Phytoremediation project taking up TCE

Article Abstract:

The Environmental Protection Agency's Superfund Innovative Technology Evaluation program at the Naval Air Station Joint Reserve Base Forth Worth was successful in cleaning up contaminated groundwater. The phytoremediation field project used cottonwood trees to see if cuttings, called whips, could absorb trichloroethylene (TCE) as effectively as cottonwood saplings planted in five-gallon buckets. The experiment showed the whips did absorb some amounts of TCE and may cut the cost of cleaning up contaminated groundwater.

Complete dissolution of trichloroethylene in saturated porous media

Article Abstract:

An assessment of the dissolution rates of trichloroethylene (TCE) in glass bead, mixed sand and treated soil porous media reveals that there were trace TCE remaining in the soil and that the remaining TCE was sorbed into the porous medium. Porous media containing the compound at residual saturation were flushed with water and controls that include column design and experimental methods aimed at reducing the effect of column materials on effluent concentrations.

Wettability changes in trichloroethylene-contaminated sandstone

Article Abstract:

Initially wet quartz slides' exposure to industrially-used trichlorethylene, which would contain solutes and breakdown products related to its previous use, can cause a contact angle change. The modification of the wetting properties in sandstone cores is discussed.
