Categories of Water:Categories of Water:
Category 1 (Clean) Category 2 (Gray) Category 3 (Black)
• Originates from Sanitary Water Source
• No substantial risk from exposure
• Examples: Broken water supply line Tub or sink overflow Broken toilet tanks Appliance malfunctions Melting ice or snow Falling rainfall
• Once Category 1 water leaves the exit point, it may not remain clean once it contacts other surfaces or materials.
• Contains significant contamination
• Has potential to cause sickness if consumed by humans
• Can contain unsafe levels of microorganisms as well as other organic or inorganic materials
• Examples: Discharge from dishwashers Overflows from soiled toilet bowls Seepage due to hydrostatic press. Broken aquariums Punctured water beds
• Category 2 water cleanliness can deteriorate for many reasons – contact with building materials
• Grossly contaminated
• Can contain pathogenic, toxigenic or other harmful agents
• Examples: Sewage Toilet backflows from beyond trap Ground surface water Water from rivers or streams Wind-driven rain from heavy storms
• Such water may contain silt, organic matter, pesticides, heavy metals, regulated metals, or toxic organic substances
The cleanliness of water changes over time and requires a prompt response!
Proper and aggressive drying methods hinder amplification!

B … it is not responded to promptly, microorganisms will amplify. While the amplification will not be immediately noticeable, the greater the length of time, the greater the amplification.
C With the passage of time, microorganisms present in any category of water intrusion will begin to amplify.
FACT: Bacteria and mold spores are always present in the indoor environment.

Classes of water:Classes of water:Class 1 (least amount of water, absorption and evaporation)• Water losses that affect only part of a room or area• Large areas with materials that have absorbed minimal moisture• Little or no wet carpet and/or cushion present
Class 2 (large amount of water, absorption and evaporation)• Water losses that affect at least an entire room of carpet and cushion• Water has wicked up walls less than 24”• Moisture remaining in structural materials
Class 3 (greatest amount of water, absorption and evaporation)• Water may have come from overhead• Ceilings, walls, insulation, carpet, cushion and sub-floor saturated
Class 4 (specialty drying situations)• Consist of wet materials with very low permeance/porosity• Hardwood, plaster, brick, concrete, lightweight concrete and stone• Typically deep pockets of saturation which require very low specific humidity• May require longer drying times and special methods
