ANOTHER ROUND OF PROFICIENCY TESTING COMPLETED! THANK YOU FOR YOUR PARTICIPATION!

On June 9 and 10, 2026, we conducted two further rounds of proficiency testing in the field of surface water sampling – rivers/streams and lakes/artificial reservoirs (Wr and Wj). On the first day – round 59(Wr)PP – the tested site was the Vistula River, while round 60(Wj)PP took place the following day at one of the artificial dam reservoirs.

We would like to sincerely thank all participants. Thanks to you, we gain new experience and ideas for improving our services.
