With the promulgation of the Resource Conservation and Recovery (RCRA) Subtitle D, landfills situated within seismic impact zones must be evaluated for seismic hazards to demonstrate that the containment structures of the landfill can resist the maximum horizontal acceleration in lithified earth materials (bedrock) for the site. If a landfill is sited on saturated soils, it must also be evaluated for liquefaction and lateral spreading. In 1994, EMCON evaluated the seismic hazard for a landfill located along the Columbia River in southwestern Washington. The landfill was founded on dredge fill over natural alluvial deposits. Laboratory testing and state-of-the-art engineering analyses indicated that the sand unit below the landfill had a high potential for liquefaction. The seismic hazard evaluation for the site included a site-specific seismic response analysis, a liquefaction potential analysis, and seismic stability and deformation analysis. The seismic response analysis was conducted for nonliquefied, partially liquefied, and fully liquefied foundation soil conditions. Results are described.
