In looking at the data you <br /> have provided, I have noticed that the depths of all probes have changed. In Figure 1, the design was <br /> submitted as: <br /> Depth of well: 69' <br /> Deep probe: 68' <br /> Inter. probe: 40' <br /> Shallow probe: 15' <br /> Did the encounter issues in the field to change the original design? Please let us know. <br /> Thanks.......Gino <br /> From: Natalia Subbotnikova [EH] [ma I Ito:nsu bbotn ikova@sjcehd.com] <br /> Sent: Monday, April 14, 2008 2:01 PM <br /> To: Yekta, Gino <br /> Subject: Installation of GW-1A(Corral Hollow Landfill) <br /> Hi Gino, <br /> Attached are the photos I took during GW-1A installation at the Corral Hollow Landfill on April 10-11, 2008. <br /> Installation went smoothly. Public Works used the design we previously approved. <br /> The depth of the well -69'. <br /> Deep probe pipe-50'6" <br /> Intermediate probe pipe-25'6" <br /> Shallow probe pipe-10'6" <br /> 20 lbs probe pipe weight was securely bound to the side of each probe. <br /> If you have any questions, please let me know. <br /> Thanks......Natalia <br /> 4/14/2008 <br />
