A History of Expertise and Innovation

RJ Lee Group has assessed environmental issues since the early 1980s when our Energy Technology Consultants (ETC) pioneered the recognition of specific air quality patterns. We developed a cutting-edge technique for identifying, measuring, and characterizing particles in the air using computer-controlled scanning electron microscopy (CCSEM).

RJ Lee Group has worked with clients in various industries, including the U.S. Environmental Protection Agency (EPA), to assess and provide solutions for environmental factors that could affect our health. Our services have grown over the years, from setting controls for unbound nanoparticles (UNP) to designing and building test chambers to simulate specific environmental conditions.

Today we offer our expertise for our clients’ environmental and compliance concerns and perform rigorous assessment and management of potential environmental risks.


Post-Disaster Assessment

Since our founding, our team of seasoned professionals has been at the forefront of post-disaster assessments, tackling the aftermath of catastrophes both man-made and natural. From the devastation of Hurricane Katrina to the tragic collapse of the World Trade Center, from train derailments to coal mine collapses, we've been there, providing expert guidance and support.

Our response team doesn't hesitate to dive into the heart of disaster zones, unraveling the cause of the event and assessing its impact. With a keen eye for detail and a wealth of experience, we provide comprehensive environmental health and safety recommendations, ensuring that recovery efforts are conducted in a safe and responsible manner.

When disaster strikes, trust RJ Lee Group to bring clarity and direction to even the most chaotic situations. We're your steadfast partners in recovery, helping you navigate the complexities of post-disaster scenarios and emerge stronger than before.

Team Involvement

Our team of experts takes charge in the aftermath of a disaster, providing comprehensive assessments and guidance for recovery. We start by conducting a thorough site inspection and evaluation, delving into both current and historical site information. Our scientists and engineers, with their combined expertise, work meticulously to determine the full extent of the disaster's impact. Initial sample testing is carried out to validate our methodology, and the results are compared against non-impacted samples for accuracy. Armed with these findings, we craft a comprehensive sampling plan tailored to address potential claims and remediation options.

But our involvement doesn't end there. We understand the importance of keeping everyone informed, so we work closely with the client and cooperate with local, state, and federal response agencies. We provide them with the necessary data to advise responders and the public on how to best mitigate any potential risks. Our team is committed to providing unwavering support throughout the entire post-disaster process.

We're your partners in recovery, ensuring that every step is taken with precision and care, guiding you towards a safe and resilient future.

Advanced Environmental Analysis with PTR-MS

In our pursuit of excellence in environmental assessment, RJ Lee Group utilizes Proton Transfer Reaction Mass Spectrometry (PTR-MS) technology. This innovative tool offers real-time, quantitative analysis of air quality, down to pptv-level precision. It's particularly effective in monitoring indoor air quality (IAQ), identifying potential legal or safety concerns, and ensuring compliance with industry standards and government regulations.

PTR-MS Technology Benefits:

  • No sample preparation required
  • Near real-time analysis with a response time of less than 100 ms
  • Instant quantification of air quality changes
  • Exceptionally low limit of detection for VOCs
  • Capability to discriminate between isomeric VOC compounds

PTR-MS Mobile Laboratory

Expanding our capabilities, RJ Lee Group has introduced the PTR-MS Mobile Laboratory. This innovative setup allows for on-site VOC measurements in various settings, from chemical plants to military facilities. It's equipped to handle both indoor and outdoor testing, providing valuable data for a range of applications, including urban air quality mapping, biomass monitoring, and agricultural assessments.


Environmental Stewardship in Military and Government Facilities

Our PTR-MS technology is particularly beneficial in military facilities, where historic chemical spills and other activities have created environmental concerns. This mobile laboratory system efficiently locates VOC emissions, helping to identify and address contamination sources.
