Anom Ind

Indicates (Y/N) a subjective judgement that the water level or salinity reading is anomalous.​


Under Graph Filter, click the Anomalous check box to include or exclude anomalous readings from the graph and calculations.​

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.
Collect By

Identifies who collected the water sample, if available​

Collect Date
The date on which the water sample was collected for analysis.
Data Source

Code identifying the group or agency who collected, or was responsible for, the collection of the record. Applies to Water Level, Salinity, Well Yield and Water Chemistry records.

See Data Source Codes on the Code Definitions page.

Extract Method
A unique code indicating the method by which water was extracted from the well.
See Extraction Method Codes on the Code Definitions page.
Graph Filter

Use the following options to ​filter the points on the graph:

  • EC or TDS: Toggle between EC and TDS values (Salinity only).
  • Date: Type start and/or end dates in the format dd/mm/yyyy.
  • Value: Type minimum and/or maximum water level or salinity values according to the relevant graph.
  • Anomalous: Show/hide anomalous readings.
  • Pumping: Show/hide pumping readings (Water Level only).
  • Filter options are applied dynamically, as soon as you tab or click away from the field.
Join Points
Click to join the points on the graph. Note that some wells have significant time gaps between readings and this may lead to misinterpretation of trends.
Measured During

Code identifying the activity during which the measurement was recorded. Applies to Water Level, Salinity, Well Yield and Water Chemistry records.

See Measured During Codes on the Code Definitions page.

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.
A measure of the acidity/alkalinity of the water sample
Available when multiple wells are found. Click to navigate to the details of the previous or next well.
Sample Type
Code identifies the category of water sample.
See Sample Type Codes on the Code Definitions page.
TDS (mg/L)
Measured Total Dissoved Solids of the water sample recorded for the water well.
The Summary details shows only the latest observed value and date.
Test Place
Code identifying the location where the sample was tested.
See Test Place Codes on the Code Definitions page.
Unit Number

​First component of the Unit Number is a unique number for the 100,000 map sheet on which a drillhole is located.

Second component of the Unit Number is a unique number identifying the drillhole on the 1:100,000 map sheet
