Pollution from the production and use of PFAS in various products has led to the detection of PFAS and PFOS in the environment, and ultimately ground water, surface water, and drinking water across Europe. To address PFAS pollution, the European Chemicals Agency (ECHA) published a proposal to ban PFAS in February 2023. The Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) restriction proposal, authored and submitted by the Netherlands, Germany, Sweden, Norway and Denmark, addresses the manufacture, marketing (including import), and use of PFAS, including as constituents in other substances, mixtures, and articles above a certain concentration.
Though guideline values for PFAS in drinking water have existed in some countries for a number of years, the EU's revised drinking water directive (EU 2020/2184; DWD) is driving broader implementation and enforcement of PFAS testing across member states. As of September 2023, the EU list contained 24 target PFAS in water, including compounds which are suited to both LC and GC testing methods. When the revised EU Drinking Water Directive requirements for PFAS took effect in January 2024, the European Commission was expected to establish the technical guidelines for testing, including maximum concentration. In the United Kingdom (UK), the Drinking Water Inspectorate (DWI) has set forth requirements for 47 PFAS in drinking water in its DWI Information Letter 05/2021.
Agilent solutions for PFAS analysis in water help meet global directive and guideline requirements while also providing robustness and easy maintenance.
