MOLD SCREENING REPORT
Section 1 General:
Subject: Mold Screening Report
Date: 4/22/2015 Time: 3:00 PM
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

Louisville, KY 40220
Section 2 Method:
A visual inspection of a classroom 307 complaint area was completed based on the Indoor Environmental Standards Organization, Standards of Practice for the Assessment of Indoor Environmental Quality.
One air sample was collected in a complaint area, one in a non-complaint area, and one outdoor control sample. (note: This was not a full building indoor air quality survey).
Air sample medium: Micro 5 spore trap cassettes
Surface sample medium: Mold Tape SlideTM

Section 3 Findings:
Surface mold was detected as follows: Location and list of all spore types
detected on sample:
Room 307 (HVAC coil fins): None Detected
Room 307 (Drywall wall): Stachybotrys
Room 307 (Carpet): None Detected
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.
Room 307 (complaint room): No amplified spore levels
Room 304 (non-complaint room): No amplified spore levels
Section 4 Discussion:
This scope of work included the inspection of only one complaint room, room
307. This room has been reportedly experiencing a chronic roof leak.
The perimeter drywall wall in this room exhibited water damage and many water
stains. The wall was still damp in many areas. The last rain event was reportedly
over 48 hours prior to the inspection.
A room inspection with a thermal imaging camera (Testo 865) revealed what
appeared to be a crack in the cinderblock wall beneath the window closest to the
HVAC closet. This is allowing cool air to seep in and may be a point of water
intrusion. The thermal camera also indicated high levels of moisture in the
drywall walls along the window wall.

Mold growth was observed and tested on the affected walls. Possible mold was
tested on the HVAC coil fins and carpet. Sample results did not indicate the
HVAC coil fins and carpet had mold growth. The stained ceiling tiles did not
appear to contain suspect mold growth, only water staining.
An odor was evident upon entering the complaint room 307. No odor was noticed
upon entering the non-complaint room 304.
The HVAC MERV-8 filters appear to have been recently changed and were in
acceptable condition.
Section 5 Conclusions/Recommendations:
It is recommended that roof, roof drainage, and roof coping caps undergo a
proper inspection/repairs and the exterior wall and window sills be inspected
for cracks, missing mortar, or other defects and repaired as necessary.
Following the source correction, the below recommendations are made
Since room 307 has undergone chronic water intrusion along the drywall window
wall. It is recommended that all 130 SF of drywall and insulation on the window
wall be removed. Following drywall removal, all remaining surfaces in the open
affected void should be scrubbed clean and a microbial inhibiting agent applied.
The front wall of room 307 that intersects the window wall has been affected at
the corner. It is recommended that, at a minimum, the affected drywall be
removed at least 1 linear foot from the corner and the full height to the ceiling
(approximately 12’ high). Regardless, EHM recommends removing the drywall
at least 1 linear foot beyond any visual mold growth. (approximately 20 SF total
affected on front wall).
Based on the air sample results, the mold on the walls has not adversely impacted
the mold levels in the air.

* um = means particle size in microns (1000 microns = 1 millimeter). ** Bold number indicates elevated levels of particles when compared to the outdoor readings. Though the particulate levels between 0.5 um and 5 um were elevated when compared to outdoors, it is important to note that there was high foot traffic in these classrooms as school had released students just prior to this inspection. This may be the source of the higher particle levels. The elevated carbon dioxide levels are normally related to high concentration of personnel versus a lack of fresh air.
