Specifies a method for isolating and estimating the number of Legionella pneumophila and a range of other Legionella spp. in water. This method is applicable to all water samples, including recreational, industrial, waste and natural waters.
This Standard is suitable for the testing of treated and untreated water samples. If low levels of Legionella spp. are anticipated in a water sample, AS 5132, Waters—Examination for Legionella spp. including Legionella pneumophila—Using concentration, may be more appropriate.
The sample of water is cultured on specified media directly as well as after heat and acid treatments. Presumptive Legionella colonies are taken through confirmation tests. Confirmed Legionella isolates can be speciated and serotyped as required.
