Drinking water hygiene

Testing under the German Drinking Water Ordinance

Microbiological drinking water testing under the German Drinking Water Ordinance (TrinkwV), within an agreed scope of testing.

Microbiological drinking water testing

Drinking water testing under the German Drinking Water Ordinance (TrinkwV) provides microbiological monitoring of drinking water samples within a defined scope of testing. Depending on the installation, its use and the specific enquiry, microbiological testing may be required or appropriate.

At our microbiological laboratory, we test drinking water samples within an agreed scope of testing. Possible microbiological parameters include colony counts at 22 °C and 36 °C, Escherichia coli, coliform bacteria, intestinal enterococci, Pseudomonas aeruginosa and Legionella spp.

The scope depends on the drinking water installation, the specific enquiry and applicable requirements. If needed, we can advise you on a suitable scope of testing.

Scope of testing

Parameters selected for the enquiry and installation

The parameters to be tested depend on the specific enquiry, the type of drinking water installation and the agreed testing objective. Suitable parameters are therefore selected for each individual investigation.

Depending on the agreed scope, microbiological testing may include indicator organisms, colony counts and other parameters relevant to hygiene. Further information on testing for Legionella spp. is available on our dedicated service page.

For selected parameters, such as certain heavy metals, sampling followed by analysis at a partner laboratory can be arranged.

Core microbiological parameters

Colony counts and indicator organisms

For testing of general microbiological parameters and indicator organisms relevant to hygiene.

Drinking water installations

Scope tailored to the installation

For enquiries where the type, use and layout of the drinking water installation need to be considered when selecting parameters.

Selected additional parameters

Individual arrangements

For investigations that may require selected additional parameters or analysis by a partner laboratory.
