Bushfires generate large quantities of ash and debris which have the potential to contaminate water.


Although ash and debris in rainwater does not represent a health risk, it could affect the colour, the clarity and the taste of the water. The SA Health Water Quality team is available to answer questions during business hours. Phone 8226 7100

Dams and waterways

Ash from burnt permapine (CCA timber, treated with copper, chromium and arsenic), is hazardous to livestock if significant quantities get into your dam or waterways.

Free water quality testing is available for people who have concerns a significant amount of this ash impacting the water quality of their dams or waterways.

Details on how to collect a water sample from your dam or waterway, and strategies on how to improve your water quality, are available in this EPA fact sheet.

Blue-green and other algal outbreaks

The Department of Primary Industries and Regional Development (WA) has some simple control methods for algae.
