Water without hydrogen would warrant warnings
Signs at park air phony hazard
The signs at the cascading pools in Waterfront Park are meant to frighten: They proclaim in bold letters, “danger” and “high levels of hydrogen.”But the warnings are bogus.
The water in the fountain pools is, like all water, made of two-thirds hydrogen atoms and one-third oxygen atoms.
So says a July 17, 2006 report in The [Louisville, Kentucky] Courier-Journal.
