August 9, 2019 Mr. Nels Strickland Assistant Director Department of Housing University of Mississippi P.O. Box 1848 University, Mississippi 38677 Re: Indoor Air Sampling for Mold Crosby Hall, Stockard Hall and Martin Hall Dear Mr. Strickland:

This Indoor Air Sampling for Mold Report presents analytical data for samples collected during

four separate sampling events conducted at Crosby Hall on July 23 and 24, 2019, Stockard

Hall on July 30, 2019, and Martin Hall on July 31, 2019. Each of the buildings were

unoccupied. However, at Stockard Hall final construction cleanup activities that included floor

and ceiling tile replacement, wall painting, etc. in various were in progress on the sixth and

seventh floors owing to a serious water leak that was discovered on the seventh floor during

June. At Martin Hall, final cleanup activities, i.e, floor waxing and housekeeping and minor

repairs were in progress following the completion of the installation of variable air ventilation

systems on each floor of the building. At Crosby Hall, limited final housekeeping activities were

ongoing at various floors within the building as efforts to ready the building for student

occupancy were underway.

METHODOLOGY

At each spore trap sampling location, a spore trap sampler cassette was attached to an air

vacuum pump set at 15 liters per minute for a period of five minutes yielding a filter media

sample impacted with 75 liters of sampled air. At the start of each day of sampling, an outdoor

sample was collected so as to provide comparison of ambient fungal species with those

identified during the indoor air sampling events. Samples were delivered via overnight carrier

to EMLab PK Laboratories in Marlton, New Jersey. A copy of the laboratory reports and chain

of custody documents are presented in Attachment 1.

DISCUSSION Background

The review of air sample results for fungi is generally limited to the comparison of indoor air

sample results to outdoor air sample results; and, in many cases, results from one area indoors

are compared with results from other areas that may exhibit differences in air quality conditions

such as temperature and humidity and, consequently, the presence of mold. Areas suspected

to contain high levels of fungi due to the presence of mold may be compared to areas where

contamination is known to be absent. For the purposes of this report, the word contaminant is

defined as any fungi discovered during the sampling process that is indicative of active fungal

growth indoors.

Presumptive identification of captured spores on spore trap cassettes, i.e., visual identification

through a microscope, is used to compare species of fungi in each sample. In most

investigations, comparisons are made with samples from control (uncontaminated) areas to

those from suspected contaminated areas. In these investigations, if similar genera of fungi

are found in background samples from control areas as well as in those samples from

suspected contaminated areas, then the quantity of fungal material in the samples is compared

to determine differences. For instance, levels greater than 80% of the control air samples

would indicate a possible amplification of the identified fungal genus. Similarly, in these types

of investigation indoor samples are compared to outdoor samples. If different genera are

identified indoors than those found in outdoor samples, it may be concluded that there is a

reservoir of contamination indoors, but this conclusion also depends on the significance of the

quantity of the measured fungal population. In areas where the air exchange with outdoor air

is consistent, one would expect to find similar genera although at much lower concentrations.

In the present investigation, indoor sampling was conducted to provide a background data

base to demonstrate existing conditions prior to the occupancy of the dormitory halls. Hence,

there were no control samples collected for comparison but rather an evaluation of the data

among all collected samples. Nonetheless, collection of outdoor samples was conducted as a

baseline for comparison with the indoor sampling data and it was observed that outdoor total

spore counts far exceeded the greatest spore count observed among any of the samples

collected indoors. Whereas outdoor concentrations were observed at 8,500, 18,000, 23,000

and 27,000 Spores/M3, the indoor samples generally ranged from 53 to 960 Spores/M3.

Among the 215 samples collected, there were 12 samples that ranged from 1,000 to 3,200

Spores/M3 and in three locations concentrations were observed at 4,200, 5,200 and 13,000

Spores/M3 as seen in the tabulated analytical results, above. Although these differences in

total spore concentrations were significant from room to room, in absolute terms they would not

be considered harmful to the general population.



_____________________________________________________________________________________________

RESULTS

Crosby Hall

Among 95 samples collected, the average concentration was observed to be 313 Spores/M3

discounting the outlier concentration of 4,200 Spores/M3 that was observed in Room 548. As

noted in Table 1, the concentration of Basidiospores (3,000 Spores/M3) was noted to be the

major contributor to the increased concentration. This genus generally is characteristic of

outdoor fungi. A concentration of 16,000 Spores/M3 was observed in the outdoor sample.

Though not noted during the sampling event, it may be likely that a window was opened at the

time of sample collection. No other significant conditions were noted in the room that would

have materially increased the concentration of spores in that room.

Stockard Hall

Among 60 samples collected, the average concentration was observed to be 627 Spores/M3,

discounting the outliers of 5,200 and 13,000 Spores/M3 that were observed at rooms 819 and

606, respectively. As noted in Table 1, the concentrations of Aspergillis (4,600 and 9,700

Spores/M3 observed in Rooms 819 and 606, respectively) contributed to the increased

concentrations observed in these room. These genera are not normally characteristic of

outdoor fungi. A concentration of 750 Spores/M3 was observed in the outdoor sample.

Aspergillis is normally associated with moisture. Although no significant conditions were noted

in the room at the time of sample collection, it may be assumed that the presence of a source

of moisture contributed to the elevated concentration in Room 606 particularly.

Martin Hall

Among the 60 samples collected from Martin Hall, the average concentration of all samples

was observed to be 229 Spores/M3. There were no significant outliers among the observed

concentrations. It was noted that housekeeping activities were nearly complete within the

building

CONCLUSION

Total concentrations of spores observed in spore trap samples collected from the indoor

locations, in absolute terms, are low. The relatively higher concentrations of total spores

observed in certain rooms were found to be the result of increased concentrations of

Basidiomycetes and Aspergilllis. Both fungi are responsive to damp conditions, however the

presence of Aspergillis is more indicative of interior conditions as opposed to outdoor

influences found to contribute to the presence of Basidiomycetes.

The highest observed value of Aspergillus (9,700 Spores/M3) in terms of its absolute

concentration is not considered a health risk although it may indicate the potential for growth

should a source of moisture be present. Concentrations ranging from 20,000 Spores/M3 to

100,000 Spores/M3 and greater have been shown to indicate accelerated mold growth activity

that could illicit a physical response (wheezing, stuffiness, etc.) in the more sensitive human

population.

Based on the absence of mold on wall surfaces, it is recommended that a thorough

housekeeping effort be conducted on the rooms exhibiting outlier concentrations of mold.

MoldRANGE™, Local Climate; Extended Outdoor Comparison

¹EMLab Regional Climate codes are a climate classification scheme for regional geographic areas containing multiple states. The MoldRANGE™ Local Climate report uses the sampling location zip code to identify the EMLab Regional Climate code in that area. Using information available from the NOAA weather database, the EMLab Regional Climate code sharpens the precision of the MoldRANGE™reporting system, providing more reliable estimates of the range and average concentrations of the different airborne fungal spore types for each region. Additional information on the EMLab Regional Climate code system can be found on the last page of this report.

†The Typical Outdoor Data represents the typical outdoor spore levels across the region's group of states for the time period and EMLab Regional Climate code indicated. The last column represents the frequency of occurrence. The very low, low, med, high, and very high values represent the 10, 20, 50, 80, and 90 percentile values of the spore type when it is detected. For example, if the frequency of occurrence is 63% and the low value is 53, it would mean that the given spore type is detected 63% of the time and, when detected, 20% of the time it is present in levels above the detection limit and below 53 spores/m3. These values are updated periodically and if not enough data is available to make a statistically meaningful assessment, it is indicated with a dash.

‡ n is the sample size used to calculate the MoldRANGE™ Local Climate data summarized in the table.

* The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces rapidly and are very easily dispersed. Other genera are usually present in lesser numbers.

** These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens. However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts ofa single morphological type of basidiospore on an inside sample should be considered significant.

§ Total Spores/m3 has been rounded to two significant figures to reflect analytical precision.





Understanding EMLab Regional Climate CodesOutdoor airborne spore concentrations are strongly influenced by climate and weather patterns, often resulting in pronounced seasonal and diurnal cycles (Burge 1995). The seasonal climatic changes directly affect the growth cycle of plants, thereby influencing fungal growth, spore maturation, and release cycles. By evaluating outdoor spore concentrations across similar climatic zones rather than for the state as a whole, it is possible to provide a more representative estimate of typical outdoor spore levels and frequency of occurrence for different airborne fungal spore types in a given area.

The EMLab Regional Climate code system is a novel and patent pending classification system that uses data from the NOAA - National Oceanic and Atmospheric Administration database to define unique climate zones. The following climate variables, for each regional zip code, are obtained from NOAA and assigned a letter code of A (above the regional average for that variable) or B (below the regional average for that variable):

1. Annual High Temperature2. Elevation3. Rainfall/Precipitation4. Monthly Temperature Range

The result is a 4-character code assigned to each statewide zip code, referred to as the Regional Climate Code. Below are some examples of decoded Regional Climate Codes:

AAAA = Above avg. Annual High Temperature, Above avg. Elevation, Above avg. Rainfall/Precipitation, Above avg. Monthly Temperature RangeAABB = Above avg. Annual High Temperature, Above avg. Elevation, Below avg. Rainfall/Precipitation, Below avg. Monthly Temperature RangeBBAA = Below avg. Annual High Temperature, Below avg. Elevation, Above avg. Rainfall/Precipitation, Above avg. Monthly Temperature Range

The actual outdoor air sample data from matching regional climate codes in each group of states are then compiled in a manner relating typical spore concentrations and frequency of occurrence.

The data presented in this report is from the South Region which includes the states of: AR, KS, LA, MS, OK, and TX

The NOAA regional climate variables were selected by mapping data points from a subset of approximately 145,000 weather and geographic database entries to over 80,000 outdoor spore trap samples with known zip codes and assessing them using orthogonal array experimental design techniques. The results were then compared to the typical ranges of spore types found when grouping zip codes using the Koppen-Geiger climatic classification system; a commonly used climatic system that provides an objective numerical definition in terms of climatic elements such as temperature, rainfall, and other seasonal characteristics . The EMLab Regional Climate codes showed improved granularity and refinement of the zip code groupings, implying a better representation of the expected range of spore types to be found within an individual zip code.

The values on this report were calculated by obtaining the four variables listed above from the over 585 million data points of weather and geographic information available in the NOAA database, and determining the frequencies and percentile values of spore types by utilizing over 180,000 EMLab P&K outdoor spore trap samples with known zip codes.

This report groups regional zip codes in relation to these EMLab Regional Climate codes and summarizes MoldRANGE™ data by month and year within each EMLab Regional Climate code.
