Preface This report was originally published in May 1993 as a thesis for the degree of Master of Science with a major in hydrology through the University of Idaho. Research for the report was conducted between June 1989 and May 1990. The report contains valuable Wrmation on the hydrogeology along the southern boundary of the Hanfbrd Site; therefbre, the GroundWater Surveillance Project agreed to publish it as a Pacific Northwest Laboratory technical report. Because the report was published in 1993, references are made to activities, organizations, and/or previous investigations that were pertinent at the time, but may no longer be applicable, or have since been updated. Hence, the report remains essentially as it was originally written.
