Indoor Air Quality Evaluations

Chemicals, Mold, Radon

Our company has extensive experience with investigations related to general and specific indoor air quality in non-industrial situations such as business offices, hospitals and schools.   Air sampling and analysis, and an evaluation of the ventilation system, commonly comprise our efforts in determining if an air quality problem does exist.


Our approach is to first listen to the complaints lodged by building occupants (through a manager), and then understand the physical aspects of the building, typically via facilities and maintenance personnel.  Knowing potential sources of air contaminants, we will try to tie the symptoms of the occupants to probable air contaminants.

With documentation of the levels of air contaminants in the building (usually compared to outside, ambient air), professional conclusions will be developed about the overall indoor air quality, and thus the “health” of the building. Information will be presented in a factual, understandable format, with clear recommendations of actions for the building managers or owners.

Common types of air sampling may include:

  • Aldehyde vapor scans (formaldehyde, acetaldehyde, acrolein, and propionaldehyde)
  • Volatile organic compound (VOC) scans
  • Acidic gas scans
  • Sulfur dioxide (SO2)
  • Oxides of nitrogen (NOX)
  • Carbon monoxide (CO)
  • Carbon dioxide (CO2)
  • Bioaerosols including mold, fungi and bacteria in air
  • Radon
