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.
The EPA recently announced changes in policy to new PFAS before it can enter the market. The current administration has made a commitment to focus on PFAS pollution and protect human health and the environment. Previously, some new PFAS were allowed to enter the market through low volume exemptions (LVEs).
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) released an update on the foam that often appears on Lakes and Streams. The EGLE routinely receives complaints about foam on rivers or lakes. This foam can be naturally occurring foam or foam caused by environmental pollution. Many things can be introduced into a lake or stream that may cause foam to form.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) recently began requiring wastewater treatment plants that land apply biosolids to have PFAS laboratory testing performed prior to the land application. The EGLE Water Resources Division started sending out notifications about this new program to affected parties this year. Merit Laboratories provides analytical laboratory testing for PFAS in biosolids sample matrices to support its wastewater clients meet their regulatory requirement obligations
On March 11, 2021, the EPA proposed the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) UCMR 5, which will require sample collection for 30 chemical contaminants, including PFAS. The testing will occur between 2023 and 2025 using analytical methods developed by EPA and consensus organizations.
The number of PFAS contaminated sites in the United States continues to expand at a rapid pace. According to the PFAS Contamination Site Tracker, managed by Northeastern University’s Social Science Environmental Health Institute (SSEHRI), there are now 1,244 sites with PFAS contamination and 1,114 water systems contaminated with PFAS.
The Michigan PFAS Action Response Team (MPART) has published a new sampling guidance document for leachate samples. MPART’s Leachate PFAS Sampling Guidance document covers the processes, decontamination procedures, and acceptable materials for sampling landfill leachate for per- and polyfluoroalkyl substances (PFAS).
The U.S. EPA is moving forward on the required next step in regulating PFAS in drinking water by issuing final regulatory determinations. After receiving more than 10,000 public comments, the EPA made the announcement on January 19, 2021, that they would follow the rulemaking processes required by the Safe Drinking Water Act (SDWA).
Updated cleanup standards were announced by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For groundwater used as drinking water, EGLE has included five additional PFAS compounds to Part 201, making the total number of PFAS regulated in groundwater to seven compounds. Effective December 21, 2020, the compounds PFNA, PFHxS, PFHxA, PFBS, and HFPO-DA
Merit Laboratories recognizes organizational leaders in PFAS science, which includes The Interstate Technology Regulatory Council (ITRC). The ITRC is a state-led coalition working to reduce barriers to the use of innovative air, water, waste, and remediation environmental technologies and processes.
Merit Laboratories is now certified for PFAS through the DoD Environmental Laboratory Accreditation Program (DoD ELAP). As a result, Merit Laboratories has expanded the list of analytical methods, compounds, and sample matrices for which it is accredited through the DoD ELAP, including the DoD’s PFAS method
