New PFAS testing option for initial monitoring
Starting January 16, 2025, EPA approved EPA Method 537.1, Version 1.0 as an alternative test for initial monitoring of selected PFAS (PFBS, PFHxS, PFNA, PFOS, PFOA, and HFPO-DA/GenX). EPA lists this method for initial PFAS monitoring under 40 CFR 141.901(b)(1) and notes the method is approved to support initial PFAS monitoring until April 26, 2027.
Automated chlorine test approved for routine monitoring
Effective January 16, 2025, EPA approved the e-sens Automated Micro Chlorine Detection (AMCD) Method as an alternative for measuring free and total chlorine in drinking water. EPA determined the e-sens AMCD Method is equally effective relative to the approved Standard Methods (4500-Cl series), allowing public water systems and labs to use this vendor method for compliance monitoring.

The U.S. government just added 16 companies—14 in China and 2 in Singapore—to a special watchlist called the Entity List because they’re seen as risks to national security or U.S. foreign policy. Starting January 16, 2025, exporting certain products to these companies will need extra licenses, making business with them trickier and potentially more costly. This move aims to keep sensitive tech and goods out of the wrong hands while sending a clear message.
