May 29, 1987 AGS 87050-1 <br /> USA Station #65, -Lodi, California <br /> WATER SAMPLING <br /> Ground water will be allowed to recover to static conditions and <br /> an initial water level measurement will be made. A bailer will <br /> be then used to obtain a sample from the surface of the water in <br /> the well. Any subjective evidence. of product detected in the <br /> wells will be recorded. If floating product is encountered in a <br /> well, the well will not be purged or sampled. If no floating <br /> product is observed in a well, a formation water sample will be <br /> collected after the well is purged. The well will be purged of <br /> at least three well volumes and sampled using a teflon bailer <br /> that is cleaned with acetone and rinsed with tap and deionized <br /> water. <br /> The water samples will be sealed in E.P.A. -approved, laboratory- <br /> cleaned 40 ml glass vials with teflon-lined lids, labeled, and <br /> immediately placed in iced storage. A Chain of Custody form will <br /> be initiated by the sampler and will accompany the samples to <br /> Applied GeoSystems ' analytical laboratory. A copy of the Chain <br /> of Custody form will be included in our final report. <br /> soil samples selected for testing will be analyzed by EPA Method <br /> 8020 (Benzene, Toluene, Ethylbenzene, Xylenes) and Total Volatile <br /> Hydrocarbons (TVH) ; water samples will be analyzed by EPA Method <br /> 9 <br /> ARRIied GeoSystems <br />
