Water quality

Man accessing water quality

We are responsible for the protection and enhancement of the natural environment through the preservation of water quality and the promotion of water conservation and re-use. We do this through catchment planning and ensuring we make informed decisions based on data we collect from monitoring of our waterways.

Monitoring water quality informs us on the health of our local waterways. We regularly sample and monitor 16 sites within 13 waterways across Blacktown City. We conduct physical and chemical monitoring, as well as monitoring of the diversity of the waterbug (aquatic macroinvertebrate) communities and the condition of riparian vegetation.

Physical and chemical

The physical and chemical components of water quality are important factors of aquatic ecosystem health. We measure pH, salinity, nutrients and turbidity.

Waterbugs (aquatic macroinvertebrate)

Our monitoring includes assessing the presence of waterbugs (or aquatic macroinvertebrates) as they form an important part of the aquatic ecosystem. They are widely used as indicators of waterway health. Certain waterbugs are more tolerant to water pollution and environmental change than others. By monitoring the waterbug communities we gain more of a snapshot of current waterway health.

Riparian vegetation

Native riparian vegetation along creek banks is beneficial to maintaining water quality, bank stability and regulating water temperature. It also provides important habitat and a major role in the food chain of creek ecosystems.
