A code or concatenation of codes identifying the aquifer(s) in which a water well has been completed. See Aquifer Monitored Codes on the Code Definitions page.
Identifies the class (or type) of the well. A well may have multiple classes. See also Well or Monitoring Point Classification Codes on the Code Definitions page.
Depth From/To

Describes the start and end of an interval in the well, measured in metres. Depending on the current view, this may relate to:

  • Drilling method
  • Construction casing and production zone
  • Hydrostratigraphic samples
  • Lithological samples
  • Stratigraphic samples
  • Water chemistry samples
  • Water cut (construction).
Name of the well, if available.
Also shown on the Water Chemistry tab as the name of the chemical (analyte) corresponding to the chemical code.

Code identifying one or more observation networks to which the well is associated, if applicable.​

Obswell No.

Unique code identifying the water well as ​an observation well, i.e. monitored for water levels. An observation well is associated with the relevant Obswell Network.

Not all water wells are observation wells.

Permit No.
Well construction permit number applicable to the drilling/contruction activity.
The Summary details show only the last permit number issued.
