Water quality audit of Rose Bay and Terrigal region

The Department of Planning, Industry and Environment (the Department) Beachwatch program monitors and grades recreational water quality in accordance with the National Health and Medical Research Council’s (2008) Guidelines for Managing Risks in Recreational Waters. Long-term testing measures the impact of pollution sources at the swimming site and highlights areas of poor water quality and where further investigation is needed.

Rose Bay and Terrigal beaches are routinely graded as Poor in the Beachwatch program's NSW State of the Beaches report.

Beachwatch program monitoring is not  comprehensive enough to show the scale or extent of the water quality problem, nor the source of microbial contamination. To discover this, a more comprehensive audit is needed.

The Department worked with Woollahra Council and Sydney Water and with the Central Coast Council to investigate and report on the extent and source of poor recreational water quality issues in these areas to ensure the right solutions are delivered.
