What percent is directly available from lakes rivers and groundwater?

Approximately 2.5% of the Earth's water is freshwater, and of that, only about 1% is directly available for human use from lakes, rivers, and groundwater. This means that roughly 0.025% of the total water on Earth is easily accessible for drinking, irrigation, and other purposes. The majority of freshwater is locked in glaciers and ice caps, making it inaccessible for immediate use.
