The appointed office for the testing of drinking water

Independent and accredited

We are the accredited and appointed office for drinking water in North-Rhine Westphalia. This certification was granted because we meet all requirements of § 15.4 of the Drinking Water Ordinance 2001 which was verified by the competent supervisory authority.

Requirements for recognized tests

We work independently and are not subject to any outside instructions regarding our work. Therefore, our results are fully recognized and provide you with the necessary security.
