O <br />I�WT <br />PACIFIC WESTERN MANAGES, LTD. <br />this well, 20 feet of filter pack sand was not possible on this well without deepening the hole. <br />The first solid limestone bed encountered, as indicated by a distinct change in drilling <br />characteristics (harder drilling), was from 373 -374 feet BGS. It is for this reason that the filter <br />pack could not he above 373 feet in the well. After consulting with CEMEX, an extra 3 feet of <br />transition sand was added to give an extra degree of protection to the screen from grout intrusion. <br />The fine transition sand was added from 373 -376 feet BGS. The well was grouted and <br />developed (see Drilling Timeline section), thc surface casing set, and thc protective pad <br />constructed. <br />If you require any further clarification or information, please contact Richard McPeek at 274- <br />5400, extension 23. <br />Sincerely, <br />PACIFIC WESTERN TECHNOLOGIES, LTD. <br />Dorthea Hoyt, PE, PMP <br />PWT Project Manager <br />Attachments: <br />Attachment A- Lithologic Borehole Log <br />Attachment B- Project Log Book Copies <br />Page 4 of 4 <br />
