Abstract
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 × 10-7 cm/s), and to determine the breakthrough and transit times of water and tracers through the liner. The liner, 8 × 15 × 0.9 m, was constructed in 15-cm compacted lifts using a 20,037-kg pad-foot compactor and standard engineering practices. Estimated saturated hydraulic conductivities were 2.4 × 10-9 cm/s, based on data from large-ring infiltrometers; 4.0 × 10-8 cm/s from small-ring infiltrometers; and 5.0 × 10-8 cm/s from a water-balance analysis. These estimates were derived from 1 year of monitoring water infiltration into the linear. Breakthrough of tracers at the base of the liner was estimated to be between 2 and 13 years, depending on the method of calculation and the assumptions used in the calculation.
