History Well 29-4 <br />• August 1999 water quality sample collected from 29~U, 29-4A, and 29-4D <br />using dedicated gas displacement pumps. <br />• September 1999 water quality sample collected from 29-4U, and 29-4A, <br />using dedicated gas displacement pumps. No sample was collected from <br />29~D during September 1999 as a result of plugging from bicarbonate <br />precipitate in the sample return line. <br />• October~1999 water quality samples collected from 29-4U, and 29-4A, <br />using dedicated gas displacement pumps <br />-:~ ~ z <br />Notes ~~~~..~ ~ ~~'~_,~ s. ~ ~ ... ~. ~ ; _. <br />This borehole was planned to be a quadruple completion (29-dU, 29~A, 298, <br />and 29-dD). However, an excess volume of cement was inadvertently placed in <br />the annular space between the Dissolution Zone completion and the B Groove <br />completion, resulting in a cement plug in the B Groove completion interval. A <br />second borehole was eventually drilled on the same drill pad and completed as a <br />single B Groove well. The designation for this well is 29-46. Separate <br />completion diagrams are provided for this well. <br />• <br /> <br />
