More About Flooding- Types and Categories of Water Damages

Category 1- Clean Water
Originates from a source that does not pose substantial harm to humans.
Examples: Broken water supply lines, tub and sink overflows with no contaminants.
May deteriorate in cleanliness as it dissolves or mixes with soils and other contaminants, and as time elapses. 

Category 2- Gray Water
Contains a significant level of contamination and has the potential to cause sickness if consumed.
Carries microorganisms and nutrients for microorganisms.
Examples of gray water sources may include discharge from dishwashers or washing machines, overflows from toilet bowls with urine.
May contain chemicals, biocontaminants (fungal, bacterial, viral, algae) and other forms of contamination including physical hazards.
If gray water remains untreated for longer than 48 hours it may change to a category 3.
