Why Is Flood Water Called Black Water?
Category 3 black water refers to flood water or water that contains solid waste. This term is also used to describe stagnant water that supports the growth of bacteria. Find out what distinguishes Category 3 water from other types and why this type of water requires thorough cleaning, disinfection, and drying to reduce the risks of contagion or mold.
What Are the 3 Categories of Water?
Three categories of water can be involved in water damage.
- Category One water is clean, treated, and typically originates from a broken supply pipe.
- Category Two water or gray water may contain chemicals or microbes. This water can come from showers or appliances such as dishwashers or washing machines.
- Category Three water may contain solid waste or other dangerous contaminants. This water can cause illness when consumed, inhaled, or through skin exposure.
Is All Flood Water Considered Black?
It is safe to assume that water from flooding is Category 3. This water has a high chance of containing the following contaminants:
- Heavy metals
- Solid waste
Any parts of a building exposed to flooding due to storm damage should be cleaned and disinfected prior to being reopened to occupants and visitors.
What Are the Risks of Black Water?
In addition to posing an infection risk for humans and animals, Category Three water also raises the risk of mold growth. Mold may begin to develop in flooded areas within only 24 to 72 hours. It is necessary to eliminate the presence of standing water and solid waste, pre-treat the area, remove porous building materials that can absorb water, and then disinfect, dry, and restore the affected area.
