❑l-J GROUNDWATER TECHNOLOGY LABORATORY <br /> ANALYTICAL& CONSUL 77NG,SERW ES <br /> Division of Oil Recovery Systems,Inc. <br /> 4 Mill St., Greenville,NH 03048 <br /> Laboratory Test Results Tel,(603)878-2500 <br /> 6/19/86 <br /> Report No. 20-2894-1 <br /> Submitted to: Robert Juncal <br /> Groundwater Technology <br /> 4080 Pike Lane <br /> Concord, CA. 94520 <br /> Sample Identification: <br /> The attached report covers water samples #27009-27010 taker. by R. <br /> Hughes using 40 ml septum-capped glass vials At site #20-2894, <br /> Stockton, California. <br /> Method: <br /> Analysis was performed for purgeable aromatic priority pollutants <br /> - and xylenes by purge e <br /> and trap gas chromatography with <br /> photoionization and flame ionization detection as per EPA Method <br /> 602. Quantificetion was performed on a very polar column which <br /> fractionates ali hatics <br /> p (up to C12) swap from volatile aromatics. <br /> Chromatographic conditions are referenced in GTL Method Code 110. <br /> Hexane and ortho-xylene are used as calibration standards for the <br /> aliphatic hydrocarbons and miscellaneous aromatics, respectively, <br /> if reported. <br /> Minimum Detection Limit (MDL) at 5 times background is 0.5 ppb <br /> for all parameters. The level for reliable quantitation for the <br /> - summed groups such as aliphatics is 20 ppb. Samples diluted in <br /> order to maintain the calibrated range are so indicated by a <br /> footnote giving the factor by which the MDL is raised. <br /> Sampling and sample handling and preservation are specified by <br /> this laboratory to be as per EPA Method 602. Any irregularities <br /> are referenced in the attached quality assurance report. <br /> Results: <br /> Results are reported in ppb (ug/1). <br /> — Prepared by: <br /> Eileen Foley E.S.L. <br /> Analytical Program Manager Analyst <br /> i <br />
