Since its initial publication in 2020, EPA Method 533 has become a leading approved analytical test method for the analysis of PFAS in drinking water. During this time, Merit Laboratories has analyzed thousands of samples utilizing EPA Method 533 for drinking water. In the publication of EPA Method 533 in 2020, Merit Laboratories was just a few national laboratories acknowledged in the approved method for PFAS testing in drinking water released by the U.S. EPA.
The Department of Defense (DoD) conducts sampling of drinking water off-base to ensure it identifies potential impacts of PFAS resulting from DoD activities. Off-base drinking water includes non-DoD drinking water systems and private wells located outside the installation boundary. The DoD provides final test results of off-base drinking water in accordance with Section 345 of the National Defense Authorization Act for Fiscal Year 2022.
The U.S. Environmental Protection Agency (EPA) formally announced the issuance of the next Toxic Substances Contract Act (TSCA) test order requiring PFAS testing.
