Potential Health Risks of Water Leaks, Flood, and Sewer Back-Up

There is a long list of potential health risks associated with water leaks, flooding, and sewer back-up that occur inside a home. In today’s blog we are going to briefly discuss some of these health risks. A complete and thorough look at every possible risk would be beyond the scope of this article. 

Water Leaks 

The health risks associated with water leaks are typically not instantaneous but longer term. If the water leaks are not addressed adequately and the area totally cleaned up, then it becomes easy for mold and mildew to grow. Fungi can proliferate at a frightening rate, and often it is unseen, growing unchecked behind walls or under floors. 

Some of these molds are extremely toxic and can quickly render a building unfit to live in. These effects would be magnified for people with allergies or with existing respiratory conditions such as COPD or asthma and also for the very young and the elderly. 


Flooding can pose the risks mentioned above with the addition of other risks. When there is flooding, water passes over the ground and can pick up chemicals and bacteria which are then dissolved in the water. 

So, then you will have the immediate risks of contamination with chemicals and/or infection from bacteria and viruses, such as those listed below. 

Sewer Back-Up 

The health risks of sewer back-up are very serious. They not only include a long list of bacteria, viruses, protozoa, and amoebas found in raw sewage, such as hepatitis and giardia, but there is also the immediate risks associated with sewer gas. 

Sewer gas can contain ammonia, hydrogen sulfide, and even carbon monoxide, just to name a few. All of these gases are harmful or fatal in large doses. The problems with all the microorganisms are that they can enter breaks in the skin causing skin or systemic infections, or someone can touch their mouth or nose or eyes and cause even more damage.
