Merit Laboratories is proud to have been a participating laboratory in a multi-laboratory validation study to support a new ultra-short chain PFAS drinking water method under development by the U.S. Environmental Protection Agency. This study represents an important step toward standardizing the measurement of ultra-short chain PFAS in drinking water and other aqueous environmental matrices.
Merit Laboratories is proud to announce an expansion of its PFAS accreditation through the Department of Defense Environmental Laboratory Accreditation Program (DoD ELAP), reinforcing our commitment to delivering high-quality, compliant PFAS data for defense and federal projects. Merit Laboratories’ DoD ELAP scope now includes the following compounds analyzed by EPA Method 1633 (LC/MS/MS).
Soil can be a vector for harmful bacteria, plant viruses, fungi, nematodes, and other biological propagules. To safeguard U.S. agriculture and natural resources, the United States Department of Agriculture (USDA) strictly regulates the movement of soil, both from foreign sources and from domestic areas under federal quarantine.
We are excited to congratulate our outstanding clients for being recognized among the Top 200 Environmental Firms of 2025, as ranked by Engineering News-Record (ENR). This well-earned recognition reflects your dedication to innovation, quality, and excellence across the environmental industry.
Collecting high-quality soil gas samples in the field for TO-15 analysis is essential for generating reliable data. Yet in the field, the process can be time-consuming and prone to error. With our clients’ sampling challenges in mind, Merit Laboratories designed a helium shroud that makes soil gas sampling more efficient, accurate, and reproducible — without the need for tools or field calibration.

We’re excited to announce that Merit Laboratories will be participating in the conference, taking place August 4th - 7th, 2025, in St. Louis, Missouri. This year’s conference theme, “Building a Quality Culture as the Foundation for Reliable Data,” underscores the importance of quality assurance and continuous improvement in environmental monitoring and measurement.
To all of our friends and partners in California impacted by the devastating wildfires, Merit Laboratories is here to support you. When wildfires ravage communities, natural landscape, and places we call home, the impact is major. Lives are interrupted while homes, schools, and businesses are destroyed. Another significant impact of wildfires is environmental contamination.
We are thrilled to extend congratulations to our incredible clients for being recognized as top-ranked companies in the 2024 ENR Top 200 Environmental Firms. This achievement is a testament to your hard work, innovation, and commitment to excellence. The ENR Top 200 Environmental Firms, released on October 14, 2024, includes 32 companies that are clients of Merit Laboratories.
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.
