Water and Tritium Movement through the Unsaturated Zone at a Low-Level Radioactive-Waste Disposal Site Near Sheffield, Illinois, 1981-85

摘要

The report characterizes water and tritium movement through the unsaturated zone in an area within the Sheffield disposal site. The report describes (1) the physical setting of the study area; (2) the physical and hydraulic properties of unconsolidated geologic materials; (3) the timing, paths, quantity, and rate of water movement through the unsaturated zone; (4) the factors that influence unsaturated-zone water movement; (5) the spatial and temporal patterns of tritium concentrations within the unsaturated zone; and (6) the application of study-area results to the site as a whole.
