Column and flow cell experiments to study influence of wetting and mass transfer properties of organic chemical mixtures in vadose zone materials.


EMSL Project ID
20497

Abstract

The project “Influence of wetting and mass transfer properties of organic chemical mixtures in vadose zone materials on groundwater contamination by nonaqeous pahse liquids” has recently been funded by the DOE, Office of Science, within the EMSP program. The project is a collaborative effort between the University of Illinois and PNNL. A considerable part of the experimental effort is planned to be conducted at the Subsurface Flow and Transport Experimental Laboratory (SFTEL) in the EMSL. We request access to the EMSL flow laboratory to complete Task 2 as outlined in the attached pdf. The specific objectives of this work are to determine the effect of organic chemical mixtures on surface wettability, determine the effect of organic chemical mixtures on CCl4 volatilization rates from NAPL, and accurately determine the migration, entrapment, and volatilization of organic chemical mixtures.
