The rather narrow range of concentration of potassium observed in natural water suggests a significant chemical control mechanism may be involved. Two general principles which have been referred to are the resistance to solution exhibited by potassium feldspar, and the apparent preferential incorporation of potassium into clay or mica minerals.
Potassium (K) and water - Lenntech
In what way and in what form does potassium react with water? Potassium reacts rapidly and intensely with water, forming a colourless basic potassium hydroxide solution and hydrogen gas, according to the following reaction mechanism: 2K (s) + 2H 2 O (l) -> 2KOH (aq) + H 2 (g)

Potassium in Water - Basic Water Science 101
Potassium is always present in considerable amounts in the most unmineralized waters. This leaves nitrogen and phosphorus as the two plant nutrient elements which are most likely to be important. Potassium in water seems to be rarely, if ever, a …
Potassium (K) In Water - Olympian Water Testing
Potassium is an essential trace element in humans and is rarely found in water in amounts that could be detrimental to health [1]. This element occurs widely in natural water and can also be found in drinking water. In drinking water, it occurs due …

Potassium is a soft, silvery-white metal with a melting point of 63°C (145°F) and a boiling point of 770°C (1,420°F). Its density is 0.862 grams per cubic centimeter, less than that of water (1.00 grams per cubic centimeter). That means that potassium metal can float on water.
Potassium in Water - School Science Fair Water 101 by Dr.
Potassium is liberated with greater difficulty from silicate minerals and exhibits a strong tendency to be reincorporated into solid weathering products, especially certain clay minerals. In most natural waters, the concentration of potassium is much lower than the concentration of sodium.
Potassium is an essential element in humans and is seldom, if ever, found in drinking-water at levels that could be a concern for healthy humans. The recommended daily requirement is greater than 3000 mg. Potassium occurs widely in the environment, including all natural waters.
