Application of Mixed Iron Oxides in Subsurface Remediation Technologies
… of mixed iron oxide loaded particles for subsurface remediation at field scale.

Phytoremediation Mechanisms of a Creosote-Contaminated Site
… active in the 1950s until 1973. In 1997, a phytoremediation field study was implemented with the planting of 1,026 hybrid poplar trees and 36 cells of vegetated and unvegetated grass and legume treatments. The hybrid poplar tree phytoremediation system was designed to control infiltration and …

Investigating the Functional Response of a Subsurface Biofilm Community to Xenobiotic Stress
Biologically-mediated subsurface remediation by biofilm communities is a poorly understood process that is spatially and temporally dynamic. Two microbial responses, catabolism and the stress response glutathione-gated potassium efflux (GGKE), to benzene, pentachlorophenol (PCP), or Cd exposure …

A risk management model for environmental remediation projects
… the process of risk management for environmental remediation projects involving contaminated soil. The research assumes some remediation technology has been selected or is the most likely to be selected. It also assumes the owner of the site must cleanup the site per existing environmental …

Solubilization of volatile organic compounds in edible nonionic surfactants
Volatile Organic Compounds (VOCs) are major subsurface contaminants and exist as Non-Aqueous Phase Liquids (NAPLs) in the subsurface. Pump-and-treat remediation is the most common technology used to remediate contaminated groundwater. However, experience has revealed that the traditional …

Modeling of Foam Flow in Porous Media for Subsurface Environmental Remediation
… geological formations and shallow subsurface in-situ NAPL (non-aqueous phase liquid) environmental remediation in contaminated soils and aquifers. In those applications, foams are known to reduce the mobility of gas phase by increasing effective gas viscosity and improve sweep …
