Water contents of samples from the Nevada Test Site: total, free (natural state to 105/sup 0/C), and more tightly bonded (105 to 700/sup 0/C)
To help confirm correct functioning of an epithermal neutron sonde, we measured tightly bonded water content of selected Nevada Test Site (NTS) drill holes. Tuff and alluvium samples were dried overnight at 105/sup 0/C. The samples were then heated for 45 min in a split tube furnace at 700/sup 0/C. The water that came off due to this heating was collected and the amount recorded. The error in this procedure is +- 0.59 wt %. Total water can be calculated for samples from analyses of free and tightly bonded water contents. The maximum error in this calculation is equivalent to the error in determining the more tightly bonded water. Average total water content values have been assigned to geologic units. These values, in weight fraction, are alluvium 0.14 +- .05 and tuff 0.19 +- .04. Further division of the tuff gives values of Rainier Mesa 0.15 +- .01, Paintbrush 0.18 +- .03, Tunnel Beds 0.20 +- .04, and Grouse Canyon 0.29 +- .02. Statistically significant differences occur between the tuff and alluvium. Within the tuffs, these differences also occur between Grouse Canyon, Rainier Mesa, and Paintbrush/Tunnel Beds. Paintbrush and Tunnel Beds cannot be distinguished by this method.
