Hello Mavis,
The sonar jetting has been conducted at EW-3, EW-8, and EW-13. Pumping has resumed at EW-3 and EW-8; however, pumping at EW-13 has been postponed until the well can be redeveloped. When the pump at EW-13 was pulled, debris from the previous years jetting was observed in the pump inlet which we believe has decreased the pumping rate. Prior to reinstalling the pump, we want to redevelop the well and remove the accumulated sediment/debris. Redevelopment of EW-13 is scheduled for Wednesday (August 2nd).
Thank you,
Christine Kimmel, L.G.

Mavis,
FYI, TSA remedy extraction wells EW-3, EW-8, and EW-13 will be sonar treated next Wednesday, July 26 by Waterwell Developing (Umatilla, OR), as part of our annual sonar cleaning program. So they will be brought offline sequentially, beginning July 24 to remove the pump assemblies for Wednesday’s downhole cleaning. The pumps will be reinstalled on the July 26 and 27 for resumed operation. We’ll document the down time and sonar cleaning events in the quarterly data report, but wanted to notify you ahead of the cleaning event.
Thanks. –Sarah
