On September 3, 2019 ARI will be begin the transition to SW-846 method versions SW8270E, SW8260D, SW6010D, and SW6020B. All the specifics regarding the transition can be found in this post for the organic methods and this post for the inorganic methods. The method assigned to the samples on or after this day will depend on the accrediting agency for the project beginning with work done under WDOE. ORELAP and DoD related projects will follow later pending accreditation.
WDOE accreditation for EPA methods 625.1 (semi-volatile) and 624.1 (volatile) has already been approved. Please see the recently updated WDOE scope for the full list of accredited analytes.
Eventually ARI will no longer log analytical requests for the previous versions of those methods once all the replacement accreditations are issued. If you have questions regarding the changes and what it means to your project please contact ARI directly via your project manager or using the website contact form.
