It was <br /> supposed to be dry to 165 feet, then we were going to grout the hole back up, we just wanted core <br /> samples (no well was intended). They hit a zone of water at about 60 feet, which was a surprize, so we <br /> are installing a well at that location. We needed to complete the primary objective still of going to 165 <br /> feet and collecting core samples, so we moved over 5 feet and started drilling again. Yesterday, Frank <br /> did nothing with the shallow well, he just left the augers in the hole and let water seep into the boring <br /> while they started over on the 165 foot boring. This well is going to be called MW-29. <br /> Here are the construction spec's for the well and the boring: <br /> MW-29: <br /> Total depth=75' <br /> Backfill 1/4 bentonite TR 30 pellets=75-71' (2 buckets) <br /> Screen from 60-70 (0.01" SCH 40 machine slot) <br /> Sand from 71-58' (#2/12 clean sand 4X100 Ib bags) <br /> Transition seal from 58-56 (3/8 bentonite chips, 1 50 Ib bag) <br /> Surface seal from 56 - 0 (19 X 94 Ib bags portland type 1/II cement) <br /> Blank casing - 0 - 60 (SCH 40 PVC) <br /> Monument-4"X 5' steel, 3'above ground, 2' below ground (stovepipe monument) <br /> PDB-1: <br /> Total depth=160' <br /> Backfill plug from 160-137' (sealed off water zone at bottom, 1/4" bentonite pellets TR30. 14 buckets) <br /> Surface seal from 137-0 (45 bags cement, same type as above) <br /> Well Cluster 3 (WC3) is on Figure 19, in Study Area 2. 1 attached a map, but it should also be in the <br /> workplan. <br /> let me know if you need anything else. you say jump, I say how high. <br /> Dennis <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] <br /> Sent: Wednesday,June 11, 2008 10:17 AM <br /> To: Dennis Leikam <br /> Subject: WC-3 <br /> Dennis, <br /> I can't find the location of this well on any map... <br /> I found PDW-1 on parcel 251-320-06, but no WC-3... <br /> send me an updated map that shows WHERE this well is... <br /> no map..no issue. <br /> 6/11/2008 <br />
