<br />*This soil sample was composed of three subsamples A-topsoilwery <br />high in organic materials, B-a sample composed of sand/gravel (39Z less <br />than 2 mm, 13.68 between 2 mm 6 ;" and 47.4X greater than $") and C- a clay <br />based soil. A composite of this soil would not have been valid for the <br />permeability test of the Dam site soil. This soil has been stored for <br />future use if requested. <br />Based on the criteria described the four soils tested for permea- <br />bility were considered to be non-permeable when compacted to 1008 (or <br />greater) of maximum proctor density. <br />1 <br />Dr. Joe Bowden, Ph.D. <br />Director <br />JB/ad <br />• Additional testing as requested by your engineer. <br />A direct shear test on a typical clay sample (CDS 41502 marked as <br />"Borrow Pit") was performed. <br />Standard Conditions: 107.1 PCF <br />l7i moisture <br />95z of max. density <br />Direct Shear: angle of internal friction of 31 degrees <br />Cohesion of 2.4 ksf <br />i <br />
