Dear Shelia, This is a report based on site inspection and lab findings. I want to personally thank you for the time you have taken with me to help expedite this NORMI Certified LIMITED IAQ/Mold Inspection. I am satisfied that I now have enough information to draw some important conclusions and make some specific recommendations concerning the indoor air quality of this salon, and the protocols needed to restore a healthy environment. I appreciate you hiring a NORMITM Certified Indoor Air Quality and Mold Inspection specialist and remain ready to assist you with any of your indoor air quality concerns. Respectfully yours, Linda Eicher Certified Indoor Environmental Consultant

NORMI Certified IAQ/Mold Inspector Certified Indoor Air Quality Specialist NORMI Certified Biocide Applicator Member Green Professionals, USGBC Member Collaborative on Health and Environment NORMI Certified Trainer Director NORMIPro Environmental TASC Force Presentation Speaker USGBC Greenbuild Expo 2009General Information

Our recommendations are in accordance with standards established by NORMI (National Organization of Remediators and Mold Inspectors) and have proven to be successful in substantially improving indoor air quality throughout the United States. For more information on IAQ/Mold issues and their solutions, please reference the book entitled Mold-Free Construction by D. Douglas Hoffman, available at www.MoldFreeConstruction.com. You will find this book insightful and easyto-follow as you continue to improve the environment indoors. This IAQ/Mold Inspection references the following property: 6935 Old Lawyers Rd. Charlotte, NC 28227 This property was inspected on August 31, 2010.

This was an inspection based on concerns about air quality issues that may be affecting some of the past technicians, especially two who worked in the back room. Both of them had complained of increased allergy symptoms while working there that they did not have to the same degree at home or elsewhere. Both were also smokers.

Property HistoryThis salon used to be a home, built in 1934, about 1800 sq. ft., one level over a crawlspace/ basement. The back room was gutted and redone in recent years. The kitchen had a flood from a sink pipe which is still being remedied and insurance is involved in replacing the flooring. The flood was AFTER the other issues complained about so was not likely to be affecting their air quality.

Visual InspectionExterior: The exterior of the house shows some aging and lack of rain gutters/downspouts. This could easily create moisture issues in the foundation, crawlspace and basement, promoting fungal growth. The basement/crawlspace has some visible fungal growth and has a strong odor of mold. Interior: The interior of the salon has typical chemical odors from processing and operations. The back room has both a central HVAC supply in the ceiling and a wall unit that is used when the room is heating up from hair drying. There is a musty odor in some areas, especially ones closed up from air circulation like the closets. The ceiling in one room is swelling but probably due to poor suspension of ceiling tiles. There was no moisture detected.

Diagnostic TestingMoisture Meter Readings Moisture Meter readings can add to your understanding of the indoor environment. The moisture meter we use is a Wagner BI-2200 which is a non-penetrating meter designed to recognize moisture content of construction materials that have been tested. The general rule of thumb in our industry is that moisture content in construction materials in excess of 17% MAY indicate a moisture problem. Since we are often unable to test in wall cavities, attics or other non-visible locations, we can only draw limited conclusions about the moisture of any area tested. These conclusions, however, are included in our over-all assessment and evaluation of the IAQ/Mold Profile in your environment. There were no high levels of moisture found in any of the floors, walls or ceilings tested throughout the salon except on the floors of the kitchen and extending out somewhat into the main salon room. These floors are vinyl over vinyl and water could be trapped in layers and is probably also saturating wood subfloor. Temperature/Relative Humidity The temperature in the salon was 76F and the relative humidity was 45% which is normal and not conducive to fungal growth. Lab Analysis Attached find copies of laboratory results from sampling taken by me on your indoor air quality. There are five different types of testing we could have performed and it is our responsibility to use our experience and expertise to assess which testing procedures will give us the best IAQ/Mold Profile of

your indoor environment. Should additional testing be required, we may select one or more of these methods to enhance our understanding of your environment so we will have an objective overview of your indoor air quality. The five methods from which we choose are: 1) Air o Cell Samplingin this process we collect particulate from the air to get a comparison count between the indoor air and the outdoor air. This type of sampling does not indicate viability. 2) Air - Impaction Samplingthis process uses gravity or pressure to plate a Petri dish with airborne particulate and then incubate for the laboratory to identify. This method only represents a small sample of the entire indoor air environment. 3) EnviroSWAB Samplingthis is an effective way of collecting dust which includes viable mold spores, plate them to a Petri dish, and have the laboratory identify and count the number of live colony forming units (cfu). This method recognizes only the viable mold that has settled out in the location where it has been collected. 4) EnviroTAPE Samplingwhere visible mold is present, this tape lift method allows the laboratory to identify and count the number of dead or live colony forming units (cfu). This method does not recognize viability of mold growth only the presence of mold. 5) Bulk Samplingoccasionally we determine that specific construction materials or other items require laboratory testing to identify and count the number of either dead or live colony forming units. (cfu) This method does not recognize viability of mold growth only the presence of mold. We are not attempting to make you a Certified IAQ/Mold Inspector but want you to understand the different methods of collection so you will better understand why we choose the following methods. I utilized Swab Sampling on the visible fungal growth in crawlspace and on the supply the HVAC system in the back room as well as the coils on the wall unit AC so we could identify and quantify both the visible growth and possible invisible contamination. An air sample was also taken in the back room.

Inspection SummaryUpon review of each aspect of the inspection, as a CMI, I respectfully submit this to you: The air sample taken in the back room showed above normal levels of contaminants in the limited range, primarily Aspergillus/Penicillium and Cladsporium. The swab sample taken on the HVAC supply vent in the back room showed above normal ranges of several species of molds, primarily Cladosporium and Penicillium. The swab sample taken on the coils of the window AC unit in the back room showed above normal ranges of Cladosporium and some bacteria. The swab sample taken on the joist in the basement showed above normal ranges of Cladosporium along with some Penicillium and other molds. There are several possible conclusions to be drawn from this inspection: The combination of low but constant exposure to molds in the salon, along with chemical fumes and the fact that both workers smoke can cause some exaggerated allergy symptoms in some people.

Molds seem to enhance respiratory irritation when combined with effects of smoking as many studies have shown. The air quality in the salon is not optimally healthy for long-term exposures. The age of the structure makes it less air-tight between the basement and interior so many contaminants can enter through various cracks and gaps. Older ducting can easily become unsealed too and allow contaminants to get into the system from the basement/crawlspace air. The musty odors in the salon indicate active mold growth somewhere in the structure, most likely underneath where observed and sampled.

Recommendations:All recommended protocols are in accordance with IICRC s520 standards and guidelines for remediation and/or sanitization of mold, and NORMI protocols for sanitization of contaminants and moisture control. The air ducts could be cleaned with a safe sanitization process, as well as the coils and plenum to reduce contaminants. The coils on the wall unit AC can also be cleaned effectively with a safe antimicrobial solution. Make sure all wet flooring is dried completely and/or replaced that flooded from the pipe leak in the kitchen. Have a basement/crawlspace professional look at those areas and recommend cost-effective cleaning/drying solutions. I recommend Dry-Pro at 704-523-9111. I recommend placing an activTek InDuct 2000 in the central HVAC system on the supply plenum to provide active purification through the ducting and continuous cleaning capabilities throughout all the spaces of the salon. Both air and surface contaminants such as molds, germs, odors, chemical fumes and fine airborne dust can be significantly reduced with this system. It is a natural process replicating the way outdoor air scrubbing elements work. It will help protect the breathing spaces from molds, odors and salon chemicals as well as help control the fine particle airborne dust.
