Indoor Air Quality (IAQ) Investigations

The main purpose of the IAQ survey and on-site inspection is to locate and identify source pollutant(s) that resulted in poor indoor air quality. The IAQ assessment involves interviews with the building’s occupants for specific and nonspecific complaints that are generally associated with Sick Building Syndrome.  Symptoms such as headache, eye irritation, nose and throat irritation, and general fatigue are found to be associated with people when present in the building, and the symptoms subsided when these same people remained away from the building for some period. 

The elements of IAQ evaluations as conducted by ESI consists of real-time monitoring and laboratory analysis of air samples for the following common indoor air pollutants:

  • Volatile organic compounds (VOC)
  • Mold spores as a result of water intrusion and dampness
  • Formaldehyde concentrations in the air
  • Carbon Monoxide (CO) concentrations in the air
  • Carbon Dioxide concentrations for determination of HVAC fresh air intake
  • Dust Monitoring for airborne concentrations of lead particles
  • Air quality monitoring for Asbestos Fibers concentrations in ambient air

Envirosurvey, Inc. has conducted hundreds of various types of IAQ investigations in office buildings, residential dwellings, and industrial settings in the San Francisco Bay Area and has provided detailed reports of findings with conclusions and recommendations supported by laboratory results.
