Improving Our Understanding of the Impact of Contaminants Stored in Low Permeability Zones
Tuesday, November 29, 1:45–4:30 pm
International Ballroom West (Concourse Level)

Chair:  Dr. Charles Newell, GSI Environmental Inc.

Keynote:  Dr. Thomas Sale, Colorado State University – Department of Civil & Environmental Engineering

Description:  Contaminant storage in low permeability zones (LPZs) occurs through diffusion or sorption of dissolved-phase contaminants over time. It is increasingly clear that understanding the potential for contaminant storage and subsequent release from LPZs is critical to effective site management. LPZs may serve as long-term sources of contaminants, thus limiting our ability to reach groundwater cleanup goals. Alternatively, processes within or near LPZs may control any back diffusion of contaminants. This session focused on current efforts to improve the characterization and treatment of contaminants in LPZs.
