INTRODUCTION AND SCOPE OF WORK <br /> At the request of Mr. Allan Fetters, Advanced GeoEnvironmental, Inc. (AGE) has prepared this <br /> report of environmental activities conducted at 22871 South Highway 99, Ripon, California (the <br /> site). The location of the site and its surroundings are illustrated on Figure 1. Structures,monitoring <br /> well and remediation well locations associated with the site are depicted on Figure 2. <br /> ground water monitoring This report documents the ,performance of the quarterly gr g event on <br /> 22 July 2004. Background information, including details of previous site assessment work, is <br /> t presented in Appendix A. <br /> ' 2.0. PROCEDURES <br /> Quarterly ground water monitoring activities were conducted on 22 July 2004. Monitoring wells ' <br /> ' MW-1 through MW-5 were monitored and sampled. <br /> All field work was performed in accordance with Central Valley Regional Water Quality Control <br /> Board (CVRWQCB) guidelines for the investigation of underground storage tank (UST) sites. <br /> Ground water monitoring and sampling was performed in accordance with San Joaquin County <br /> ' Environmental Health Department (EHD) guidelines for the sampling of ground water monitoring' <br /> wells. <br /> 2.1. WELL MONITORING AND EVACUATION <br /> ' 'A Solinst water level meter was used to measure the depth to ground water in on-site wells MW-1 <br /> through MW-5 relative to the tops of the well casings. The total depth of each well was also <br /> measured, after sediment was removed from the well casing. The ground water elevations and <br /> ' gradient were determined from these data (Table 1). <br /> ' After recording water level measurements, disposable plastic bailers were used to purge the wells <br /> of standing water. Approximately 2.5 to 4 gallons of water(a minimum of 3 casing water-volumes <br /> per well) were removed from MW-1 and MW-3 through MW-5; well MW-2 was purged near-dry <br /> after 1 gallon of water was removed. ---� <br /> Ground water temperature,pH and conductivity were measured at regular intervals during purging <br /> using an Oakton water analyzer. Purged ground water was containerized in properly labeled <br /> 1. Department ofTransportation(DOT)-approved 55-gallon drums and was stored on-site.Field sheets <br /> and data are included in Appendix B. <br /> ' Advanced CeoEnvironmental,Inc. <br />
