The GHURA-Dededo Deep Monitoring Well: Planning and Design

The final design of Guam's first deep monitoring well has evolved from an open borehole concept through a three-well system ... to the present one-well system, [which] utilizes an inflatable packer assembly that will permit the accomplishment of several goals:

  1. Observation and simultaneous recording of point-water heads at two different levels
  2. Collection of water samples from isolated aquifer intervals
  3. Definition of a depth-salinity curve from the water column in the monitoring well

Although the one-well system is presently under construction, the design process is still continuing. A satisfactory method for emplacing and sealing the casing is still being worked out. Also, the precise location of the alternating perforated and sealed casing intervals must be determined.
