Natural disasters or extreme weather events, like Hurricane Sandy that is headed toward the East Coast this weekend, can threaten our drinking water and wastewater infrastructure with flooding, increase peoples’ exposures to bacteria and toxins, and generally, wreak havoc on our communities.
Hurricanes can also have lasting effects on the water quality of lakes and coastal systems. Storm-related power outages are also a concern, something we all know very well here in the Washington, D.C. metro area.
Last summer, EPA, along with the U.S. Army Corps of Engineers, the Federal Emergency Management Agency, State National Guard units, and others provided drinking water to many Vermont water utilities when Tropical Storm Irene put them out of commission for an extended period of time.
During larger-scale disasters like Hurricane Katrina, or the earthquake that devastated Haiti, the recovery period is even longer. These major events require extremely innovative approaches to scaling up mobile water treatment units, developing temporary distribution systems or even relocating people to areas that have better water supplies and shelter.
Hopefully Hurricane Sandy will take it easy on us this weekend and stay farther out to sea than predicted. But in the event that we do experience flooding and power outages, here are some things you can do to make sure your water supplies are adequate and safe:
- Keep at least a 3-day supply of bottled drinking water on hand per person–and don’t forget your pets!
- Limit contact with any flood waters–they could have high levels of raw sewage or other contaminants.
In addition to these very practical suggestions, EPA scientists and engineers in the Homeland Security Research Program have published Planning for an Emergency Water Supply. This report was a joint effort with the American Water Works Association and encourages utilities and communities to consider alternative ways of providing drinking water whenever disasters strike. It contains information on how local water utilities can develop an emergency drinking water plan.
