TreadweIERollo <br /> • for soil sampling. Boring Logs are presented in Appendix B. Analytical results for soil are <br /> listed on Tables 1 through 4. <br /> Borings 11-B-18 and 11-B-21 were advanced to approximately 28 feet deep to obtain grab <br /> groundwater samples. Analytical results for groundwater are given in Tables 5, 6, and 7. <br /> 2.2.3 Area 20 <br /> On 19 April 2000, Spectrum drilling used their direct push rig to advance 9 soil borings at the <br /> locations shown on Figure 6. The borings were advanced to between 6 and 10 feet deep for soil <br /> sampling. Boring Logs are presented in Appendix B. Analytical results for soil are listed on <br /> Tables 1 through 4. <br /> On 19 April 2000, Blaine Tech Inc. sampled existing monitoring wells MW-2 and MW-3 under <br /> the supervision of Treadwell & Rollo personnel. Two groundwater samples were collected,plus <br /> • a trip blank, equipment blank, and duplicate. Monitoring well locations are given on Figure 6. <br /> Analytical results for groundwater are given in Tables 5, 6, and 7. <br /> 2.3 Field Investigation at Operable Unit 2 <br /> 2.3.1 Area 15 <br /> On 2 May 2000,AGE used Enviroprobe Drilling to advance 4 soil borings with their direct push <br /> rig at the locations shown on Figure 3. Treadwell & Rollo and DTSC personnel were on site to <br /> observe. The borings were advanced to between 1 and 15 feet deep for soil sampling. Boring <br /> logs prepared by AGE are presented in Appendix C. Analytical results for soil are listed on <br /> Tables 1 through 4. <br /> Boring 1513-8.0 was advanced to approximately 20 feet deep to obtain grab groundwater <br /> samples. Analytical results for groundwater are given in Tables 5, 6, and 7. There are currently <br /> 15 groundwater monitoring wells being sampled as part of an ongoing groundwater monitoring <br /> 21 <br /> 25970309.DGD 24 August 2000 <br />
