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 Showcases Emerging PFAS Air Testing Capabilities at 2026 Chlorinated Conference
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.
Diverse Range of Analytical Soil Testing Using Incremental Sampling Methodology (ISM)
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.
Understanding Incremental Sampling Methodology (ISM) for Soil Contaminant Evaluation
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 Advances PFAS Testing with Participation in U.S. EPA Ultra-Short Chain Drinking Water Method Validation
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 Expands DoD ELAP PFAS Accreditation
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).
USDA Soil Permit Compliance: Protecting U.S. Ecosystems
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.
A Closer Look at the QA/QC Samples That Ensure Data Quality
When you receive your analytical report, you might notice several additional quality assurance and quality control (QA/QC) samples listed alongside your project data. These quality checks are not just routine - they are critical for validating data integrity, identifying potential interferences, and demonstrating defensibility in environmental decision-making. Below is a closer look at the most common QA/QC samples analyzed in environmental laboratories and what they can tell you about your data quality.

Soil Gas Sampling Made Easier with Merit’s Helium Shroud
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.
