Accurate laboratory results begin long before samples arrive at the laboratory. Proper field sampling techniques are essential for minimizing the potential for cross-contamination and ensuring data quality. Because PFAS compounds are found in many everyday consumer products, extra care should be taken during sample collection.
Advancing its commitment to supporting a comprehensive federal services program, Merit Laboratories has expanded its DoD ELAP accreditation to include Incremental Sampling Methodology (ISM) sample preparation.
Merit Laboratories is pleased to announce its participation in the 2026 International Conference on Remediation of Chlorinated and Recalcitrant Compounds (Battelle Chlorinated Conference), taking place May 31 – June 4, 2026, in Fort Worth, Texas. Recognized globally as one of the leading conferences for environmental remediation professionals, the event brings together scientists, engineers, consultants, regulators, and industry leaders to advance solutions for complex environmental challenges.
Incremental Sampling Methodology (ISM) is an increasingly accepted approach for characterizing soil contamination and reducing the uncertainty commonly associated with traditional discrete sampling methods. By collecting and combining multiple increments from a defined area, ISM is designed to provide a more representative estimate of mean contaminant concentrations within a designated decision unit.
Incremental Sampling Methodology (ISM) is increasingly used across the environmental industry to evaluate soil contaminants. Unlike traditional discrete sampling, ISM collects numerous soil increments that are combined, processed, and subsampled to produce more representative measurements of contaminant concentrations within a defined area.
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
In what surely will impact environmental regulatory programs across the United States, the EPA is actively prioritizing PFAS in the environment and has taken two recent actions to continue to address contamination. The EPA has issued a memo detailing an interim National Pollutant Discharge Elimination (NPDES) permitting strategy for PFAS.
To support PFAS investigations, monitoring, and scientific studies, Merit Laboratories has expanded its list of available PFAS compounds for environmental laboratory testing. Merit now provides analytical testing for 46 PFAS compounds by LC/MS/MS with isotopic dilution. Results were validated by the laboratory in an October 2020 Method Detection Limit (MDL) study.
The first-ever Great Lakes PFAS Summit has gone virtual. The event will bring together scientists, government officials, regulators, academic researchers, industry, and community organizations on all topics PFAS. The virtual summit is now scheduled for a five-day event, set for October 26th - 30th, 2020.
Significant levels of PFAS have been detected in the blood of Michigan residents in one state county. The results are summarized in the initial report just released by the Michigan Department of Health and Human Services (MDHHS) as part of the PFAS Exposure Study Assessment. This exposure assessment measured serum concentrations of 30 PFAS among a sample of residents in the northern part of Kent County area that previously had validated detectable PFAS levels in their private drinking water.
Merit Laboratories has become the first laboratory to be certified by the State of Michigan for PFAS testing in drinking water. Merit’s certification for PFAS testing, using EPA Method 537.1, is through the Michigan Department of Environment , Great Lakes & Energy (EGLE).
There are many locations in the state of Michigan where PFAS pollution has become widespread and where warnings been put in place such as; ’Do Not Eat’ fish advisories, and ‘No Swim Zones’. For example, residents living near the Wurtsmith Air Force Base, have health advisories in place warning people not to consume fish, deer and other wildlife in several areas, and avoid toxic surface water foam. The federal government, however, has yet to provide a universal, nationwide standard for PFAS.
The State of Michigan formally adopted a strict set of requirements regulating PFAS in drinking water. The Michigan EGLE announced the adoption of the new maximum contaminant levels (MCLs), which will go into effect on August 3, 2020. The establishment of enforceable MCLs for PFAS compounds will require compliance with the Safe Drinking Water Act (SDWA). Now they are adopted, the PFAS drinking water MCLs replace the current groundwater cleanup standard of 70 ppt for PFOA and PFOS.
