Maintaining Healthy Waters in Emergencies

2011 June 9

Is your water supply secure in case of an emergency or natural disaster?

By Christina Catanese

The CDC’s recent blog about emergency preparedness for the zombie apocalypse got us thinking about Healthy Waters in emergency situations, undead or otherwise.  How can the safety of water and the health of people be maintained during an emergency, and what preparations can be taken in advance to be ready for any issues you may face before, during and after an event?  Whether you are a citizen trying to protect your own health or a facility operator responsible for protecting the health of many others in your community, the best time to plan to protect your source of water is before an emergency.  And whether the emergency involves zombies, a hurricane, or floods, preparedness for water emergencies is key.

Everyone depends on a safe supply of water to operate their business, a hospital or school.  Water is needed to fight fires and it restores hope in communities hit hard by natural disasters.  But natural disasters or other emergencies can disrupt drinking water supplies and wastewater disposal systems.  Conservation or emergency disinfection orders can be issued to affected water system consumers in the aftermath of an event, if the safety of water supplies cannot be immediately ensured.

The tornado outbreak at the end of April 2011 hit states in the southeast the hardest, but in Region 3, storms in Virginia resulted in damage to a number of water systems in the southwestern part of the state, mainly because of power being knocked out by high winds. In some areas, boil water advisories were issued because the water was not safe to drink.  Water systems and water treatment plants need power to treat and distribute water, so it’s important to restore power as soon as possible, either through emergency generators or priority restoration of service.  This protects health of people (by ensuring that affected populations have access to safe drinking water), pets and water bodies (by making sure that waste gets treated before it is discharged to rivers).

Have your own septic system?  Be aware of actions you need to take to protect you and your family if your system becomes flooded.  Have a private well for your drinking water?  Check out our blog “Is your well well?” for information about how to maintain the quality of your private well or disinfect it if necessary.

There are both planning and recovery efforts in any emergency event.  That’s why EPA has provided resources on suggested pre- and post- disaster event activities to water facilities, like tabletop exercises, staff training, and facility evaluation.  EPA has also provided grants to purchase emergency generators so they have a backup source of power in case of an outage.  To learn more about emergency generators see our regional factsheet.

There’s also the Water/Wastewater Agencies Response Network, a network that lets water utilities in an emergency situation request the help of other utilities, which can provide emergency assistance, from people to equipment.  It can also be used for smaller, non-disaster emergencies, as it was recently during a water main break in Harrisburg, when nearby water companies responded to the PaWARN activation to assist with the repairs. If your utility is not a member, contact your WARN Chair.

Have you assembled an emergency kit in your house, or taken any other preparatory measures for an emergency?  Do you know of any preparations being done in your community?  Get involved with community based resiliency!
