MOLD SCREENING REPORT

Section 1 General:

Subject: Mold Screening Report

Date: 5/01/2015 Time: 9:00 AM

Location: 269 Water Street, Mt. Washington, KY 40047

Inspection Contact: Mark Mitchell (Director of Facilities)

Inspector: Tony Ritenour, CMI (Council-certified Microbial Investigator)

Inspector’s Company Address: Environmental Health Management

3701 Taylorsville Road, Suite 1

Louisville, KY 40220

Section 2 Method:

A visual inspection of classrooms 214, 218, 308, 306, 305, and 303was completed in the student occupied areas and above the ceilings.

One air sample was collected in each classroom and two outdoorcontrol samples. (note: This building indoor air quality survey waslimited to the specific rooms listed above).

Air sample medium: Micro 5 spore trap cassettes



Section 3 Findings:Surface mold was detected as follows: Location and list of all spore types

detected on sample:

No surface mold was observed in any student occupied areas in classrooms

214, 218, 308, 306, 305, and 303.

Amplified indoor mold spore counts detected as follows: location and list

of amplified spore types detected on sample. “Amplification” means higher

than outdoor baseline or background levels (1-6 spores); unless

inspector/analyst renders opinion to the contrary.

No amplified airborne mold spores were detected in classrooms 214, 218, 308,

306, 305, and 303.

Section 4 Discussion:

This scope of work included the inspection of classrooms 214, 218, 308, 306, 305,

and 303 where students would usually be occupying the space. This inspection

excluded each room’s small mechanical closet that are usually locked and under

negative pressure.

Previous mold air testing took place in room 307 and 304. Those results indicate

those rooms did not contain amplified mold spore levels in the air.

Many rooms contained some sort of water damage, whether it was drywall walls

or ceiling tiles. Though water damage or stains were visible, there was no visible

suspect mold growth observed on the finished side of drywall or either side of

stained ceiling tiles.

The roof was undergoing corrective repairs during this inspection.

All walls were scanned with a thermal imaging camera (Testo 865) and cross

checked with a moisture meter (GE Surveymaster Protimeter). All walls and

ceiling tiles in the student occupied areas were dry.



Section 5 Conclusions/Recommendations:

The following recommendations are made:

It is recommended that the water damaged paint on drywall walls be properly

prepped and painted. If new paint begins to fail due to water damage, then the

roof repair in that area was not sufficient or there is another source of water

intrusion.

It is recommended that water stained ceiling tiles be replaced. If new ceiling tiles

become water stained, then the roof repair in that area was not sufficient or there

is another source of water intrusion.

Since the roof was undergoing repairs and no visible or amplified mold spores

were detected in the occupied portions of classrooms 214, 218, 308, 306, 305, and

303, then no further air testing of those rooms is recommended at this time.

If conditions should change or leaks continue, then further testing may be needed.



Section 6 References:

1 - The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) hasdetermined that acceptable ranges of temperature and relative humidity for the summer and winter are:

Relative Humidity Winter Temperature Summer Temperature

30 % 69.0oF - 78.0oF 76.0oF - 82.0oF

60 % 68.0oF - 75.0oF 74.0oF - 78.0oF

These standards apply for persons clothed in typical summer and winter clothing, at light, mainly sedentaryactivity. Source: Adapted from the ANSI/ASHRAE Standard 55-2010, Thermal Environmental ConditionsforHuman Occupancy.

2 - ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality, suggests thatcarbon dioxide levels be maintained at or below 700 ppm above the outside level to keep bioeffluents (bodyodor) within an acceptable level. The OSHA Permissible Exposure Limit for carbon dioxide is 5000 ppm.

3 - 2014 Threshold Limit Value (TLV) of the American Conference of Governmental Industrial Hygienistsfor carbon monoxide is 25 ppm. The OSHA Permissible Exposure Limit for carbon monoxide is 50 ppm.

4 - Investigating Fungal Contamination in Buildings, EMLab P & K, 2003, states that in general, indoorconcentrations of fungi and bacteria should be lower than outdoor levels.

5 - In the OSHA Technical Manual, OSHA considers indoor surface samples of 1,000,000 CFU/in2 orindoor air sample results of 1,000 CFU/m3 as an indication of contamination. OSHA Technical Manual,Chapter 2.

* um = means particle size in microns (1000 microns = 1 millimeter).** Bold number indicates elevated levels of particles when compared to the outdoor readings.

Though some particulate levels between 0.5 um and 10 um were elevated when comparedto outdoors, it is important to note that there was some foot traffic in the hallways asworkers removed furniture from classroom 307 prior to the inspection. Air testingshowed that no amplified mold spores were detected in the classrooms listed in the tables.

Initial report from: 05/05/2015 08:50:20

High levels of background particulate can obscure spores and other particulates leading to underestimation. Background levels of 5 indicate an overloading of background particulates, prohibiting accurate

detection and quantification. Present = Spores detected on overloaded samples. Results are not blank corrected unless othewise noted. The detection limit is equal to one fungal spore, structure, pollen, fiber

particle or insect fragment. "*" Denotes particles found at 300X. *-* denotes not detected. EMSL maintains liability limited to cost of anaysis. This report relates only to the samples reported above and may not
