Building Reentry

Prior to entering any property that has been evacuated due to flooding, it is important to ensure that it is safe. This includes checking for structural damage and electrical and gas safety.  Also be aware of contaminants that may be present in the air and remaining water and silt. The following documents have guidelines on reentering a flooded property:

Water Quality

After a flood, tap or well water may not be safe to drink, or even to use for cleaning and bathing.  To make sure your water is safe, if you are connected to a public water supply, listen to state and local officials who will give information on the status of your water. If you are on private well water, and you know or suspect that your well has been compromised by flood water, stop using the water until the well can be inspected and tested. The Iowa Department of Natural Resources (DNR) has instructions for dealing with flooded wells. Click here to access What Should I do When My Well Floods.


Private Septic Systems

Flooded septic systems can be hazardous for homeowners and to the system.  Iowa Department of Public Health (IDPH) has instructions for Flooded Private Sewage Systems.

Flood Cleanup & Mold

While cleaning up after a flood, it can be difficult to determine what can be cleaned and what needs to be discarded, and the most effective way to clean and make repairs so that both people and property are protected. Mold, in particular, can cause serious problems.  Following are several documents that will help residents as they begin the process of cleanup:

In addition, if your home heating, ventilation, and air-conditioning unit could have been contaminated by floodwater or mold, have it checked out and cleaned by a service professional before you turn it on. This can help prevent the mold contamination from being spread throughout your home.


Hiring a Reputable Contractor

Property owners that intend to hire a contractor will want to make sure they are hiring a company that is reputable and can properly do the work that needs to be done. Iowa State Extension has good guidance for Hiring Contractors After a Disaster.

Carbon Monoxide Poisoning

If you or a contractor will be using gas-powered equipment such as generators or pressure washers during the cleanup process, it is extremely important that they are well-ventilated.  Carbon monoxide fumes can build up and become harmful or even fatal.  You cannot see or smell this gas. Be sure to:

  • NEVER place gas generated equipment such as pressure washer engines indoors during use.
  • NEVER place gas generated equipment such as pressure washer engines in a garage or other enclosed space during use.
  • NEVER place gas generated equipment such as pressure washer engines near open windows, doors, or vents during use.
  • Check out the fact sheet on Carbon Monoxide Poisoning Prevention.



Floodwaters provide excellent breeding grounds for mosquitoes. Check out the fact sheets Mosquito Bite Prevention and Use of Mosquito Repellant on Children to help protect yourself and your family from mosquitoes, including those that transmit disease such as the West Nile virus. 


Sandbag Disposal

The Iowa DNR is reminding residents that, in most cases, sand from sandbags is not hazardous and can be reused.  It should not; however, be used in children’s play areas.  Empty bags can be placed in the trash and sent to a landfill.  To read the DNR’s statement on sand bag reuse, click here.


Staying Healthy

Sometimes, when dealing with a disaster, people can overlook basic strategies to keep themselves healthy.  This can include using proper personal protective equipment during the cleanup process, ensuring you are up to date on your vaccinations, and basic personal hygiene.

Proper personal protective equipment during cleanup will include

  • Closed-toe, hard-sole boots or shoes
  • Proper gloves
  • An N-95 or higher rated respirator (these are widely available at hardware stores)
  • Goggles
  • Long pants and long-sleeved shirt


Vaccination and basic hygiene information is available on the fact sheets Immunization Recommendations and Flood Hygiene.

Always consult your healthcare provider if you have any health issues that may be a concern, such as respiratory problems, severe allergies, or a compromised immune system.
