AnswerView source ↗
I thank the member for some notice of this question.
(1) Chlorine is
the only chemical added to the water to achieve a residual chlorination level
of 0.5 milligrams per litre. This is consistent with the Australian Drinking
Water Guidelines.
(2) Naegleriafowleri
and Naegleria lovaniensis are closely related thermophilic amoebae.
Naegleriafowleri causes primary amoebic meningoencephalitis, a rapidly fatal
disease of the central nervous system, while Naegleria lovaniensis is
non-pathogenic. Busselton Water undertakes weekly testing for Thermophilic
Amoeba and Naegleria lovaniensis has previously been identified.
