Lush <br /> Date Received: 10-15-86 Laboratory# 8610-W91 <br /> Date Analyzed: 10-17-86 <br /> Procedure: <br /> The water samples referenced on they attached Chain-of-Custody <br /> were analyzed for the presence and concentration of Benzene, <br /> Ethyl-Benzene, Toluene, and Xylenes (BETX) and for Total <br /> Hydrocarbons (THC) by EPA method 602. 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 0.002 <br /> milligrams/liter (parts per million = ppm) . <br /> The results are presented in the table below: <br /> ETHYL TOTAL <br /> SAMPLE SITE BENZENE BENZENE TOLUENE XYLENES THC <br /> W-50-MW1 8691-3 0. 331 0. 105 0.090 0. 550 3. 750 <br /> W-50-MW2 8691-3 0. 104 0.060 0.020 0. 235 1. 387 <br /> W-50-MW3 8691-3 ND ND ND ND 0.037 <br /> Results in milligrams/liter (parts per million = ppm) . <br /> ND=Non D table - Less than 0.002 milligrams/liter (ppm) . <br /> Tia Tran, Chemist <br /> Applied GeoSystems is a State of California, Department of Health <br /> Services Certified Hazardous Waste Testing Laboratory. <br /> certification No. 153. <br />
