The reuse of treated wastewater (REUSE) is still underdeveloped but appears to be a solution for improving quantitative water management. Nevertheless, there is a health risk associated with REUSE even when wastewater is very well treated, mainly due to residual microbiological pollution.
Besides, as part of your accreditation, participation in interlaboratory tests for Salmonella detection may be requested per matrix (fresh waters, waste waters, saline waters).
In this context, AGLAE invites you to participate in an interlaboratory test where the ability to detect Salmonella in waste water (programme 37A) and another one in saline waters (programme 37B)  will be assessed.

Following its success in 2025, AGLAE provides again laboratories with an interlaboratory test regarding the use of Integrative Passive Samplers for the monitoring of metals in fresh waters.

In the frame if this proficiency test, laboratories will be assessed for the measurement of 9 metals with DGT samplers (CHELEX chelating resin).

Check the DGT flyer for more information (DGTs sent on May, 4th 2026).

To participate in this test, register promptly. Limited number of participants

Should you already have participated in our tests, contact us. 

You may register at any time during the year as long as registration deadlines are not over.

For a first participation, please complete the form on the  Contact page to get a quote.

- In fresh waters and waste waters (programmes 59 "Perfluorinated compounds in fresh waters" and 59A "Perfluorinated compounds in waste waters") : 9 PFAS and 2 US PFAS are added to the PFAS  already provided in order to meet the requirements of the Water-Framework Directive. For each PFAS (except TFA and TFMS), participants will be able to report results for the linear isomers but also for the sum of linear and branched isomers.

- In sediments and soil: new programmes 48 "Perfluorinated compounds in solid matrices" with the quantification of 21 PFAS

Find the descriptions of these programmes on the pages organic pollutants in clean waters, organic pollutants in waste waters and chemistry in solid matrices

 ISO/Technical Committee 147 "Water quality" will meet in Pretoria from the 13th to the 18th of April 2026.

AGLAE will participate to bring its technical and statistical expertise in the water quality field.

See you there
