Long <br />Division Dire<lor <br />A discussion was held of problems with the installation of ground water monitoring wells and the <br />initiation of the ground water monitoring plan. The following list summarizes the discussion anti the <br />possible resolution of each issue discussed. <br />1. The Uinta completion on well 21-4 suffered a casing failure and will be replaced with a single <br />completion monitoring well at the same location. A sample will be collected prior to 8/l/99. <br />2. The driller inadvertently cemented through the B-Groove completion In well 29-4. American Soda <br />will recomplete well 29-2 for B-Groove monitoring and will collect the 7/99 sample from this <br />recompleted well, then will drill a new single completion B-Groove well at 29-4 for collection of <br />the August sample. The recompleted well 29-2 will also be sampled in August and possible <br />September for correlation with 29-4 B-Groove data, then 29-2 will be abandoned and reclaimed by <br />10/l5/99. (29-2 well pad is in a poorly selected location at the confluence of two drainages, and is <br />being eliminated at the direction of the BLM). <br />3. Well 19-2 blew out during drilling when a gas pocket was intercepted in the saline zone. The <br />completion is suspect, and well may be yielding data that is not representative of the A-Groove, <br />e.g., elevated HAS. American Soda may abandon 19-2 and recomplete 20-4 for A-Groove <br />monitoring. <br />4. Well 20-4 has bentonite in the screen. American Soda may drill a new well for B-Groove <br />monitoring. <br />5. As a result of difficulties described in items 3 and 4 above, American Soda may not get the first set <br />ofcross-gradient A-Groove and B-Groove samples until August 1999. <br />cc: Max Ramey, American Soda (vin fncsimife) <br />Paul Daggett, BLM (vir~ facsimile) <br />
