4 1.0 EXECUTIVE SUMMARY 1.1 Scope of Work Environmental Solutions Specialists, Inc. was retained by Ms. Kelly Howard, City of Shawnee/Human Resources Department, to conduct an Indoor Air Quality Investigation at Shawnee City Hall, 222 N. Broadway, Shawnee, Oklahoma. Environmental Solutions Specialists, Inc. (ESS) was contacted to determine if there is an air quality problem in the building due to mold, which can cause allergic reactions. On February 5 and 13, 2009, Wes Anderson, with ESS, collected ten indoor air samples to determine the air quality of the building as it relates to mold. All samples collected were submitted to EMSL Laboratories. Five samples that were collected utilizing an air pump with a PCR cassette were submitted for Trichothecene Mycotoxin analysis and five samples were collected utilizing an Anderson Sampler with an MEA Agar (Fungi) plate to determine if a viable (living) Stachybotrys fungus (mold) was present that is known to produce the Mycotoxin Trichothecene. 1.2 Site Background The Shawnee City Hall is a one story concrete block building with a basement located at 222 N. Broadway in Shawnee, Oklahoma. The building age is unknown, for this report. The Shawnee City Hall is occupied by the Town Clerk, administrative personnel, public works, and police department. The City Hall Basement is mainly utilized by the Shawnee Police Department. There was an historical pipe leak that occurred and impacted the Criminal Investigation Division (CID) Office and an area outside the hallway within the basement near the building elevators. The reason for the inspection involves an employee who has filed a workers compensation claim alleging exposure to Trichothecene Mycotoxin produced by a Stachybotrys fungi (mold). Several additional Indoor Air Quality Investigations were conducted by others to determine the same. The investigation conducted by ESS was in five areas, chosen by the client and based on previous investigations. These areas were the CID Office, Uniform Division Supervisor Office, Police Records and Information Hallway, Hallway Outside Room 116A, and First Floor Foyer (See Attached Building Layout).

5 1.3 Findings On February 5 and 13, 2009 site walks were conducted of the areas of concern. Those present during sampling were Ron Baze, Attorney representing Kent Borcherding, Matt Love, Attorney representing The City of Shawnee, and Wesley Anderson, with Environmental Solutions Specialists, Inc. On February 5, 2009 Wesley Anderson, with ESS, conducted one air sampling utilizing an air pump to draw a volume of air through a PCR cassette in each area. Approximately 50 liters of air volume was run across the sample media of the PCR cassette in order to collect particulate matter that may contain the Mycotoxin Trichothecene. In conjunction an Anderson Sampler was utilized with an MEA Agar (Fungi) plate to determine if any other viable (living) fungi (mold) was present that has the potential to produce other Mycotoxins, one air sample per area was conducted. Samples were submitted to EMSL Laboratories to the attention of Dr. Zeljko for analysis and identification. Dr. Zeljko reported that 50 liters of air was not enough air volume to collect a sufficient sample of debris (particulate) in the PCR cassette. Dr. Zeljko requested that a minimum of 1,000 liters of air would be needed in order to collect a large enough sampling of particulate in the PCR cassette. On February 13, 2009, Wes Anderson, with ESS, resampled the five areas utilizing an air pump and PCR Cassette to submit for Mycotoxin Analysis. Per Dr. Zeljko s recommendation 1,000 liters of air volume was ran through the PCR Cassette. No additional samples were collected for viable mold based on findings. All samples collected were submitted to EMSL Laboratories. Sampling was conducted during normal business hours for all air sampling, approximately 9:30 am to 12:30 pm. All samples collected were submitted to EMSL Laboratories to the attention of Dr. Zeljko for analysis and identification. Below are the results and in Appendix B, Laboratory Analysis Viable Fungi Results On February 5, 2009 Wesley Anderson, with ESS, conducted air sampling utilizing an Anderson Sampler with an MEA Agar (Fungi) plate to determine if any other viable (living) fungi (mold) was present that has the potential to produce other Mycotoxins, one air sample per area was conducted. Anderson Sampling device was set at 28.3 liters per minute for 5 minutes per location. Below are the results and in Appendix B, Laboratory Analysis.

6 Results of testing did not indicate the presences of Stachybotrys fungi at the time of testing. Aspergillus and Penicillium genera of fungi can produce Mycotoxins. * Mycotoxins are fungal metabolites that have been identified as toxic agents.

7 1.3.2 Mycotoxin Sample Results On February 13, 2009 Wesley Anderson, with ESS, conducted air sampling utilizing a calibrated air pump and a PCR Cassette to be submitted for Mycotoxin Analyisis Total Trichothecenes by ELISA. one air sample per area was conducted. The two Sampling devices utilized were set at 29 liters per minute and 25.5 liters per minute, run time approximately 35 minutes and 39 minutes. The total volume of air recorded per sample 1,000 liters. Below are the results and in Appendix B, Laboratory Analysis. Results of testing indicated Non Detect for Total Trichothecenes. * Mycotoxins are fungal metabolites that have been identified as toxic agents. 2.0 Conclusions At the time of sampling results of laboratory analysis of indoor air did not indicate the presence of Stachybotrys fungi or the presences of the Mycotoxin Trichothecene on the particulate matter collected in the areas of concern. Fungal identification did reveal the presence of Aspergillus and Penicillium genera of fungi which can produce Mycotoxins. But, these fungi are not associated with producing the Mycotoxin Trichothecene. Fungi colony counts for viable mold were higher in the Uniform Division Supervisor Office. It is possible this is due to at the time of sampling mold growth was observed on vegetable matter disposed of in trash can in the proximity of sampler.

13 APPENDIX C BIOLOGICAL CONTAMINANTS

14 BIOLOGICAL CONTAMINANTS Biological contaminants include bacteria, molds, mildew, viruses, animal dander, house dust mites, cockroaches, and pollen. There are many sources of these pollutants. Some biological contaminants trigger allergic reactions, including hypersensitivity pneumonitis, allergic rhinitis, and some types of asthma. Molds and mildews release disease-causing toxins. Symptoms of health problems caused by biological pollutants include sneezing, watery eyes, coughing, shortness of breath, dizziness, lethargy, fever, and digestive problems. Allergic reactions occur only after repeated exposure to a specific biological allergen. However, that reaction may occur immediately upon re-exposure or after multiple exposures over time. As a result, people who have noticed only mild reactions or no reactions at all may suddenly find themselves very sensitive to particular allergens. Children, elderly people, and people with breathing problem, allergies, and lung diseases are particularly susceptible to disease-causing biological agents in the indoor air. TEN THINGS YOU SHOULD KNOW ABOUT MOLD 1. Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints. 2. There is no practical way to eliminate all fungi and mold spores in indoor environment; the way to control indoor mold growth is to control moisture. 3. If mold is a problem in your building, you must clean up the mold and eliminate sources of moisture. 4. Fix the source of the water problem or leak to prevent mold growth. 5. Reduce indoor humidity (to 30-60%) to decrease mold growth by: venting bathrooms, dryers, and other moisture-generating sources to the outside; using air conditioners and dehumidifiers; increasing ventilation; and using exhaust fans whenever cooking, dishwashing, and cleaning. 6. Clean and dry any damp or wet building materials and furnishings within hours to prevent mold growth. 7. Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, those are moldy, need to be replaced. 8. Prevent condensation: Reduce the potential for condensation on cold surfaces (i.e., window, piping, exterior walls, roof, or floors) by adding insulation. 9. In areas where there is a perpetual moisture problem, do not install carpeting. 10. Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.
