Boron (B) and water - Water Treatment and Purifiion

Boron salts are generally well water soluble. Boric acid has a water solubility of 57 g/L, borax of 25.2 g/L, and boron trioxide of 22 g/L. Boron trifluoride is the least water soluble boron compound, with a water solubility of 2.4 g/L. Some boron compounds, such as boron nitrite are completely water insoluble. Why is boron present in water?
