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 U.S. Environmental Protection Agency (EPA) formally announced the issuance of the next Toxic Substances Contract Act (TSCA) test order requiring PFAS testing. The new test order is being made under the National PFAS Testing Strategy. The EPA announced the action on January 4, 2023, which orders companies to conduct and submit testing for the PFAS substance HFPO. HFPO (CAS # 428-59-1), also known as trifluoro(trifluoromethyl)oxirane, is used in plastics manufacturing.
The U.S. Environmental Protection Agency (EPA) announced the release of Effluent Guidelines Program Plan 15 (Plan 15) to protect the nation’s waterways.

The conference will be held at Northern Michigan University’s Northern Center.
The Michigan EGLE recently added Harbor Island in Grand Haven to their list of PFAS sites. The Grand Haven site is a natural marshland at the mouth of the Grand River as it flows into Lake Michigan. The site was first used as a landing point for logging operations. During the 1950s and 1960s the site was used as a dump. The coal-fired J.B. Sims Generating Station began operating in the early 1960s by the Grand Haven Board of Light and Power (GHBLP). Coal ash wastes were disposed of in unlined lagoons and the adjacent wetlands. In the early 1980s, clay lined lagoons were constructed for coal ash management.
