Primary Position Function/Summary:

Participate in research focused on understanding and modeling the subsurface transport of dense non-aqueous phase liquid (DNAPL) contamination, such as chlorobenzene. The position will support a series of one-dimensional benchtop soil column experiments designed to measure DNAPL dissolution rates, dissolved-phase transport parameters, and capillary pressure–saturation relationships. The selected candidate will assist with experimental design, column packing and operation, chemical analysis, data processing, and documentation to support an ongoing MODFLOW 6 contaminant transport modeling effort.

Additional Information:

This academic hourly position is intended to support current research activities and may offer the opportunity to transition into a formal position in the future, depending on project needs, funding availability, and demonstrated performance.

Major Duties and Responsibilities: 

95% - Research

• Pack one-dimensional soil columns with site-representative aquifer materials (sands, silts, and clays) for benchtop flow-through experiments.
   • Establish and operate column flow systems using peristaltic pumps, and monitor flow rates, pressures, and effluent collection.
   • Operate and maintain analytical instrumentation, including SPME-GC-MS, to measure dissolved chlorobenzene concentrations in column effluent.
   • Collect, organize, and analyze experimental data, including dissolution curves and breakthrough curves, and fit transport parameters (effective mass-transfer coefficient, longitudinal dispersivity, and retardation factor) for incorporation into the MODFLOW 6 model.
   • Maintain accurate laboratory records, including experimental conditions, observations, results, and chemical safety documentation.
   • Assist with preparation of reports, presentations, figures, tables, and other project-related documents.
   • Conduct literature searches related to DNAPL dissolution, contaminant transport, multiphase flow, and groundwater modeling.
   • Maintain laboratory supplies and inventory, manage hazardous chemical waste, and keep a clean and safe working environment.
   • Perform other research tasks and analyses as needed to meet project goals and deliverables.

• Draft data summaries, reports, and presentations. 

5% - Other

• Keep abreast of developments in contaminant hydrogeology, DNAPL remediation, and groundwater transport modeling.
 • Perform other duties as assigned to support the mission and goals of PRI/ISTC.
