US EPA prioritizing two VOCs used in Purge and Trap analysis for risk evaluation

Posted by Amy Nutter on Mon, Feb 05, 2024 @ 08:57 AM

Late last year, the United States Environmental Protection Agency (EPA) announced it will be prioritizing five toxic chemicals for risk evaluation under the Toxic Substances Control Act. During this process, if the EPA designates these chemicals as High Priority Substances, they will undergo an extensive comprehensive study. These studies will be crucial to helping protect people from toxic exposure.
