• collect samples to confirm the vapor results. The results of the investigation were presented in the Soil Assessment Report prepared by Upgradient in April 1998 Subsequently, one of the borings was converted to groundwater monitor well VM-4 In August 1999, Upgradient installed two remediation test wells within the mapped zone of soil contamination However, no hydrocarbons were detected in any of the soil samples collected from these wells One of the wells (VT-1) was screened with 4-inch PVC casing from 15 to 30 feet for future use in soil vapor extraction testing The other well (SW-1), was screened with 2-inch PVC casing from 29 5 to 315 feet for potential use as an air sparging well 3.0 QUARTER ACTIVITIES 3.1 Purge Water Disposal Warren Gomes Excavating mobilized a vacuum truck to the site on July 27 and pumped approximately 350 gallons of purged groundwater from the 55-gallon drums that have accumulated at the site The water was transported to In-Strat, Inc , a water treatment and disposal facility in Davis, California, where it was treated and disposed of in accordance with In-Strat's permit A copy of the transport ticket is included in Appendix A i 3.2 Groundwater Monitoring i The depth to groundwater was measured and water samples were collected on September 28, 2000 The wells were opened and allowed to equalize with atmospheric pressure before the depth to groundwater was measured Depth measurements were recorded on the Well Monitor Report (Appendix B) and are shown in Table 1 After water depths were measured, a battery-operated bladder pump was used to purge the wells of standing water The wells were purged until conductivity and temperature stabilized or until the wells went dry(Appendix B) As in the past,the water purged from VM-2 was the color of "gray water", and a sewer odor was present Purged water was stored in a DOT-approved drum in the southwest corner of the site After purging, samples were collected from each well Two 40-m1 vials were collected from each, labeled, and placed in a cooled ice chest The samples were later transported to Excelchem Environmental Laboratory for analysis The laboratory report is included in Appendix C 4.0 RESULTS 4.1 Depth to Groundwater and Groundwater Gradient The depth to groundwater on September 28 averaged 32 feet (Table 1), which places the static water level at or slightly below the contact between the aquifer sand and the underlying clay bed At this depth, the water level is still 13 feet above the screened interval in VM-1, VM-2, and • 3
