Application Note: Drinking Water Extraction using High-Capacity SPE Disks
6 February 2019

For more than 25 years now, the US has been testing for organic compounds in drinking water using US EPA Method 525. The most common version of this method, Method 525, is a diverse method with more than 100 compounds listed in a wide range of chemical groups such as pesticides, polychlorinated biphenyls, and polyaromatic hydrocarbons. Method 525 offers other changes to the method that may also be of use in making the method more rugged. Additional compounds are evaluated and may be added to the method as the regulatory list is amended every few years.
