Over 99% of the population's water supply comes from fresh water sources such as lakes, tarns, rivers and ground water. There are however three water works in Norway taking use of desalination of sea water and all of them are located in the county of Nordland , only providing around 500 people with water.
Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. 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.

In 1960, the Aral Sea was the world's twelfth-largest known lake by volume, at 1,100 km 3 (260 cu mi). However, by 2007 it had shrunk to 10% of its original volume and was divided into three lakes, none of which are large enough to appear on this list. [17]
Ricin is easily denatured by temperatures over 80 °C (176 °F) meaning many methods of deploying ricin would generate enough heat to denature it. [35] Once deployed, an area contaminated with ricin remains dangerous until the bonds between chain A or B have been broken, a process that takes two or three days. [ 8 ]
