BLOG: Flooding, Groundwater Contamination, and Your Family’s Safety

by Sally Phillips, freelance writer

All 50 states in the U.S. have experienced some level of flooding in recent years. It is the #1 natural disaster in the country, and from 2005 to 2014, flood insurance claims amounted to an average of $3.5 billion annually.  

But it’s not all about flood claims and fixing structures that were damaged by such a disaster. A less visible threat is water contamination after a major flood. Groundwater contamination is a big concern, as 50% of the country’s population get their drinking water from groundwater resources. It is also the country’s primary irrigation source.

How can flooding threaten groundwater?

In the event of a flood, contaminants from septic tanks, farms, storage tanks, uncontrolled hazardous waste, and landfills can flow into floodwaters. As the water subsides, these contaminants can enter groundwater. Water contamination following a flood can lead to serious waterborne diseases such as cholera, dysentery, and the like, affecting both public water systems and those relying on private wells for drinking water.

Contaminants from uncontrolled hazardous waste alone is a scary prospect. There are thought to be over 20,000 abandoned and uncontrolled sites in the United States today and if these areas are flooded, contaminants will find their way to the water source.

Living in a Flood Prone Area

If you live in a flood prone area, it is important to check your homeowners insurance for flood coverage, since many homeowners plans don't include flood damage. An average insurance claim of $42,000 are filed by American families after every flood. This is a huge expense for most families, which is why ensuring that you have flood coverage is very important. As experts say, it is better to have it and not need it than not to have it and need it.

Preparing for a Flood

Considering climate change and the natural disasters it has brought in the past decade, it is vital to be prepared for flash floods or flooding. Families can prepare for this type of natural disaster by assembling emergency kits and having basic items ready. Having crates for your pets is also a must. It is also advised that you prepare bug-out bags for your four-legged family members too. Preparing an escape plan is just as important. Knowing the routes to find higher ground is a great idea. Experts note that you should know these routes by heart so that you can keep your whole family safe. Making advance arrangements for a place to stay is also a good idea.

Apart from being prepared, one of the most important things to remember after a flood is to be careful of the water you drink. It is best to have bottled water on hand so you don’t have to drink water from the tap until supplies are safe after a flood event, helping protect you and your family from diseases brought about by possible water contamination.
