Such countries include Israel, Qatar, and the United Arab Emirates. Saline water in oceans, seas and saline groundwater make up about 97% of all the water on Earth. Marcia S. Matz, M.A. That leaves only about 1 percent of Earth’s fresh water as readily available for human use. Anica Miller-Rushing, M.Ed. Approximately 69 percent of Earth’s freshwater is locked away in the form of ice in glaciers and polar ice caps, and another 30 percent of Earth’s fresh water is under the surface in the form of groundwater. Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers.

Ingber Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. Only about three percent of Earth’s water is freshwater. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Distribution of Earth's Water.
