Comparative sampling of groundwater

The comparative sampling of groundwater is a suitability test that is mandatory for all accredited institutions (testing laboratories and engineering offices) in the field of groundwater, provided that the aptitude test is technically correct and economically justifiable for the institution.

Participation in the comparative sampling of groundwater serves as proof of the aptitude to the client and the accreditation body. It can also serve as a basis for determining the uncertainty of sampling, as required by DIN EN ISO/IEC 17025:2018.

As a competent institution, the DGFZ e.V. has been regularly offering these comparisons for the sampling of groundwater under real conditions since 2018.

Each participating institution receives an on-site appointment in Dresden (time approx. 1/2 day). When registering, the calendar week for the on-site appointment is selected. The specific day and time will be assigned to participants after the registration deadline, but suggestions will be accepted and considered if possible.
