Understanding Flood Water: Clear Water, Gray Water, Black Water Wednesday, October 21, 2020

Floodwater can cause unsightly damage to your home or office building and to the contents inside, but it can be even more harmful to your health. Floodwaters can bring in contaminants, microorganisms, bacteria, and even raw sewage.

The Institute of Inspection Cleaning and Restoration Certification (IICRC) classifies water into three types: clear, gray, and black. Knowing what the color of your floodwater means is important so you can clean and dispose of the water safely. Learn about what each color means so you know how to best protect the health of yourself and others in the event of a flood.

Clean Water

Clean water is safe for human use and has no health threats. Toilet tank water, rainwater, and snowmelt are all examples of clean water. This kind of floodwater damage can happen from a burst pipe or if a toilet overflows. Flooding restoration for this type of water typically involves a thorough inspection of the flood damage, but there is less emphasis on treating contaminants. However, it's important to note that this does not mean clean water is safe to drink, bathe, or wash clothes and dishes with.

Gray water

Gray water is often an opaque shade of gray and indicates that there may be some contaminants that can cause health issues. This water can come from:

  • Showers
  • Dishwashers
  • Sinks
  • Bathtubs
  • Washing machines

Gray floodwater needs to be addressed within the first 48 hours before it has the chance to sit and harbor more contaminants and hazardous materials. This is where it can quickly change into black water.

Black Water

Black floodwater is incredibly hazardous to humans and requires a more intense remediation process to restore your home back to appropriate health standards. The increased exposure can be detrimental to human health. Raw sewage is a type of black water, and all black water contains contaminants such as bacteria, mold, viruses, and other diseases, such as:

  • Typhoid
  • Hepatitis
  • Cholera

The flood remediation process

The first step in remediation is to call us so we can start the cleanup process as soon as possible. The longer water sits, the more damage occurs and the more dangerous it can become for your health. The next task is to remove all water and make sure all areas are completely free of moisture.

Some parts of the house may be saved, while others need replacing. Drywall, cabinets, flooring, and even wooden beams may need to be completely replaced, especially if there is evidence of contaminated floodwater.
