Lush <br /> Date Received: 11-24-86 Laboratory# 8611WO89 <br /> Date Analyzed: 11-24-86 <br /> Procedure: <br /> The water sample referenced on the attached Chain-of-Custody was <br /> analyzed for the presence and concentration of Benzene, Ethyl- <br /> Benzene, Toluene, and Xylenes (BETX) and for Total Volatile <br /> Hydrocarbons (TVH) by EPA method 602. The sample was concentrated <br /> on a Tekmar LSC-2 and ALS automatic sampler prior to injection <br /> into a 5890 Hewlett Packard gas chromatograph fitted with a <br /> Photo-Ionization detector (PID) and a Flame Ionization detector <br /> (FID) . The limit of detection for this sample is 0. 001 <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 TVH <br /> W-50-MW4 8691-4 0. 024 0. 003 0. 157 0 . 022 0. 305 <br /> Results in milligrams/liter (parts per million = ppm) . <br /> ND=Non Detectable - Less than 0. 001 milligrams/liter (ppm) . <br /> Tia Tran, Chemist <br /> Applied GoeSystems is a State of California, Department of Health <br /> Services Certified Hazardous Waste Testing Laboratory (No. 153 ) . <br />
