**Step-by-Step Solution:**

1. **Understanding Potable Water:**
- Potable water refers to water that is safe for human consumption. It must be clean and free from harmful contaminants that could pose health risks.

2. **Water Distribution on Earth:**
- Approximately 70% of the Earth's surface is covered by water. However, not all of this water is suitable for drinking.

3. **Types of Water:**
- The majority of Earth's water (about 96.5%) is saltwater found in oceans, which is not potable.
- Only about 2.5% of Earth's water is freshwater, which is the type of water we can drink.

4. **Sources of Freshwater:**
- Out of the 2.5% of freshwater, a significant portion (about 70%) is trapped in glaciers and ice caps, making it inaccessible for immediate use.
- The remaining freshwater is found in rivers, lakes, and underground aquifers, which are sources of potable water.

5. **Conclusion:**
- Therefore, potable water is defined as water that is clean and drinkable, primarily sourced from freshwater bodies that are not contaminated.

6. **Final Answer:**
- Potable water is that water which is clean and drinkable.
