What does the term "fresh water" typically refer to?

The term "fresh water" typically refers to water that is suitable for drinking. This type of water has low concentrations of dissolved salts, making it distinct from saline water found in oceans and seas. Fresh water is essential for human consumption, agricultural irrigation, and various industrial uses. Approximately 2.5% of the Earth's water is classified as fresh water, primarily found in glaciers, ice caps, rivers, lakes, and underground aquifers.

In the context of environmental health and public safety, the emphasis is often on ensuring that fresh water sources are protected from contamination and are accessible for drinking purposes. Ensuring the safety of drinking water is crucial for preventing waterborne diseases and promoting overall health. The characteristics associated with fresh water highlight its importance for sustaining life and supporting ecosystems.
