Report :Horry y Schools (St. James Elementary) Project No. 2019015 January 29, 2019 Mold spores were amplified in Rooms P107, P102, P105, P103, A110, E100, K102, Portable 220, I111 (Multipurpose), A106, P109, Portable 197, A105, A107, A109, A111, the Reading Room, Portable 286, M100 (Media Center - Nonfiction area), M104, P100, P118, and P114 on the day of our visit. Recommendations are provided in the Conclusions and Recommendations section of this report. Scope of Work conducted indoor air quality testing throughout St. James Elementary School in Myrtle Beach, SC on January 21, 2019. The purpose of the sampling was to determine if airborne mold spores were elevated above outdoor levels. We conducted a walk-through visual assessment, environmental parameter testing, surface and air sampling for mold spores during our visit. Materials and Methods Environmental Parameters Carbon dioxide (CO2), temperature and relative humidity were measured using a TSI IAQ Calc direct reading instrument to determine the relative comfort parameters of the subject area and to evaluate conditions that may promote amplification of microorganisms. The American Society for Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) has established guidelines for selected indoor air quality parameters such as temperature, relative humidity (RH) and carbon dioxide (CO2). These environmental parameters are important determinants for occupant s perceptions of thermal comfort, and ASHRAE Standard 55-2004 recommends ranges for temperature and RH that most occupants (>80%) will find comfortable. Acceptable temperature ranges differ from winter to summer and are a function of RH levels that range between 30% and 60%. RH below 30% is unacceptable because of the effect of dry air on the eyes, skin and mucous membranes, and RH above 60% may support the growth of pathogenic or allergenic microorganisms indoors. The following temperature ranges are considered acceptable based on the standard: Summer: 74ºF to 80ºF (for RH = 30%) and 73ºF to ºF (for RH = 60%). Winter: 69ºF to 76ºF (for RH = 30%) and 68ºF to 74ºF (for RH = 60%) The indoor concentration of CO2 is a surrogate for occupant-generated pollutants that may be odorous, and is an indicator of the adequacy of the rate of outside air supply per occupant (dilution ventilation). The higher the indoor concentrations of CO2, the less effective the ventilation system is in dilution of typical indoor air contaminants and body effluents. ASHRAE standard 62.1-2010 recommends an indoor to outdoor differential concentration of CO2 to be no greater than 700 parts per million (ppm) to meet comfort (odor) criteria., LLC! 5
Report :Horry y Schools (St. James Elementary) Project No. 2019015 January 29, 2019 Mold Samples (viable and non-viable) airborne fungal (mold) spores were measured indoors and outdoors using Zefon Air-O-Cell spore traps with a calibrated vacuum pump. Air sampling was performed indoors and outdoors for comparison. The samples were immediately shipped for overnight delivery and analyzed by light microscopy for viable and non-viable mold spores by Scientific Analytical Institute, which is accredited by the American Industrial Hygiene Association (AIHA). Surface sampling for mold was conducted by swabbing a surface of interest with a sterile swab. The samples were immediately shipped for overnight delivery and analyzed by light microscopy for viable and non-viable mold spores by Scientific Analytical Institute, which is accredited by the American Industrial Hygiene Association (AIHA). Microbial testing as a part of this report included testing and analysis for some biological agents commonly present in indoor air. It did not include testing and analysis for all known biological agents. Testing for biological contaminants does not include viruses or bacteria, unless specifically noted otherwise, and then only those viruses and bacteria specified. Results and Discussion Visual Assessment We were asked to collect air samples for mold throughout St. James Elementary School in Myrtle Beach, SC on January 21, 2019. The following observations were made at the time of our visit. We observed mold on the HVAC supply diffusers in Room E107, the K Workroom, and Portable 197, as well as on a soft Syracuse binder in Room A111. We did not detect any musty odors in any of the ares visited on January 21, 2019 at the time of our visit. We observed water stained ceiling tiles in the following rooms: Conference Room A100, A104, K103, K104, P107, M103, M104, P115, P120, IC100, I104, I109, I108, I110, and A110. We observed staining and/or dust build up on the HVAC supply diffusers in the following rooms: A103, E107, K105, K Workroom, P109, P107, I100, IC100, I101, I103, I102, I104, I107, I106, I109, I108, Portable 220, I110, I112, I111, Portable 197, Portable 311, Portable 215, Portable 286, Portable 141, Portable 194, Portable 185, A105, A107, A109, A110, I Workroom, and the Cafeteria.

We observed dust accumulating on the edges of the metal ceiling tile brackets (mainly in front of the HVAC supply diffusers) in the following rooms: E101, E105, I100, and IC100. We observed an accumulation of dust on the retractable screen in Room P116. Efflorescence (a white chalky powder) was observed on the exterior concrete walls in Rooms P109, P115, P116, P117, and I104. Efflorescence is caused by soluble salts, which are pushed to the surface by water intrusion into the concrete., LLC! 6
Report :Horry y Schools (St. James Elementary) Project No. 2019015 January 29, 2019 We observed rust on the HVAC wall units in Rooms P105 and A113. We observed staining on the ceiling, likely from prior water damage, in Portable 215 and Portable 205. We observed a small amount of dust/dirt on the concrete block walls in Rooms A109, I112, I103, and the Cafeteria. In the Cafeteria, the dust/dirt was around the HVAC supply diffusers, as well as on the concrete block columns in the middle of the Cafeteria in front of the HVAC supply diffusers.

Report :Horry y Schools (St. James Elementary) Project No. 2019015 January 29, 2019 Mold Samples We are unaware of regulatory requirements pertaining to mold associated with indoor air quality at this time. However, there are recognized guidelines for mold remediation from the Environmental Protection Agency (EPA), and New York City Department of Health Bureau of Environmental & Occupational Disease Epidemiology. Additionally, indoor air quality guidelines have been suggested for remedial decision-making by the Occupational Safety and Health Administration (OSHA), and the American Conference of Government Industrial Hygienist (ACGIH). Some of these guidelines focus on indoor to outdoor comparison, and an evaluation of fungal types. The interpretation of the results normally relies upon the professional conducting the assessment. Airborne microorganisms are ubiquitous; the presence of microorganisms is of undue concern unless they are of a significant concentration or the predominant types found indoors differ from those found outdoors. When indoor levels are significantly elevated in relation to outdoor concentrations, they are considered to be amplified. Therefore, indoor environmental conditions are such that their growth is facilitated. In general, amplification of microorganisms is present when the fungi or bacteria concentration in the air substantially exceeds the outdoor air. Exposure to excessive amounts of some common microorganisms can result in allergic or respiratory irritation in some susceptible individuals. Air sampling was performed indoors and outdoors for comparison. fungal spore (nonviable and viable fungi) concentrations were monitored. Summary results of the air samples are provided in Table II and actual laboratory results are provided in the Appendix., LLC! 11
