Recovering from Flood Damage: 3 Things You Should Know About Gray or Black Water

flood damage

The recent string of devastating natural disasters across North America had us in the environmental remediation industry thinking a lot about gray and black water. There’s many ways gray or black water can occur – but the primary cause in a residence is due to flooding from rainwater leaks, groundwater intrusion, pipe bursts, sewage back-ups, and raised rivers, lakes, and oceans due to storms and hurricanes.

It’s a topic that’s not always at the forefront of folks’ minds, but there are valuable steps that can be made when you experience gray or black water that will protect you and the rest of the world from increased pollution caused when flood waters pass through a home in the future. Here’s what you need to know:

  • What is the difference between gray and black water?

Gray water may cause a health risk since the waters may contain chemical or biological contamination. These waters include discharges from dishwashers, washing machines, sinks, showers, aquariums and waterbeds.

Black water is a definite health risk. These waters may contain multiple and potentially harmful contaminants. It includes floodwaters containing soil and any sewage waters. All raw sewage is contaminated with microbes, including bacteria, protozoans, molds, fungi and viruses, many of which are pathogenic to humans. Microbes from this source certainly cause many diseases.

If gray water is not dealt with in the first 48 hours of being in a residence, it becomes black water.

  • Gray or black water is present. Now what?

Time is of the essence. The top priority should be to dry out the property as soon as possible. If the property is dried out within 48 hours and the source of the problem has ceased, further problems are unlikely from the contaminated water.

  • What help exists for remediating?

Luckily, New England has been mostly scathed in the past year for natural disasters, but we’re still susceptible to the same things that Texas, Florida, and Puerto Rico experienced early this year.
