How does a drinking water test work?

Many people wonder how a drinking water test actually works. This overview shows the steps from the initial clarification to the test report.

Initial situation

Someone wants to know whether their own drinking water is OK, but is initially unclear about the procedure and the necessary scope.

Procedure

We start with a brief clarification of requirements: type of building, use, age of the installation, hot water system, visible abnormalities, odor, taste, stagnation, previous findings or special user groups. It is also important to determine whether it is a statutory obligation, a voluntary inspection, a specific problem or a preventive inspection. We then determine the scope of the test, followed by scheduling, sampling, laboratory analysis, plausibility check and evaluation of the results.

Result

You will receive a comprehensible test report. The general requirements and limit values must always be complied with at the outlet from the tapping point.
