Over the years, our personnel have developed an expertise in performing indoor air quality investigations. Initial baseline testing typically involves collecting temperature, humidity, carbon dioxide, and carbon monoxide levels, screening for microbial growth, and inspecting the ventilation system. Detailed sampling can be performed for total volatile organic carbons at part per billion levels, microbial volatile organic carbons, fungal and bacterial identification, endotoxins, and determination of dust mite, cockroach, and other allergens.
