Lists of Approved Analytical Methods for Drinking Water

EPA has recently posted updated lists of the approved analytical methods for testing drinking water on their analytical methods web page.  There are updated tables for inorganics, organics, radionulcides, disinfection byproducts and secondary contaminants.   The site also includes the tables of methods for other rules such as Ground Water Rule, Total Coliform Rule, and surface water treatment rules.  Also included on the webpage is a document that covers the sources of all the approved methods and information on how to get copies of the methods.
