Indoor Air Quality

Indoor air quality (IAQ) has become an important occupational health and safety issue. In the past few decades, energy conservation measures have led to airtight building construction that can create problems with IAQ. Frequently the ventilation systems are set to minimize the amount of fresh air entering and circulating within the building. This restriction impacts indoor air by allowing a build-up of air contaminants within the building that are not properly removed.

W&M Environmental investigates, tests and recommends corrective action for IAQ problems such as mold, chemical contaminants such as formaldehyde, carbon monoxide, carbon dioxide, allergens, asbestos, lead and Building-Related Illness (BRI) or Sick Building Syndrome (SBS). IAQ problems typically arise from one or more of the following causes:

  • Indoor environment – inadequate temperature, humidity, lighting, excessive noise
  • Indoor air contaminants – chemicals, carbon dioxide build-up, dusts, molds or fungi, gases, vapors, odors
  • Insufficient outdoor air intake
