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 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 has expanded the list of analytical methods, compounds, and sample matrices for which it is accredited through the DoD Environmental Laboratory Accreditation Program (DoD ELAP). Through this expansion, the DoD officially revised Merit Laboratories' DoD ELAP testing certification to also now include EPA Method TO-15 for the analysis of air samples. Merit is also analyzed for a comprehensive list of analytical methods for aqueous and solid sample matrices.
The U.S. Department of Defense is actively performing assessments of PFAS usage and potential releases at more than 650 military installations throughout the country. The list of installations includes sites in all 50 states, the District of Columbia, Guam, Marshall Islands, Midway Islands, Puerto Rico, and the U.S. Virgin Islands. The military installations being assessed cover a diverse range of DoD facilities
