Remediation
Indoor Environmental Professional (IEP): an individual who is qualified by education, training and experience to perform an assessment of the fungal ecology of property, systems and contents of a job site, create a sampling strategy, sample the indoor environment, interpret laboratory data and determine Condition 1, 2, and 3 status for the purpose of establishing a scope of work and verifying the return of a fungal ecology to a Condition 1
ANSI/IICRC S520
Category 1 – Clean Water à Originates from a sanitary water source and does not
pose substantial risk from dermal, ingestion or inhalation exposure…
Category 2 – Gray Water à Contains significant contamination and has the
potential to cause discomfort or sickness if contacted or consumed by humans…
Category 3 – Black Water à Grossly contaminated and contains pathogenic,
toxigenic or other harmful agents…

Condition 1 – normal fungal ecology à May have settled spores, fungal fragments or traces of actual
growth whose, identity location and quantity is reflective of normal fungal ecology for an indoor environment.
Condition 2 – settled spores à An indoor environment which is primarily contaminated
with settled spores that were dispersed directly or indirectly from a Condition 3 area, and which may have traces of actual growth.
Condition 3 – actual growth à An indoor environment contaminated with the presence of
actual growth and associated with spores…

Fungi – no water, no growth
Bacteria – nearly every water loss Viruses – bloodborne or through water in sewage

Fungal Growth
Category 3
Category 2
Category 1
Fungi à Are present in nearly every living environment à Some are toxic à Others have medicinal qualities à While others help age food à Spores range in size from 2 – 20 microns à Require a food source and moisture to germinate à Some fungi can germinate in as little as 48 hours
6
10/26/2011
Bacteria à Duplicate (exponentially) à Can begin to duplicate in as little as 1 – 3 hours à Measure .4 – 10 microns in size à Commonly found in water damage jobs E. Coli Salmonella Tetanus
Viruses à Measure .03 to .25 microns in size à Require a host organism à Take over living cells and replicate themselves à Can be found in sewage Hepatitis A, B, C and E HIV

Ultimate Goal
Steps 1 and 2
Steps 3 and 4
Steps 5 and 6
Identify and correct the source of moisture
Set up containment and Establish negative air
Clean surfaces
Establish the scope of work
Remove contaminated building materials
Post remediation evaluation and testing

Identify and correct the source of moisture
What is the origin of water? What was it’s path of travel? Has the problem been fixed?
Establish the scope of work
Determine the entire affected area? Determine un/affected contents? Determine un/affected domestic systems?
Set up containment and Establish negative air
Restoration Consultants, Inc.
Utilize 6 millimeter fire retardant “poly” sheeting Construct a proper / durable containment Use equipment in accordance to industry standards to create negative air pressure
Remove contaminated building materials
Don’t bash and trash Remove and transport affected building materials out of the affected area and building Dispose of properly

Clean surfaces
Post remediation evaluation and testing
Remove contamination Flush hard to reach areas Apply antimicrobial (if/when needed and in accordance with MSDS sheets) Detailed cleaning and or sanding Quality control 3rd party clearance Eliminates potential conflict of interest
The ultimate goal of remediation is to ensure that a structure can be reoccupied by it’s occupants without adverse reactions…
Mold remediation; à Is the effective removal of mold growth and settled spores to
a level that is less than or equal to typical background or outside levels
Sewage remediation; à Is the effective removal of all sewage related microorganisms
(zero pathogens) from contaminated surfaces or the physical removal and disposal of sewage saturated porous materials. à
