Although many high readings are near the air-ground interface, concentrations at depths up to 29.2x102 28.0X10 , 140 cm ara significant. Except for four locations, clustered near the "right-side" of the field, profiles decrease to less-than 40 pCi/g within about the top 35 cm. Samples will be taken to a depth of 40 cm at 10 cm increwents and at 20 m intervals (864 samples). A the hiph-vatue area (140 m X 200 m), samples will be taken to additional depths of 100 cm (680 additional samples). 23 30° 11 15 93 Samples were from widely separated locations, ench with adjacent analyses that did not exceed 40 pCi/g, which suggests that no extended hot spots ; 100 : 4,0x10 The one high reading, from the middle, are present. northern side of the runway, will be investigated. Samples at 10 em increments to depths of 160 cm will be collected from 10 locations in an area approx imately 50 m X 80 m encompassing the high value.
