[Drinking water analysis for Legionella. Suggestions for sampling, laboratory analysis and assessment].
Drinking water analysis for Legionella from building installations is done quite frequently. Some questions arise from experience with this analysis. They will be discussed to allow uniform and comparable execution. Application of DIN EN ISO 19458 will lead to changes in the sampling procedure. This may make changes necessary even in current sampling and assessment programs. Concerning laboratory investigation, quality control of membrane filters and media turned out to be crucial. The assessment of quantitative results requires knowledge of the drinking water distribution system and of other facts that may be relevant for hygiene. Therefore, the assessment ought to be conducted by somebody with the respective knowledge.
