17o Water Content {%) - based on dry weight of the sample and 

 measured to the nearest whole percent. 



18. Maximim Porosity {%) - the percentage of pore space in the total 

 vol\jme of the uncorapacted sample not occupied by solid matter; 

 computed by the formtila, P = 100 (V - ^), where P is the porosity 

 in percent, V is the bulb volimie, and v is the aggregate volume 

 of the grains. 



19. Minimum Porosity {%) - the percentage of pore space in the total 

 volume of the compacted sample not occupied by solid matter; 

 computed by the same formula as given in maximum porosity. 



20. Odor - a qualitative description of any noticeable odors. 



21. Rigidense (mm.) - determined by means of a Rigidense instrument 

 and measirred to the nearest millimeter. For a detailed description 

 of this test procedure refer to: Jaffe, G. and Gaetano, F. W., 



"A Comparison of Atterberg and Rigidense Tests for the Measure of 

 Plasticity", U. S. Navy Hydrographic Office Technical Report No. 11, 

 May 1955." 



22. Dominant Mneral {%) - based on microscopic examination of the 

 sand size and larger material recorded in percent. 



23. Other Material {%) - based on microscopic analysis, 



24. Remarks - supplementary information.
