Abstract
The microbiological quality of 49 South Australian spa pools was assessed, using as criteria the presence or absence of Pseudomonas aeruginosa, the colony count, and the presence or absence of amoebae. Chlorine was the disinfectant most frequently used (with or without cyanuric acid), followed by bromine. The microbiological quality of water samples did not vary by disinfectant mode, except for samples from pools using cyanuric acid which gave poorer results for amoebae. Where chlorine alone is used for disinfection, results indicate that a free chlorine residual of at least 4 mg 1-1 is necessary to be 95% sure of acceptable microbiological quality.
