Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group provides expert and objective post disaster assessments, encouraging stability and providing data for remediation. Our response team doesn’t hesitate to determine the nature of the the impact of a disaster, and have years of experience dealing with chaotic situations immediately following catastrophes both man-made and naturally occurring. Whether dealing with the aftermath of Hurricane Katrina or the World Trade Center towers collapse, a train derailment or coal mine disaster, we provide the sampling and analytical support needed for accurate post disaster assessment, including investigations for occupational health and safety and/or environmental health and safety, as well as efforts of remediation.
Team Involvement
Our post disaster assessments begin with site inspection and evaluation. After reviewing current and historic site information, our team of scientists and engineers work to determine the extent of the impact. Initial sample testing is performed to validate methodology and results compared to non-impacted samples. Using these results, we propose a sampling plan designed to address potential claims and remediation options. But our involvement doesn’t end there. To ensure that everyone affected by the circumstances is aware of potential risk, we work with the client and cooperate with local, state and federal response agencies to provide needed data so that the agencies can advise responders and the public in how best to deal with any potential risk.

Clearing the Air

Physical changes in structures impact people and our environment, whether they are intentional as in a building renovation or bridge demolition, or accidental as in a structural failure or a natural disaster. RJ Lee Group has extensive experience in designing and implementing dispersion and receptor modeling plans, conducting air monitoring to measure particulate matter, asbestos, dust, vapors, metals and crystalline silica, PCBs, PNAs and dioxins, and conducting environmental site assessments. Arenas in which our environmental post disaster assessment expertise is used include:

  • Physical and environmental damage assessment
    • Flood, fire, earthquake, explosion, or other catastrophic events
  • Emergency response
    • Deployable field team and mobile laboratory
    • Coordination, oversight, and logistics
    • On-site, real-time data collection
  • Environmental & materials sampling and analysis
    • Air, soil, water, and wastes
    • Source contamination apportionment
    • Particulate characterization
    • Construction materials (concrete, composites, aggregates, steel, fibers)
  • Remediation assessment, planning, and monitoring
    • Property, plant, building, and equipment assets
    • Waste stream profiling
  • Industrial hygiene monitoring
  • Root cause analysis
From Beginning to End

We provide expertise that addresses each post-disaster situation individually. The support that we bring to the table can be unilateral or as comprehensive as our client requires. Our experts partner with world-class organizations to provide seamless support in other areas such as risk assessment, structural assessment and comprehensive remediation strategies.
