TriMatrix Supports U.S. EPA Detection and Quantitation Limit Study

Posted January 28 2010 in New Releases

TriMatrix recently completed their second project in support of the U.S. Environmental Protection Agency (EPA) on a Detection & Quantitation Limit Study. The goal of this project was to evaluate two alternative methods of determining detection limits as compared to the 40 CFR Part 139 MDL procedure currently in use. TriMatrix was one of only six laboratories nationwide involved in this study, and focused on the limits generated for the analysis of Semi-Volatile Organic Compounds using EPA Method 625. This was the second Detection & Quantitation Limit study TriMatrix has supported for the EPA.

TriMatrix also supported the initial pilot study for the U.S. EPA in 2006 on assessing detection and quantitation limit procedures in support of samples analyzed for Clean Water Act compliance. Our support to this pilot study included Metals by EPA 200.7, Cyanide by EPA 335.4, PCBs and Pesticides by 608, and Semi-Volatile Organics by EPA 625.

In 2005, the US EPA initiated a Federal Advisory Committee on Detection and Quantitation Approaches and Uses in Clean Water Act Programs (FACDQ). The purpose of this committee was to evaluate and recommend detection and quantitation procedures and uses of these procedures in Clean Water Act (CWA) programs. The committee included 21 members representing five groups of stakeholders: laboratories, industry, publicly owned treatment works or POTWs, States and Tribes, and environmental organizations.
