On May 21, 2024, the European Union (EU) issued Commission Delegated Decision (EU) 2024/14411, introducing a methodology to measure microplastics in water intended for human consumption. The move comes as a supplement to Directive (EU) 2020/2184 on the quality of water intended for human consumption2, which empowers the Commission to adopt a methodology to measure microplastics with a view to including them on the watch list referred to in Article 13(8) of that Directive.
