Also, approximately 200-feet due west of PDW-1(S)we advanced to 20 feet before I realized we may not be in the right position for the borehole, so it was grouted to surface and abandoned. The hole was re-started 200 feet east, as PDW-1(S). I attached a map that shows the location of the wells and abandoned borehole (sorry about that). Here are the spec's: 20-foot boring - Terminated at 20-feet. Grouted to surface using 6 bags of Type 1/11 Portland cement. WC-3 - Total boring depth = 44.5 feet Screen - 0.010" SCH 40, from 28-43' Sand -#2/12 Clean Sand, from 26-44.5' (6 X 100 lbs bags) Transition Seal - 3/8" Bentonite chips, from 24-26' (1 - 50 Ib bag) Grout- 8 bags of 94 Ib Type 1/II Portland Cement 7.5 gallons water used for hydration of transition seal, allowed 35 minutes of hydration time. PDW-1(S) Total boring depth = 52 feet Backfill - 1/4" bentonite pellets, TR30 (14 buckets) Screen - 0.010" SCH 40, from 8-23 Sand -#2/12 Clean Sand, from 7-24' (6 X 100 lbs bags) Transition Seal - 3/8" Bentonite chips, from 6-7' (1 - 50 Ib bag) Grout - 3 bags of 94 Ib Type 1/11 Portland Cement As for future drilling, we are done for this week, but Frank might be back out on Monday to start the PDW-1 (shooting for deep GW) with mud rotary. The well above, PDW-1(S) is installed in a shallow zone that is not the original target zone, but everybody agreed that they would like a well in first encountered GW in addition to the deeper zone. I will keep you posted, but even if Frank does come out Monday, it will be at least a few days before he's ready to grout a conductor casing. Thanks, give me a call or shoot me an email if you have any questions. Dennis 6/18/2008
