Merit Laboratories has expanded its air testing capabilities to now include the analysis of air samples for Polynuclear Aromatic Hydrocarbons (PAHs/PNAs) using TO-17. A representative list of TO-17 compounds analyzed includes ten compounds.
Soil, USDA
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.
Helium Shroud, Soil Gas
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.
NEMC
We’re excited to announce that Merit Laboratories will be participating in the conference, taking place August 4th - 7th, 2025, in St. Louis, Missouri. This year’s conference theme, “Building a Quality Culture as the Foundation for Reliable Data,” underscores the importance of quality assurance and continuous improvement in environmental monitoring and measurement.
Environmental Testing, Merit Laboratories
Have you ever reviewed a laboratory report and felt overwhelmed by acronyms like MDL, RL, LOQ, or IDL? You’re not alone. These terms are critical to understanding the sensitivity, precision, and reliability of laboratory results in environmental testing—but they can also be confusing, especially when used interchangeably or inconsistently across different labs or agencies.
