The 3 Categories of Water Damage

9/5/2019 (Permalink)

There are 3 Basic Categories of Water

Category 1 originates from a sanitary source and poses no substantial risk from dermal, ingestion, or inhalation exposure. However, it may not always remain clean after it comes into contact with other surfaces or materials.

Category 2 contains significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans. It may contain potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter (chemical or biological).

Category 3 is grossly contaminated and may contain pathogenic, toxigenic or other harmful agents. Such water sources may carry silt, organic matter, pesticides, heavy metals, regulated materials, or toxic organic substances.

Time and temperature can also affect the quality of water, thereby changing its category. *Refer to the IICRC S500 for complete definitions.
