What's the Difference: Gray or Black Water?

12/14/2022 (Permalink)

If you had flood water in your home or business recently, may have it checked out for toxic contaminants.

If your home floods, you’ll probably wonder how safe the water is.

Should you retrieve possessions from the puddles left behind? If you forgot to wear gloves and boots, will soap and water be enough to rid the germs from your hands?

Those are excellent questions.

First, you must identify the water source.

Clean water will not cause an immediate threat. It contains no contaminants and originates from toilet holding tanks, snow melt, rain, appliances such as a broken refrigerator, air conditioning units, etc.

Gray water contains chemical or biological contaminates, and therefore, may pose some health risk. It originates from washing machines, showers, sinks, aquariums, etc.

Black water causes an immediate threat due to the expected contaminants in it, including but not limited to, viruses, bacteria and protozoan. This water originates from toilets and floodwaters. Oftentimes, after a flood, water collect soils, sewage, etc. which contain harmful contaminants, which explains why it’s marked as "black water." 

However, please note that as these waters sit, they can advance to a more serious level. For instance, after sitting for two days, clean water can turn into gray water. This is why water removal should be handled immediately.

Contact with contaminated water can cause vomiting, nausea, parasitic illness and fever.

If you’re not sure of the source, contact a professional.                           

If you’re dealing with gray or black water, it’s very important to get help as soon as possible. Keep in mind that if it’s clean water, and it’s been sitting for over 48 hours, it should be treated as a gray water problem.
