Environmental Health & Safety

We Are Environmental Experts

RJ Lee Group has assessed environmental issues for more than 35 years. In the early 1980s, as Energy Technology Consultants (ETC), our scientists were pioneers in recognizing specific air quality patterns, and eventually developed a technique for identifying, quantifying, and characterizing air particulate using computer-controlled scanning electron microscopy (CCSEM). Through the years, our scientists have worked with government and industry to assess and help control factors that can potentially affect our health, from setting controls for unbound nanoparticles (UNP) to designing and constructing test chambers for simulation of controlled environments. Our range of services has expanded over the years, and today we offer expertise that targets not only areas of environmental concern and compliance issues, but more in-depth projects for the assessment and control of those environmental factors that can potentially affect our health.

Clean Air, Clean Workplace

Our Industrial Hygiene experts observe, consult, design, analyze, and recommend. Our involvement begins with consultation, site inspection and evaluation. After elicit the information needed to correctly assess the situation, we respond to our clients’ needs with a monitoring and sampling plan designed to specifically address their requirements. Samples are analyzed, and our experts evaluate the results and recommend a plan of corrective action. We also identify gaps in existing programs and recommend updates and modifications to policies and procedures or design a completely new plan of action.

At RJLG, we have extensive experience in designing and implementing air sampling and monitoring plans, performing environmental site assessments, and dispersion and receptor modeling plans for heavy industry. Our scientists also perform stack testing to determine trace contaminants in the air, and source apportionment plans to determine the contributions of various pollution sources to a location of interest.

Beyond Air Monitoring

We observe manufacturing processes to uncover any environmental or occupational issues and recommend changes to reduce potential exposure and contamination. Our expertise ranges from the regulatory demands of hospital pharmacy and clean room environments, to the characterization of aggregates and nuisance dust in the construction industry, to the monitoring of air in coal mines and examination of flyash from coal-burning plants. Our experts contribute to a safe and clean working environment by providing testing, prevention and control techniques such as:

• OSHA, MSHA and EPA-mandated analytical methods for clients who routinely conduct compliance monitoring for asbestos contamination, crystalline silica testing, metals and vapors
• Routine monitoring and analysis of air samples at each step in a process to establish a benchmark for acceptable clean air levels
• Nanoparticle assessments and characterization
  Process monitoring to proactively identify, track and resolve consistency and cleanliness issues
• Testing to provide information for MSDS or product warning labels
• Simulation chamber studies in controlled environment to predict potential occupational exposure
• Receptor and source modeling plans for industries such as energy and mining
• Materials characterization during any step in the product life cycle
• Indoor environmental quality investigations in hospitals, pharmaceutical and microelectronic manufacturing areas
• Identification of underground environmental problems such as dusts, temperature, and humidity
• Assessment of natural and mechanical ventilation systems
