Current research has been focused in the areas of subsurface remediation, waste containment systems, contaminant transport modeling, and usage of waste and recycled materials for engineering applications.

Research on subsurface remediation is aimed at developing simple, safe, economical and efficient in-situ remediation methods to clean up contaminated soils and groundwater. Currently, electrokinetics, chemical oxidation/reduction and air/ozone sparging technologies are being investigated to remediate contaminated soils and groundwater. Integration of these technologies with other common technologies to remediate mixed contaminant sites is also being pursued.

Research on waste containment systems encompasses both the evaluation of the mechanical stability of liner systems as well as modeling contaminant transport through liner systems. Field-scale performance evaluation of bioreactor landfills is also being performed.

Research on recycled materials includes the feasibility investigations on using shredded scrap tires as bedding/backfill material for buried pipes, using scrap and used plastics as soil reinforcing additive, and using shredded scrap tires as protective/drainage material in waste containment facilities.

The following selected projects are described in more detail:

• Electrokinetic Remediation
• In-Situ Air Sparging
• Waste Containment Systems
• Recycled Material Applications
