1. The water came from an extremely unsanitary source.

The best example of "black" water is sewage. It's thoroughly yucky and presents extreme hazards to human health. It's also the most common type of "black" water to cause damage, and can come from an overflowing toilet or from the sewer or septic system. However, there's another type of very hazardous water in this category, too: flood water. Whether it's the storm surge from a hurricane or seasonal river flooding, a flood picks up and carries many harmful substances that it can then deposit in your home. These can include:

  • Animal droppings
  • Drowned animals
  • Agricultural and landscaping chemicals
  • Disease-causing organisms that live in soil

As you can see, any floodwaters that come in from outside present a health hazard, which is why they're included in the "black water" category.

2. The water damage occurred several days ago.

Because of things that like to grow in water and wet areas, such as mold and mildew, water tends to get progressively dirtier and more dangerous as it sits in your house. So even if the water started out "gray" (slightly dirty water, such as a dishwasher leak) it can escalate to "black" if left for 48 hours or longer.

These two signs can help you determine whether your water damage involves "black" water. As always, contact us if you have a flood-damaged house and want more information about our clean air technology to keep air smelling fresh during cleanup.

Regardless of the intensity of your flood damage, an ozone machine will help you to kill mold and mildew to ensure a safe environment moving forward.
