INTRODUCTION At the request of Mr Robert McCarty,Advanced GeoEnvironmental, Inc (AGE) has prepared this quarterly report for the property located at 2420 West Turner Road, Lod;, California The scope of work included performance of a quarterly ground water monitoring event and preparation of this I report The site and the surrounding area are illustrated in Figure 1 On-site structures and monitoring well locations are illustrated on Figure 2 Site Background information is summarized in Appendix A 2.0. PROCEDURES Fieldwork was performed in accordance with guidelines established by the Central Valley Regional p Water Quality Control Board(CVRWQCB)for the investigation of underground storage tank(CYST) r sites lie 2 1 WELL MONITORING AND PURGING ' On 07 July 2003, the depth to ground water in all eight monitoring wells was measured from the top of each well casing to the nearest 0 01-foot utilizing a Solinst water level meter Ground water elevation in each well was calculated by subtracting the measured depth to ground water from the ' surveyed casing elevation (Table 1) After recording water level measurements, dedicated disposable plastic bailers were used to purge ' the wells of standing water Approximately 6 0 to 8 0 gallons of water(a minimum of 3 casmg-water volumes per well)were removed from wells MW-1 through MW--8 Ground water temperature,pH and conductivity were measured at regular intervals during purging using an Oakton water analyzer I Field sheets and data are included in Appendix B Purged water was stored in properly labeled DOT- approved model 17H 55-gallon drums and stored on-site 2 2 COLLECTION AND ANALYSIS OF GROUND WATER SAMPLES ' Water samples were collected from each purged well using new disposable plastic bailers after allowing the wells to achieve a minimum 80% recovery of the pre-purge water volume Each water ' sample was transferred into one 1-liter amber bottle without sample preservative and into three 40-m1 volatile organic analysis (VOA) vials containing 0 5 ml 18% hydrochloric acrd as a sample . preservative After collection, the samples were properly labeled, placed in a chilled container and transported under chain-of-custody to Cal Tech Environmental Laboratories (CTEL), a California Advanced GeoEnvironmental,Inc
