Water Quality

Ambient water quality

Water quality is a key indicator of aquatic ecosystem health. In western Moreton Bay and the lower reaches of the Brisbane River, water quality is predominantly affected by pollutants from catchment run-off and discharges of treated sewage.

In 2014, PBPL initiated a long-term water quality monitoring program to assess potential impacts of port operations on adjacent estuarine and marine environments. Water is sampled at numerous locations including the lower Brisbane River, Waterloo Bay, Outer Bar and Mud Island.

Data is collected by measuring multiple physical and chemical water quality properties using different equipment. Information gathered from this program is used to inform port planning and management activities.

Latest Research (at a glance)

  • The most recent ambient water quality monitoring was conducted in 2014.
  • Results found the lower Brisbane River area had poor water quality with turbidity, dissolved oxygen, pH and total phosphorus, copper and nitrate levels all exceeding water quality guidelines. Water quality in the lower Brisbane River is impacted by stormwater impacts from the entire Brisbane River catchment.
  • Waterloo Bay was found to be in in excellent condition as it is protected from discharges from Brisbane River, which are transported in a northerly direction due to predominant currents and flows.

Drinking water quality

Via the Queensland Urban Utilities’ water supply, PBPL is responsible and committed to maintaining the onsite potable water reticulation network to ensure zero harm to employees or the public. A detailed Drinking Water Quality Management Plan is in place as legislated by the Queensland Urban Utilities.
