Air Sampling
At Tri State Restorations we offer air sampling by a certified inspector, trained in appropriate sampling methodology.
Air samples are collected via a Micro – 5 bio – aerosol sampler or Air – o- Cell Cassette. This type of sampler imparts viable spores on potato dextrose agar Petri dishes placed in the apparatus at the rate of 5-15 cubic liters of air per minute. After a five or ten minute sampling period, the impacted fungi Petri dishes are sealed and void of all ambient light. The impacted fungi Petri dishes are incubated at a temperature suitable for fungal growth. The most accurate mold identification is possible within a short time of live culturing for the mold cultures to reach their maximum identification growth. After a short time of incubation, the fungi samples are removed and if possible via visual identification under a microscope, specifically identified down to the genus and species. Results are provided in colony forming units per cubic meter of air.
Air testing should be performed if there is evidence from a visual inspection that the ventilation system may be contaminated. The purpose of such testing is to assess the extent of contamination throughout the building. Sampling should be conducted while the ventilation system(s) are operating.
Air monitoring should also be performed if the presence of mold is suspected in a particular area of the structure (e.g. a microbial volatile is detected) but cannot be identified through a visual inspection or bulk sampling. The purpose of such air monitoring is to determine the location and or extent of mold contamination.
If the building inhabitants are suffering from health problems, which are or may be associated with fungal exposure, air and mold testing will need to take place. Air monitoring should be performed for comparative purposes and at a location representative of outdoor air.
The outdoor control test is very helpful in evaluating whether there is an internally generated problem. Such a mold may exist if indoor mold tests report mold levels are either (a) Higher than the outdoor test. (b) Present indoors but absent from the outdoor control air test. The samples are sealed, labeled and delivered to the laboratory within 24 hours.
At Tri State Restorations we believe in giving our clients choices that fit their needs. We know time is of the essence when it comes to your family’s health. In most cases we can offer next day business interpreted lab results.
