Geological site characterization for the proposed Mixed Waste Disposal Facility, Los Alamos National Laboratory

摘要

This report presents the results of geological site characterization studies conducted from 1992 to 1994 on Pajarito Mesa for a proposed Los Alamos National Laboratory Mixed Waste Disposal Facility (MWDF). The MWDF is being designed to receive mixed waste (waste containing both hazardous and radioactive components) generated during Environmental Restoration Project cleanup activities at Los Alamos. The chapters of this report focus on surface and near-surface geological studies that provide a basic framework for siting of the MWDF and for conducting future performance assessments, including fulfillment of specific regulatory requirements. This work includes detailed studies of the stratigraphy, mineralogy, and chemistry of the bedrock at Pajarito Mesa, studies of the geological structure and of mesa-top soils and surficial deposits, geologic mapping and studies of fracture characteristics and studies of potential landsliding and rockfall along the mesa-edge.
