In a recent article published on the EMLAB P&K bacterial and mold lab testing website, the reasons why Ozone remediation in properties is flawed were outlined by Dr. Harriet Burge. The following is a list of fundamental reasons as to why the ozone medium isn't recommended for mold resolution:
1. No single peer-reviewed, academic study supports the notion of using ozone technology for mold remediation.
2. Although higher levels of ozone have been shown to reduce levels of fungi, these concentrations also have the ability to damage building contents.
3. Ozoning has been shown to reduce fungi levels on hard surfaces, and to be much less effective on porous surfaces. This is an issue since a lot of mold issues are present on porous materials, such as drywall.
4. The use of the ozone technique can create a separate air quality issue in the property and potentially be hazardous to occupants and workers.

Aspergillus type mold (species not specified) was recently discovered at a children's hospital in Seattle.
The mold was discovered in the ventilation system, which spread to 14 rooms. With exposure to Aspergillus, symptoms resulting from certain species of this type of mold are referred to as Aspergillosis, which is a resulting infection.
Mold issues within the HVAC ventilation system command more attention since spores can be dispersed throughout a property within a system which should be enhancing the air quality, but is rather compromising the air quality in a property. Testing for airborne mold spores in each room in this event can help determine where the spores are spreading, as well as consulting for a mold inspection and an HVAC inspection by a licensed HVAC technician.

Facts taken from U.S. Department of Housing and Urban Development, Healthy Homes Issues: Mold. Version 3
The California Department of Public Health (CDPH) categorizes mold as being under a substandard living condition. As stated by the CDPH,
"CDPH has concluded that the presence of water damage, dampness, visible mold, or mold odor in schools, workplaces, residences, and other indoor environments is unhealthy."
Therefore, once mold has been documented and mold is registered via an inspection and relevant testing, it is paramount that remediation and restoration is performed in the pertinent property to ensure it is restored to an appropriate standard. The CDPH further added that,
"Beginning Jan 1, 2016, the presence of visible mold will be added to the list of conditions in the California Housing Code, already including dampness of habitable rooms, that make housing substandard (Cal. Health & Safety Code §17920.3)".
If you believe there is potentially mold in your property, or residual or active moisture from a current leak or previous leak, it is recommended reaching out to a local mold inspector, environmental health inspector or industrial hygienist to assess the area(s) of concern.
Often, clients will hear water restoration and mold remediation companies refer to "IICRC standards" or that their methods are "in accordance with IICRC". Understandably, the majority of people outside of this industry are baffled by the IICRC acronym and the implications behind it.
The IICRC, which is an acroynym for the Institute of Inspection, Cleaning and Restoration Certification, has certain guidelines that are followed by mold and water restoration remediators. Updated editions are often released that keep industry professionals apprised of the most pragmatic and efficient remediation tools and exercises.
In the 3rd edition, the s500 Standard and Reference Guide for Professional Water Damage Restoration, there are references to the appropriate amount of drying equipment to use on a property, relative to the damage experienced. Various algorithms are used to calculate the appropriate amounts, which are delineated in the following classes:
Being familiar with this class system, prior to having work performed in your property, can help you understand what level of work is actually required if you experience a water damage restoration issue.
The appropriate drying method would be determined based off of an inspection. According to industry experts, the most common 'class' documented is Class 2. The following levels of drying are associated with each class:
This is a summation of the general drying techniques after an area has experienced water damage. It is recommended that, if one has experienced a great amount of water damage, they consult with an IICRC certified professional to have restoration work completed in the property.
