THE DISASTER AFTER THE DISASTER The Societal Impacts of a Health-Care Disaster After a Flood Disaster can Equal or Eclipse the Flood’s Impacts Dr. Walter Hays, Global Alliance For Disaster Reduction
WHAT CAN HAPPEN AFTER THE FIRST DISASTER WATER BORNE AND WATER RELATED DISEASES POLLUTION ENVIRONMENTAL DEAD ZONES
WATER BORNE AND WATER RELATED DISEASES When the water begins to recede after a regional flood, government officials should warn of the health- care risks from dangerous bacteria and the diseases they cause, mosquitoes (in some cases), and pollution.
E-COLI AND TETNUS The flood waters that seep into water wells across a flooded region will cause health problems related to the reduction in the quality of drinking water for tens of thousands.
E-COLI AND TETNUS Hazardous materials that leach into the flood waters will exacerbate the danger.
MOULD Mold, which begins growing within 24 hours, can cause severe allergic reactions and potentially fatal respiratory seizures,
POLLUTION Flood waters loaded with fertilizer and runoff with farm debris dramatically increases soil and water pollution along an entire river system (e.g., the Mississippi River) and adds to or starts new “dead zones.”
ENVIRONMENTAL DEAD ZONE A dead zone is a region that gradually becomes starved for oxygen, and, over time, reaches the point where it can not sustain fish, or any other aquatic life.
The “dead zone” in the Gulf of Mexico, the largest in the Western Hemisphere, was caused by pollutants that entered the Mississippi River system after annual flooding.
SOCIOECONOMIC IMPACTS A Presidential disaster declaration 17 deaths Thousands evacuated Damaged homes and infrastructure Environmental impacts Clean up cost in the multi-millions Multi-state flooding expected after regional runoff
FLOODS IN MIDWESTERN USA Heavy prolonged rainfall of at least 30 cm (12 in) from a large storm system caused flooding in Texas, Arkansas, Missouri, Kentucky, Ohio, Illinois, and Indiana
