Floodwater and contamination

Most floodwater is unsanitary at best and infested with dangerous bacteria at worst, experts find, and recent storms in Davenport have brought to light the issues with rising water levels and contamination.

River water is a typical site for sewage and stormwater runoff. It’s also a source of energy, transport, and water for commercial and residential use; the Mississippi alone provides drinking water for some 18 million people.

But flooding disrupts the water purification process and pushes much of the contaminated water out, especially when storm drains become compromised. Spring typically brings heavy rain and an increase in water levels, but concentrated snowfall and changing weather patterns have caused the Mississippi to spill over in several cities. In Davenport, citizens know not to wander in the water: floodwater around the Modern Woodman park baseball stadium tested positive for E. Coli.

Most bacteria found in floodwater causes gastrointestinal issues, and staying safe from these contaminants is one of the recommended ways to deal with flooding, according to OSHA. Infection and sickness are just some of the risks following any natural disaster that causes floods, and staying out of the water is the best way to stay safe.
