The 3 Cleanest Water Sources in the World

Jun 03 2015

Clean water is hard to come by despite the fact that the earth is made up of about 71% water. Why is this? Of all the water on our planet, less than 3% is fresh, clean water. This makes clean water sources extremely valuable especially Lake Vostok, Crater Lake and Lake Baikal which are considered the purest and cleanest water sources in the world.

In this article, you will learn about each of the three lakes that claim to have some of the cleanest water on Earth.

Lake Vostok, Antarctica

lake-vostok-waterLake Vostok is the largest sub glacial lake in Antarctica. It is located at the southern Pole of Cold beneath the Russian Vostok Station. It is about 4,000 feet under the surface of the central East Antarctic Ice Sheet and covers an area of 4,830 square miles with an average depth of 1,417 ft. The lake water was sealed off under the ice sheet for about 15 million years ago so it has been free of contamination by human pollutants.

In 2012, Russian scientists completed the longest ever ice core of 12,400 feet and pierced the ice shield to the surface of the lake. It was then discovered that the water that makes up Lake Vostok is more than twice as pure as double distilled mineral water, making it some of the cleanest and purest water known to humanity.

Crater Lake, United States


Crater Lake was formed about 7,700 years ago when the volcano Mount Mazama collapsed during an eruption, creating a massive crater in the earth (hence the lake’s name). A unique characteristic about Oregon’s Crater Lake is that its water comes purely from snow and rainfall. An alarming amount of snow and rain must make up the lake considering it is five by six miles across with an average depth of 1,148 feet.

There are no rivers, creeks, or any other sources of water that flow in and out of the lake. Because of this, Crater Lake does not get polluted by outside sources and is said to have some of the purest and cleanest water.

Lake Baikal, Siberia

lake-baikal-siberia-waterLake Baikal located in the southern part of Siberia is the largest freshwater lake in the world by volume, containing 20% of the world’s unfrozen surface fresh water. Not only is Lake Baikal the largest freshwater lake, but it is the oldest and deepest freshwater lake as well. It is home to more than 2,000 species of plants and animals; two thirds of which cannot be found anywhere else in the world.

Of the 2,000+ species in the lake include the zooplankton species: the organisms responsible for keeping the water clean and making Lake Baikal one of the cleanest water sources on the planet.


Now that you know about some of the cleanest, purest water sources in the world, you probably wish you could go to each of the lakes and taste the water to see just how refreshing it really is. Although this is a bit unrealistic for the average person, you can still experience something close to it from your own tap. Investing in a water purification system will give you water that tastes like the purest, cleanest water in the world compared to regular tap water that has various contaminants and strange tastes.
