Water damage is divided into three general classes: Class 1-Clean Water; Class 2-Gray Water; and Class 3-Black Water. The class of the water contamination is not determined by the color of the water, it is determined by the source, contents, history and characteristics of the water.
Class 1 – Clean Water
Clean water comes from a source that does not pose substantial harm to humans. Examples include, but not limited to, broken supply pipes and appliance malfunctions. Clean water in flooded structures that remain untreated may change to class 2 water in as little as 48 hours and class 3 water in as little as 96 hours.
Class 2 – Gray Water
Gray water contains a significant level of contamination and has the potential to cause discomfort and sickness if consumed by or exposed to humans. Examples include, but not limited to, discharge from dishwashers or washing machines, overflows from washing machines, overflows from toilet bowls with some urine (no feces), and sump pump failures. Gray water in flooded structures that remain untreated may change to Class 3 water in as little as 48 hours.
Class 3 – Black Water
Black water contains pathogenic agents and is grossly unsanitary. Black water includes sewage and other contaminated water. Toilet back-flows that originate from beyond the toilet trap is considered black water, regardless of visible content or color. Black water includes all forms of flooding from ground surface water and rising water from streams and rivers. Such water sources carry silt and organic matter into structures and create black water conditions.
Microorganismsare always present in the indoor environment. To prevent amplification of microorganisms, immediate response is necessary for all classes of water intrusion.
