Water quality - Enumeration of Legionella (ISO 11731:2017)
ISO 11731:2017 specifies culture methods for the isolation of Legionella and estimation of their numbers in water samples.**These methods are applicable to all kinds of water samples including potable, industrial, waste and natural waters. These methods can be used for water related matrices, e.g. biofilms, sediments, etc.**Not all Legionella species are culturable; therefore, the methods described in this document do not recover all species of Legionella.
