EN ISO 19458: Water - Sampling for Microbiological Analysis

Drinking water or domestic water must pass many microbiological, physical and chemical tests, taking into account the health of the consumer. Water analyzes are carried out in accordance with many standards, regulations and communiqués.

The most important point in performing water analysis correctly is the sampling method. Especially the water samples taken for microbiology analysis should be sent to the laboratory without contamination.

Sampling procedures
- Personnel selection: Personnel selection is an important factor in water sampling for microbiological analysis. In particular, authorized and knowledgeable personnel should take appropriate samples.
- Sample containers: The containers or bottles to be used for sampling should be clean and sterile. The volume of the containers and bottles should be suitable for the sample to be taken for the analyzes to be made. The bag, sachet, paper or aluminum material in which the sample containers will be placed should also be sterile. The sterilization process to be applied must be suitable for the analysis to be performed. Covers to be selected for sample containers; it can be a frosted glass or plastic stopper for glass bottles, a plastic press-on cap for plastic bottles or jars, or a plastic or metal screw cap for both.
- Transport and storage: Collected water samples must reach the laboratory without contamination. Transport and storage should be done in a way that does not affect the analysis results.
