damp plastic clay; no evidence of water was noted. Because of ' the extreme plasticity of the clays, 1t was not possible to obtain a soil sample by driving a brass tube into the bottom of the hole. A new, properly cleaned 2" diameter brass tube was filled with soil from the fins of the auger flxght. The sample ' was promptly sealed, labeled, and placed on ice for preservation. Another sample from the auger teeth was placed in a plastic tube, sealed, and warmed in the sun. The probe of the PID meter was ' inserted into the tube and gave a reading of 2ppmv. A sample was also crushed, placed in water and allowed to warm for several minutes. Visual inspection did not reveal any color on the water surface or evidence of free product. Refer to Plot 2A and Plate KI for more details. While Auger "A" was being advanced with the rotary hammer, Mr. ' Ramero began work at Auger "B" , located 50 ' due south of Trench #3; refer to Plate VII for details. Using the 3 1/4" hand auger, the boring was advanced to a depth of 9 '411. The soils consisted ' primarily of sandy clay loam, with sandy clay at the bottom. Moisture was noted at about 8' , and the soils became very wet below 8'8% Because of the moisture, it was not possible to obtain a soil sample from the bottom of the boring. A 14 ' length of slotted 2" FVC was set on bottom to enable obtaining a water sample after the hole had stabilized_ No odors or evidence of contamination were noted. After completion of Auger "A" , the truck mounted power hammer equipment was relocated immediately adjacent to Auger "B". This ' boring was labeled B ' , but is not shown on Plate VII. After thorough steamcleaning of all equipment, a 2" auger-hole was advanced to approximately 7 '6". Two attempts were made to obtain a 5011 sample by driving a soil sample catcher containing a 2" brass tube into the bottom of the hole. However, due to the extreme plasticity of the clays, which swelled when penetrated, the sample was sucked out of the tube when withdrawn. The hand-auger was then thoroughly steam-cleaned and used to enlarge the boring. A clean brass tube was then inserted into the sample holder , (which had been thoroughly cleaned, ) and ' driven into the bottom of the boring. A sample was obtained in this manner at a depth of 7'611; it consisted of sticky, damp, bluish-gray to tan sandy clay. There was no evidence of ' contamination noted. The brass tube was promptly sealed, labeled, and placed on ice for preservation pending transfer to the laboratory. Refer to Plots 2B & 2C for more information. ' After completion of Auger "B ' " , all equipment was again steam cleaned prior to further use. 5 1
