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.
Moving Michigan forward on PFAS drinking water regulations, the Science Advisory Workgroup recently provided its health-based values to the Michigan PFAS Action Response Team (MPART). These PFAS health-based values will be used by the State of Michigan to develop regulatory drinking water standards.
Because soil can potentially contain harmful bacteria, plant viruses, fungi, nematodes, and other propagules, the United States Department of Agriculture (USDA) regulates the importation of soil for both domestic regulated and foreign soil. These regulations are put in place to protect agriculture and natural resources from the introduction of destructive plant and animal diseases.
The U.S. Environmental Protection Agency (EPA) finally validated EPA SW-846 Method 8327 for the analysis of PFAS using LC/MS/MS instrumentation for non-potable water. Sample matrices for EPA 8327 include surface water, groundwater water, and wastewater. The method evaluated 24 PFAS compounds.
The congressional bill recently introduced that would require the U.S. Geologic Survey to monitor for PFAS received a hearing on June 13th. The PFAS Detection Act, introduced in March, authorizes the U.S. Geologic Survey and the U.S. EPA to coordinate and develop PFAS testing standards. The bill requires that the USGS monitor for PFAS nationwide in water through a five-year, $45-million program.
Soil gas sampling is easier with Merit Laboratories’ helium shroud. Working closely with our client’s field sample collection needs in mind, Merit developed a helium shroud that makes soil gas sampling more efficient, accurate, and reproducible. And don't worry about tools or calibration in the field. Merit’s helium shroud requires no tools or field calibration. The helium shroud's quick-connect ports are proven time savers in the field. We make it easier.
Residents can now track the locations of PFAS sites in Michigan, which continues to grow. According to the most recent update to the PFAS Map Tracker from the Michigan EGLE (formerly MDEQ), the number of confirmed PFAS contaminated sites has grown to 52. The PFAS site map shows sites spread across Michigan.
The MDEQ has been directed by the governor to begin the process of creating PFAS drinking water standards. The MDEQ will file a Request for Rulemaking to establish maximum contaminant levels (MCLs). As part of the governor’s direction, the Michigan PFAS Action Response Team (MPART) will form a science advisory workgroup to review health-based drinking water standards to support the rulemaking process and make recommendations by July 1.
