Lush <br /> Date Received: 3-17-87 Laboratory# 8703SO97 <br /> Date Analyzed: 3-20-87 <br /> f1 Procedure: <br /> The soil samples referenced on the attached Chain-of-Custody were <br /> A 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 /> �-_ detector (FID) . The limit of detection for these samples is 0.05 <br /> milligrams/kilogram (parts per million = ppm) . <br /> The results are presented in the table below: <br /> r.
