Which of the following is an example of Category 3 Water?

Category 3 water is water that is grossly contaminated with pathogens and hazardous substances, usually from floodwaters, sewage, or water that has picked up contaminants from soil or waste. Water from rising rivers fits this because floods wash in soil, debris, and often sewage or other pollutants, making the water highly contaminated and requiring special handling. In contrast, condensation on a window is essentially clean water formed from vapor, so it’s Category 1. Groundwater from a clean aquifer is also clean, Category 1, assuming there’s no underground contamination. Rainwater runoff can vary in contamination level, but it’s not automatically Category 3; it can be Category 1 or 2 depending on what it has contacted.
