Witham <br /> Date Received: 8-25-87 <br /> Date Analyzed: 9-1-87 Laboratory# 8709WQ09 <br /> Procedure: <br /> The water samples referenced on the attached Chain of Benzene, <br /> -of-Custody <br /> irk <br /> were analyzed for the presence and concentration <br /> .�` Ethyl-Benzene, Toluene, and Xylenes (BEI'X <br /> Hydrocarbons (TVH) by EPA method 602. The samples werel volatile <br /> concentrated on a Tekmar LSC-2 and AGS automatic sampler prior to <br /> injection into a 5890 Ilewlett Packard <br /> with a Photo-Ionization detector (pi3J)g`�s cl�ramatograph fitted <br /> detector, (FID). 'iii4 alt1Cl a .Flame Ionization <br /> eft limit of detection for these samples is <br /> 0.0005 MIII;ararrs/liter (parts per million = ppm). <br /> The results are presented in the table below: <br /> ETHYL TOTAL <br /> I•A SAP7PLE SITE BENZENE BENZENE TOLUENE_ xYLENESg <br /> W-51-MW1 87050-2 ND 0.0039 ND <br /> 18 0.0995 <br /> W-51-MW2 87050-2 ND ND 0.. 0.0006 0.1063 <br /> 0021 . <br /> 0.00 <br /> W-51-M43 87050-2 0.0027 ND 0.0021 0.0007 0.1509 <br /> 063 <br /> Results in. milligrams/liter (parts per million <br /> ND=Non Detectable - Less than 0.0005 milli rams/liiter. <br /> g (Ppm). <br /> TI Fran, Chemist <br /> Applied QeaSystems is a State of California, Department of Health <br /> Services.
