In 2006, David Karem, executive director of the Waterfront Development Corporation, a public agency that operates Waterfront Park, wished to deter visitors from bathing in the large public fountain. He initiated a plan that was dependent on the average park visitor's "lack of understanding about water's chemical makeup", and arranged for signs that read: "DANGER! – WATER CONTAINS HIGH LEVELS OF HYDROGEN – KEEP OUT". The signs were posted on the fountain at public expense. As it is true that ordinary water molecules each contain two atoms of hydrogen, and thus posed no danger, it is considered one of many water-related hoaxes.
