I was on vacation last week. <br /> Here's where we are with Tracy -we did get the 2nd hole (HP-7) in on January 3 -the seal was hydrated at 5:05. <br /> Visible water was observed at 5:15. Weather conditions were worsening, so the cement seal was tremied in <br /> place beginning at about 5:20. For HP-7, well screen was 15-30' bgs, top of sand pack at 12'0", top of fine sand <br /> at 11'6", bentonite chips (hydrated)to 9'6", portland cement to about 6" bgs, with concrete pad and protective <br /> casing. On Friday, January 4, conditions were terrible and no drilling occurred. The crash posts were set for the <br /> two existing wells. We are scheduled to install the 3rd well this Friday. I am meeting the drillers at 8:30. 1 <br /> wouldn't expect to be setting the seal sometime around 11:30. 1 can call you once we start drilling down with the <br /> larger augers to give you a better estimate. Let me know what you'd like. Fortunately, the weather forecast looks <br /> great for Friday. <br /> Thanks. <br /> Toni Pezzetti, PG, CHG <br /> CH2M HILL <br /> Phone (direct)916-286-0297 <br /> Fax(direct)916-614-3497 <br /> tpezzett@ch2m.com <br /> 1/18/2008 <br />
