Types of Water Contamination After a Flood

While most developed countries have set measures to counter flooding, sewage backup disasters, water damage, finding areas affected during rainstorms is not unusual. Sometimes, the rain pours so heavily that the measures put in place cannot stop the water from destroying property. This is why most people have their homes insured against flood damage.

Regardless of the disaster’s nature, a flood can be perilous. It’s essential to comprehend the many floodwater types that cause contamination and the toxins they encompass if you want to stay safe. This mainly applies to private drinking water wells subjected to contamination following flooding.

Types of Water Contamination After a Flood

When people talk about flooding, they mostly think of hazards such as drowning, electrocution, and other accidents that can occur in the event of a flood. Additionally, contamination, one of the major effects of flooding, poses a significant threat to your well-being and should be taken into account. There are three main categories of floodwater you should consider.

Clean Water

Clean water is defined as floodwater that poses no imminent harm to health. It appears apparent, no? Floods containing clean water can be caused by broken equipment, overflowing toilets, melting ice, and rainfall. Home floods caused by clean water are typically safe to clear on your own, but keep in mind that timing is pivotal. When the standing clean water remains in the same position for more than 48 hours, it becomes impure and unsafe for you to handle. 


Floodwater that is not feces-contaminated is known as greywater. Greywater is domestic wastewater, including water from sinks, washers, dryers, dishwashers, and bathrooms. It often has fewer bacteria and can be recycled for uses other than drinking, including flushing toilets. This water can make you ill if you swallow it since it still has trace quantities of pollutants.

Greywater flooding can be brought on by a weather phenomenon, an overloaded device or plumbing accessory, or even a damaged pipeline. It can soak up carpeting, furnishings, and drywall, causing significant damage. When starting the cleaning procedure after a greywater flood in your home, exercise caution. Once clean flood water mixes with grey water, it becomes toxic.


This is wastewater that has been polluted with feces or other garbage. Blackwater, produced by flush toilets and bidets, includes toilet tissue and human excrement, including urine and feces. Water from dishwashing sinks used for preparing meals and other origins can also be considered blackwater. 

Blackwater is a category for untreated sewage. Harmful germs and microbes must completely degrade in blackwater to be discharged into the environment. Contact with it is dangerous if it is polluted with dissolved chemicals and particles. When a heavy downpour causes flooding, it is highly plausible that black water mixes with the flood water.


After a flood, many things cause water contamination, including heating oils, industrial waste, and agricultural and industrial chemicals. This is why people with private drinking water wells are advised to keep away from the water after flooding. Ingesting these contaminants can present significant health risks. Ensure your private drinking water well is regularly inspected and tested for safety if you live in a flood-prone area.
