  • Mold, dust and pollen sampling, data interpretation
  • Chemical and radiation surveys by survey meters or laboratory analysis
  • Ventilation surveys
  • Tenant or employee complaint investigations



Molds are naturally occurring in the environment. Molds reproduce by dispersion of microscopic spores in the indoor and outdoor air. Mold may begin growing in the indoor environment when spores land on surfaces which are wet. Molds favor cellulose as a food source. Many modern building materials contain cellulose, including drywall and ceiling tile. Carpets can also act as a repository for mold and bacteria. There is no practical way to eliminate all molds or mold spores in the indoor environment; however, mold growth can be controlled by controlling moisture. Other biological particles may be present in the indoor air, including bacteria and pollen. Collectively, these particles are referred to as bioaerosols.


Alliance can provide testing of indoor and outdoor air, HVAC components and building materials for bioaerosols. There are many other components of good indoor air quality. Occupant comfort is a major consideration. Combustion sources should also be considered. Chemicals and ozone may also cause indoor air quality problems. Humidity may either enhance or degrade the quality of indoor air. Most (greater than 80 percent) indoor air quality problems are caused by inadequate or improper ventilation. Alliance monitors for temperature, relative humidity, carbon dioxide (CO2) and carbon monoxide (CO) to insure that common sources of IAQ problems are evaluated.


More About IEQ:

We create reports after Indoor Air Testing is complete.  The report can speak to several issues.  First, it can call your attention to existing ambient conditions in the building.  Secondly, the report speaks to issues of bioaerosols and microbials present in the building.  Lastly, we provide recommendations for remedial actions sometimes, which should be implemented in order to alleviate any conditions that are potential health concerns and provide an operating environment free of potential air quality contaminants.

In our examination of the operating parameters of the School, we follow several written protocols for the analysis of air quality.  Our tests are all founded on solid guidelines for the quality of indoor air which are taken from several technical resources.  In addition to those supporting documents, we have added our field expertise in conducting numerous examinations of indoor air quality and high-quality construction work practices.

The report should be examined in its entirety to direct any recommended remediation and not be separated into an out-of-context interpretation.  It is our intent to provide historical data, current operating conditions and, if necessary, to suggest corrective action plans.  We anticipate that our information will be shared in its entirety with all parties.  If there are any questions or other concerns after reviewing the report, please contact our office.
