Apply for approval as a water testing centre

If you want to carry out investigations as a water testing body on behalf of the authorities or for self-monitoring or self-monitoring (e.B. as part of wastewater and raw water control), you must apply for approval (notification).

You can obtain approval as a water testing body for the investigation areas of wastewater, surface water as well as groundwater and raw water.

Sub-areas are:

1. sampling and general parameters;

2. Photometry, ion chromatography, dimensional analysis,

3. Elemental analysis,

4th/5th group and sum parameters,

6. Gas chromatographic methods,

7. HPLC procedure,

8. Microbiological processes

9.1 Biological processes, bioassays (Part 1) and

9.2 Biological processes, bioassays (Part 2).

Approval for an area of investigation requires proof of competence for sub-area 1 and for at least one further sub-area in this area of investigation. Competence must be proven for at least 2/3 of the listed parameters of the respective sub-area. This criterion applies only to sub-areas with more than two parameters.

A simplified approval procedure applies to the approval "Sampling in Schleswig-Holstein".
