Lush <br /> Date Received: 9-28-87 Laboratory# 87108038 <br /> Date Analyzed: 10-06-87 <br /> Procedure: <br /> The soil samples referenced on 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 /> 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 /> ETHYL TOTAL <br /> SAMPLE SITE BENZENE BENZENE TOLUENE XYLENES TVH <br /> S-40-B6 86091-6 0.47 ND 0.08 ND 0.85 <br /> S-40-B7 86091-6 ND ND ND ND 0.45 <br /> S-40-B8 86091-6 0. 15 ND 0. 11 0. 12 1.37 <br /> S-40-B9 86091-6 0. 30 ND 0. 06 0.13 1.76 <br /> Results in milligrams/kilogram (parts per million = ppm) . <br /> ND=Non Detectable - Less than 0.05 milligrams/;cilogram (ppm) . <br /> Tia Tran, Chemist Y <br /> Applied GeoSystems is a State of California, Department of Health <br /> Services Certified Hazardous Waste Testing Laboratory (N(,. 153) . <br />
