X04 <br /> r'� t <br /> y„ <br /> AGS 87031-2 <br /> USA Station No. li0 <br /> Stockton, California <br /> After ground-water recovery to static conditions, the bailer was <br /> cleaned with Alcono_ and distilled water and the formation water <br /> in MW--1 and MVI-2 was sampled for laboratory analysis. s-1 was <br /> not sampled due to the presence of floating product. The bailer <br /> was lowered through the ground-water surface to a point <br /> approximately 5 to 10 .feet below the water level. The water <br /> sample was then retrieved and slowly transferred to two 40- <br /> milliliter and one 1-liter laboratory-cleaned glass sample <br /> containers. Hydrochloric acid was added as a pre2servac.ive. The <br /> samples were then sealed with Teflon-lined lids, labeled, and <br /> immediately placed in iced storage. <br /> Chain of custody Records for the water samples were initiated by <br /> the sampler and accompanied the samples to the analytical <br /> laboratory. Copies of the completed chain of Custody Records are <br /> included in the Appendix of this report. <br /> LABORATORY ANALYSES <br /> soil and water samples were delivered to Applied GeoSystems' <br /> i laboratory for analysis. Selected samples were analyzed .for <br /> total extractable hydrocarbons (TEH) , total volatile hydrocarbons <br /> (TVH) , the volatile hydrocarbon constituents benzene, <br /> ethylbenz_ene, toluene, and total xylenes, and for total <br /> 12 <br /> .dPp/ied GeQSystems <br />
