Pool reopens with clean bill of health
■ Exmouth Swimming Pool was closed twice in one week after micro-organisms were discovered in water samples.
The pool reopened on Monday after laboratory analysis came back to confirm no harmful organisms were found in the water.
Shire of Exmouth executive manager Rob Manning said they super-chlorinated the pool as a precautionary measure to ensure it would be open to host 130 swimmers at the Gascoyne Open Swimming Championships this coming weekend.
The pool initially closed on October 23 when routine sampling detected the presence of thermophilic Naeglaria in the toddler’s pool.
Mr Manning said there were many different species of Naeglaria but only one, Naeglaria fowleria, was known to be harmful to humans, causing amoebic meningitis.
As soon as Naeglaria is found in a pool sample, procedures require the pool to immediately close while species identification takes place.
“In this case the laboratory analysis has confirmed that the species of Naeglaria detected in the sample was not Naeglaria fowleria and was of no risk to human health,” Mr Manning said.
He said samples from the other two pools in the complex were completely free of any organisms, but all three pools form one water body.
Following these results the pool reopened on October 29, but had to close again the following morning when a second suspect organism was detected in the pool water.
Mr Manning said the worst case scenario would have been the organism was identified as one that required the pool to be super-chlorinated, so the Shire decided to go ahead with the procedure anyway.
Thermophilic Naeglaria can enter into a pool through wind-blown soil and dirt, and appears when water temperatures range between 28C and 40C.
“At this time of year, when the wind starts to blow, it’s not uncommon for at least one of the public pools in town to return a positive result to a thermophilic Naeglaria, but very uncommon for the town pool to do so,” Mr Manning said.
