Water Damage Restoration Technician (WRT) Certification Practice Test

Water from a clean source that poses little to no risk of sickness is categorized as what?

1. Category 2 water

2. Category 1 water

3. Category 3 water

4. Potable water

The correct answer is: Category 1 water

Water from a clean source, which poses little to no risk of sickness, is categorized as Category 1 water. This classification is used in the context of water damage restoration to indicate that the water is safe and does not contain contaminants that could cause illness. Category 1 water typically comes from sources such as a broken water supply line, tub or sink overflows, or falling rainwater, and is considered clean and sanitary. In the context of water damage restoration, the other categories are defined based on the level of contamination. For instance, Category 2 water, often referred to as "grey water," might contain some level of contamination that could cause discomfort or illness if consumed. Category 3 water, or "black water," is highly contaminated and poses a serious health risk due to pathogens and toxins it may contain, such as sewage or floodwater. The term "potable water" also describes water that is safe to drink, but it is a broader term that may not necessarily be used in the same specific contexts as the categories outlined in water damage restoration classifications. Therefore, Category 1 water aptly describes clean water sources in the restoration field, making it the correct choice for this question.
