CA 94539 14151 651-1906 <br /> f� <br /> RECORD OF ANALYSIS <br /> Date 6-19-87 <br /> Applied GeoSystems <br /> 43255 Mission Blvd. <br /> Fremont, CA. 94539 <br /> Attention: Charles L. Ard <br /> Date Received: 6-17-87 - Laboratory# 8706WO83 <br /> Date Analyzed: 6-18-87 <br /> Procedure: <br /> The water samples referenced on the attached Chain-of-Custody <br /> were 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 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) tand a Flame Ionization <br /> detector ( FID) . The limit of detection for these samples is <br /> 0 . 0005 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 /> TRAVEL 87048-1 ND ND NDr ND ND <br /> W-70-MW1 87048-1 0 . 0033 ND 0 . 0053 0 . 0038 0. 0550 <br /> W-70-MW2 87048-1 0 . 147 0 . 061 " 0 . 113 0 . 328 2 . 749 <br /> W-70-MW3 87048-1 0 . 0432 0 . 0031 - 0 . 0092 0 . 0128 0 . 5959 <br /> W-70-MW4 87048-1 0 . 0020 0 . 0012 0 . 0052 0 . 0041 0 . 0711 <br /> Results in milligrams/liter ( parts per million = ppm) . <br /> ND=Non Detectable - Less than 0 . 0005 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 (No. 153 ) . <br />
