Water Quality

Amoebic meningitis is a rare but fatal infection caused by the Naegleria fowleri amoeba which lives in fresh water and damp soil. When water containing active amoebae enters the nose, the amoebae travel to the brain causing inflammation and destruction of brain tissue.  For tips on ways to keep safe in the water, visit HealthyWA.
