Bushfires pose serious short- and long-term impacts to public drinking water quality. They can damage water supply infrastructure and water catchments, impeding the treatment processes that normally make our water safe to drink.
Several areas in New South Wales and Victoria have already been issued with warnings about the quality of their drinking water.
Bushfires can damage or disrupt water supply infrastructure as they burn. And the risks can persist after the fires are out.
Bushfires can damage drinking water catchments, which can lead to longer term threats to drinking water. Drinking water catchments are typically forested areas, and so are vulnerable to bushfire damage.
