Why Flood Water Is Referred To As Black Water

When flooding enters a commercial building in Birchwood, TN, restoration professionals identify the incident as Category Three water damage. Learn more about what this categorization means and find out why flood water is referred to as black water.

Contaminants In Water

Category Three water is grossly contaminated. The reason this type of water damage is called black water is that it may contain any of the following substances:

• Heavy metals
  
• Pathogens
  
• Solid waste
  
• Toxic chemicals
  
  

The presence of solid waste along with these other hazardous materials distinguishes Category Three damage from Category One water damage caused by clean, treated water that gets released from a broken or leaking supply line. Category Two gray water may be contaminated with chemicals or microbes, but does not contain solid waste.

Saturated Porous Materials

Porous building materials and contents that become saturated with flood water may be difficult to disinfect. Even after treating the surfaces of these items, contamination may linger deeper down and lead to ongoing contagion or mold infestation risks. For this reason, restoration professionals often recommend tearing out drywall, insulation and carpeting.

Flooding Causes Mold

Storm damage that involves flooding can introduce all of the elements necessary to support mold growth. Mold requires moisture and organic, carbon-based food sources in order to multiply. Category Three water can provide sources of nourishment and introduce spores into a structure. It is important to extract water, tear out ruined materials, disinfect and dry any areas exposed to flooding within 24 to 48 hours.
The contents of Category Three water can pose contamination risks to building materials, contents and occupants. It is important for property owners and managers to act quickly to remove floodwater, disinfect areas exposed to black water and tear out damaged materials. Mold may start growing in a commercial building within just 48 to 72 hours after flooding in Birchwood, TN.
