Wonder if this gave them the idea to put fluoride in the water…
War surplus pure metallic sodium being disposed of after WW II…
The only remaining chemical waste was lye… wood ashes contain lye…

In what way and in what form does sodium react with water?
Elementary sodium reacts strongly with water, according to the following reaction mechanism:
2Na(s) + 2H2O → 2NaOH(aq) + H2(g)
A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction. Sodium metal is heated and may ignite and burn with a characteristic orange flame. Hydrogen gas released during the burning process reacts strongly with oxygen in the air.
A number of sodium compounds do not react as strongly with water, but are strongly water soluble.
