Cleaning Up After a Flood

In the aftermath of a flood, it’s important to follow the right procedures to protect against waterborne microorganisms or other conditions that could adversely affect our health.

Drinking Water Safety

Both public and private water supplies can be compromised during extensive flooding. If you aren’t sure about the quality of your water supply, boil it before using. Wells that have become contaminated with flood waters need to be pumped out and the water tested for bacteria before drinking.

Keep a three-day supply of water on hand for emergencies – the average person will need a minimum of three U.S. gallons person per day for drinking and personal hygiene. If you have pets, keep an extra supply of drinking water on hand for them as well.

Inspecting a Flood-Damaged Home

Experts from the U.S. Federal Emergency Management Agency (FEMA) advise homeowners to use caution when re-entering their homes and to do so only after floodwaters have receded. Before entering your home, visually inspect it for the following damages that could make it unsafe to enter:

  • Inspect the foundation for cracks or other structural damage.
  • Look for broken or leaking gas lines, flooded electrical circuits, submerged furnaces or other electrical appliances that may be fire or shock hazards.
  • Check the electrical system for broken or frayed wires. If you see sparks or smell burning insulation, turn off the electricity at the main fuse box or circuit breaker. Don’t attempt to get to the circuit breaker or fuse box if you have to step in water. Call an electrician for assistance.

Bacteria and Other Microorganisms

Standing water is a perfect breeding ground for bacteria, viruses and molds. They can cause disease or even trigger allergic reactions in many people. Problems with infectious diseases can also occur if flood waters contain or have been contaminated with sewage. In addition, the longer building materials are in contact with water, the more structural damage that can potentially occur.

If your home has been deemed safe to enter, it’s important to remove standing water from the home as quickly as possible after a flood. In cases where a home’s basement has flooded, pump out the water at the rate of one-third of the water per day to reduce the potential for structural damage.

Drying or Disposing of Wet Household Goods

Dispose of all food items that have come into direct contact with flood waters. Although canned foods may appear to be salvageable, it’s best not to take chances – just throw them away.

Attempting to dry out the contents of your home can take several weeks, and if the humidity remains high, microorganisms can continue to grow. Although it may be difficult to throw certain items away, especially those with sentimental value, if the item can’t easily be dried, cleaned and sanitized, dispose of it, especially if it has come into contact with water that may contain sewage.

Don’t Let Kids Play in Flood Waters

Although all that water may look like fun, flood waters are frequently contaminated with raw sewage. Don’t let kids play in yards or streets that are under water. Be sure to wear waders, boots, rubber gloves or other protection to keep skin from being exposed to flood waters that may be microbiologically contaminated.
