Microplastics – Drinking Water – Standardized Analytical Methods Adopted by California State Water Board

A December 6, 2021 California State Water Board news release https://www.waterboards.ca.gov/press_room/press_releases/2021/pr12062021_microplastics_standardized_method.pdf reports that “… the State Water Resources Control Board, in partnership with the Southern California Coastal Water Research Project, has developed the first standardized analytical methods … for the testing and reporting of microplastics in drinking water … Development of the new standardized methods – Raman spectroscopy and infrared spectroscopy … allow environmental laboratories to conduct tests and post findings that will be comparable with other labs that are following the same protocols … Testing will initially focus on source waters – rivers, aqueducts and reservoirs … the Southern California Coastal Water Research Project collaborated with leading researchers to select potentially viable methods and instruments for testing microplastics in drinking water and then subject them to real world testing at 22 laboratories from six countries … They are expected to be adopted by other governments and used worldwide …” #MicroPlastics #PlasticWaste #SingleUsePlastics #DrinkingWater @CaWaterBoards
