Proceedings of a specialty conference on geoenvironmental engineering, held in New Orleans, Louisiana, February 24-26, 1995.

This Geotechnical Special Publication (GSP 46) contains 118 papers outlining the current trends, developments, and needs in geoenvironmental engineering. The impact of rapid industrialization around the globe and unsafe waste management practices have become increasingly significant within the last two decades as the disclosed number of unengineered facilities and contaminated sites steadily grows and the anticipated remediation costs increase. A new service sector is emerging in waste containment, soil remediation and environmental restoration. The tasks needed to accomplish the tasks in environmental restoration and waste management place a new responsibility on the services of the civil engineer. It requires collaboration between geotechnical and environmental engineers and prompts the need to cooperate with the chemical, mechanical, and electrical engineers, chemical environmental scientists, microbiologists, groundwater hydrologists and geologists, resulting in the evolution of a geoenvironmental engineering subdiscipline. In line with the different tasks undertaken by the civil engineer serving this sector, papers are organized around four themes: characterization/speciation, fate and transport, containment, and remediation.

Topics include:

• techniques to sample and speciate contaminated groundwater and soil,
• transport of chemical species in soils,
• design/analysis and performance assessment of landfills,
• containment barriers,
• material-waste interactions in landfills,
• settlement, stability and seismic analysis of landfills,
• geosysthetics for geoenvironmental applications,
• hydraulic recovery/containment techniques,
• soil and groundwater bioremediation, and
• solidification and stabilization.

Case histories and reviews of the state of the practice and art are also presented.
