New contaminants. Evolving regulations. Tighter project timelines. The demands placed on environmental testing have never been greater, and at RJ Lee Group, we've been responding.
We've made significant investments in new analytical methods and technologies, expanding what we can test for, how quickly we can deliver results, and how comprehensively we can serve as a single-source laboratory partner. Here's what that looks like in practice.
A Growing Analytical Footprint
Our expanded capabilities now cover the full range of environmental matrices and contaminant classes required for your projects:
PFAS Analysis
• EPA Methods 533, 537.1 & 1633
• ASTM D8421 (previously 7979)
• ASTM D8535 (previously 7968)
• ASTM WK88581
Metals & Inorganics
- ICP-AES (SW-846 6010, EPA 200.7)
- Mercury (EPA 245.1)
& Industrial Hygiene
- Elements (NIOSH 7303)
- PAHs in Air (TO-13A)
- Purgeable Organics / VOCs
- Gasoline Range Organics & BTEX
- Naphthas & Industrial Solvents
- Aldehydes
- Welding Fumes
Water & Wastewater Chemistry
- Total Dissolved Solids (TDS)
- Total Suspended Solids (TSS)
- Nitrate/Nitrite
- Phosphorus
- Ammonia
- TCLP Sample Preparation
Mobile Testing Services
- PTR-TOF-MS
- AIM-TOF-MS (CI)
- Gas-Phase FTIR
Built on a Foundation of Nationally Recognized Expertise
These additions don't stand alone. They add to the already deep bench of scientific capability that RJ Lee Group has built over decades, including nationally recognized work in PFAS, vapor intrusion, air toxics, stack emissions, ambient air monitoring, industrial hygiene, materials characterization, forensic analytical services, microplastics, and advanced mass spectrometry.
The result is a laboratory that can follow a project wherever it leads, across contaminant types, sample matrices, and regulatory frameworks, without handing you off to someone else.
One Partner. One Standard of Science.
Our goal hasn't changed: to deliver scientifically rigorous data, exceptional service, and rapid turnaround from a team you can trust.
If your organization is navigating complex environmental, industrial, or regulatory challenges, we'd welcome the opportunity to talk through how RJ Lee Group can support your work.
