After the Storm: The Hidden Health Risks of Flooding in a Warming World

The document highlights the link between a warming climate and the increase in heavy precipitation events across the United States. It emphasizes that while flood impacts are typically measured by property damage and immediate loss of life, there are substantial 'hidden' public health costs. These include waterborne gastrointestinal illnesses from contaminated water, respiratory and neurological problems caused by indoor mold, and increased mental health struggles. The report identifies five specific hidden risks: drowning while driving, contaminated drinking water, sewage backup in homes, contamination of recreational waterways, and toxic indoor mold. It advocates for aggressive carbon emission reductions and the creation of more resilient communities to mitigate these risks.

• Extreme precipitation events have increased across every region of the United States over the last 50 years, a trend likely to continue as temperatures rise.
• Flooding creates significant public health hazards beyond immediate trauma, including waterborne illnesses from sewage and chemical pollutants, respiratory issues from mold, and mental health problems.
• Vehicular drowning is a major cause of flood-related deaths in the U.S., with 44 percent of flood fatalities in 2010 occurring in vehicles.
• Specific infrastructure vulnerabilities, such as combined sewer overflow systems in the Northeast, Great Lakes, and Northwest regions, increase the risk of raw sewage backing up into homes during floods.
