H21P:
Innovations in Subsurface Contaminant Transport and Remediation I

Submit an Abstract to this Session



Session ID#: 34604

Session Description:
Our understanding of contaminant behavior in subsurface environments is increasing rapidly. This session presents a forum to share recent advances in our understanding of the physicochemical processes affecting the fate, transport, and remediation of subsurface contaminants. We welcome theoretical, laboratory, field, and modeling research into the coupled, non-linear processes affecting contaminant transport and remediation. These processes span the hydrogeologic, geochemical, radiological, and microbiological domains and include contaminants and/or remediants ranging from organics, metals, radionuclides, and pathogens to nanoparticles and other emerging contaminants. New applications and approaches used to quantify and enhance remediation performance or develop closure strategies are appropriate. Particularly, contributions addressing the sustainability of site assessment and remedial technologies in light of new discoveries are appropriate. Presentations leveraging the synergy of multiple approaches are especially welcome. Broad participation bridging traditional research areas, including groundwater, vadose-zone, groundwater-surface water interface, biology, chemistry, soil- physics, and remediation engineering is encouraged.
