Lush <br /> Date Received: 8-20-87 Laboratory# 87085119 <br /> Date Analyzed: 8-25-87 <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 /> 50820-1 87053-1 ND ND ND ND ND <br /> S0820-2 87053-1 ND ND ND ND ND <br /> 50820-3 87053-1 ND ND ND ND ND <br /> S0820-4 87053-1 ND ND ND ND ND <br /> Results in milligrams/kilogram (parts per million = ppm) . <br /> ND=Non Detectable - Less than 0 .05 milligrams/kilogram (ppm) . <br /> Tia Tran, Chemist <br /> Applied GeoSystems is a State of California, Department of Health <br /> Services Certified Hazardous Waste Testing Laboratory (No. 153 ) . <br />
