How long does it take for blue-green algae to go away?
Most toxins are degraded within 2 weeks, but can be in the water at low levels for many months after a bloom forms.
What happens if you drink water with blue-green algae?
Algae-affected water may not be suitable for drinking, recreation or agricultural use. Contact with affected water can cause skin irritation, mild respiratory effects and hayfever-like symptoms. Ingesting toxins can cause gastroenteritis symptoms, such as vomiting, diarrhoea, fever and headaches.
