Organic pollutants in fresh waters
Water analysis service providers measure organic pollutants on samples prepared by AGLAE. These analyses correspond to the monitoring of water intended for human consumption, swimming pool water and surface water.
⇒ AGLAE provides 32 programmes in this category of interlaboratory tests "Organic pollutants in fresh waters".
AGLAE estimates the analytical performance of participants, enabling them to improve the quality of their measurements on water.
Why participate in the "Pollutants in fresh waters" proficiency tests?
They are carried out as part of self-monitoring or regulatory controls. These tests cover some of the requirements of :
- accreditation scopes related to physico-chemical analyses in waters (see Accreditation No. 1-1664)
- approvals issued by Ministries of Health to carry out sampling and analysis for water quality control purposes
- approvals issued by Ministries for the Environment to carry out analyses in the field of water and aquatic environments
- the Water Framework Directive (WFD 2000/60/EC), which sets objectives for preserving aquatic ecosystems
What types of waters does AGLAE provide in these proficiency tests?
- continental surface water: lake, canal, pond
- drinking water: tap water, spring water, non-typical natural mineral water
What analyses do the laboratories carry out?
Participants analyse a wide range of organic pollutants, including:
- Volatile organic compounds (VOCs)
- Benzenes, toluenes, ethylbenzenes, xylenes (BTEX)
- Polycyclic aromatic hydrocarbons (PAHs), Polychlorinated biphenyls (PCBs)
- Pesticides and phytosanitary products (herbicides, insecticides, fungicides, etc.).
- Trihalomethanes (THMs)
Added value of AGLAE "Pollutants in fresh waters" proficiency tests
Depending on the methods used to analyse micropollutants, differences in results are observed. AGLAE studies them and presents them in the test reports. These observations help laboratories to better interpret their analysis results.
AGLAE has published several studies on organic pollutants studies on organic pollutants based on test observations:
- Method differences for organic micropollutants in clean water
- Reliability of the determination of chloroacetamide metabolites
AGLAE proficiency tests are used not only to assess laboratory performance, but also to check their estimated measurement uncertainties and to assess the repeatability and reproducibility of their measurements.
AGLAE provides personalised reports to laboratories, enabling them to focus on possible improvements to their analyses.
