A prototype soil liner and a field-scale soil liner were constructed to test whether compacted soil barrier systems could be built to meet the standard set by the U.S. Environmental Protection Agency (EPA) for saturated hydraulic conductivity (< or = 10 to the 7th power cm/s). In situ ponded infiltration rates into the prototype liner were measured with the use of two large (5 m diameter), sealed double-ring infiltrometers. The saturated hydraulic conductivity of the liner was estimated from the infiltration data to be no more than 3.6 x 10 to the minus 8th power cm/s. Measurements of soil tension using pressure transducer tensionmeters indicated that the wetting front had reached a depth greater than 20 cm.
