Objective:

The primary hypothesis is that natural variability of soil characteristics and variability due to nonaqueous-phase liquid (NAPL) entrapment result in preferential flow of water and treating agents. These constraints to flow and delivery of treating agents alter effectiveness of treatment schemes in the field. This research will attempt to identify the basic processes affected by these complexities and determine the parameters that control the behavior at the field scale.

Approach:

A systematic procedure to extend to the field the knowledge gained through experimentation at the laboratory scales of pore, cell, column, and soil flumes will be developed. Laboratory research, modeling, and field investigations will focus on issues related to transport; entrapment; recovery; dissolution; fingering; physical, chemical, and thermal mobilization; blob dispersion to increase dissolution, etc., which are of fundamental importance in developing remediation technologies. Laboratory experiments in cells, columns, and large tanks will be continued to identify basic parameters which need to be upscaled to field problems. Some of the parameters that have been identified for study include hydraulic conductivity, capillary pressure versus saturation, relative permeability, entry pressure, pore-size distribution, dispersivity, sorption coefficient, mass transfer coefficients, and dissolution parameters. Investigators will use chemical mixtures to look at multicomponent mass transfer and realistic field soils. Sites in Kansas, Colorado, Wyoming, and Louisiana will be selected for field studies. Once effective parameters are identified, techniques will be developed to obtain these in the field.

Expected Results:

The expected results of this research are to develop and implement systematic procedures for applying, in the field, treatment and remediation technologies for jet fuel, de-icing compounds, and other NAPLs that have been developed in the laboratories.
