The Montrose network of testing professionals throughout the U.S. and Canada has decades of experience in a range of monitoring fields and applications. This enables us to excel in projects that range widely in scope and complexity, supporting the measurement or environmental testing lab requirements of the public sector, private industry, and governmental agencies. Our national network of accredited environmental quality testing labs provide clients with quick turnaround, best-in-class support, innovative science, regulatory expertise, and results our clients know they can count on.

Asking the right question is key, and leads to the generation of meaningful data that can be used with a high level of confidence for regulatory compliance or process improvement. We collaborate closely with clients to determine the best approach for each project, and manage the process from sample collection through final data submission. Our experts focus on generating high-quality, legally defensible data to address clients’ questions and resolve issues with credible, science-based solutions.

Employing practical methodology designed to economically resolve Indoor Air Quality problems, Montrose helps clients develop and conduct cost-effective, OSHA-compliant air or noise monitoring studies to assess exposure to airborne contaminants or determine the need for a hearing conservation program.

We have the expertise to properly implement the sophisticated isotope dilution techniques needed to get the most accurate and precise results where detection of highly-toxic compounds at Ultratrace levels is required. We apply these methods to analyze for both legacy PFAS, such as PFOS/ PFOA, and newer PFAS such as GenX. Our extensive compound list of 25 PFAS and our large sample capacity enable us to tailor our expertise to client- or program-specific criteria to provide the best analytical solution and generate the most reliable PFAS data available.
