Those type probes use sand and hydrated and non- <br /> hydrated bentonite granules and quarter inch tubing. Nightmares to remove/seal-destroy. <br /> the Geoprobe method is ok. <br /> are you sure the 3.25 rods (3.25 inch?)diameter is correct? hard pushing that diameter.... <br /> in the future include this info in the work plan...diagrams help too. <br /> I'll process today. I will be onsite for the first grout. Have the field tech call me day of the first hole to verify times. <br /> OK to page me at (209) 982-8771 if I don't answer my phone. <br /> I'll bring a copy of the permit for you with me on day one. <br /> From: Sobieraj, Justin J.

Please let me know if you need additional clarification. <br /> 1- how long will the probes be in the ground? do you plan to keep them in until lab data comes back? <br /> well-head protection during the interval??? <br /> These are temporary borings/probes (using a Geoprobe PRT- <br /> http://www.geoprobe.com/products/tools/soiI_gas/prtdesc.htm). The borings/probes will only be in the <br /> ground during the sampling period (approximately 1 hour), the rod will be then retracted and the boring <br /> abandoned. <br /> 2- how do you plan to construct them? get me a schematic/side view of construction spec, complete with <br /> materials, depths to each, etc.) <br /> The borings/probes are temporary (3.25 rods and a disposable sampling tip). The depths are as follows: <br /> Boring Location Sample Depth(b s) <br /> B2-A 14 <br /> B2-B 5, 10, and 15 <br /> B3-A 25 <br /> B3-B 5, 10, and 15 <br /> B6-A 11.5 <br /> B6-B 5, 10, and 15 <br /> B&A 11 <br /> 8/28/2007 <br />
