ABSTRACT: Since 1999, hydraulic conductivity values in till have been measured by the laboratory standard test method ASTM D 5084 on undisturbed soil samples taken at depths between 3.0 m to 6.0 m (10 to 20 ft) in glacial till soils in western Ohio. Their rates on uncracked soil vary from [10.sup.-6] cm/sec to [10.sup.-9] cm/sec. Measurements made on till with cracks vary from [10.sup.-5] cm/sec to [10.sup.-8] cm/sec. Suggestions are made for future studies.

INTRODUCTION
In recent years the existence of cracks in glacial till and their affect on soil hydraulic conductivity has aroused interest. A meeting was ...
