Abstract: Soil vapor extraction column experiments were performed to investigate contaminant removal and its interaction with soil air permeability. Water, TCE, and PCE, and a mixture of TCE and PCE were used as contaminants. Three ...

Abstract: Previous studies have shown that the dry deposition of semivolatile organic compounds to the Great Lakes can account for a significant fraction of their total inputs. However, there is no generally accepted method to ...

Abstract: A new theoretical model to analyze the measurements obtained from a typical soil column venting experiment is proposed. The principles of mass transfer, Darcy's law, and air compressibility in the form of pressure-volume ...

Abstract: In this project the use of natural media filtration (NMF) was evaluated for its ability to remove colloidal particles from the aqueous phase as a function of ionic strength and filter media type by determining first-order ...

Abstract: The purpose of this research was to study the effect of surfactant structure and micelle composition on the partitioning of sparingly soluble organic compounds (SSOCs) into surfactant micelles. The surfactants used in this ...

Abstract: In this project, the ability of natural media filtration (NMF) to remove colloidal particles and associated hydrophobic organic compounds from the aqueous phase was evaluated by performing sorption and transport experiments ...

Abstract: Per- and polyfluoroalkyl substances (PFAS) can occur in groundwater at elevated concentrations due to use in numerous commercial and industrial applications. Foam fractionation, which utilizes the surfactant properties of ...
