Sewage dropped on homes near bushfire
Residents have had sewage wastewater dropped on their properties by firefighting aircraft as the blaze threatened lives and homes near Perth.
Authorities warned people in part of Bullsbrook about 35km from the Western Australia capital, that they could be at risk and issued a hazardous and toxic materials alert.
“During bushfire suppression operations to protect the Bullsbrook College and surrounding propertie, helicopters drew from water sources that have been identified as sewage wastewater holding ponds,” the Department of Fire and Emergency Services said on Thursday.
Authorities urged residents not to be alarmed and said the forecast high temperatures in the area into the weekend would help neutralise any residual bacteria contained in the effluent.
“No buildings were directly targeted during bushfire suppression activities but properties surrounding the bushfire area may have been impacted by some aircraft drift spray,” the alert said.
Premier Roger Cook said an investigation would be launched into the incident.
“On this particular instance (the helitankers) accidentally drew water from a holding pond in a wastewater treatment facility,” he said.
“Our priority is to keep people safe and to get the fires out and in an emergency situation sometimes it doesn’t always go to plan.”
He said the effluent was dropped on bushland and drift spray may have landed on homes and properties.
“We are just responding from the abundance of caution,” he said.

The bushfire, which has threatened lives and homes near Royal Australian Air Force base Pearce, continues to burn but it has been contained and controlled.
The Department of Defence confirmed the ponds the sewage wastewater was drawn from are fed from reticulated water supply and do not have any PFAS chemicals present.
Residents in the affected area who have water tanks for household use have been urged to empty their tanks and hose down structures and vehicles if they have been contaminated.
People with vegetable gardens or fruit trees have been told not to harvest crops for two days and thoroughly wash any produce before consumption after this period.
