Unpolluted freshwater supplies are commonly referred to as "pristine" or "clean" water sources. These include natural springs, glaciers, and untainted lakes and rivers that have not been contaminated by pollutants or human activities. Such sources are crucial for maintaining ecosystems, human health, and providing safe drinking water. Protecting these pristine waters is essential for environmental sustainability and biodiversity.

Through processes like evaporation, condensation, and precipitation, it maintains the balance of water necessary for plant growth, animal habitats, and overall ecological health. Additionally, the cycle helps filter pollutants and ensures that water remains clean, fostering a sustainable environment for all living organisms. This interconnected system is vital for the resilience and functionality of the biosphere.
