Water Quality Data
It is estimated that about $142-168M is spent annually in Australia on monitoring water quality (Atech, 2000). This monitoring is undertaken by a range of Commonwealth, State or Local Government agencies, private companies, research groups and community-based groups, over a range of settings, the most significant being rivers and creeks, industrial effluent and reservoirs and lakes (refer Table 1). The most common reasons cited for monitoring water quality are compliance with health or environmental regulations, operational or process control, or for environmental or catchment health, with the most common parameters monitored being general physicochemical attributes (eg temperature, pH), nutrients, ions and pathogens (Atech, 2000). Table 2 outlines the organisations that undertake significant monitoring of water quality.
| Water Type Category | Number of Monitoring Programs | % of Programs |
|---|---|---|
| Rivers and creeks | 293 | 29 |
| Industrial effluent | 177 | 18 |
| Reservoirs and Lakes | 114 | 11 |
| Drinking water reticulation systems | 82 | 8 |
| Estuaries | 83 | 8 |
| Groundwater | 69 | 7 |
| Domestic wastewater | 68 | 7 |
| Coastal and marine waters | 46 | 5 |
National Land and Water Resources Audit (NLWRA)
At a national level, the Australian Water Resources Assessment 2000 (NLWRA, 2001) reported the level of significance of various water quality issues such as nutrients, salinity, turbidity and pH at a river basin scale. The analysis highlighted the catchments where monitoring was insufficient for undertaking exceedance or trend analyses. Other national assessments by the NLWRA associated with water quality and available from the ANRDL include:
- sediment and nutrient source, sink, load and delivery information compiled from the Water-borne Soil Erosion Project;
- reporting of the proportion of farms with significant land or water degradation problems at the Statistical Division (SD) level; and
- mapping of current and future dryland salinity hazard. These assessments were undertaken by State/Territory agencies using a combination of groundwater levels and trends, known salinity incidences, soil properties and topography.
Waterwatch
The Waterwatch initiative is a community-based water monitoring program designed to encourage local participation in catchment management. Over 300 community groups in 200 catchments are involved in the regular monitoring of about 5,000 sites across Australia, including physical and chemical testing. The program supports State-based facilitators and activities:
Waterwatch ACT
Waterwatch NSW
Waterwatch Queensland
Waterwatch South Australia
Waterwatch Victoria
Ribbons of Blue (Waterwatch WA)
Streamwatch is a similar public water quality network established around the Sydney metropolitan area and sponsored by Sydney Water .
This inventory provides public access to information on the types and amounts of 90 priority substances being emitted to the environment. It covers pollution emission data for about 3,000 facilities within 29 catchments across Australia.
At the State level, a wide range of water management, environmental protection and health agencies maintain water quality databases to service their regulatory, licensing or management activities (refer Table 2). The more significant of these databases relate to issues such as rural drinking water, sewage treatment plants, algal blooms, pesticides, agricultural waters, riverine sediment or salinity trends.
