Short <br /> r <br /> Date Received: 12-4-86 Laboratory# 8612SO12 <br /> Date Analyzed: 12-5-86 <br /> Procedure: <br /> The soil samples referenced an the -attached Chain-of-Custody were <br /> analyzed for the presence and concentration of Benzene,. <br /> Ethyl-Benzene, Toluene, and Xylenes (BETX) and for :Total Volatile <br /> Hydrocarbons (TVH) by.EPA method 8020. The samples were <br /> ' - concentrated on a Tekmar. LSC-2 and ALS automatic sampler prior to <br /> injection into a 5890 Hewlett Packard gas chromatograph fitted <br /> with a Photo-Ionization detector (PID) and a Flame Ionization <br /> i detector (FIA) . The limit of detection for these samples is 0.1 <br /> milligrams/kilogram (parts per million = ppm). <br /> P <br /> The results.', re presented in the table below: <br /> ETHYL TOTAL <br /> SAMPLE 1.1ENZENE BENZENE ZOLUENE XYLENES TVH <br /> S-15-B1 861_02-1 ND ND ND.
