sites within one week's sampling time. The other was that we hoped to collect samples at sites that reflect relatively high, intermediate and low level NTS fallout. The sites at Alamo, Caliente, Ely, Eureka, and Austin probably reflect sites with a relatively high level of NTS debris. Wendover, Wells, and Elko, At there are probably sites with an intermediate level, and here at Boise, Twin Falls, Malad City, Idaho Falls, and possibly Fredonia, Arizona, might reflect sites with relatively little NTS fallout. That's all for the viewgraphs. As the analytical work proceeds on the actual Phase II samples, EML 10 will supply ORI with reference material, reference soil samples and blanks ll for the blind insertion of samples to the analytical contractor. 12 The reference sample is a 20-kilogram composite of a sample retrieved 13 in northeastern United States which has been processed and analyzed at EML. 14 Approximately 200-gram samples of this composite, a large sample, will be 15 supplied. 16 distinguishable from the appearance of the normal Phase II samples.
