Companies will now be prevented from starting or resuming the manufacture of over 300 PFAS compounds without a complete regulatory review and risk determination, based upon a new finalized rule announced by the U.S. EPA on January 8, 2024.
Environmental Testing, Merit Laboratories
Have you ever reviewed a laboratory report and felt overwhelmed by acronyms like MDL, RL, LOQ, or IDL? You’re not alone.

Another significant impact of wildfires is environmental contamination.
EPA, PFAS
The U.S. Environmental Protection Agency (EPA) continues to address the growing concerns over PFAS by adding nine new compounds to the Toxics Release Inventory. This move aims to improve transparency and provide better data on the presence and release of these persistent chemicals in the environment.
EPA 1633, PFAS, ASTM D8421, MUR
The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
