A six-inch by two-inch brass tube was driven <br /> Into the soil with a wooden mallet at three separate sample points within the drum <br /> until full. Each sample tube was capped at each end with plastic caps, taped with duct <br /> tape, and inserted into plastic Zip-loc bags. for analysis for TPHg/BTEX/MTBE. The <br /> water sample was collected from drum # D-W-2 by lowering a 2-inch steel bailer to <br /> the bottoms of the drum and then placing the extracted water into 40 ml VOAs with a <br /> preservative. All samples were placed on ice at 4 degrees centigrade, for transport to <br /> a state certified laboratory. <br /> TPHg concentrations were 90 ppm, ND, 33 ppm, NSD, and 5.9 ppm for drums #D-9, D- <br /> 3, D-4, D-5, and D-6 respectively. Analysis of the water samples identified 250 ppb <br /> TPHg. The contents of the six drums will be trans oded to their a e le ro riatal <br /> • ts of I depgndina upono I •cat' f i w to immediately. <br /> Also, we would like the site considered for closure according to the rationale <br /> presented in the subsurface investigation. <br /> ` D <br /> Sinc rely, �,L1N J 0 a <br /> CERTIFIED <br /> Franklin J.
