What defines Category 3 water?

1. Water suitable for drinking

2. Water that contains pathogens or harmful agents

3. Water that is slightly contaminated

4. Rainwater or natural sources

The correct answer is: Water that contains pathogens or harmful agents

Category 3 water is defined by its potential to contain pathogens or harmful agents that can pose serious health risks to humans. This classification includes water that has been contaminated by sewage, floods, or other sources that introduce bacteria, viruses, and toxic substances. Such water is also referred to as "black water" and can cause severe illness if ingested or if it comes into contact with the skin. Understanding the implications of exposure to Category 3 water is crucial in mold remediation processes, as it directly influences the safety protocols and remediation strategies employed to protect both the workers and occupants of a property. Other classifications, such as water that is suitable for drinking, slightly contaminated water, or natural sources like rainwater, do not meet the criteria for Category 3, as they do not carry the same level of health risk associated with pathogens and harmful substances.
