Ard <br /> Date Received: 6-22-87 Laboratory# 8706S102 <br /> Date Analyzed: 6-25-87 <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 /> 5-20-B1 87048-1 ND ND ND ND ND <br /> 5-25-B1 87048-1 ND ND ND ND 0.63 <br /> �- 5-60-B1 87048-1 ND ND ND ND 0.73 <br /> S-40-B2 87048-1 0. 26 0 . 14 0 . 09 0. 85 2. 47 <br /> 5-50-B2 87048-1 ND ND ND ND 0.83 <br /> 5-60-B2 87048-1 ND ND ND ND 0.74 <br /> 5-30-B3 87048-1 ND ND ND ND 0 . 64 <br /> 5-35-B3 87048-1 ND ND ND ND 0 . 81 <br /> 5-60-B3 87048-1 ND ND ND ND 0 . 48 <br /> 5-60-B4 87048-1 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 />
