Program start date

January 1960

Program end date

Ongoing

Objectives of the program

The program aims to:

  • collect ambient water quality data (both high and low flows) at a selection of Department of Environment and Resource Management gauging stations
  • assess and report on the condition and trend of Queensland’s freshwater aquatic ecosystem health.

Who is involved?

Lead organisation

Department of Environment and Resource Management

Contact details of lead organisation: water.custodian♲derm.qld.gov.au

Partner organisations

Queensland Health Forensic and Scientific Services (notional program for analysis of manual samples)

List of indicators monitored

Manual sampling at all sites:
General parameters – major Ions
Unfiltered nutrient samples – total nutrients (total phosphorus and total nitrogen)
Filtered nutrient samples – speciated nutrients (orthophosphate, oxidised nitrogen, ammonium)

In-situ (on-site) sampling at all sites:

  • Dissolved oxygen
  • Electrical conductivity at 25 °C
  • pH at 25 °C
  • Turbidity (Nephelometric Turbidity Units)
  • Total alkalinity

Continuous time series measurements at a subset of sites:

  • Electrical conductivity at 25 °C
  • pH at 25 °C
  • Turbidity
  • Temperature

Scale of program

Statewide

Brief description of sampling locations

There are a total of 196 Surface Water Ambient Network (SWAN) sites. A spatially balanced approach to SWAN site selection across Queensland is currently implemented. The sites were selected based on end of system, trend analysis and/or reference condition value. 

Frequency of monitoring

Samples are collected at either one, three or four month intervals depending on the site.
