Indoor air quality (IAQ) issues impact the lives of people. Problems with poor air quality in buildings and homes can result in health concerns, liability issues, lost productivity, and decreased property values, whether the problem occurs in a residential, commercial or industrial environment. When IAQ issues arise, it is important to make sure that only a highly-qualified Trident Industrial Hygienist is called upon to investigate, mitigate and confirm that a problem has been properly resolved. Trident’s experts have experience in dealing with microbiological contamination (such as bacteria, mold and other fungi) and hazardous materials (such as asbestos, lead and many others).

Trident’s Industrial Hygienists, in cooperation with a Trident Civil Engineer in many cases, will:

  • Identify the contaminant and determine its cause and origin (C&O).
  • Design a remediation/abatement protocol according to recognized industry standards and guidelines.
  • Inspect contracting or remediation work to verify that the problem has been corrected and will not recur in the future.
