INTRODUCTION <br />' At the request of Mr Peter Lenz of Innovative Beverage Brokers,Advanced GeoEnvironrnental,Inc <br /> (AGE) has prepared this quarterly report for the property located at 1.648 Shaw Road, Stockton, <br /> California The site and the surrounding area are illustrated in Figure I Structures, boring and well <br />' locations are illustrated on Figure 2 Site background information is provided in Appendix A <br />' 2.0, PROCEDURES <br /> Field work was performed in accordance with guidelines issued by San Joaquin County <br />' Environmental Health Department (EHD) for the sampling of ground water monitoring wells and <br /> Central Valley Regional Water Quality Control Board (CVRWQCB) guidelines for investigation <br />' of underground storage tank (UST) sites <br />' 2 1 WELL MONITORING AND EVACUATION <br /> On 05 February 2003, a Solmst water level meter was used to measure the depth to ground water <br />' in monitoring wells MWI through MW7 relative to the tops of the well casings Depth <br /> measurements were not possible in wells MWI through MW3 because these wells had no <br /> measurable water(Appendix B) Consequently, these wells could not be purged or sampled Field <br /> sheets and data are included in Appendix B <br /> After recording water level measurements, dedicated disposable plastic bailers were used to purge <br />' wells MW4 through MW7 of standing water Approximately 0 5 to 1 5 gallons of water were purged <br /> from MW4 through MW7 Ground water temperature, pH and conductivity were measured at <br /> regular intervals during purging using an Oakton water analyzer Purged water was stored on-site <br />' in labeled, 55-gallon DOT-approved drums Field sheets and data are included in Appendix B <br />' 2 2 COLLECTION OF GROUND WATER SAMPLES <br /> A water sample was collected from each purged well using the dedicated disposable bailer after <br /> allowing the wells to achieve a minimum 80%recovery of the pre-purge water volume Each water <br /> sample was transferred into three 40-m1 VOA vials containing 0 5 ml 18% hydrochloric acid as a <br /> sample preservative and into one I-liter amber bottle without added preservative After collection, <br />' the samples were properly labeled, placed in a chilled container and transported under chain-of- <br /> custody to Cal Tech Environmental Laboratories(CTEL),a Department of Health Services-certified <br /> laboratory The ground water samples were analyzed for <br /> Advanced GeoEnvironmental,Inc <br />
