic solvents is a common and significant environmental problem. A critical component of developing an accurate assessment of a site contaminated by these solvents is the acquisition of closely spaced, high quality contaminant concentration data. Many volatile organics are relatively mobile in the subsurface, requiring characterization of both horizontal and vertical contaminant migration. The volatile nature of these analyses, combined with the co… more

Biosurfactants and increased bioavailability of sorbed organic contaminants: Measurements using a biosensor

Description: Bioremediation of sites contaminated with hydrophobic materials that sorb onto the soil matrix is very difficult due to reduced microbial (bio)availability. Following biosurfactant addition, we have measured an increase in contaminant bioavailability by using a lux biosensor. Direct microbial bioavailability was determined by using a genetically engineered microbial bioreporter strain of Pseudomonas putida. This strain was engineered so the lux genes, which code for light production, are transc… more

Geochemistry of FBC waste-coal slurry solid mixtures. Final technical report, September 1, 1992--August 31, 1993

Description: The three tasks conducted in this research project were related to understanding the geochemistry and mineralogy of the co-disposal of fluidized bed combustion (FBC) wastes with coal slurry solid (CSS) from a coal preparation plant. During coal cleaning, pyrite, other heavy minerals and rock fragments are separated from the coal and discharged in an aqueous slurry to an impoundment. After dewatering and closure of the impoundment, the pyrite can oxidize and produce acid that can migrate into th… more

In-situ bioremediation via horizontal wells

Description: This project is designed to demonstrate in situ bioremediation of groundwater and sediment contaminated with chlorinated solvents. Indigenous microorganisms were stimulated to degrade TCE, PCE and their daughter products in situ by addition of nutrients to the contaminated zone. In situ biodegradation is a highly attractive technology for remediation because contaminants are destroyed, not simply moved to another location or immobilized, thus decreasing costs, risks, and time, while increasing … more
