When EPA sets a drinking water monitoring requirement for a contaminant, the Agency also establishes in the regulations at least one reference analytical method for analysis of the contaminant. Section 1401(1) of the Safe Drinking Water Act (SDWA), as amended in 1996, authorizes EPA to approve “equally effective” testing procedures through the publication of a notice in the Federal Register. This provision within SDWA establishes the basis for EPA’s drinking water expedited method approval process. EPA has used the expedited approval process since 2008 to approve over 100 alternate test methods, including methods that offer ‘greener’ alternatives to older methods that use toxic materials and/or generate hazardous waste.

The presentation will describe methods that have been approved in the most recent expedited Federal Register notice. In addition, the presentation will convey some of the current collaborative efforts on methods within the Office of Groundwater and Drinking Water’s Technical Support Center. This includes working with stakeholders to update and revise several of EPA’s 900-series radiochemistry methods and with vendors to evaluate new method technologies for drinking water compliance monitoring.
