PRIME Engineering & Environmental Building Services EngineeringEnvironmental.com 2801 Ocean Drive, Suite 101, Vero Beach, FL 32963 (772) 410-3752 February, 2015 To: City of Fort Pierce Fort Pierce Redevelopment Re: 2802 Ave. I, Ft. Pierce, FL 34950 - Mold inspection and testing At the request of Fort Pierce Redevelopment, I inspected the subject property relative to mold and related issues on February 20 th and collected three bio-air samples; two from the inside the house and one from the exterior. The air samples were collected using Air-O-Cell cartridges with calibrated biopumps at 15 liters of air per minute for 10 minutes. (150 liter sample) This type of testing captures fungal spores and can indicate sporulation and spore concentrations, along with the types of mold present. The cartridges were sent to a certified laboratory for fungal spore analysis accompanied by a signed chain of custody form. The complete laboratory report is attached to this document. The findings and recommendations from the inspection and air testing are provide below. Visual assessment: 1. A new roof is needed. The existing roof is not appropriate nor does it comply with residential building code requirements. A proper and water tight roof is imperative to keep moisture out of the structure and to prevent the growth and spread of mold. 2. Several sections of the ceilings inside the house need to be replaced. Some are water stained or damaged, and some have fallen down leaving the attic visible. This allow dirty, hot, and humid air to flow into the living space and will contribute to the growth and spread of mold. The ceilings must be repaired to provide separation of the living spaces from the attic. Page 1 of 4
3. Inside the house on and adjacent to the water stained and damaged ceiling areas, there is evidence of mold growth in several locations. All such areas of the ceiling drywall need to be removed and replaced with new material. Removal or remediation of water damaged material and mold should be conducted by a licensed Florida mold remediator in accordance with ANSI/IICRC S300, S500, and S520. 4. The air filter inside the air hander needs to be replaced and we recommend the cooling coil for professional cleaning by a licensed heating and cooling contractor after items 1-3 above are completed. 5. The inside of the house has many stored items and organic materials that can more readily allow mold to grow and spread. I recommend thorough cleaning of all interior surfaces and finishes along with cleaning of personal and stored items. Laboratory test results: 1. The indoor air samples show the fungal ecology (concentration & types of mold present) within the living space is acceptable. However, the conditions noted above need swift action to prevent mold from becoming a larger problem for the indoor environment other than the couple locations of visible mold growth noted above. Moisture assessment: Moisture analysis was conducted in limited areas inside the property using an Infrared (IR) camera and a SurveyMaster moisture meter. The moisture measurements should not be interpreted as exact moisture content measurements of a material but should be interpreted as the relative moisture reading of the material at the time of measurement. PRIME Engineering & Environmental Building Services uses the following benchmarks* for the percent (%) Wood Moisture Equivalency as an interpretive guide to the conditions measured in the building materials tested. > 20.0% Relative moisture present in the material tested that provides favorable conditions for microbial growth Page 2 of 4
15.0-20.0% Caution - relative moisture present (other factors such as humidity, water damage must be assessed for interpretation of the material tested) < 15.0% Recommended levels to prevent the opportunity for microbial growth No active moisture was detected (readings > 15%) at the time of our visit. Photo Gallery: Notes and Limitations: The observations made in this report are based on a non-invasive assessment of the indoor space at the time of our visit. Hidden areas of mold growth may exist and areas of damage not related to the issue/claim may also exist. We attempt to identify moisture leaks and the presence of moisture, but we do not guarantee locating or finding any moisture activity or leaks due to many factors. Specialized testing or destructive analysis and removal of wall or floor finishes may also be appropriate, but such is not included with our service. Page 3 of 4
Variability with outdoor samples over short time spans and changing weather conditions can occur, which may result in a lack of confidence in the data when comparing outdoor to indoor samples. When necessary, PRIME Engineering & Environmental Building Services utilizes a national accredited laboratory database of typical outdoor fungal concentrations to compare indoor to outdoor samples as an aid in interpreting conditions along with the other important aspects of an assessment, including but not limited to visual observations and moisture mapping. Indoor environmental quality is an individual responsibility, awareness and action improves the indoor environment significantly. It is recommended to have your indoor environment evaluated periodically to reduce potential for problems in the future. Sincerely, Gregory J.

The categories of Light, Moderate, Heavy and Too Heavy for Accurate Count, are used to indicate the amount of deposited debris. Increasing amounts of debris will obscure small spores and can prevent spores from impacting onto the slide. The actual number of spores present in the sample is likely higher than reported if the debris estimate is Heavy or Too Heavy for Accurate Count. All calculations are rounded to two significant figures and therefore, the total percentage of spore numbers may not equal 100%. * Minimum Detection Limit. Based on the volume of air sampled, this is the lowest number of spores that can be detected and is an estimate of the lowest concentration of spores that can be read in the sample. NA = Not Applicable. Percent of Total Spores that were observed from the samples submitted are listed on this report. If a spore is not listed on this report it was not observed in the samples submitted. Interpretation Guidelines: A determination is added to the report to help users interpret the mold analysis results. A mold report is only one aspect of an indoor air quality investigation. The most important aspect of mold growth in a living space is the availability of water. Without a source of water, mold generally will not become a problem in buildings. These determinations are in no way meant to imply any health outcomes or financial decisions based solely on this report. For questions relating to medical conditions you should consult an occupational or environmental health physician or professional. CONTROL is a baseline sample showing what the spore count and diversity is at the time of sampling. The control sample(s) is usually collected outside of the structure being tested and used to determine if this sample(s) is similar in diversity and abundance to the inside sample(s). ELEVATED means that the amount and/or diversity of spores, as compared to the control sample(s), and other samples in our database, are higher than expected. This can indicate that fungi have grown because of a water leak or water intrusion. Fungi that are considered to be indicators of water damage include, but are not limited to: Chaetomium, Fusarium, Memnoniella, Stachybotrys, Scopulariopsis, Ulocladium. NOT ELEVATED means that the amount and/or the diversity of spores, as compared to the control sample and other samples in our database, are lower than expected and may indicate no problematic fungal growth. UNUSUAL means that the presence of current or former growth was observed in the analyzed sample. An abundance of spores are present, and/or growth structures including hyphae and/or fruiting bodies are present and associated with one or more of the types of mold/fungi identified in the analyzed sample. NORMAL means that no presence of current or former growth was observed in the analyzed sample. If spores are recorded they are normally what is in the air and have settled on the surface(s) tested.

Commonly grows on Type III (hypersensitivity Found on dead and dying plant window sills, textiles and foods. pneumonitis) allergies. litter, and soil. Curvularia Ascospores Basidiospores Penicillium/Aspergillus Rusts Unidentified Spores Commonly found everywhere on soil and plant debris. Common everywhere. Constitutes a large part of the airspora outside. Can reach very high numbers in the air outside during the spring and summer. Can increase in numbers during and after rainfalls. Commonly found everywhere, especially in the late summer and fall. These spores are from Mushrooms. Common everywhere. Normally found in the air in small amounts in outdoor air. Grows on nearly everything. Common everywhere growing on grasses, trees and other living plants. Common everywhere. Grow on decaying plant litter and other plant-derived material. Capable of growing on many cellulytic substrates like wallboard and wood. Very few of this group grow inside. The notable exception is Chaetomium, Ascotricha and Peziza. Mushrooms are not normally found growing indoors, but can grow on wet lumber, especially in crawlspaces. Sometimes mushrooms can be seen growing in flower pots indoors. Wetted wallboard, wood, food, leather, etc. Able to grow on many substrates indoors. Does not grow indoors. Wetted cellulosic material. Type I (hay fever and asthma) and common cause of allergenic sinusitis. Little known for most of this group of fungi. Dependent on the type (see Chaetomium and Ascotricha). Some allergenicity reported. Type I (hay fever, asthma) and Type III (hypersensitivity pneumonitis). Type I (hay fever and asthma) allergies and Type III (hypersensitivity pneumonitis) allergies. Type I (hay fever and asthma) allergies. None known. Comments A very common and important allergen source both outdoors and indoors. Among the group of Mushrooms (Basidiomycetes) are dry rot fungi Serpula and Poria that are particularly destructive to buildings. This is a combination group of Penicillium and Aspergillus and is used when only the spores are seen. The spores are so similar that they cannot be reliably separated into their respective genera. Rust requires a living plant host to complete part of its lifecycle and thus, is not normally found growing indoors except perhaps on an infected house plant. This group of spores is reserved for spores whose identity is unknown. These kinds of spores have usually never been seen before in spore traps by our laboratory and/or are of such morphology that they cannot be identified with any degree of certainty to a particular genus.
