Drinking water

Drinking water is the most important food product of all. It cannot be replaced. (Introduction and guiding principle of DIN 2000.) In the German-speaking world, the quality requirements for drinking water are higher than those for industrially packaged mineral water and bottled water. It is the food product that has been subjected to the most research. In Germany, drinking water’s quality requirements are set out in the Infection Protection Law (IFSG), the Drinking Water Ordinance (TrinkwV) as well as in various generally recognised technical regulations (DIN, DVGW and others).

Drinking water is defined as being water used for drinking, cooking, preparing food and drink or which is particularly intended for the following household uses (see section 3 of the TrinkwV):

  • Bathing and personal hygiene
  • Washing objects that are intended to come into contact with foodstuffs (glasses, tableware, cutlery)
  • Washing objects that are intended to come into prolonged contact with the human body (clothes, laundry)

Drinking water is fresh water whose purity is so high that it is suitable for human consumption, especially for drinking and preparation of food. Water for human consumption must be such that its use or consumption should not be injurious to human health, especially by pathogens (section 37 (1) IFSG). Many of the parameters that we can assess for you are set out in the TrinkwV. Of especial importance, and therefore regularly examined, are microbiological parameters and metals including:

LegionellaEnterococciLeadCopper
Colony count 22°C/36°CPseudomonas aeruginosaCadmiumManganese
Escherichia coliClostridium perfringensChromeNickel
Coliform bacteriaIron


We offer the complete range of tests on water, from acryalamide via volatile halogenated hydrocarbons, MOH, PAC, pesticides and THM to vinyl chloride and various special tests. You can find more information in our
download area . It also contains more information on the German Drinking Water Ordinance.

Legionella

Legionella tests are carried out in accordance with ISO 11731/the German Federal Environment Agency, and currently require 10 days. However, with the real-time PCR method, an informative assessment of a possible legionella contamination can be undertaken in advance.

For more information on this topic, our regularly trained staff would be pleased to assist.
