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.
