When the Ohio River floods, it doesn’t just bring water into homes—it brings contaminated water filled with unseen dangers. Most homeowners assume floodwater is just rainwater runoff, but in reality, it often contains bacteria, sewage, chemicals, and even sharp debris.
So, yes—water from river flooding is considered contaminated, often falling into the most hazardous category of water damage. Understanding the types of floodwater, their risks, and the importance of professional cleanup can protect your home and your health.
Understanding the 3 Categories of Water Damage
When it comes to flood cleanup, restoration experts classify water into three categories:
-
Category 1 – Clean Water
-
Comes from clean sources like broken supply lines or overflowing sinks.
-
Poses little to no health risk if cleaned up quickly.
-
-
Category 2 – Gray Water
-
Contains some level of contaminants.
-
Comes from washing machines, dishwashers, or toilet overflows (without feces).
-
May cause illness if not handled properly.
-
-
Category 3 – Black Water
-
Ohio River floodwater falls into this category.
-
Highly contaminated and may contain:
-
Raw sewage
-
Industrial runoff
-
Pesticides and fuel
-
Bacteria, viruses, parasites
-
Dead animals or organic waste
-
-
Direct contact or inhalation of particles can cause serious illness or infection.
-
Once your home is exposed to Category 3 water, everything it touches must be sanitized, removed, or replaced.
Why Ohio River Floodwater Is So Dangerous
River flooding poses unique health and safety hazards that go beyond typical water damage. Here’s why:
-
It’s not just rainwater. Once water overflows from the riverbanks, it mixes with street runoff, sewage lines, chemical storage areas, and even farm waste from upstream.
-
Flooded basements become toxic zones. The water may carry harmful bacteria like E. coli, salmonella, and hepatitis A.
-
It damages more than what’s visible. Drywall, insulation, HVAC ducts, and subflooring can all absorb contaminated water.
For these reasons, river floodwater should never be cleaned with DIY methods—it requires professional safety equipment and biohazard procedures.
