When materials fail or PFAS concerns surface, pinpointing why is just as important as knowing what. At RJ Lee Group, we combine decades of forensic expertise, advanced microscopy, and certified PFAS testing to deliver answers that stand up in the lab, the courtroom, and the field.
At RJ Lee Group, we understand the critical role materials analysis plays in environmental investigations, remediation efforts, and industrial compliance. Our comprehensive suite of microscopy and spectroscopy techniques helps identify contamination sources, assess degradation mechanisms, and verify material integrity—supporting data-driven decisions in complex environmental scenarios. We employ a range of capabilities that are central to our analytical approach:
As regulatory scrutiny intensifies and litigation risks grow, RJ Lee Group stands at the forefront of PFAS testing and consulting. With decades of experience in industrial forensics and scientific analysis, our team delivers actionable insights and defensible data to help clients navigate the complex landscape of per- and polyfluoroalkyl substances (PFAS). Whether you're a manufacturer, legal professional, or environmental consultant, our accredited laboratory and expert staff provide the clarity and confidence you need to make informed decisions.
NELAP & A2LA Accredited for PFAS Testing - RJ Lee Group is accredited under NELAP and A2LA for PFAS testing, ensuring that all results meet the highest standards of compliance, defensibility, and scientific rigor.
Comprehensive Matrix Coverage - We investigate PFAS presence across a wide range of matrices, including soils, concrete, surface waters, biosolids, landfill leachate, and industrial waste streams. Our capabilities extend to both targeted and non-targeted analysis, using advanced instrumentation such as LC-MS/MS, LC-QTOF, and Total Organic Fluorine (TOF).
Litigation, Permitting & Remediation Support - Our scientific consulting team—led by experts like Michael Deible, Ph.D.—supports litigation, permitting, and remediation efforts with high-fidelity data collection, study design, and interpretation. We offer rapid turnaround times, custom sampling protocols, and expert witness services when needed.
Advanced Testing Methods - We utilize EPA Methods 537, 533, 1633, and ASTM 8421/8535, among others, to ensure comprehensive detection and quantification of PFAS compounds.
Consulting & Strategic Guidance - Beyond testing, RJ Lee Group provides strategic consulting on PFAS alternatives, supply chain evaluations, and regulatory response planning. Our team helps clients understand complex results, identify sources of contamination, and develop remediation strategies tailored to their operational needs.
With over 40 years of leadership in forensic materials science, RJ Lee Group has built a reputation for delivering clarity in complex investigations. Our casework spans diverse domains—from diagnosing concrete failures such as cracking, freeze/thaw damage, ASR, and scaling in bridges, marine, and industrial structures, to conducting metallurgical root-cause analyses on alloy breakdowns, coating degradation, and weld integrity.
We also lead in PFAS forensics, tracing contamination pathways, evaluating leaching from concrete, and supporting remediation programs with defensible data. Trusted by clients across infrastructure, energy, defense, manufacturing, and government sectors, our multidisciplinary expertise continues to drive impactful solutions where precision and reliability matter most.
