Water damage is one of the most challenging emergencies a homeowner can face. If you experience flooding, it’s important to know how to respond quickly to prevent further damage. Water damage can come from multiple sources, so using specific procedures to minimize loss is essential.

Understanding the different levels of contamination in water damage

There are three main categories of contaminated water, according to the Institute of Inspection Cleaning and Restoration Certification (IICRC). These categories are based on:

  • The source of the water damage
  • The length of exposure to the structure
  • The likelihood of harmful chemicals or contaminants that may be present


It’s important to understand which category of contaminated water you’re dealing with so that you can take the appropriate steps to recover from the water damage.

What is Category 2 Water?

Category 2 water is water that may contain some amount of contamination that could be harmful to humans and animals. The most common sources of Category 2 water damage include toilet bowls containing urine, water from a dishwasher or washing machine, and sump pump failure.

What are the risks of Category 2 Water?

Category 2 water may contain harmful chemicals or bacteria that could cause serious illness if ingested. Substances like soap particles, oils, grease, food residue, bleach, hair and dead skin cells can all contribute to the contamination of Category 2 water. If left untreated, gray water can quickly turn into Category 3 water, which is extremely dangerous and can lead to death.

How to Clean Category 2 Water?

Flooding can cause a lot of damage, and every water damage issue is unique. This means that the process of cleaning up Category 2 water after a flood will vary. However, there are certain guidelines that may be useful for mitigating damage. These guidelines may include the following:

-The EPA and IICRC recommend that you remove all standing water as soon as possible. This will help to prevent further damage and mold growth.

-You should also remove all wet items from the affected area. This includes carpeting, furniture, and anything else that may be soaked.

-You will need to dry the affected area as much as possible. This can be done with fans, dehumidifiers, or by opening windows and doors.

-Once the area is dry, you can begin cleaning and disinfecting surfaces.

Following these guidelines may help to minimize damage after a flood.
